waf-dg-394 | waf-dg.pdf | 394 | Firewall Manager quotas. iii. For Policy action, you must create the policy with the option that doesn't automatically remediate. This allows you to assess the effects of your new policy before you apply it. When you are satisfied that the changes are what you want, edit the policy and change the policy action to enable automatic remediation of noncompliant resources. 10. Choose Next. 11. For AWS accounts this policy applies to, choose the option as follows: Creating a policy 1054 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • If you want to apply the policy to all accounts in your organization, leave the default selection, Include all accounts under my AWS organization. • If you want to apply the policy only to specific accounts or accounts that are in specific AWS Organizations organizational units (OUs), choose Include only the specified accounts and organizational units, and then add the accounts and OUs that you want to include. Specifying an OU is the equivalent of specifying all accounts in the OU and in any of its child OUs, including any child OUs and accounts that are added at a later time. • If you want to apply the policy to all but a specific set of accounts or AWS Organizations organizational units (OUs), choose Exclude the specified accounts and organizational units, and include all others, and then add the accounts and OUs that you want to exclude. Specifying an OU is the equivalent of specifying all accounts in the OU and in any of its child OUs, including any child OUs and accounts that are added at a later time. You can only choose one of the options. After you apply the policy, Firewall Manager automatically evaluates any new accounts against your settings. For example, if you include only specific accounts, Firewall Manager doesn't apply the policy to any new accounts. As another example, if you include an OU, when you add an account to the OU or to any of its child OUs, Firewall Manager automatically applies the policy to the new account. 12. For Resource type, choose the types of resource that you want to protect. 13. For Resources, you can narrow the scope of the policy using tagging, by either including or excluding resources with the tags that you specify. You can use inclusion or exclusion, and not both. For more information about tags to define policy scope, see Using the AWS Firewall Manager policy scope. Resource tags can only have non-null values. If you omit the value for a tag, Firewall Manager saves the tag with an empty string value: "". Resource tags only match with tags that have the same key and the same value. 14. Choose Next. 15. Review the policy settings to be sure they're what you want, and then choose Create policy. Firewall Manager compares the audit security group against the in-scope security groups in your AWS organization, according to your policy rules settings. You can review the policy status in the AWS Firewall Manager policy console. After the policy is created, you can edit it and enable Creating a policy 1055 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide automatic remediation to put your auditing security group policy into effect. For more information about how this policy works, see Using content audit security group policies with Firewall Manager. Creating an AWS Firewall Manager usage audit security group policy For information about how usage audit security group policies work, see Using usage audit security group policies with Firewall Manager. To create a usage audit security group policy (console) 1. Sign in to the AWS Management Console using your Firewall Manager administrator account, and then open the Firewall Manager console at https://console.aws.amazon.com/wafv2/ fmsv2.

For details about how Firewall Manager determines usage and the timing of the remediation, see Using usage audit security group policies with Firewall Manager. Creating a policy 1056 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Note When you use this usage audit security group policy type, avoid making multiple changes to the association status of in-scope security groups in a short amount of time. Doing so can cause Firewall Manager to miss corresponding events. By default, Firewall Manager considers security groups as noncompliant with this policy rule as soon as they're unused. You can optionally specify a number of minutes that a security group can exist unused before it's considered noncompliant, up to 525,600 minutes (365 days). You can use this setting to allow yourself time to associate new security groups with resources. Important If you specify a number of minutes other than the default value of zero, you must enable indirect relationships in AWS Config. Otherwise, your usage audit security group policies will not work as intended. For information about indirect relationships in AWS Config, see Indirect Relationships in AWS Config in the AWS Config Developer Guide. • If you choose Security groups within this policy scope must be unique, Firewall Manager consolidates redundant security groups, so that only one is associated with any resources. If you choose this, Firewall Manager runs it first when you save the policy. 10. For Policy action, we recommend creating the policy with the option that doesn't automatically remediate. This allows you to assess the effects of your new policy before you apply it. When you are satisfied that the changes are what you want, then edit the policy and change the policy action to enable automatic remediation of noncompliant resources. 11. Choose Next. 12.

For Policy rules, define the rules that you want to always run in the network ACLs that Firewall Manager manages for you. Network ACLs monitor and handle inbound and outbound traffic, so in your policy, you define the rules for both directions. For either direction, you define rules that you want to always run first and rules you want to always run last. In the network ACLs that Firewall Manager manages, account owners can define custom rules to run in between these first and last rules. Creating a policy 1059 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide 9. For Policy action, if you want to identify noncompliant subnets and network ACLs, but not take any corrective action yet, choose Identify resources that don't comply with the policy rules, but don't auto remediate. You can change these options later. If instead you want to automatically apply the policy to existing in-scope subnets, choose Auto remediate any noncompliant resources. With this option, you also specify whether to force remediation when the traffic handling behavior of policy rules conflicts with custom rules that are in the network ACL. Regardless of whether you force remediation, Firewall Manager reports conflicting rules in its compliance violations. 10. Choose Next. 11. For AWS accounts this policy applies to, choose the option as follows: • If you want to apply the policy to all accounts in your organization, leave the default selection, Include all accounts under my AWS organization. • If you want to apply the policy only to specific accounts or accounts that are in specific AWS Organizations organizational units (OUs), choose Include only the specified accounts and organizational units, and then add the accounts and OUs that you want to include.

Using the AWS Firewall Manager policy scope This page explains what the Firewall Manager policy scope is and how it works. The policy scope defines where the policy applies. You can apply centrally controlled policies to: • All of your accounts and resources within your organization in AWS Organizations. • A subset of your accounts and resources within your organization in AWS Organizations. For instructions on how to set policy scope, see Creating an AWS Firewall Manager policy. Deleting a policy 1075 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Policy scope options in AWS Firewall Manager When you add a new account or resource to your organization, Firewall Manager automatically assesses it against your settings for each policy and applies the policy based on these settings. For example, you can choose to apply a policy to all accounts except the account numbers in a specified list. Resource tags can also be used to define policy scope. You can choose to apply a policy by excluding or including resources that have all of the tags in a list. Alternatively, you can choose to apply a policy only to resources that have any of a specified tag in a list. AWS accounts in scope The settings that you provide to define the AWS accounts affected by the policy determine which of the accounts in your AWS organization to apply the policy to. You can choose to apply the policy in one of the following ways: • To all accounts in your organization • To only a specific list |

For more information about tagging your resources, see Working with Tag Editor. Policy scope management in AWS Firewall Manager When policies are in place, Firewall Manager manages them continuously and applies them to new AWS accounts and resources as they are added, in accordance with the policy scope. How Firewall Manager manages AWS accounts and resources If an account or resource goes out of scope for any reason, AWS Firewall Manager doesn't automatically remove protections or delete Firewall Manager-managed resources unless you select the Automatically remove protections from resources that leave the policy scope check box. Note The option Automatically remove protections from resources that leave the policy scope is not available for AWS Shield Advanced or AWS WAF Classic policies. Selecting this check box directs AWS Firewall Manager to automatically clean up resources that Firewall Manager manages for accounts when those accounts leave the policy scope. For example, Firewall Manager will disassociate a Firewall Manager-managed web ACL from a protected customer resource when the customer resource leaves the policy scope. To determine which resources should be removed from protection when a customer resource leaves the policy scope, Firewall Manager follows these guidelines: • Default behavior: • The associated AWS Config managed rules are deleted. This behavior is independent of the check box. • Any associated AWS WAF web access control lists (web ACLs) that don't contain any resources are deleted. This behavior is independent of the check box. • Any protected resource that goes out of scope remains associated and protected. For example, an Application Load Balancer or API from API Gateway that's associated with a web ACL remains associated with the web ACL, and the protection remains in place. Using the policy scope 1077 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • With the Automatically remove protections from resources that leave the policy scope check box selected: • The associated AWS Config managed rules are deleted. This behavior is independent of the check box. • Any associated AWS WAF web access control lists (web ACLs) that don't contain any resources are deleted. This behavior is independent of the check box. • Any protected resource that goes out of scope is automatically disassociated and removed from Firewall Manager protection when it leaves the policy scope. For example, for a security group policy, an Elastic Inference accelerator or Amazon EC2 instance is automatically disassociated from the replicated security group when it leaves the policy scope. The replicated security group and its resources are automatically removed from protection. Using AWS WAF policies with Firewall Manager This section explains how to use AWS WAF policies with Firewall Manager. In a Firewall Manager AWS WAF policy, you specify the AWS WAF rule groups that you want to use to protect all resources that are within policy scope. When you apply the policy, Firewall Manager begins managing web ACLs for in-scope resources, using the specified rule groups and other policy configurations. You can configure the policy to create and manage all new web ACLs for in-scope resources, replacing any web ACLs that are already in |
waf-dg-406 | waf-dg.pdf | 406 | resources are automatically removed from protection. Using AWS WAF policies with Firewall Manager This section explains how to use AWS WAF policies with Firewall Manager. In a Firewall Manager AWS WAF policy, you specify the AWS WAF rule groups that you want to use to protect all resources that are within policy scope. When you apply the policy, Firewall Manager begins managing web ACLs for in-scope resources, using the specified rule groups and other policy configurations. You can configure the policy to create and manage all new web ACLs for in-scope resources, replacing any web ACLs that are already in use. Alternately, you can configure the policy to keep any web ACLs that are already associated with in-scope resources, and retrofit them for use by the policy. With this second option, Firewall Manager only creates new web ACLs for resources that don't already have a web ACL association. Regardless of how they're created, in the web ACLs that Firewall Manager manages, individual accounts can manage their own rules and rule groups, in addition to the rule groups that you define in the Firewall Manager policy. For the procedure to create a Firewall Manager AWS WAF policy, see Creating an AWS Firewall Manager policy for AWS WAF. Rule group management for AWS WAF policies The web ACLs that are managed by Firewall Manager AWS WAF policies contain three sets of rules. These sets provide a higher level of prioritization for the rules and rule groups in the web ACL: AWS WAF policies 1078 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • First rule groups, defined by you in the Firewall Manager AWS WAF policy. AWS WAF evaluates these rule groups first. • Rules and rule groups that are defined by the account managers in the web ACLs. AWS WAF evaluates any account-managed rules or rule groups next. • Last rule groups, defined by you in the Firewall Manager AWS WAF policy. AWS WAF evaluates these rule groups last. Within each of these sets of rules, AWS WAF evaluates rules and rule groups as usual, according to their priority settings within the set. In the policy's first and last rule groups sets, you can only add rule groups and not individual rules. You can use managed rule groups, which AWS Managed Rules and AWS Marketplace sellers create and maintain for you. You can also manage and use your own rule groups. For more information about all of these options, see AWS WAF rule groups. If you want to use your own rule groups, you create those before you create your Firewall Manager AWS WAF policy. For guidance, see Managing your own rule groups. To use an individual custom rule, you must define your own rule group, define your rule within that, and then use the rule group in your policy. The first and last AWS WAF rule groups that you manage through Firewall Manager have names that begin with PREFMManaged- or POSTFMManaged-, respectively, followed by the Firewall Manager policy name, and the rule group creation timestamp, in UTC milliseconds. For example, PREFMManaged-MyWAFPolicyName-1621880555123. For information about how AWS WAF evaluates web requests, see Using web ACLs with rules and rule groups in AWS WAF. Firewall Manager enables sampling and Amazon CloudWatch metrics for the rule groups that you define for the AWS WAF policy. Individual account owners have complete control over the metrics and sampling configuration for any rule or rule group that they add to the policy's managed web ACLs. Web ACL management for AWS WAF policies Firewall Manager creates and manages web ACLs for in-scope resources according to your configuration settings and general policy management. AWS WAF policies 1079 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Note If a resource that's configured with advanced automatic application layer DDoS mitigation comes into scope of an AWS WAF policy, Firewall Manager will be unable to apply the policy protections to the resource and will mark the resource noncompliant. Manage unassociated web ACLs configuration Policy configuration setting that specifies how Firewall Manager manages web ACLs for accounts when the web ACLs won't be used by any resource. If you enable management of unassociated web ACLs, Firewall Manager creates web ACLs in accounts that are within policy scope only if the web ACLs will be used by at least one resource. If you don't enable this option, Firewall Manager automatically ensures that each account has a web ACL regardless of whether the web ACL will be used. When this is enabled, when an account comes into policy scope, Firewall Manager automatically creates a web ACL in the account only if at least one resource will use the web ACL. Additionally, when you enable management of unassociated web ACLs, at policy creation, Firewall Manager performs a one-time cleanup |
waf-dg-407 | waf-dg.pdf | 407 | Manager creates web ACLs in accounts that are within policy scope only if the web ACLs will be used by at least one resource. If you don't enable this option, Firewall Manager automatically ensures that each account has a web ACL regardless of whether the web ACL will be used. When this is enabled, when an account comes into policy scope, Firewall Manager automatically creates a web ACL in the account only if at least one resource will use the web ACL. Additionally, when you enable management of unassociated web ACLs, at policy creation, Firewall Manager performs a one-time cleanup of unassociated web ACLs in your account. During this cleanup, Firewall Manager skips any web ACLs that you've modified after their creation, for example, if you added a rule group to the web ACL or modified its settings. The cleanup process can take several hours. If a resource leaves policy scope after Firewall Manager creates a web ACL, Firewall Manager disassociates the resource from the web ACL, but won't clean up the unassociated web ACL. Firewall Manager only cleans up unassociated web ACLs when you first enable management of unassociated web ACLs in a policy. In the API, this setting is optimizeUnassociatedWebACL in the SecurityServicePolicyData data type. Example: \"optimizeUnassociatedWebACL\":false Web ACL source configuration: Create all new or retrofit existing? Policy configuration setting that specifies what Firewall Manager does with existing web ACLs that are associated with in-scope resources. By default, Firewall Manager creates all new web ACLs for in-scope resources. With retrofitting, Firewall Manager uses any existing web ACLs that are already in use, and only creates new web ACLs for resources that don't already have one associated. AWS WAF policies 1080 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide When a policy is configured for retrofitting, all web ACLs that are associated with in-scope resources are retrofitted or marked noncompliant. Firewall Manager only retrofits a web ACL if it satisfies the following requirements: • The web ACL is owned by a customer account. • The web ACL is only associated with in-scope resources. Tip Before you configure an AWS WAF policy for retrofitting, make sure that the web ACLs that are associated with the policy's in-scope resources aren't associated with any out-of- scope resources. Tip If you want to delete an associated resource, first disassociate it from the web ACL. If a web ACL is noncompliant due to an association with an out-of-scope resource, deleting the out-of-scope resource without first disassociating it from the web ACL can bring the web ACL into compliance, and Firewall Manager can then retrofit the web ACL through remediation, but the remediation in this situation can be delayed by up to 24 hours. For information about accessing compliance violation details, see Viewing compliance information for an AWS Firewall Manager policy. If a web ACL can be retrofitted, Firewall Manager modifies it as follows: • Firewall Manager inserts the AWS WAF policy's first rule groups in front of the web ACL's existing rules and appends the AWS WAF policy's last rule groups at the end. For information about rule group management, see Rule group management for AWS WAF policies. • If the policy has a logging configuration, then Firewall Manager adds it to the web ACL only if the web ACL isn't already configured for logging. If the web ACL has logging configured by the account, Firewall Manager leaves it in place both during the retrofitting and for any subsequent updates to the policy's logging configuration. • Firewall Manager doesn't verify or configure any other web ACL properties. For example, Firewall Manager doesn't modify the web ACL's default action, custom request headers, CAPTCHA or AWS WAF policies 1081 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Challenge configurations, or token domain lists. Firewall Manager only configures these other properties on web ACLs that Firewall Manager creates. After Firewall Manager retrofits all existing associated web ACLs, for any in-scope resource that doesn't have a web ACL, Firewall Manager handles the resource following the default policy behavior. If it's a resource that AWS WAF can protect, then Firewall Manager creates and associates a Firewall Manager web ACL with that resource. In the API, the web ACL source setting is webACLSource in the SecurityServicePolicyData data type. Example: \"webACLSource\":\"RETROFIT_EXISTING\" Sampling and CloudWatch metrics AWS Firewall Manager enables sampling and Amazon CloudWatch metrics for the web ACLs and rule groups that it creates for an AWS WAF policy. Web ACL naming A web ACL that Firewall Manager creates is named after the AWS WAF policy as follows: FMManagedWebACLV2-policy name-timestamp. The timestamp is in UTC milliseconds. For example, FMManagedWebACLV2-MyWAFPolicyName-1621880374078. A web ACL that Firewall Manager retrofits has the name that the customer account specified at creation. A web ACL name can't be changed after creation. |

A web ACL name can't be changed after creation. Note If a resource configured with advanced automatic application layer DDoS mitigation comes into scope of a AWS WAF policy, Firewall Manager will be unable to associate the web ACL created by the AWS WAF policy to the resource. Logging for an AWS WAF policy You can enable centralized logging for your AWS WAF policies to get detailed information about traffic that's analyzed by your web ACL within your organization. AWS Firewall Manager supports this option for AWS WAFV2, not for AWS WAF Classic. The information in the logs includes the time that AWS WAF received the request from your protected AWS resource, detailed information about the request, and the action for the rule that AWS WAF policies 1082 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide each request matched from all in-scope accounts. For information about AWS WAF logging, see Logging AWS WAF web ACL traffic in the AWS WAF Developer Guide. You can send your logs to an Amazon Data Firehose data stream or Amazon Simple Storage Service (S3) bucket. Each destination type requires some additional configuration in order for Firewall Manager to be able to manage the AWS WAF logging across your in-scope resources and accounts. The sections that follow provide details. If the policy has web ACL retrofitting enabled, Firewall Manager doesn't override any logging configuration that's in place in existing web ACLs. For information about retrofitting, see the web ACL source configuration information at Web ACL management for AWS WAF policies. Note Only modify or disable logging for Firewall Manager policies through the Firewall Manager interface. If you use AWS WAF to update or delete the logging configuration of a web ACL that's managed by Firewall Manager, Firewall Manager won't detect the change automatically. If you have used AWS WAF, you can manually prompt an update to the Firewall Manager AWS WAF policy by re-evaluating the policy's rule in AWS Config. To do this, in the AWS Config console, locate the AWS Config rule for the Firewall Manager policy and select the re-evaluate action. Topics • Logging destinations • Enabling logging for an AWS WAF policy in Firewall Manager • Disabling logging for an AWS WAF policy in Firewall Manager Logging destinations This section describes the logging destinations that you can choose to send your AWS WAF policy logs. Each section provides guidance for configuring logging for the destination type and information about any behavior that's specific to the destination type. After you've configured your logging destination, you can provide its specifications to your Firewall Manager AWS WAF policy to start logging to it. Firewall Manager doesn't have visibility into log failures after creating the logging configuration. It's your responsibility to verify that log delivery is working as you intended. AWS WAF policies 1083 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Firewall Manager doesn't modify any existing logging configurations in your organization's member accounts. Topics • Amazon Data Firehose data streams • Amazon Simple Storage Service buckets Amazon Data Firehose data streams This topic provides information for sending your web ACL traffic logs to an Amazon Data Firehose data stream. When you enable Amazon Data Firehose logging, Firewall Manager sends logs from your policy's web ACLs to an Amazon Data Firehose where you've configured a storage destination. After you enable logging, AWS WAF delivers logs for each configured web ACL, through the HTTPS endpoint of Kinesis Data Firehose to the configured storage destination. Before you use it, test your delivery stream to be sure that it has enough throughput to accommodate your organization's logs. For more information about how to create an Amazon Kinesis Data Firehose and review the stored logs, see What Is Amazon Data Firehose?

AWS WAF policies 1084 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • You are charged for the web ACL according to the AWS WAF pricing guidelines. For more information, see AWS WAF Pricing. • Firewall Manager deletes the web ACL when you delete the policy. For information about service-linked roles and the iam:CreateServiceLinkedRole permission, see Using service-linked roles for AWS WAF. For more information about creating your delivery stream, see Creating an Amazon Data Firehose Delivery Stream. Amazon Simple Storage Service buckets This topic provides information for sending your web ACL traffic logs to an Amazon S3 bucket. The bucket that you choose as your logging destination must be owned by a Firewall Manager administrator account. For information about the requirements for creating your Amazon S3 bucket for logging and bucket naming requirements, see Amazon Simple Storage Service in the AWS WAF Developer Guide. Eventual consistency When you make change to AWS WAF policies configured with an Amazon S3 logging destination, Firewall Manager updates the bucket policy to add the permissions necessary for logging. When doing so, Firewall Manager follows the last-writer-wins semantics and data consistency models that Amazon Simple Storage Service follows. If you concurrently make multiple policy updates to a Amazon S3 destination in the Firewall Manager console or through the PutPolicy API, some permissions may not be saved. For more information about the Amazon S3 data consistency model, see Amazon S3 data consistency model in the Amazon Simple Storage Service User Guide. Permissions to publish logs to an Amazon S3 bucket Configuring web ACL traffic logging for an Amazon S3 bucket in an AWS WAF policy requires the following permissions settings. Firewall Manager automatically attaches these permissions to your Amazon S3 bucket when you configure Amazon S3 as your logging destination to give the service permission to publish logs to the bucket. If you want to manage finer-grained access to your logging and Firewall Manager resources, you can set these permissions yourself. For information about managing permissions, see Access management for AWS resources in the IAM User Guide. For information about the AWS WAF managed policies, see AWS managed policies for AWS WAF. { AWS WAF policies 1085 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide "Version": "2012-10-17", "Id": "AWSLogDeliveryForFirewallManager", "Statement": [ { "Sid": "AWSLogDeliveryAclCheckFMS", "Effect": "Allow", "Principal": { "Service": "delivery.logs.amazonaws.com" }, "Action": "s3:GetBucketAcl", "Resource": "arn:aws:s3:::aws-waf-logs-LOGGING-BUCKET-SUFFIX" }, { "Sid": "AWSLogDeliveryWriteFMS", "Effect": "Allow", "Principal": { "Service": "delivery.logs.amazonaws.com" }, "Action": "s3:PutObject", "Resource": "arn:aws:s3:::aws-waf-logs-LOGGING-BUCKET-SUFFIX/policy-id/ AWSLogs/*", "Condition": { "StringEquals": { "s3:x-amz-acl": "bucket-owner-full-control" } } } ] } To prevent the cross-service confused deputy problem, you can add the aws:SourceArn and aws:SourceAccount global condition context keys to your bucket's policy. To add these keys, you can either modify the policy that Firewall Manager creates for you when you configure the logging destination, or if you want fine grained control, you can create your own policy. If you add these conditions to your logging destination policy, Firewall Manager won't validate or monitor the confused deputy protections. For general information about the confused deputy problem, see The confused deputy problem in the IAM User Guide. When you add the sourceAccount add sourceArn properties it'll increase the bucket policy size.

Enabling logging for an AWS WAF policy in Firewall Manager The following procedure describes how to enable logging for an AWS WAF policy in the Firewall Manager console. To enable logging for an AWS WAF policy 1. Before you can enable logging, you must configure your logging destination resources as the following: • Amazon Kinesis Data Streams - Create an Amazon Data Firehose using your Firewall Manager administrator account. Use a name starting with the prefix aws-waf-logs-. For example, aws-waf-logs-firewall-manager-central. Create the data firehose with a PUT source and in the Region that you are operating. If you are capturing logs for Amazon CloudFront, create the firehose in US East (N. Virginia). Before you use it, test your delivery stream to be sure that it has enough throughput to accommodate your organization's logs. For more information, see Creating an Amazon Data Firehose delivery stream. • Amazon Simple Storage Service buckets - Create an Amazon S3 bucket according to the guidelines in the Amazon Simple Storage Service topic in the AWS WAF Developer Guide. You must also configure your Amazon S3 bucket with the permissions listed in Permissions to publish logs to an Amazon S3 bucket . 2. Sign in to the AWS Management Console using your Firewall Manager administrator account, and then open the Firewall Manager console at https://console.aws.amazon.com/wafv2/ fmsv2. For information about setting up a Firewall Manager administrator account, see AWS Firewall Manager prerequisites. Note For information about setting up a Firewall Manager administrator account, see AWS Firewall Manager prerequisites. 3. In the navigation pane, choose Security Policies. 4. Choose the AWS WAF policy that you want to enable logging for. For more information about AWS WAF logging, see Logging AWS WAF web ACL traffic. AWS WAF policies 1089 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide 5. On the Policy details tab, in the Policy rules section, choose Edit. 6. 7. 8. For Logging configuration, choose Enable logging to turn on logging. Logging provides detailed information about traffic that is analyzed by your web ACL. Choose the Logging destination, and then choose the logging destination that you configured. You must choose a logging destination whose name begins with aws-waf-logs-. For information about configuring an AWS WAF logging destination, see Using AWS WAF policies with Firewall Manager. (Optional) If you don't want certain fields and their values included in the logs, redact those fields. Choose the field to redact, and then choose Add. Repeat as necessary to redact additional fields. The redacted fields appear as REDACTED in the logs. For example, if you redact the URI field, the URI field in the logs will be REDACTED. (Optional) If you don't want to send all requests to the logs, add your filtering criteria and behavior. Under Filter logs, for each filter that you want to apply, choose Add filter, then choose your filtering criteria and specify whether you want to keep or drop requests that match the criteria. When you finish adding filters, if needed, modify the Default logging behavior. For more information, see Finding your web ACL records in the AWS WAF Developer Guide. 9. Choose Next. 10.

AWS WAF policies 1090 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide 2. In the navigation pane, choose Security Policies. 3. Choose the AWS WAF policy that you want to disable logging for. 4. On the Policy details tab, in the Policy rules section, choose Edit. 5. For Logging configuration status, choose Disabled. 6. Choose Next. 7. Review your settings, then choose Save to save your changes to the policy. Note Only modify or disable logging for Firewall Manager policies through the Firewall Manager interface. If you use AWS WAF to update or delete the logging configuration of a web ACL that's managed by Firewall Manager, Firewall Manager won't detect the change automatically. If you have used AWS WAF, you can manually prompt an update to the Firewall Manager AWS WAF policy by re-evaluating the policy's rule in AWS Config. To do this, in the AWS Config console, locate the AWS Config rule for the Firewall Manager policy and select the re-evaluate action. Using AWS Shield Advanced policies in Firewall Manager This page explains how to use AWS Shield policies with Firewall Manager. In a Firewall Manager AWS Shield policy, you choose the resources that you want to protect. When you apply the policy with auto remediation enabled, for each in-scope resource that's not already associated with a AWS WAF web ACL, Firewall Manager associates an empty AWS WAF web ACL. The empty web ACL is used for Shield monitoring purposes. If you then associate any other web ACL to the resource, Firewall Manager removes the empty web ACL association. Note When a resource that's in scope of an AWS WAF policy comes into the scope of a Shield Advanced policy configured with automatic application layer DDoS mitigation, Firewall Manager applies the Shield Advanced protection only after associating the web ACL created by the AWS WAF policy. AWS Shield Advanced policies 1091 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide How AWS Firewall Manager manages unassociated web ACLs in Shield policies You can configure whether Firewall Manager manages unassociated web ACLs for you through the Manage unassociated web ACLs setting in your policy, or the optimizeUnassociatedWebACLs setting in the SecurityServicePolicyData data type in the API. If you enable management of unassociated web ACLs in your policy, Firewall Manager creates web ACLs in the accounts within policy scope only if the web ACLs will be used by at least one resource. If at any time an account comes into policy scope, Firewall Manager automatically creates a web ACL in the account if at least one resource will use the web ACL. When you enable management of unassociated web ACLs, Firewall Manager performs a one-time cleanup of unassociated web ACLs in your account. The cleanup process can take several hours. If a resource leaves policy scope after Firewall Manager creates a web ACL, Firewall Manager doesn't disassociate the resource from the web ACL. If you want Firewall Manager to clean up the web ACL, you must first manually disassociate the resources from the web ACL, and then enable the manage unassociated web ACLs option in your policy. If you don't enable this option, Firewall Manager doesn't manage unassociated web ACLs, and Firewall Manager automatically creates a web ACL in each account that's within policy scope. How AWS Firewall Manager manages scope changes in Shield policies Accounts and resources can go out of scope of an AWS Firewall Manager Shield Advanced policy due to a number of changes, such as changes to policy scope settings, changes to the tags on a resource, and the removal of an account from |
waf-dg-412 | waf-dg.pdf | 412 | disassociate the resources from the web ACL, and then enable the manage unassociated web ACLs option in your policy. If you don't enable this option, Firewall Manager doesn't manage unassociated web ACLs, and Firewall Manager automatically creates a web ACL in each account that's within policy scope. How AWS Firewall Manager manages scope changes in Shield policies Accounts and resources can go out of scope of an AWS Firewall Manager Shield Advanced policy due to a number of changes, such as changes to policy scope settings, changes to the tags on a resource, and the removal of an account from an organization. For general information about policy scope settings, see Using the AWS Firewall Manager policy scope. With an AWS Firewall Manager Shield Advanced policy, if an account or resource goes out of scope, Firewall Manager stops monitoring the account or resource. If an account goes out of scope by being removed from the organization, it will continue to be subscribed to Shield Advanced. Because the account is no longer part of the consolidated billing family, the account will incur a prorated Shield Advanced subscription fee. On the other hand, an account that goes out of scope but remains in the organization doesn't incur additional fees. If a resource goes out of scope, it continues to be protected by Shield Advanced and continues to incur Shield Advanced data transfer charges. AWS Shield Advanced policies 1092 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Using Automatic application layer DDoS mitigation with Firewall Manager Shield Advanced policies This page explains how Automatic application layer DDoS mitigation works with Firewall Manager. When you apply a Shield Advanced policy to Amazon CloudFront distributions or Application Load Balancers, you have the option of configuring Shield Advanced automatic application layer DDoS mitigation in the policy. For information about Shield Advanced automatic mitigation, see Automating application layer DDoS mitigation with Shield Advanced . Shield Advanced automatic application layer DDoS mitigation has the following requirements: • Automatic application layer DDoS mitigation works only with Amazon CloudFront distributions and Application Load Balancers. If applying your Shield Advanced policy to Amazon CloudFront distributions, you can choose this option for Shield Advanced policies that you create for the Global Region. If applying protections to Application Load Balancers, you can apply the policy to any Region that Firewall Manager supports. • Automatic application layer DDoS mitigation works only with web ACLs that were created using the latest version of AWS WAF (v2). Because of this, if you have a policy that uses AWS WAF Classic web ACLs, you need to either replace the policy with a new policy, which will automatically use the latest version of AWS WAF, or have Firewall Manager create new version web ACLs for your existing policy and switch over to using them. For more information about the options, see Replace AWS WAF Classic web ACLs with latest version web ACLs. Automatic mitigation configuration The automatic application layer DDoS mitigation option for Firewall Manager Shield Advanced policies applies Shield Advanced automatic mitigation functionality to your policy's in-scope accounts and resources. For detailed information about this Shield Advanced feature, see Automating application layer DDoS mitigation with Shield Advanced . AWS Shield Advanced policies 1093 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide You can choose to have Firewall Manager enable or disable automatic mitigation for the CloudFront distributions or Application Load Balancers that are in scope of the policy, or you can choose to have the policy ignore Shield Advanced automatic mitigation settings: • Enable – If you choose to enable automatic mitigation, you also specify whether mitigating Shield Advanced rules should count or block matching web requests. Firewall Manager will mark in-scope resources as noncompliant if they either don't have automatic mitigation enabled, or are using a rule action that doesn't match the one you specify for the policy. If you configure the policy for automatic remediation, Firewall Manager updates noncompliant resources as needed. • Disable – If you choose to disable automatic mitigation, Firewall Manager will mark in-scope resources as noncompliant if they have automatic mitigation enabled. If you configure the policy for automatic remediation, Firewall Manager updates noncompliant resources as needed. • Ignore – If you choose to ignore automatic mitigation, Firewall Manager won't consider any of the automatic mitigation settings in your Shield policy when it performs remediation activities for the policy. This setting allows you to control automatic mitigation through Shield Advanced, without having those settings overwritten by Firewall Manager. This setting doesn't apply to any Classic Load Balancers or Elastic IPs resources manged through Shield Advanced, because Shield Advanced doesn't currently support L7 automatic mitigation for those resources. Replace AWS WAF Classic web ACLs with latest version web ACLs Automatic application layer DDoS mitigation works only with |
waf-dg-413 | waf-dg.pdf | 413 | needed. • Ignore – If you choose to ignore automatic mitigation, Firewall Manager won't consider any of the automatic mitigation settings in your Shield policy when it performs remediation activities for the policy. This setting allows you to control automatic mitigation through Shield Advanced, without having those settings overwritten by Firewall Manager. This setting doesn't apply to any Classic Load Balancers or Elastic IPs resources manged through Shield Advanced, because Shield Advanced doesn't currently support L7 automatic mitigation for those resources. Replace AWS WAF Classic web ACLs with latest version web ACLs Automatic application layer DDoS mitigation works only with web ACLs that were created using the latest version of AWS WAF (v2). To determine the web ACL version for your Shield Advanced policy, see Determining the version of AWS WAF that's used by a Shield Advanced policy. If you want to use automatic mitigation in your Shield Advanced policy, and your policy currently uses AWS WAF Classic web ACLs, you can either create a new Shield Advanced policy to replace your current one, or you can use the options described in this section to replace earlier version web ACLs with new (v2) web ACLs inside your current Shield Advanced policy. New policies always create web ACLs using the latest version of AWS WAF. If you replace the entire policy, when you delete it, you can have Firewall Manager delete all of the earlier version web ACLs as well. The rest of this section describes your options for replacing the web ACLs inside your existing policy. When you modify an existing Shield Advanced policy for Amazon CloudFront resources, Firewall Manager can automatically create a new empty AWS WAF (v2) web ACL for the policy, in any in- AWS Shield Advanced policies 1094 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide scope account that doesn't already have a v2 web ACL. When Firewall Manager creates a new web ACL, if the policy already has an AWS WAF Classic web ACL in the same account, Firewall Manager configures the new version web ACL with the same default action setting as the existing web ACL. If there is no existing AWS WAF Classic web ACL, Firewall Manager sets the default action to Allow in the new web ACL. After Firewall Manager creates a new web ACL, you can customize it as needed through the AWS WAF console. When you choose any of the following policy configuration options, Firewall Manager creates new (v2) web ACLs for in-scope accounts that don't already have them: • When you enable or disable automatic application layer DDoS mitigation. This choice alone only causes Firewall Manager to create the new web ACLs, and not to replace any existing AWS WAF Classic web ACL associations on the policy's in-scope resources. • When you choose the policy action of automatic remediation and you choose the option to replace AWS WAF Classic web ACLs with AWS WAF (v2) web ACLs. You can choose to replace earlier version web ACLs regardless of your configuration choices for automatic application layer DDoS mitigation. When you choose the replacement option, Firewall Manager creates the new version web ACLs as needed and then does the following for the policy's in-scope resources: • If a resource is associated with a web ACL from any other active Firewall Manager policy, Firewall Manager leaves the association alone. • For any other case, Firewall Manager removes any association with an AWS WAF Classic web ACL and associates the resource with the policy's AWS WAF (v2) web ACL. You can choose to have Firewall Manager replace the earlier version web ACLs with the new version web ACLs when you want to. If you've previously customized the policy's AWS WAF Classic web ACLs, you can update new version web ACLs to comparable settings before you choose to have Firewall Manager perform the replacement step. You can access either version of web ACL for a policy through the same-version console for AWS WAF or AWS WAF Classic. Firewall Manager doesn't delete any replaced AWS WAF Classic web ACLs until you delete the policy itself. After the AWS WAF Classic web ACLs are no longer used by the policy, you can delete them if you want to. AWS Shield Advanced policies 1095 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Determining the version of AWS WAF that's used by a Shield Advanced policy This page explains how to determine which version of AWS WAF web ACL your Shield Advanced policy uses. You can determine which version of AWS WAF your Firewall Manager Shield Advanced policy uses by looking at the parameter keys in the policy's AWS Config service-linked rule. If the AWS WAF version that's in use is the latest, the parameter keys include policyId and webAclArn. If it's |
waf-dg-414 | waf-dg.pdf | 414 | them if you want to. AWS Shield Advanced policies 1095 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Determining the version of AWS WAF that's used by a Shield Advanced policy This page explains how to determine which version of AWS WAF web ACL your Shield Advanced policy uses. You can determine which version of AWS WAF your Firewall Manager Shield Advanced policy uses by looking at the parameter keys in the policy's AWS Config service-linked rule. If the AWS WAF version that's in use is the latest, the parameter keys include policyId and webAclArn. If it's the earlier version, AWS WAF Classic, the parameter keys include webAclId and resourceTypes. The AWS Config rule only lists keys for the web ACLs that the policy is currently using with in-scope resources. To determine which version of AWS WAF your Firewall Manager Shield Advanced policy uses 1. Retrieve the policy ID for the Shield Advanced policy: a. Sign in to the AWS Management Console using your Firewall Manager administrator account, and then open the Firewall Manager console at https:// console.aws.amazon.com/wafv2/fmsv2. For information about setting up a Firewall Manager administrator account, see AWS Firewall Manager prerequisites. b. c. d. In the navigation pane, choose Security Policies. Choose the Region for the policy. For CloudFront distributions, this is Global. Find the policy that you want and copy the value of its Policy ID. Example policy ID: 1111111-2222-3333-4444-a55aa5aaa555. 2. Create the policy's AWS Config rule name by appending the policy ID to the string FMManagedShieldConfigRule. Example AWS Config rule name: FMManagedShieldConfigRule1111111-2222-3333-4444-a55aa5aaa555. 3. Search the parameters for the associated AWS Config rule for keys named policyId and webAclArn: a. Open the AWS Config console at https://console.aws.amazon.com/config/. b. c. In the navigation pane, choose Rules. Find your Firewall Manager policy's AWS Config rule name in the list and select it. The rule's page opens. AWS Shield Advanced policies 1096 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide d. Under Rule details, in the Parameters section, look at the keys. If you find keys named policyId and webAclArn, the policy uses web ACLs that were created using the latest version of AWS WAF. If you find keys named webAclId and resourceTypes, the policy uses web ACLs that were created using the earlier version, AWS WAF Classic. Using security group policies in Firewall Manager to manage Amazon VPC security groups This page explains how to use AWS Firewall Manager security group policies to manage Amazon Virtual Private Cloud security groups for your organization in AWS Organizations. You can apply centrally controlled security group policies to your entire organization or to a select subset of your accounts and resources. You can also monitor and manage the security group policies that are in use in your organization, with auditing and usage security group policies. Firewall Manager continuously maintains your policies and applies them to accounts and resources as they are added or updated across your organization. For information about AWS Organizations, see AWS Organizations User Guide. For information about Amazon Virtual Private Cloud security groups, see Security Groups for Your VPC in the Amazon VPC User Guide. You can use Firewall Manager security group policies to do the following across your AWS organization: • Apply common security groups to specified accounts and resources. • Audit security group rules, to locate and remediate noncompliant rules. • Audit usage of security groups, to clean up unused and redundant security groups. This section covers how Firewall Manager security groups policies work and provides guidance for using them. For procedures to create security group policies, see Creating an AWS Firewall Manager policy. Best practices for security group policies This section lists recommendations for managing security groups using AWS Firewall Manager. Exclude the Firewall Manager administrator account Security group policies 1097 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide When you set the policy scope, exclude the Firewall Manager administrator account. When you create a usage audit security group policy through the console, this is the default option. Start with automatic remediation disabled For content or usage audit security group policies, start with automatic remediation disabled. Review the policy details information to determine the effects that automatic remediation would have. When you are satisfied that the changes are what you want, edit the policy to enable automatic remediation. Avoid conflicts if you also use outside sources to manage security groups If you use a tool or service other than Firewall Manager to manage security groups, take care to avoid conflicts between your settings in Firewall Manager and the settings in your outside source. If you use automatic remediation and your settings conflict, you can create a cycle of conflicting remediation that consumes resources on both sides. For example, say you configure another service to maintain a security |
waf-dg-415 | waf-dg.pdf | 415 | remediation would have. When you are satisfied that the changes are what you want, edit the policy to enable automatic remediation. Avoid conflicts if you also use outside sources to manage security groups If you use a tool or service other than Firewall Manager to manage security groups, take care to avoid conflicts between your settings in Firewall Manager and the settings in your outside source. If you use automatic remediation and your settings conflict, you can create a cycle of conflicting remediation that consumes resources on both sides. For example, say you configure another service to maintain a security group for a set of AWS resources, and you configure a Firewall Manager policy to maintain a different security group for some or all of the same of resources. If you configure either side to disallow any other security group to be associated with the in-scope resources, that side will remove the security group association that's maintained by the other side. If both sides are configured in this way, you can end up with a cycle of conflicting disassociations and associations. Additionally, say that you create a Firewall Manager audit policy to enforce a security group configuration that conflicts with the security group configuration from the other service. Remediation applied by the Firewall Manager audit policy can update or delete that security group, putting it out of compliance for the other service. If the other service is configured to monitor and automatically remediate any problems it finds, it will recreate or update the security group, putting it again out of compliance with the Firewall Manager audit policy. If the Firewall Manager audit policy is configured with automatic remediation, it will again update or delete the outside security group, and so on. To avoid conflicts like these, create configurations that are mutually exclusive, between Firewall Manager and any outside sources. You can use tagging to exclude outside security groups from automatic remediation by your Firewall Manager policies. To do this, add one or more tags to the security groups or other resources that are managed by the outside source. Then, when you define the Firewall Manager Security group policies 1098 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide policy scope, in your resources specification, exclude resources that have the tag or tags that you've added. Similarly, in your outside tool or service, exclude the security groups that Firewall Manager manages from any management or auditing activities. Either don't import the Firewall Manager resources or use Firewall Manager-specific tagging to exclude them from outside management. Best practices for usage audit security group policies Follow these guidelines when you use usage audit security group policies. • Avoid making multiple changes to the association status of a security group in a short amount of time, such as within a 15-minute window. Doing so can cause Firewall Manager to miss some or all of the corresponding events. For example, don't quickly associate and disassociate a security group with an elastic network interface. Security group policy caveats and limitations This section lists the caveats and limitations for using Firewall Manager security group policies. Resource type: Amazon EC2 instance This section lists the caveats and limitations for protecting Amazon EC2 instances with Firewall Manager security group policies. • With security groups that protect Amazon EC2 elastic network interfaces (ENIs), changes to a security group aren't immediately visible to Firewall Manager. Firewall Manager usually detects changes within several hours, but detection can be delayed as much as six hours. • Firewall Manager doesn't support security groups for Amazon EC2 ENIs that were created by the Amazon Relational Database Service. • Firewall Manager doesn't support updating security groups for Amazon EC2 ENIs that were created using the Fargate service type. You can, however, update security groups for Amazon ECS ENIs with the Amazon EC2 service type. • Firewall Manager doesn't support updating security groups for requester-managed Amazon EC2 ENIs, because Firewall Manager doesn't have permission to modify them. • For common security group policies, these caveats concern the interaction between the number of elastic network interfaces (ENIs) that are attached to the EC2 instance and the policy option that specifies whether to remediate only EC2 instances with no added attachments or to Security group policies 1099 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide remediate all instances. Every EC2 instance has a default primary ENI, and you can attach more ENIs. In the API, the policy option setting for this choice is ApplyToAllEC2InstanceENIs. If an in-scope EC2 instance has additional ENIs attached and the policy is configured to include only EC2 instances with just the primary ENI, then Firewall Manager won't attempt any remediation for the EC2 instance. Additionally, If the instance goes out of policy scope, Firewall Manager doesn't attempt to disassociate |
waf-dg-416 | waf-dg.pdf | 416 | with no added attachments or to Security group policies 1099 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide remediate all instances. Every EC2 instance has a default primary ENI, and you can attach more ENIs. In the API, the policy option setting for this choice is ApplyToAllEC2InstanceENIs. If an in-scope EC2 instance has additional ENIs attached and the policy is configured to include only EC2 instances with just the primary ENI, then Firewall Manager won't attempt any remediation for the EC2 instance. Additionally, If the instance goes out of policy scope, Firewall Manager doesn't attempt to disassociate any security group associations that it might have established for the instance. For the following edge cases, during resource cleanup, Firewall Manager can leave replicated security group associations intact, regardless of the policy's resource cleanup specifications: • When an instance with additional ENIs was previously remediated by a policy that was configured to include all EC2 instances, and then either the instance went out of policy scope or the policy setting was changed to include only instances without additional ENIs. • When an instance with no additional ENIs was remediated by an policy that was configured to include only instances with no additional ENIs, then another ENI was attached to the instance, and then the instance went out of policy scope. Other caveats and limitations The following are miscellaneous caveats and limitations for Firewall Manager security group policies. • Firewall Manager security group policies do not support security groups shared through AWS RAM. • Updating Amazon ECS ENIs is possible only for Amazon ECS services that use the rolling update (Amazon ECS) deployment controller. For other Amazon ECS deployment controllers such as CODE_DEPLOY or external controllers, Firewall Manager currently can't update the ENIs. • Firewall Manager doesn't support updating security groups in ENIs for Network Load Balancers. • In common security group policies, if a shared VPC is later unshared with an account Firewall Manager won't delete the replica security groups in the account. • With usage audit security group policies, if you create multiple policies with a custom delay time setting that all have the same scope, the first policy with compliance findings will be the policy that reports the findings. Security group policies 1100 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Security group policy use cases You can use AWS Firewall Manager common security group policies to automate the host firewall configuration for communication between Amazon VPC instances. This section lists standard Amazon VPC architectures and describes how to secure each using Firewall Manager common security group policies. These security group policies can help you apply a unified set of rules to select resources in different accounts and avoid per-account configurations in Amazon Elastic Compute Cloud and Amazon VPC. With Firewall Manager common security group policies, you can tag just the EC2 elastic network interfaces that you need for communication with instances in another Amazon VPC. The other instances in the same Amazon VPC are then more secure and isolated. Use case: Monitoring and controlling requests to Application Load Balancers and Classic Load Balancers You can use a Firewall Manager common security group policy to define which requests your in- scope load balancers should serve. You can configure this through the Firewall Manager console. Only requests that comply with the security group's inbound rules can reach your load balancers, and the load balancers will only distribute requests that meet the outbound rules. Use case: Internet-accessible, public Amazon VPC You can use a Firewall Manager common security group policy to secure a public Amazon VPC, for example, to allow only inbound port 443. This is the same as only allowing inbound HTTPS traffic for a public VPC. You can tag public resources within the VPC (for example, as "PublicVPC"), and then set the Firewall Manager policy scope to only resources with that tag. Firewall Manager automatically applies the policy to those resources. Use case: Public and Private Amazon VPC instances You can use the same common security group policy for public resources as recommended in the prior use case for internet-accessible, public Amazon VPC instances. You can use a second common security group policy to limit communication between the public resources and the private ones. Tag the resources in the public and private Amazon VPC instances with something like "PublicPrivate" to apply the second policy to them. You can use a third policy to define the allowed communication between the private resources and other corporation or private Amazon VPC instances. For this policy, you can use another identifying tag on the private resources. Use case: Hub and spoke Amazon VPC instances Security group policies 1101 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide You can use a common security group policy to |
waf-dg-417 | waf-dg.pdf | 417 | limit communication between the public resources and the private ones. Tag the resources in the public and private Amazon VPC instances with something like "PublicPrivate" to apply the second policy to them. You can use a third policy to define the allowed communication between the private resources and other corporation or private Amazon VPC instances. For this policy, you can use another identifying tag on the private resources. Use case: Hub and spoke Amazon VPC instances Security group policies 1101 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide You can use a common security group policy to define communications between the hub Amazon VPC instance and spoke Amazon VPC instances. You can use a second policy to define communication from each spoke Amazon VPC instance to the hub Amazon VPC instance. Use case: Default network interface for Amazon EC2 instances You can use a common security group policy to allow only standard communications, for example internal SSH and patch/OS update services, and to disallow other insecure communication. Use case: Identify resources with open permissions You can use an audit security group policy to identify all resources within your organization that have permission to communicate with public IP addresses or that have IP addresses that belong to third-party vendors. Using common security group policies with Firewall Manager This page explains how Firewall Manager common security group policies work. With a common security group policy, Firewall Manager provides a centrally controlled association of security groups to accounts and resources across your organization. You specify where and how to apply the policy in your organization. You can apply common security group policies to the following resource types: • Amazon Elastic Compute Cloud (Amazon EC2) instance • Elastic Network Interface • Application Load Balancer • Classic Load Balancer For guidance on creating a common security group policy using the console, see Creating a common security group policy. Shared VPCs In the policy scope settings for a common security group policy, you can choose to include shared VPCs. This choice includes VPCs that are owned by another account and shared with an in-scope account. VPCs that in-scope accounts own are always included. For information about shared VPCs, see Working with shared VPCs in the Amazon VPC User Guide. Security group policies 1102 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide The following caveats apply to including shared VPCs. These are in addition to the general caveats for security group policies at Security group policy caveats and limitations. • Firewall Manager replicates the primary security group into the VPCs for each in-scope account. For a shared VPC, Firewall Manager replicates the primary security group once for each in-scope account that the VPC is shared with. This can result in multiple replicas in a single shared VPC. • When you create a new shared VPC, you won’t see it represented in the Firewall Manager security group policy details until after you create at least one resource in the VPC that's within the scope of the policy. • When you disable shared VPCs in a policy that had shared VPCs enabled, in the shared VPCs, Firewall Manager deletes the replica security groups that aren’t associated with any resources. Firewall Manager leaves the remaining replica security groups in place, but stops managing them. Removal of these remaining security groups requires manual management in each shared VPC instance. Primary security groups For each common security group policy, you provide AWS Firewall Manager with one or more primary security groups: • Primary security groups must be created by the Firewall Manager administrator account and can reside in any Amazon VPC instance in the account. • You manage your primary security groups through Amazon Virtual Private Cloud (Amazon VPC) or Amazon Elastic Compute Cloud (Amazon EC2). For information, see Working with Security Groups in the Amazon VPC User Guide. • You can name one or more security groups as primaries for a Firewall Manager security group policy. By default, the number of security groups allowed in a policy is one, but you can submit a request to increase it. For information, see AWS Firewall Manager quotas. Policy rules settings You can choose one or more of the following change control behaviors for the security groups and resources of your common security group policy: • Identify and report on any changes made by local users to replica security groups. • Disassociate any other security groups from the AWS resources that are within the policy scope. • Distribute tags from the primary group to the replica security groups. Security group policies 1103 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Important Firewall Manager won't distribute system tags added by AWS services into the replica security groups. System tags begin with the aws: prefix. Additionally, Firewall |
waf-dg-418 | waf-dg.pdf | 418 | the following change control behaviors for the security groups and resources of your common security group policy: • Identify and report on any changes made by local users to replica security groups. • Disassociate any other security groups from the AWS resources that are within the policy scope. • Distribute tags from the primary group to the replica security groups. Security group policies 1103 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Important Firewall Manager won't distribute system tags added by AWS services into the replica security groups. System tags begin with the aws: prefix. Additionally, Firewall Manager won't update the tags of existing security groups or create new security groups if the policy has tags that conflict with the organization's tag policy. For information about tag policies, see Tag policies in the AWS Organizations User Guide. • Distribute security group references from the primary group to the replica security groups. This enables you to easily establish common security group referencing rules across all in-scope resources to instances associated with the specified security group's VPC. When you enable this option, Firewall Manager only propagates the security group references if the security groups reference peer security groups in Amazon Virtual Private Cloud. If the replica security groups don't correctly reference the peer security group, Firewall Manager marks these replicated security groups as non-compliant. For information about how to reference peer security groups in Amazon VPC, see Update your security groups to reference peer security groups in the Amazon VPC Peering Guide. If you don't enable this option, Firewall Manager doesn't propagate security group references to the replica security groups. For information about VPC peering in Amazon VPC, see the Amazon VPC Peering Guide. Policy creation and management When you create your common security group policy, Firewall Manager replicates the primary security groups to every Amazon VPC instance within the policy scope, and associates the replicated security groups to accounts and resources that are in scope of the policy. When you modify a primary security group, Firewall Manager propagates the change to the replicas. When you delete a common security group policy, you can choose whether to clean up the resources created by the policy. For Firewall Manager common security groups, these resources are the replica security groups. Choose the cleanup option unless you want to manually manage each individual replica after the policy is deleted. For most situations, choosing the cleanup option is the simplest approach. How replicas are managed Security group policies 1104 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide The replica security groups in the Amazon VPC instances are managed like other Amazon VPC security groups. For information, see Security Groups for Your VPC in the Amazon VPC User Guide. Using content audit security group policies with Firewall Manager This page explains how Firewall Manager content audit security group policies work. Use AWS Firewall Manager content audit security group policies to audit and apply policy actions to the rules that are in use in your organization's security groups. Content audit security group policies apply to all customer-created security groups in use in your AWS organization, according to the scope that you define in the policy. For guidance on creating a content audit security group policy using the console, see Creating a content audit security group policy. Policy scope resource type You can apply content audit security group policies to the following resource types: • Amazon Elastic Compute Cloud (Amazon EC2) instance • Elastic Network Interface • Amazon VPC security group Security groups are considered in scope of the policy if they explicitly are in scope or if they're associated with resources that are in scope. Policy rule options You can use either managed policy rules or custom policy rules for each content audit policy, but not both. • Managed policy rules – In a policy with managed rules, you can use application and protocol lists to control which rules that Firewall Manager audits and either marks as compliant or non- compliant. You can use lists that are managed by Firewall Manager. You can also create and use your own application and protocol lists. For information about these types of lists and your management options for custom lists, see Using Firewall Manager managed lists. • Custom policy rules – In a policy with custom policy rules, you specify an existing security group as the audit security group for your policy. You can use the audit security group rules as a template that defines the rules that Firewall Manager audits and either marks as compliant or non-compliant. Security group policies 1105 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Audit security groups You must create audit security groups using your Firewall Manager administrator account, before you can use them in your |

You can use the audit security group rules as a template that defines the rules that Firewall Manager audits and either marks as compliant or non-compliant. Security group policies 1105 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Audit security groups You must create audit security groups using your Firewall Manager administrator account, before you can use them in your policy. You can manage security groups through Amazon Virtual Private Cloud (Amazon VPC) or Amazon Elastic Compute Cloud (Amazon EC2). For information, see Working with Security Groups in the Amazon VPC User Guide. A security group that you use for a content audit security group policy is used by Firewall Manager only as a comparison reference for the security groups that are in scope of the policy. Firewall Manager doesn't associate it with any resources in your organization. The way that you define the rules in the audit security group depends on your choices in the policy rules settings: • Managed policy rules – For managed policy rules settings, you use an audit security group to override other settings in the policy, to explicitly allow or deny rules that otherwise might have another compliance outcome. • If you choose to always allow the rules that are defined in the audit security group, any rule that matches one that's defined in the audit security group is considered compliant with the policy, regardless of the other policy settings. • If you choose to always deny the rules that are defined in the audit security group, any rule that matches one that's defined in the audit security group is considered noncompliant with the policy, regardless of the other policy settings. • Custom policy rules – For custom policy rules settings, the audit security group provides the example of what is acceptable or not acceptable in the in-scope security group rules: • If you choose to allow the use of the rules, all in-scope security groups must only have rules that are within the allowed range of the policy's audit security group rules. In this case, the policy's security group rules provide the example of what's acceptable to do. • If you choose to deny the use of the rules, all in-scope security groups must only have rules that are not within the allowed range of the policy's audit security group rules. In this case, the policy's security group provides the example of what's not acceptable to do. Policy creation and management When you create an audit security group policy, you must have automatic remediation disabled. The recommended practice is to review the effects of policy creation before enabling automatic remediation. After you review the expected effects, you can edit the policy and enable automatic Security group policies 1106 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide remediation. When automatic remediation is enabled, Firewall Manager updates or removes rules that are noncompliant in in-scope security groups. Security groups affected by an audit security group policy All security groups in your organization that are customer-created are eligible to be in scope of an audit security group policy. Replica security groups are not customer-created and so aren't eligible to be directly in scope of an audit security group policy. However, they can be updated as a result of the policy's automatic remediation activities. A common security group policy's primary security group is customer- created and can be in scope of an audit security group policy. If an audit security group policy makes changes to a primary security group, Firewall Manager automatically propagates those changes to the replicas. Caveats and limitations for content audit security group policies You cannot reference peer security groups in a content audit security group policy. For information on other considerations across all Firewall Manager security groups, see Security group policy caveats and limitations. Using usage audit security group policies with Firewall Manager This page explains how Firewall Manager usage audit security group policies work. Use AWS Firewall Manager usage audit security group policies to monitor your organization for unused and redundant security groups and optionally perform cleanup. When you enable automatic remediation for this policy, Firewall Manager does the following: 1. Consolidates redundant security groups, if you've chosen that option. 2. Removes unused security groups, if you've chosen that option. You can apply usage audit security group policies to the following resource type: • Amazon VPC security group For guidance on creating a usage audit security group policy using the console, see Creating a usage audit security group policy.

When you enable automatic remediation for this policy, Firewall Manager does the following: 1. Consolidates redundant security groups, if you've chosen that option. 2. Removes unused security groups, if you've chosen that option. You can apply usage audit security group policies to the following resource type: • Amazon VPC security group For guidance on creating a usage audit security group policy using the console, see Creating a usage audit security group policy. Security group policies 1107 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide How Firewall Manager detects and remediates redundant security groups For security groups to be considered redundant, they must have exactly the same rules set and be in the same Amazon VPC instance. To remediate a redundant security group set, Firewall Manager selects one of the security groups in the set to keep, and then associates it to all resources that are associated with the other security groups in the set. Firewall Manager then disassociates the other security groups from the resources they were associated with, which renders them unused. Note If you have also chosen to remove unused security groups, Firewall Manager does that next. This can result in the removal of the security groups that are in the redundant set. How Firewall Manager detects and remediates unused security groups Firewall Manager considers a security group to be unused if both of the following are true: • The security group is not used by any Amazon EC2 instance or Amazon EC2 elastic network interface. • Firewall Manager hasn't received a configuration item for it within the number of minutes specified in the policy rule time period. The policy rule time period has a default setting of zero minutes, but you can increase the time up to 365 days (525,600 minutes), to give yourself time to associate new security groups with resources. Important If you specify a number of minutes other than the default value of zero, you must enable indirect relationships in AWS Config. Otherwise, your usage audit security group policies will not work as intended. For information about indirect relationships in AWS Config, see Indirect Relationships in AWS Config in the AWS Config Developer Guide. Firewall Manager remediates unused security groups by deleting them from your account according to your rules settings, if possible. If Firewall Manager is unable to delete a security group, it marks Security group policies 1108 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide it as noncompliant with the policy. Firewall Manager can't delete a security group that's referenced by another security group. The timing of the remediation varies according to whether you use the default time period setting or a custom setting: • Time period set to zero, the default – With this setting, a security group is considered unused as soon as it's not being used by an Amazon EC2 instance or elastic network interface. For this zero time period setting, Firewall Manager remediates the security group immediately. • Time period greater than zero – With this setting, a security group is considered unused when it's not being used by an Amazon EC2 instance or elastic network interface and Firewall Manager hasn't received a configuration item for it within the specified number of minutes. For the non-zero time period setting, Firewall Manager remediates the security group after it's remained in the unused state for 24 hours. Default account specification When you create a usage audit security group policy through the console, Firewall Manager automatically chooses Exclude the specified accounts and include all others. The service then puts the Firewall Manager administrator account in the list to exclude. This is the recommended approach, and allows you to manually manage the security groups that belong to the Firewall Manager administrator account. Using Amazon VPC network access control list (ACL) policies with Firewall Manager This section covers how AWS Firewall Manager network ACL policies work and provides guidance for using them. For guidance creating a network ACL policy using the console, see Creating a network ACL policy. For information about Amazon VPC network access control lists (ACLs), see Control traffic to subnets using network ACLs in the Amazon VPC User Guide. You can use Firewall Manager network ACL policies to manage Amazon Virtual Private Cloud (Amazon VPC) network access control lists (ACLs) for your organization in AWS Organizations. You define the policy's network ACL rule settings and the accounts and subnets where you want the settings enforced. Firewall Manager continuously applies your policy settings to accounts Network ACL policies 1109 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide and subnets as they are added or updated across your organization.

For information about policy scope and AWS Organizations, see Using the AWS Firewall Manager policy scope and the AWS Organizations User Guide. When you define a Firewall Manager network ACL policy, in addition to the standard Firewall Manager policy settings, such as name and scope, you provide the following: • First and last rules for inbound and outbound traffic handling. Firewall Manager enforces the presence and ordering of these in the network ACLs that are in scope of the policy, or reports noncompliance. Your individual accounts can create custom rules to run in between the policy's first and last rules. • Whether to force remediation when remediation would result in traffic management conflicts between the rules in the network ACL. This applies only when remediation is enabled for the policy. Best practices for using Firewall Manager network ACL policies This section lists recommendations for working with Firewall Manager network ACL policies and managed network ACLs. Refer to the FMManaged tag to identify network ACLs that are managed by Firewall Manager The network ACLs that Firewall Manager manages have the FMManaged tag set to true. Use this tag to help distinguish your own custom network ACLs from those that you're managing through Firewall Manager. Don't modify the value of the FMManaged tag on a network ACL Firewall Manager uses this tag to set and determine its management status with a network ACL. Don't modify the associations for subnets that have Firewall Manager managed network ACLs Don't manually change the associations between your subnets and any network ACLs that are managed by Firewall Manager. Doing so can disable the ability of Firewall Manager to manage protections for those subnets. You can identify network ACLs that are managed by Firewall Manager by looking for the FMManaged tag settings of true. To remove a subnet from Firewall Manager policy management, use the Firewall Manager policy scope settings to exclude the subnet. For example, you can tag the subnet and then exclude that tag from policy scope. For more information, see Using the AWS Firewall Manager policy scope. Network ACL policies 1110 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide When you update a managed network ACL, don't modify the rules that are managed by Firewall Manager In a network ACL that's managed by Firewall Manager, keep your custom rules separated from the policy rules by adhering to the numbering scheme described in Using network ACL rules and tagging in Firewall Manager. Only add or modify rules that have numbers between 5,000 and 32,000. Avoid adding too many rules for your account limits During remediation of a network ACL, Firewall Manager usually increases the network ACL rule count temporarily. To avoid noncompliance problems, make sure you have enough room for the rules you're using. For more information, see How Firewall Manager remediates noncompliant managed network ACLs. Start with automatic remediation disabled Start with automatic remediation disabled, and then review the policy details information to determine the effects that automatic remediation would have. When you are satisfied that the changes are what you want, edit the policy to enable automatic remediation. Firewall Manager network ACL policy caveats This section lists the caveats and limitations for using Firewall Manager network ACL policies. • Slower update times than with other policies – Firewall Manager generally applies network ACL policies and policy changes more slowly than with other Firewall Manager policies, due to limitations in the rate at which the Amazon EC2 network ACL APIs are able to process requests. You might notice that policy changes take longer than similar changes with other Firewall Manager policies, in particular when you first add a policy. • For initial subnet protection, Firewall Manager prefers older policies – This applies only to subnets that aren't yet protected by a Firewall Manager network ACL policy. If a subnet comes into scope of more than one network ACL policy at the same time, then Firewall Manager uses the oldest policy to protect the subnet. • Reasons for a policy to stop protecting a subnet – A policy that's managing the network ACL for a subnet retains management until one of the following happens: • The subnet goes out of scope of the policy. • The policy is |
waf-dg-422 | waf-dg.pdf | 422 | a policy. • For initial subnet protection, Firewall Manager prefers older policies – This applies only to subnets that aren't yet protected by a Firewall Manager network ACL policy. If a subnet comes into scope of more than one network ACL policy at the same time, then Firewall Manager uses the oldest policy to protect the subnet. • Reasons for a policy to stop protecting a subnet – A policy that's managing the network ACL for a subnet retains management until one of the following happens: • The subnet goes out of scope of the policy. • The policy is deleted. Network ACL policies 1111 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • You manually change the subnet's association to a network ACL that's managed by a different Firewall Manager policy and for which the subnet is in scope. Topics • Using network ACL rules and tagging in Firewall Manager • How Firewall Manager initiates network ACL management for a subnet • How Firewall Manager remediates noncompliant managed network ACLs • Deleting a Firewall Manager network ACL policy Using network ACL rules and tagging in Firewall Manager This section describes the network ACL policy rule specifications and the network ACLs that are managed by Firewall Manager. Tagging on a managed network ACL Firewall Manager tags a managed network ACL with a FMManaged tag that has a value of true. Firewall Manager only performs remediation on network ACLs that have this tag setting. Rules that you define in the policy In your network ACL policy specification, you define the rules that you want to run first and last for inbound traffic and the rules that you want to run first and last for outbound traffic. By default, you can define up to 5 inbound rules, for use in any combination of first and last rules in the policy. Similarly, you can define up to 5 outbound rules. For more about these limits, see Soft quotas. For information about the general limits on network ACLs, see Amazon VPC quotas on network ACLs in the Amazon VPC User Guide. You don't assign rule numbers to the policy rules. Instead, you specify the rules in the order you want them to be evaluated, and Firewall Manager uses that ordering to assign rule numbers in the network ACLs that it manages. Other than this, you manage the policy's network ACL rules specifications as you would manage the rules in a network ACL through Amazon VPC. For information about network ACL management in Amazon VPC, see Control traffic to subnets using network ACLs and Work with network ACLs in the Amazon VPC User Guide. Network ACL policies 1112 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Rules in a managed network ACL Firewall Manager configures the rules in a network ACL that it manages by placing the policy's first and last rules before and after any custom rules that an individual account manager defines. Firewall Manager preserves the order of the custom rules. Network ACLs are evaluated starting with the lowest numbered rule. When Firewall Manager first creates a network ACL, it defines the rules with the following numbering: • First rules: 1, 2, ... – Defined by you in the Firewall Manager network ACL policy. Firewall Manager assigns rule numbers starting from 1 with increments of 1, with the rules ordered as you have ordered them in the policy specification. • Custom rules: 5,000, 5,100, ... – Managed by individual account managers through Amazon VPC. Firewall Manager assigns numbers to these rules starting from 5,000 and incrementing by 100 for each subsequent rule. • Last rules: ... 32,765, 32,766 – Defined by you in the Firewall Manager network ACL policy. Firewall Manager assigns rule numbers that end at the highest possible number, 32766 with increments of 1, with the rules ordered as you have ordered them in the policy specification. After network ACL initialization, Firewall Manager doesn't control changes that individual accounts make in its managed network ACLs. Individual accounts can change a network ACL without taking it out of compliance, providing any custom rules remain numbered in between the policy's first and last rules, and the first and last rules maintain their specified ordering. As a best practice, when managing custom rules, adhere to the numbering described in this section. How Firewall Manager initiates network ACL management for a subnet This section describes how Firewall Manager initiates network ACL management for a subnet. Firewall Manager begins management of the network ACL for a subnet when it associates the subnet with a network ACL that Firewall Manager has created and tagged with FMManaged set to true. Compliance with a network ACL policy requires the subnet's network ACL to have the policy's first rules positioned first, in the order |
waf-dg-423 | waf-dg.pdf | 423 | and last rules maintain their specified ordering. As a best practice, when managing custom rules, adhere to the numbering described in this section. How Firewall Manager initiates network ACL management for a subnet This section describes how Firewall Manager initiates network ACL management for a subnet. Firewall Manager begins management of the network ACL for a subnet when it associates the subnet with a network ACL that Firewall Manager has created and tagged with FMManaged set to true. Compliance with a network ACL policy requires the subnet's network ACL to have the policy's first rules positioned first, in the order specified in the policy, the last rules positioned last, in order, Network ACL policies 1113 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide and any other custom rules positioned in the middle. These requirements can be satisfied by an unmanaged network ACL that the subnet is already associated with or by a managed network ACL. When Firewall Manager applies a network ACL policy to a subnet that's associated with an unmanaged network ACL, Firewall Manager checks the following in order, stopping when it identifies a viable option: 1. The associated network ACL is already compliant – If the network ACL that's currently associated with the subnet is compliant, then Firewall Manager leaves that association in place and does not start network ACL management for the subnet. Firewall Manager doesn't alter or otherwise manage a network ACL that it doesn't own, but as long as it's compliant, Firewall Manager leaves it in place and just monitors it for policy compliance. 2. A compliant managed network ACL is available – If Firewall Manager is already managing a network ACL that complies with the required configuration, then this is an option. If remediation is enabled, Firewall Manager associates the subnet to it. If remediation is disabled, Firewall Manager marks the subnet noncompliant and offers replacing the network ACL association as a remediation option. 3. Create a new compliant managed network ACL – If remediation is enabled, Firewall Manager creates a new network ACL and associates it with the subnet. Otherwise, Firewall Manager marks the subnet noncompliant and offers the remediation options of creating the new network ACL and replacing the network ACL association. If these steps fail, Firewall Manager reports noncompliance for the subnet. Firewall Manager follows these steps when a subnet first comes into scope and when a subnet's unmanaged network ACL is out of compliance. How Firewall Manager remediates noncompliant managed network ACLs This section describes how Firewall Manager remediates its managed network ACLs when they're out of compliance with the policy. Firewall Manager only remediates managed network ACLs—with the FMManaged tag set to true. For network ACLs that aren't managed by Firewall Manager, see Initial network ACL management. Remediation restores the relative locations of the first, custom, and last rules and restores the ordering for first and last rules. During remediation, Firewall Manager won't necessarily move rules Network ACL policies 1114 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide to the rule numbers that it uses in network ACL initialization. For the initial number settings and descriptions of these rule categories, see Initial network ACL management. In order to establish compliant rules and rule ordering, Firewall Manager might need to move rules around inside the network ACL. As much as possible, Firewall Manager preserves the network ACL's protections by maintaining existing compliant rule ordering as it does this. For example, it might temporarily duplicate rules to new locations, and then perform an ordered removal of the original rules, preserving relative locations during the process. This approach protects your settings, but it also requires space in the network ACL for the interim rules. If Firewall Manager hits the limit for rules in a network ACL, it will halt remediation. When this happens, the network ACL remains out of compliance and Firewall Manager reports the reason. If an account adds custom rules to a network ACL that's managed by Firewall Manager, and those rules interfere with Firewall Manager remediation, Firewall Manager stops any remediation activities on the network ACL and reports the conflict. Forced remediation If you choose auto remediation for the policy, you also specify whether to force remediation for the first rules or last rules. When Firewall Manager encounters a conflict in traffic handling between a custom rule and a policy rule, it refers to the corresponding forced remediation setting. If forced remediation is enabled, Firewall Manager applies the remediation, in spite of the conflict. If this option isn't enabled, Firewall Manager halts remediation.

Rule count requirements and limitations During remediation, Firewall Manager might temporarily duplicate rules in order to move them without altering the protections that they provide. For either |
waf-dg-424 | waf-dg.pdf | 424 | whether to force remediation for the first rules or last rules. When Firewall Manager encounters a conflict in traffic handling between a custom rule and a policy rule, it refers to the corresponding forced remediation setting. If forced remediation is enabled, Firewall Manager applies the remediation, in spite of the conflict. If this option isn't enabled, Firewall Manager halts remediation. In either case, Firewall Manager reports the rule conflict and offers remediation options. Rule count requirements and limitations During remediation, Firewall Manager might temporarily duplicate rules in order to move them without altering the protections that they provide. For either inbound or outbound rules, the greatest number of rules that Firewall Manager might require to perform remediation is the following: 2 * (the number of rules defined in the policy for the traffic direction) + the number of custom rules defined in the network ACL for the traffic direction Network ACL policies 1115 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Network ACLs and network ACL policies are bound by mutable rule limits. If Firewall Manager hits a limit in its remediation efforts, it stops trying to remediate and reports the noncompliance. To make room for Firewall Manager to perform its remediation activities, you might request a limit increase. Alternately, you can change the configuration in the policy or network ACL to reduce the number of rules used. For information about the network ACL limits, see Amazon VPC quotas on network ACLs in the Amazon VPC User Guide. When remediation fails While updating a network ACL, if Firewall Manager needs to stop for any reason, it doesn't roll back the changes, but instead leaves the network ACL in an interim state. If you see duplicate rules in a network ACL that has the FMManaged tag set to true, Firewall Manager is probably in the middle of remediating it. Changes might be partially complete for a period, but because of the approach Firewall Manager takes to remediation, this won't interrupt traffic or reduce the protection for associated subnets. When Firewall Manager doesn't completely remediate network ACLs that are out of compliance, it reports the noncompliance for the associated subnets and suggests possible remediation options. Retrying after remediation fails In most cases, if Firewall Manager fails to complete remediation changes to a network ACL, it will eventually retry the change. The exception to this is when remediation reaches the network ACL rule count limit or the VPC network ACL count limit. Firewall Manager can't perform remediation activities that take AWS resources over their limit settings. In these cases, you need to reduce counts or increase limits in order to proceed. For information about the limits, see Amazon VPC quotas on network ACLs in the Amazon VPC User Guide. Firewall Manager network ACL compliance reporting Firewall Manager monitors and reports compliance for all network ACLs that are attached to in- scope subnets. Generally speaking, noncompliance occurs for situations such as incorrect rule ordering or a conflict in traffic handling behavior between policy rules and custom rules. Noncompliance reporting includes compliance violations and remediation options. Network ACL policies 1116 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Firewall Manager reports compliance violations for a network ACL policy in the same way as for other policy types. For information about compliance reporting, see Viewing compliance information for an AWS Firewall Manager policy. Noncompliance during policy updates After you modify a network ACL policy, until Firewall Manager updates the network ACLs that are in scope of the policy, Firewall Manager marks those network ACLs noncompliant. Firewall Manager does this even if the network ACLs might, strictly speaking, be in compliance. For example, if you remove rules from the policy specification, while in-scope network ACLs still have the extra rules, their rule definitions might still comply with the policy. However, since the extra rules are part of the rules that Firewall Manager is managing, Firewall Manager views them as violations of current policy settings. This is different from how Firewall Manager views custom rules that you add to the Firewall Manager managed network ACLs. Deleting a Firewall Manager network ACL policy This section describes what happens in Firewall Manager when you delete a Firewall Manager network ACL policy. When you delete a Firewall Manager network ACL policy, Firewall Manager changes the FMManaged tag values to false on all network ACLs that it's been managing for the policy. Additionally, you can choose whether to clean up the resources created by the policy. If you choose clean up, Firewall Manager tries the following steps in order: 1. Put the association back to the original – Firewall Manager tries to associate the subnet back to the network ACL that it was associated with before Firewall Manager started managing it. 2. Remove first and last |

When you delete a Firewall Manager network ACL policy, Firewall Manager changes the FMManaged tag values to false on all network ACLs that it's been managing for the policy. Additionally, you can choose whether to clean up the resources created by the policy. If you choose clean up, Firewall Manager tries the following steps in order: 1. Put the association back to the original – Firewall Manager tries to associate the subnet back to the network ACL that it was associated with before Firewall Manager started managing it. 2. Remove first and last rules from the network ACL – If it can't change the association, Firewall Manager tries to remove the policy's first and last rules, leaving only the custom rules in the network ACL that's associated with the subnet. 3. Do nothing to the rules or the association – If it can't do either of the above things, Firewall Manager leaves the network ACL and its association as they are. If you don't choose the cleanup option, you'll need to manually manage each network ACL after the policy is deleted. For most situations, choosing the cleanup option is the simplest approach. Network ACL policies 1117 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Using AWS Network Firewall policies in Firewall Manager This section explains how to use AWS Network Firewall policies with Firewall Manager. You can use AWS Firewall Manager Network Firewall policies to manage AWS Network Firewall firewalls for your Amazon Virtual Private Cloud VPCs across your organization in AWS Organizations. You can apply centrally controlled firewalls to your entire organization or to a select subset of your accounts and VPCs. Network Firewall provides network traffic filtering protections for the public subnets in your VPCs. Firewall Manager creates and manages your firewalls based on the firewall management type defined by your policy. Firewall Manager provides the following firewall management models: • Distributed - For each account and VPC that's within policy scope, Firewall Manager creates a Network Firewall firewall and deploys firewall endpoints to VPC subnets, to filter network traffic. • Centralized - Firewall Manager creates a single Network Firewall firewall in a single Amazon VPC. • Import existing firewalls - Firewall Manager imports existing firewalls for management in a single Firewall Manager policy. You can apply additional rules to the imported firewalls managed by your policy to ensure that your firewalls meet your security standards. Note Firewall Manager Network Firewall policies are Firewall Manager policies that you use to manage Network Firewall protections for your VPCs across your organization. The Network Firewall protections are specified in resources in the Network Firewall service that are called firewall policies. For information about using Network Firewall, see the AWS Network Firewall Developer Guide. The following sections cover requirements for using Firewall Manager Network Firewall policies and describe how the policies work. For the procedure for creating the policy, see Creating an AWS Firewall Manager policy for AWS Network Firewall. Important You must enable resource sharing. A Network Firewall policy shares Network Firewall rule groups across the accounts in your organization. For this to work, you must have resource Network Firewall policies 1118 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide sharing enabled for AWS Organizations. For information about how to enable resource sharing, see Resource sharing for Network Firewall and DNS Firewall policies. Important You must have your Network Firewall rule groups defined. When you specify a new Network Firewall policy, you define the firewall policy the same as you do when you're using AWS Network Firewall directly. You specify the stateless rule groups to add, default stateless actions, and stateful rule groups. Your rule groups must already exist in the Firewall Manager administrator account for you to include them in the policy. For information about creating Network Firewall rule groups, see AWS Network Firewall rule groups.

The Firewall management type in your policy determines how Firewall Manager creates firewalls. Your policy can create distributed firewalls, a centralized firewall, or you can import existing firewalls: • Distributed - With the distributed deployment model, Firewall Manager creates endpoints for each VPC that's within policy scope.

The Firewall management type in your policy determines how Firewall Manager creates firewalls. Your policy can create distributed firewalls, a centralized firewall, or you can import existing firewalls: • Distributed - With the distributed deployment model, Firewall Manager creates endpoints for each VPC that's within policy scope. You can either customize the endpoint location by specifying which Availability Zones to create firewall endpoints in, or Firewall Manager can automatically create endpoints in the Availability Zones with public subnets. If you manually choose the Availability Zones, you have the option to restrict the set of allowed CIDRs per Availability Zone. Network Firewall policies 1119 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide If you decide to let Firewall Manager automatically create the endpoints, you must also specify whether the service will create a single endpoint or multiple firewall endpoints within your VPCs. • For multiple firewall endpoints, Firewall Manager deploys a firewall endpoint in each Availability Zone where you have a subnet with an internet gateway or a Firewall Manager- created firewall endpoint route in the route table. This is the default option for a Network Firewall policy. • For a single firewall endpoint, Firewall Manager deploys a firewall endpoint in a single Availability Zone in any subnet that has an internet gateway route. With this option, traffic in other zones needs to cross zone boundaries in order to be filtered by the firewall. Note For both of these options, there must be a subnet associated to a route table that has an IPv4/prefixlist route in it. Firewall Manager does not check for any other resources. • Centralized - With the centralized deployment model, Firewall Manager creates one or more firewall endpoints within an inspection VPC. An inspection VPC is a central VPC where Firewall Manager launches your endpoints. When you use the centralized deployment model, you also specify which Availability Zones to create firewall endpoints in. You can't change the inspection VPC after you create your policy. To use a different inspection VPC, you must create a new policy. • Import existing firewalls - When you import existing firewalls, you choose the firewalls to manage in your policy by adding one or more resource sets to your policy. A resource set is a collection of resources, in this case existing firewalls in Network Firewall, that are managed by an account in your organization. Before you use resource sets in your policy, you must first create a resource set. For information about Firewall Manager resource sets, see Grouping your resources in Firewall Manager. Keep in mind the following considerations when working with imported firewalls: • If an imported firewall become non-compliant, Firewall Manager will try to automatically resolve the violation, except for under the following circumstances: • If there's a mismatch between the Firewall Manager and Network Firewall policy's stateful or stateless default actions. • If a rule group in an imported firewall's firewall policy has the same priority as a rule group in the Firewall Manager policy. Network Firewall policies 1120 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • If an imported firewall uses a firewall policy that's associated with a firewall that's not part of the policy's resource set. This can happen because a firewall can have exactly one firewall policy, but a single firewall policy can be associated with multiple firewalls. • If a pre-existing rule group belonging to an imported firewall's firewall policy that is also specified in the Firewall Manager policy is given a different priority. • If you enable resource cleanup in the policy, Firewall Manager removes the rule groups which have been in FMS import policy from the firewalls in scope of the resource set. • Firewalls managed by that are managed by a Firewall Manager import existing firewall management type can only be managed by one policy at a time. If the same resource set is added to multiple import network firewall policies, the firewalls in the resource set will be managed by the first policy the resource set was added to and will be ignored by the second policy. • Firewall Manager doesn't currently stream exception policy configurations. For information about stream exception policies, see Stream exception policy in the AWS Network Firewall Developer Guide. If you change the list of Availability Zones for policies using distributed or centralized firewall management, Firewall Manager will try to clean up any endpoints that were created in the past, but that aren't currently in policy scope. Firewall Manager will remove the endpoint only if there are no route table routes that reference the out of scope endpoint. If Firewall Manager finds that it is unable to delete these endpoints, it will mark the firewall subnet as |

For information about stream exception policies, see Stream exception policy in the AWS Network Firewall Developer Guide. If you change the list of Availability Zones for policies using distributed or centralized firewall management, Firewall Manager will try to clean up any endpoints that were created in the past, but that aren't currently in policy scope. Firewall Manager will remove the endpoint only if there are no route table routes that reference the out of scope endpoint. If Firewall Manager finds that it is unable to delete these endpoints, it will mark the firewall subnet as being non-compliant and will continue attempting to remove the endpoint until such time as it is safe to delete. How Firewall Manager manages your firewall subnets This section explains how Firewall Manager manages your firewall subnets. Firewall subnets are the VPC subnets that Firewall Manager creates for the firewall endpoints that filter your network traffic. Each firewall endpoint must be deployed in a dedicated VPC subnet. Firewall Manager creates at least one firewall subnet in each VPC that's within scope of the policy. For policies that use the distributed deployment model with automatic endpoint configuration, Firewall Manager only creates firewall subnets in Availability Zones that have a subnet with an internet gateway route, or a subnet with a route to the firewall endpoints that Firewall Manager created for their policy. For more information, see VPCs and subnets in the Amazon VPC User Guide. Network Firewall policies 1121 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide For policies that use either the distributed or centralized model where you specify which Availability Zones Firewall Manager creates the firewall endpoints in, Firewall Manager creates an endpoint in those specific Availability Zones irrespective of whether there are other resources in the Availability Zone. When you first define a Network Firewall policy, you specify how Firewall Manager manages the firewall subnets in each of the VPCs that are in scope. You cannot change this choice later. For policies that use the distributed deployment model with automatic endpoint configuration, you can choose between the following options: • Deploy a firewall subnet for every Availability Zone that has public subnets. This is the default behavior. This provides high availability of your traffic filtering protections. • Deploy a single firewall subnet in one Availability Zone. With this choice, Firewall Manager identifies a zone in the VPC that has the most public subnets and creates the firewall subnet there. The single firewall endpoint filters all network traffic for the VPC. This can reduce firewall costs, but it isn't highly available and it requires traffic from other zones to cross zone boundaries in order to be filtered. For policies that use distributed deployment model with custom endpoint configuration or the centralized deployment model, Firewall Manager creates the subnets in the specified Availability Zones that are within the policy scope. You can provide VPC CIDR blocks for Firewall Manager to use for the firewall subnets or you can leave the choice of firewall endpoint addresses up to Firewall Manager to determine. • If you don't provide CIDR blocks, Firewall Manager queries your VPCs for available IP addresses to use. • If you provide a list of CIDR blocks, Firewall Manager searches for new subnets only in the CIDR blocks that you provide. You must use /28 CIDR blocks. For each firewall subnet that Firewall Manager creates, it walks your CIDR block list and uses the first one that it finds that is applicable to the Availability Zone and VPC and has available addresses. If Firewall Manager is unable to find open space in the VPC (with or without the restriction), the service won't create a firewall in the VPC. If Firewall Manager can't create a required firewall subnet in an Availability Zone, it marks the subnet as non-compliant with the policy. While the zone is in this state, traffic for the zone must Network Firewall policies 1122 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide cross zone boundaries in order to be filtered by an endpoint in another zone. This is similar to the single firewall subnet scenario. How Firewall Manager manages your Network Firewall resources This section describes how you manage your Network Firewall resources in Firewall Manager. When you define the policy in Firewall Manager, you provide the network traffic filtering behavior of a standard AWS Network Firewall firewall policy. You add stateless and stateful Network Firewall rule groups and specify default actions for packets that don’t match any stateless rules. For information on working with firewall policies in AWS Network Firewall, see the AWS Network Firewall firewall policies. For distributed and centralized policies, when you save the Network Firewall policy, Firewall Manager creates a firewall and firewall policy in each VPC that's |

You add stateless and stateful Network Firewall rule groups and specify default actions for packets that don’t match any stateless rules. For information on working with firewall policies in AWS Network Firewall, see the AWS Network Firewall firewall policies. For distributed and centralized policies, when you save the Network Firewall policy, Firewall Manager creates a firewall and firewall policy in each VPC that's within scope of the policy. Firewall Manager names these Network Firewall resources by concatenating the following values: • A fixed string, either FMManagedNetworkFirewall or FMManagedNetworkFirewallPolicy, depending on the resource type. • Firewall Manager policy name. This is the name you assign when you create the policy. • Firewall Manager policy ID. This is the AWS resource ID for the Firewall Manager policy. • Amazon VPC ID. This is the AWS resource ID for the VPC where Firewall Manager creates the firewall and firewall policy. The following shows an example name for a firewall that's managed by Firewall Manager: FMManagedNetworkFirewallEXAMPLENameEXAMPLEFirewallManagerPolicyIdEXAMPLEVPCId The following shows an example firewall policy name: FMManagedNetworkFirewallPolicyEXAMPLENameEXAMPLEFirewallManagerPolicyIdEXAMPLEVPCId After you create the policy, member accounts in the VPCs can't override your firewall policy settings or your rule groups, but they can add rule groups to the firewall policy that Firewall Manager has created. How Firewall Manager manages and monitors VPC route tables for your policy This section explains how Firewall Manager manages and monitors your VPC route tables. Network Firewall policies 1123 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Note Route table management isn't currently supported for policies that use the centralized deployment model. When Firewall Manager creates your firewall endpoints, it also creates the VPC route tables for them. However, Firewall Manager doesn't manage your VPC route tables. You must configure your VPC route tables to direct network traffic to the firewall endpoints that are created by Firewall Manager. Using Amazon VPC ingress routing enhancements, change your routing tables to route traffic through the new firewall endpoints. Your changes must insert the firewall endpoints between the subnets that you want to protect and outside locations. The exact routing that you need to do depends on your architecture and its components. Currently, Firewall Manager allows monitoring of your VPC route table routes for any traffic destined to the internet gateway, that is bypassing the firewall. Firewall Manager doesn't support other target gateways like NAT gateways. For information about managing route tables for your VPC, see Managing route tables for your VPC in the Amazon Virtual Private Cloud User Guide. For information about managing your route tables for Network Firewall, see Route table configurations for AWS Network Firewall in the AWS Network Firewall Developer Guide. When you enable monitoring for a policy, Firewall Manager continuously monitors VPC route configurations and alerts you about traffic that bypasses firewall inspection for that VPC. If a subnet has a firewall endpoint route, Firewall Manager looks for the following routes: • Routes to send traffic to the Network Firewall endpoint. • Routes to forward the traffic from the Network Firewall endpoint to the internet gateway. • Inbound routes from the internet gateway to the Network Firewall endpoint. • Routes from the firewall subnet. If a subnet has a Network Firewall route but there's asymmetric routing in Network Firewall and your internet gateway route table, Firewall Manager reports the subnet as non-compliant. Firewall Manager also detects routes to the internet gateway in the firewall route table that Firewall Manager created, as well as the route table for your subnet, and reports them as non-compliant. Additional routes in the Network Firewall subnet route table and your internet gateway route table Network Firewall policies 1124 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide are also reported as non-compliant. Depending on the violation type, Firewall Manager suggests remediation actions to bring the route configuration into compliance. Firewall Manager doesn't offer suggestions in all cases. For example, if your customer subnet has a firewall endpoint that was created outside of Firewall Manager, Firewall Manager doesn't suggest remediation actions. By default, Firewall Manager will mark any traffic that crosses the Availability Zone boundary for inspection as being non-compliant. However, if the you choose to automatically create a single endpoint in your VPC, Firewall Manager won't mark traffic that crosses the Availability Zone boundary as non-compliant. For policies that use distributed deployment models with custom endpoint configuration, you can choose whether the traffic crossing the Availability Zone boundary from an Availability Zone without a firewall endpoint is marked as compliant or non-compliant. Note • Firewall Manager does not suggest remediation actions for non-IPv4 routes, such |
waf-dg-429 | waf-dg.pdf | 429 | Manager doesn't suggest remediation actions. By default, Firewall Manager will mark any traffic that crosses the Availability Zone boundary for inspection as being non-compliant. However, if the you choose to automatically create a single endpoint in your VPC, Firewall Manager won't mark traffic that crosses the Availability Zone boundary as non-compliant. For policies that use distributed deployment models with custom endpoint configuration, you can choose whether the traffic crossing the Availability Zone boundary from an Availability Zone without a firewall endpoint is marked as compliant or non-compliant. Note • Firewall Manager does not suggest remediation actions for non-IPv4 routes, such as IPv6 and prefix list routes. • Calls made using the DisassociateRouteTable API call can take up to 12 hours to detect. • Firewall Manager creates a Network Firewall route table for a subnet that contains the firewall endpoints. Firewall Manager assumes that this route table contains only valid internet gateway and VPC default routes. Any extra or invalid routes in this route table are considered to be non-compliant. When you configure your Firewall Manager policy, if you choose Monitor mode, Firewall Manager provides resource violation and remediation details about your resources. You can use these suggested remediation actions to fix route issues in your route tables. If you choose Off mode, Firewall Manager doesn't monitor your route table content for you. With this option, you manage your VPC route tables for yourself. For more information about these resource violations, see Viewing compliance information for an AWS Firewall Manager policy. Network Firewall policies 1125 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Warning If you choose Monitor under AWS Network Firewall route configuration when creating your policy, you can't turn it off for that policy. However, if you choose Off, you can enable it later. Configuring logging for an AWS Network Firewall policy This section explains how you can enable centralized logging for your Network Firewall policies to get detailed information about traffic within your organization. You can select flow logging to capture network traffic flow, or alert logging to report traffic that matches a rule with the rule action set to DROP or ALERT. For more information about AWS Network Firewall logging, see Logging network traffic from AWS Network Firewall in the AWS Network Firewall Developer Guide. You send logs from your policy's Network Firewall firewalls to an Amazon S3 bucket. After you enable logging, AWS Network Firewall delivers logs for each configured Network Firewall by updating the firewall settings to deliver logs to your selected Amazon S3 buckets with the reserved AWS Firewall Manager prefix, <policy-name>-<policy-id>. Note This prefix is used by Firewall Manager to determine whether a logging configuration was added by Firewall Manager, or whether it was added by the account owner. If the account owner attempts to use the reserved prefix for their own custom logging, it is overwritten by the logging configuration in the Firewall Manager policy. For more information about how to create an Amazon S3 bucket and review the stored logs, see What is Amazon S3? in the Amazon Simple Storage Service User Guide. To enable logging you must meet the following requirements: • The Amazon S3 that you specify in your Firewall Manager policy must exist. • You must have the following permissions: • logs:CreateLogDelivery • s3:GetBucketPolicy • s3:PutBucketPolicy Network Firewall policies 1126 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • If the Amazon S3 bucket that's your logging destination uses server-side encryption with keys that are stored in AWS Key Management Service, you must add the following policy to your AWS KMS customer-managed key to allow Firewall Manager to log to your CloudWatch Logs log group: { "Effect": "Allow", "Principal": { "Service": "delivery.logs.amazonaws.com" }, "Action": [ "kms:Encrypt*", "kms:Decrypt*", "kms:ReEncrypt*", "kms:GenerateDataKey*", "kms:Describe*" ], "Resource": "*" } Note that only buckets in the Firewall Manager administrator account may be used for AWS Network Firewall central logging. When you enable centralized logging on a Network Firewall policy, Firewall Manager takes these actions on your account: • Firewall Manager updates the permissions on selected S3 buckets to allow for log delivery. • Firewall Manager creates directories in the S3 bucket for each member account in the scope of the policy. The logs for each account can be found at <bucket-name>/<policy-name>- <policy-id>/AWSLogs/<account-id>. To enable logging for a Network Firewall policy 1. Create an Amazon S3 bucket using your Firewall Manager administrator account. For more information, see Creating a bucket in the Amazon Simple Storage Service User Guide. 2.

Using Amazon Route 53 Resolver DNS Firewall policies in Firewall Manager This page describes how you can use AWS Firewall Manager DNS Firewall policies to manage associations between Amazon Route 53 Resolver DNS Firewall rule groups and your Amazon Virtual Private Cloud VPCs across your organization in AWS Organizations. You can apply centrally controlled rule groups to your entire organization, or to a select subset of your accounts and VPCs. DNS Firewall provides filtering and regulation of outbound DNS traffic for your VPCs. You create reusable collections of filtering rules in DNS Firewall rule groups and you associate the rule groups to your VPCs. When you apply the Firewall Manager policy, for each account and VPC that's within policy scope, Firewall Manager creates an association between each DNS Firewall rule group in the policy and each VPC that's within scope of the policy, using the association priority settings that you specify in the Firewall Manager policy. For information about using DNS Firewall, see Amazon Route 53 Resolver DNS Firewall in the Amazon Route 53 Developer Guide. The following sections cover requirements for using Firewall Manager DNS Firewall policies and describe how the policies work. For the procedure for creating the policy, see Creating an AWS Firewall Manager policy for Amazon Route 53 Resolver DNS Firewall. Important You must enable resource sharing. A DNS Firewall policy shares DNS Firewall rule groups across the accounts in your organization. For this to work, you must have resource sharing enabled with AWS Organizations. For information about how to enable resource sharing, see Resource sharing for Network Firewall and DNS Firewall policies. DNS Firewall policies 1129 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Important You must have your DNS Firewall rule groups defined.

When you specify a new DNS Firewall policy, you define the rule groups the same as you do when you're using Amazon Route 53 Resolver DNS Firewall directly. Your rule groups must already exist in the Firewall Manager administrator account for you to include them in the policy. For information about creating DNS Firewall rule groups, see DNS Firewall rule groups and rules. You define the lowest and highest priority rule group associations The DNS Firewall rule group associations that you manage through Firewall Manager DNS Firewall policies contain the lowest priority associations and the highest priority associations for your VPCs. In your policy configuration, these appear as first and last rule groups. DNS Firewall filters DNS traffic for the VPC in the following order: 1. First rule groups, defined by you in the Firewall Manager DNS Firewall policy. Valid values are between 1 and 99. 2. DNS Firewall rule groups that are associated by individual account managers through DNS Firewall. 3. Last rule groups, defined by you in the Firewall Manager DNS Firewall policy. Valid values are between 9,901 and 10,000. How Firewall Manager names the rule group associations that it creates When you save the DNS Firewall policy, if you enabled autoremediation, Firewall Manager creates a DNS Firewall association between the rule groups that you provided in the policy and the VPCs that are in scope of the policy. Firewall Manager names these associations by concatenating the following values: • The fixed string, FMManaged_. • The Firewall Manager policy ID. This is the AWS resource ID for the Firewall Manager policy. The following shows an example name for a firewall that's managed by Firewall Manager: FMManaged_EXAMPLEDNSFirewallPolicyId DNS Firewall policies 1130 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide After you create the policy, if account owners in the VPCs override your firewall policy settings or your rule group associations then Firewall Manager will mark the policy as non-compliant and try to propose a remedial action. Account owners can associate other DNS Firewall rule groups to the VPCs that are in scope of the DNS Firewall policy. Any associations that are created by the individual account owners must have priority settings between your first and last rule group associations. Deleting a rule group from a Firewall Manager DNS Firewall policy Deleting a rule group To delete a rule group from a Firewall Manager DNS Firewall policy, you must perform the following steps: 1. Remove the rule group from your Firewall Manager DNS Firewall policy. 2. Unshare the rule group in AWS Resource Access Manager. To unshare a rule group that you own, you must remove it from the resource share. You can do this using the AWS RAM console or the AWS CLI. For information about unsharing a resource, see Update a resource share in AWS RAM in the AWS RAM User Guide. 3. Delete the rule group using the DNS Firewall console or AWS CLI. Using Palo Alto Networks Cloud NGFW policies for Firewall Manager The Palo Alto Networks Cloud Next Generation Firewall (NGFW) is a third-party firewall service that you can use for your AWS Firewall Manager policies. With Palo Alto Networks Cloud NGFW for Firewall Manager, you can create and centrally deploy Palo Alto Networks Cloud NGFW resources and rulestacks across all of your AWS accounts. To use Palo Alto Networks Cloud NGFW with Firewall Manager, you first subscribe to the Palo Alto Networks Cloud NGFW Pay-As-You-Go service in the AWS Marketplace.

Resource sharing for Network Firewall and DNS Firewall policies To manage Firewall Manager Network Firewall and DNS Firewall policies, you must enable resource sharing with AWS Organizations in AWS Resource Access Manager. This allows Firewall Manager to deploy protections across your accounts when you create these policy types. To enable resource sharing, follow the instructions at Enable Sharing with AWS Organizations in the AWS Resource Access Manager User Guide. Problems with resource sharing You might encounter problems with resource sharing, either when you use AWS RAM to enable it, or when you're working on Firewall Manager policies that require it. Examples of these problems include the following: Fortigate CNF policies 1132 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • When you follow the instructions to enable sharing, in the AWS RAM console, the choice Enable sharing with AWS Organizations is grayed out and not available for selection. • When you work in Firewall Manager on a policy that requires resource sharing, the policy is marked as non-compliant and you see messages indicating that resource sharing or AWS RAM isn't enabled. If you encounter problems with resource sharing, use the following procedure to try to enable it. Try again to enable resource sharing • Try again to enable sharing using one of the following options: • (Option) Through the AWS RAM console, follow the instructions at Enable Sharing with AWS Organizations in the AWS Resource Access Manager User Guide. • (Option) Using the AWS RAM API, call EnableSharingWithAwsOrganization. See the documentation at EnableSharingWithAwsOrganization. Using Firewall Manager managed lists This section explains what managed lists are and how to use them. Managed application and protocol lists streamline your configuration and management of AWS Firewall Manager content audit security group policies. You use managed lists to define the protocols and applications that your policy allows and disallows. For information about content audit security group policies, see Using content audit security group policies with Firewall Manager. You can use the following types of managed lists in a content audit security group policy: • Firewall Manager application lists and protocol lists – Firewall Manager manages these lists. • The application lists include FMS-Default-Public-Access-Apps-Allowed and FMS- Default-Public-Access-Apps-Denied, which describe commonly used applications that should be allowed or denied to the general public. • The protocol lists include FMS-Default-Protocols-Allowed, a list of commonly used protocols that should be allowed to the general public. You can use any list that Firewall Manager manages, but you can't edit or delete it. Using managed lists 1133 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • Custom application lists and protocol lists – You manage these lists. You can create lists of either type with the settings that you need. You have full control over your own custom managed lists, and you can create, edit, and delete them as needed. Note Currently, Firewall Manager doesn't check references to a custom managed list when you delete it. This means that you can delete a custom managed application list or protocol list even when it is in use by an active policy. This can cause the policy to stop functioning. Delete an application list or protocol list only after you have verified that it isn't referenced by any active polices. Managed lists are AWS resources. You can tag a custom managed list.

Delete an application list or protocol list only after you have verified that it isn't referenced by any active polices. Managed lists are AWS resources. You can tag a custom managed list. You can't tag a Firewall Manager managed list. Managed list versioning Custom managed lists don't have versions. When you edit a custom list, policies that reference the list automatically use the updated list. Firewall Manager managed lists are versioned. The Firewall Manager service team publishes new versions as needed, in order to apply the best security practices to the lists. When you use a Firewall Manager managed list in a policy, you choose your versioning strategy as follows: • Latest available version – If you don't specify an explicit version setting for the list, then your policy automatically uses the latest version. This is the only option available through the console. • Explicit version – If you specify a version for the list, then your policy uses that version. Your policy remains locked to the version that you specified until you modify the version setting. To specify the version, you must define the policy outside of the console, for example through the CLI or one of the SDKs. For more information about choosing the version setting for a list, see Using managed lists in your content audit security group policies. Managed list versioning 1134 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Using managed lists in your content audit security group policies When you create a content audit security group policy, you can choose to use managed audit policy rules. Some of the settings for this option require a managed application list or protocol list. Examples of these settings include protocols that are allowed in security group rules and applications can access the internet. The following restrictions apply for each policy setting that uses a managed list: • You can specify at most one Firewall Manager managed list for any setting. By default, you can specify at most one custom list. The custom list limit is a soft quota, so you can request an increase to it. For more information, see AWS Firewall Manager quotas. • In the console, if you select a Firewall Manager managed list, you can't specify the version. The policy will always use the latest version of the list. To specify the version, you must define the policy outside of the console, for example through the CLI or one of the SDKs. For information about versioning for Firewall Manager managed lists, see Managed list versioning. For information about creating a content audit security group policy through the console, see Creating a content audit security group policy.

Deleting a custom managed list 1138 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Grouping your resources in Firewall Manager This section decribes what a resource set is and lists considerations for using resource sets. An AWS Firewall Manager resource set is a collection of resources, such as firewalls, that you can group together and manage in a Firewall Manager policy. Resource sets enable members in your organization to have granular control over what resources to manage in a policy. To use resource sets, create a resource set in the console or using the PutResourceSet API, then add the resource set to your Firewall Manager policy. You can create and manage resource sets for the following resource and security policy types: Resource type Firewall Manager security policy type AWS Network Firewall - firewalls Network Firewall policy - Use resource sets to import existing firewalls from Network |

For information about using resource sets in a Network Firewall policy, see the Importing existing firewalls step in the Creating an AWS Firewall Manager policy for AWS Network Firewall procedure. The following sections cover requirements for creating and deleting resource sets. Topics • Considerations when working with resource sets in Firewall Manager • Creating resource sets in Firewall Manager • Deleting a resource set in Firewall Manager Considerations when working with resource sets in Firewall Manager Note the following considerations when working with resource sets. References to non-existent resources When you add a resource to a resource set, you create a reference to the resource using an Amazon Resource Name (ARN). Firewall Manager validates that Amazon Resource Name (ARN) is the correct Grouping your resources 1139 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide format, but Firewall Manager doesn't check that the referenced resource exists. If the resource doesn't exist yet passes ARN validation, Firewall Manager includes the resource reference in the resource set. If a new resource with the same ARN is later created, Firewall Manager applies rule groups from the resource set's associated policy to the new resource. Deleted resources When a resource in a resource set is deleted, the reference to the resource remains in the resource set until it's removed by the Firewall Manager administrator. Resources owned by member account that leaves the AWS Organizations organization If a member account leaves the organization, any references to resources owned by that member account will remain in the resource set but will no longer be managed by any policies the resource set is associated with. Association to multiple policies A resource set can be associated with multiple policies, but not all policy types support multiple policies managing the same resource. See the documentation for your specific policy type for information about unsupported scenarios. Creating resource sets in Firewall Manager To create a resource set (console) 1. Sign in to the AWS Management Console using your Firewall Manager administrator account, and then open the Firewall Manager console at https://console.aws.amazon.com/wafv2/ fmsv2.

Viewing compliance information for an AWS Firewall Manager policy This section provides guidance for viewing the compliance status of accounts and resources that are in scope of an AWS Firewall Manager policy. For information about the controls in place at AWS to maintain security and compliance of the cloud, see Compliance validation for Firewall Manager. Deleting a resource set 1141 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Note In order for Firewall Manager to monitor policy compliance, AWS Config must continuously record configuration changes for protected resources. In your AWS Config configuration, the recording frequency must be set to Continuous, which is the default setting. Note To maintain proper compliance state in your protected resources, avoid repeatedly changing the state of the Firewall Manager protections, either automatically or manually. Firewall Manager uses information from AWS Config to detect changes to resource configurations. If changes are applied quickly enough, AWS Config can lose track of some of them, which can result in the loss of information about compliance or remediation state in Firewall Manager. If you see that a resource you're protecting with Firewall Manager has an incorrect compliance or remediation status, first make sure you're not running any process that alters or resets your Firewall Manager protections, then refresh the AWS Config tracking for the resource by reevaluating the associated configuration rules in AWS Config. If you modify the policy or in-scope resources, it may take several minutes before updates to the compliance status and details are visible. For all AWS Firewall Manager policies, you can view the compliance status for accounts and resources that are in scope of the policy. An account or resource is in compliance with a Firewall Manager policy if the settings in the policy are reflected in the settings for the account or resource. Each policy type has its own compliance requirements, which you can tune when you define the policy. For some policies, you can also view detailed violation information for in scope resources, to help you to better understand and manage your security risk. To view the compliance information for a policy 1. Sign in to the AWS Management Console using your Firewall Manager administrator account, and then open the Firewall Manager console at https://console.aws.amazon.com/wafv2/ fmsv2. For information about setting up a Firewall Manager administrator account, see AWS Firewall Manager prerequisites. Viewing compliance for a policy 1142 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Note For information about setting up a Firewall Manager administrator account, see AWS Firewall Manager prerequisites. 2. In the navigation pane, choose Security policies. 3. Choose a policy. In the Accounts and resources tab of the policy page, Firewall Manager lists the accounts in your organization, grouped by those that are within scope of the policy and those that are outside of scope. The Accounts within policy scope pane lists the compliancy status for each account. A Compliant status indicates that the policy has successfully been applied to all of in-scope resources for the account. A Noncompliant status indicates that the policy hasn't been applied to one or more of the in-scope resources for the account. 4. Choose an account that's noncompliant. In the account page, Firewall Manager lists the ID and type for each noncompliant resource and the reason that the resource is in violation of the policy. Note For the resource types AWS::EC2::NetworkInterface (ENI) and AWS::EC2::Instance, Firewall Manager might show a limited number of noncompliant resources. To list additional noncompliant resources, fix the ones that are initially displayed for the account. 5. If the Firewall Manager policy type is a content audit security group policy, you can access detailed violation information for a resource. To view violation details, choose the resource. Note Resources that Firewall Manager found to be noncompliant before the addition of the detailed resource violation page might not have violation details. Viewing compliance for a policy 1143 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide In the resource page, Firewall Manager lists specific details about the violation, according to resource type. • AWS::EC2::NetworkInterface (ENI) – Firewall Manager displays information about the security group that the resource doesn't comply with.

If Firewall Manager can't determine a safe remediation action, this field is blank. • AWS::EC2::Subnet – This is used for network ACL and Network Firewall policies. Firewall Manager displays the subnet ID, VPC ID, and Availability Zone. If applicable, Firewall Manager includes additional information about the violation. The violation description component contains a description of the expected state of the resource, the current, noncompliant state, and if available, a description of what caused the discrepancy. Network Firewall violations • Route management violations – For Network Firewall policies that use Monitor mode, Firewall Manager displays basic subnet information, as well as expected and actual routes in the subnet, internet gateway, and Network Firewall subnet route table. Firewall Manager alerts you that there's a violation if the actual routes don’t match the expected routes in the route table. • Remediation actions for route management violations – For Network Firewall policies that use Monitor mode, Firewall Manager suggests possible remediation actions on route configurations that have violations. Viewing compliance for a policy 1144 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide For example, say a subnet is expected to send traffic through the firewall endpoints, but the current subnet is sending traffic directly to the internet gateway. This is a route management violation. The suggested remediation in this case might be a list of ordered actions. The first being a recommendation to add the required routes to the Network Firewall subnet's route table to direct outgoing traffic to the internet gateway and to direct incoming traffic for destinations inside the VPC to `local`. The second recommendation is to replace the internet gateway route or the invalid Network Firewall route in the subnet's route table to direct outgoing traffic to the firewall endpoints. The third recommendation is to add required routes to the internet gateway's route table to direct incoming traffic to the firewall endpoints. • AWS::EC2:InternetGateway – This is used for Network Firewall policies that have Monitor mode enabled. • Route management violations – The internet gateway is noncompliant if the internet gateway is not associated with a route table, or if there is an invalid route in the internet gateway route table. • Remediation actions for route management violations – Firewall Manager suggests possible remediation actions to remedy route management violations. Example 1 – Route management violation and remediation suggestions An internet gateway is not associated with a route table. The suggested remediation actions might be a list of ordered actions. The first action is to create a route table. The second action is to associate the route table with the internet gateway. The third action is to add the required route to the internet gateway route table. Example 2 – Route management violation and remediation suggestions The internet gateway is associated with a valid route table, but the route is configured improperly. The suggested remediation might be a list of ordered actions. The first suggestion is to remove the invalid route. The second is to add the required route to the internet gateway route table. • AWS::NetworkFirewall::FirewallPolicy – This is used for Network Firewall policies. Firewall Manager displays information about a Network Firewall firewall policy that's been modified in a way that makes it noncompliant. The information provides the expected firewall policy and the policy that it found in the customer account, so you can compare stateless and stateful rule groups names and priority settings, custom action names, Viewing compliance for a policy 1145 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide and default stateless actions settings. The violation description component contains a description of the expected state of the resource, the current, noncompliant state, and if available, a description of what caused the discrepancy. • AWS::EC2::VPC – This is used for DNS Firewall policies.

DNS Firewall policy findings 1151 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide For information about protecting your AWS resources using Firewall Manager, see the rest of the Firewall Manager guide. Security is a shared responsibility between AWS and you. The shared responsibility model describes this as security of the cloud and security in the cloud: • Security of the cloud – AWS is responsible for protecting the infrastructure that runs AWS services in the AWS Cloud. AWS also provides you with services that you can use securely. The effectiveness of our security is regularly tested and verified by third-party auditors as part of the AWS compliance programs. To learn about the compliance programs that apply to Firewall Manager, see AWS Services in Scope by Compliance Program. • Security in the cloud – Your responsibility is determined by the AWS service that you use. You are also responsible for other factors including the sensitivity of your data, your organization’s requirements, and applicable laws and regulations. This documentation helps you understand how to apply the shared responsibility model when using Firewall Manager. The following topics show you how to configure Firewall Manager to meet your security and compliance objectives. You also learn how to use other AWS services that help you to monitor and secure your Firewall Manager resources. Topics • Data protection in Firewall Manager • Identity and Access Management for AWS Firewall Manager • Logging and monitoring in Firewall Manager • Compliance validation for Firewall Manager • Resilience in Firewall Manager • Infrastructure security in AWS Firewall Manager Data protection in Firewall Manager The AWS shared responsibility model applies to data protection in AWS Firewall Manager. As described in this model, AWS is responsible for protecting the global infrastructure that runs all of the AWS Cloud. You are responsible for maintaining control over your content that is hosted on this infrastructure. You are also responsible for the security configuration and management tasks Data protection 1152 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide for the AWS services that you use. For more information about data privacy, see the Data Privacy FAQ. For information about data protection in Europe, see the AWS Shared Responsibility Model and GDPR blog post on the AWS Security Blog. For data protection purposes, we recommend that you protect AWS account credentials and set up individual users with AWS IAM Identity Center or AWS Identity and Access Management (IAM). That way, each user is given only the permissions necessary to fulfill their job duties. We also recommend that you secure your data in the following ways: • Use multi-factor authentication (MFA) with each account. • Use SSL/TLS to communicate with AWS resources. We require TLS 1.2 and recommend TLS 1.3. • Set up API and user activity logging with AWS CloudTrail. For information about using CloudTrail trails to capture AWS activities, see Working with CloudTrail trails in the AWS CloudTrail User Guide. • Use AWS encryption solutions, along with all default security controls within AWS services. • Use advanced managed security services such as Amazon Macie, which assists in discovering and securing sensitive |

For more information about the available FIPS endpoints, see Federal Information Processing Standard (FIPS) 140-3. We strongly recommend that you never put confidential or sensitive information, such as your customers' email addresses, into tags or free-form text fields such as a Name field. This includes when you work with Firewall Manager or other AWS services using the console, API, AWS CLI, or AWS SDKs. Any data that you enter into tags or free-form text fields used for names may be used for billing or diagnostic logs. If you provide a URL to an external server, we strongly recommend that you do not include credentials information in the URL to validate your request to that server. Firewall Manager entities—such as policies—are encrypted at rest, except in certain Regions where encryption is not available, including China (Beijing) and China (Ningxia). Unique encryption keys are used for each Region. Identity and Access Management for AWS Firewall Manager AWS Identity and Access Management (IAM) is an AWS service that helps an administrator securely control access to AWS resources. IAM administrators control who can be authenticated (signed in) Identity and Access Management 1153 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide and authorized (have permissions) to use Firewall Manager resources. IAM is an AWS service that you can use with no additional charge. Topics • Audience • Authenticating with identities • Managing access using policies • How AWS Firewall Manager works with IAM • Identity-based policy examples for AWS Firewall Manager • AWS managed policies for AWS Firewall Manager • Troubleshooting AWS Firewall Manager identity and access • Using service-linked roles for Firewall Manager • Cross-service confused deputy prevention Audience How you use AWS Identity and Access Management (IAM) differs, depending on the work that you do in Firewall Manager. Service user – If you use the Firewall Manager service to do your job, then your administrator provides you with the credentials and permissions that you need. As you use more Firewall Manager features to do your work, you might need additional permissions. Understanding how access is managed can help you request the right permissions from your administrator. If you cannot access a feature in Firewall Manager, see Troubleshooting AWS Shield identity and access. Service administrator – If you're in charge of Firewall Manager resources at your company, you probably have full access to Firewall Manager. It's your job to determine which Firewall Manager features and resources your service users should access. You must then submit requests to your IAM administrator to change the permissions of your service users. Review the information on this page to understand the basic concepts of IAM. To learn more about how your company can use IAM with Firewall Manager, see How AWS Shield works with IAM. IAM administrator – If you're an IAM administrator, you might want to learn details about how you can write policies to manage access to Firewall Manager. To view example Firewall Manager identity-based policies that you can use in IAM, see Identity-based policy examples for AWS Shield. Identity and Access Management 1154 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Authenticating with identities Authentication is how you sign in to AWS using your identity credentials. You must be authenticated (signed in to AWS) as the AWS account root user, as an IAM user, or by assuming an IAM role. You can sign in to AWS as a federated identity by using credentials provided through an identity source. AWS IAM Identity Center (IAM Identity Center) users, your company's single sign-on authentication, and your Google or Facebook credentials are examples of federated identities. When you sign in as a federated identity, your administrator previously set up identity federation using IAM roles. When you access AWS by using federation, you are indirectly assuming a role. Depending on the type of user you are, you can sign in to the AWS Management Console or the AWS access portal. For more information about signing in to AWS, see How to sign in |
waf-dg-442 | waf-dg.pdf | 442 | federated identity by using credentials provided through an identity source. AWS IAM Identity Center (IAM Identity Center) users, your company's single sign-on authentication, and your Google or Facebook credentials are examples of federated identities. When you sign in as a federated identity, your administrator previously set up identity federation using IAM roles. When you access AWS by using federation, you are indirectly assuming a role. Depending on the type of user you are, you can sign in to the AWS Management Console or the AWS access portal. For more information about signing in to AWS, see How to sign in to your AWS account in the AWS Sign-In User Guide. If you access AWS programmatically, AWS provides a software development kit (SDK) and a command line interface (CLI) to cryptographically sign your requests by using your credentials. If you don't use AWS tools, you must sign requests yourself. For more information about using the recommended method to sign requests yourself, see AWS Signature Version 4 for API requests in the IAM User Guide. Regardless of the authentication method that you use, you might be required to provide additional security information. For example, AWS recommends that you use multi-factor authentication (MFA) to increase the security of your account. To learn more, see Multi-factor authentication in the AWS IAM Identity Center User Guide and AWS Multi-factor authentication in IAM in the IAM User Guide. AWS account root user When you create an AWS account, you begin with one sign-in identity that has complete access to all AWS services and resources in the account. This identity is called the AWS account root user and is accessed by signing in with the email address and password that you used to create the account. We strongly recommend that you don't use the root user for your everyday tasks. Safeguard your root user credentials and use them to perform the tasks that only the root user can perform. For the complete list of tasks that require you to sign in as the root user, see Tasks that require root user credentials in the IAM User Guide. Identity and Access Management 1155 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Federated identity As a best practice, require human users, including users that require administrator access, to use federation with an identity provider to access AWS services by using temporary credentials. A federated identity is a user from your enterprise user directory, a web identity provider, the AWS Directory Service, the Identity Center directory, or any user that accesses AWS services by using credentials provided through an identity source. When federated identities access AWS accounts, they assume roles, and the roles provide temporary credentials. For centralized access management, we recommend that you use AWS IAM Identity Center. You can create users and groups in IAM Identity Center, or you can connect and synchronize to a set of users and groups in your own identity source for use across all your AWS accounts and applications. For information about IAM Identity Center, see What is IAM Identity Center? in the AWS IAM Identity Center User Guide. IAM users and groups An IAM user is an identity within your AWS account that has specific permissions for a single person or application. Where possible, we recommend relying on temporary credentials instead of creating IAM users who have long-term credentials such as passwords and access keys. However, if you have specific use cases that require long-term credentials with IAM users, we recommend that you rotate access keys. For more information, see Rotate access keys regularly for use cases that require long- term credentials in the IAM User Guide. An IAM group is an identity that specifies a collection of IAM users. You can't sign in as a group. You can use groups to specify permissions for multiple users at a time. Groups make permissions easier to manage for large sets of users. For example, you could have a group named IAMAdmins and give that group permissions to administer IAM resources. Users are different from roles. A user is uniquely associated with one person or application, but a role is intended to be assumable by anyone who needs it. Users have permanent long-term credentials, but roles provide temporary credentials. To learn more, see Use cases for IAM users in the IAM User Guide. IAM roles An IAM role is an identity within your AWS account that has specific permissions. It is similar to an IAM user, but is not associated with a specific person. To temporarily assume an IAM role in the AWS Management Console, you can switch from a user to an IAM role (console). You can assume a Identity and Access Management 1156 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide role by calling an AWS |
waf-dg-443 | waf-dg.pdf | 443 | permanent long-term credentials, but roles provide temporary credentials. To learn more, see Use cases for IAM users in the IAM User Guide. IAM roles An IAM role is an identity within your AWS account that has specific permissions. It is similar to an IAM user, but is not associated with a specific person. To temporarily assume an IAM role in the AWS Management Console, you can switch from a user to an IAM role (console). You can assume a Identity and Access Management 1156 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide role by calling an AWS CLI or AWS API operation or by using a custom URL. For more information about methods for using roles, see Methods to assume a role in the IAM User Guide. IAM roles with temporary credentials are useful in the following situations: • Federated user access – To assign permissions to a federated identity, you create a role and define permissions for the role. When a federated identity authenticates, the identity is associated with the role and is granted the permissions that are defined by the role. For information about roles for federation, see Create a role for a third-party identity provider (federation) in the IAM User Guide. If you use IAM Identity Center, you configure a permission set. To control what your identities can access after they authenticate, IAM Identity Center correlates the permission set to a role in IAM. For information about permissions sets, see Permission sets in the AWS IAM Identity Center User Guide. • Temporary IAM user permissions – An IAM user or role can assume an IAM role to temporarily take on different permissions for a specific task. • Cross-account access – You can use an IAM role to allow someone (a trusted principal) in a different account to access resources in your account. Roles are the primary way to grant cross- account access. However, with some AWS services, you can attach a policy directly to a resource (instead of using a role as a proxy). To learn the difference between roles and resource-based policies for cross-account access, see Cross account resource access in IAM in the IAM User Guide. • Cross-service access – Some AWS services use features in other AWS services. For example, when you make a call in a service, it's common for that service to run applications in Amazon EC2 or store objects in Amazon S3. A service might do this using the calling principal's permissions, using a service role, or using a service-linked role. • Forward access sessions (FAS) – When you use an IAM user or role to perform actions in AWS, you are considered a principal. When you use some services, you might perform an action that then initiates another action in a different service. FAS uses the permissions of the principal calling an AWS service, combined with the requesting AWS service to make requests to downstream services. FAS requests are only made when a service receives a request that requires interactions with other AWS services or resources to complete. In this case, you must have permissions to perform both actions. For policy details when making FAS requests, see Forward access sessions. • Service role – A service role is an IAM role that a service assumes to perform actions on your behalf. An IAM administrator can create, modify, and delete a service role from within IAM. For more information, see Create a role to delegate permissions to an AWS service in the IAM User Guide. Identity and Access Management 1157 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • Service-linked role – A service-linked role is a type of service role that is linked to an AWS service. The service can assume the role to perform an action on your behalf. Service-linked roles appear in your AWS account and are owned by the service. An IAM administrator can view, but not edit the permissions for service-linked roles. • Applications running on Amazon EC2 – You can use an IAM role to manage temporary credentials for applications that are running on an EC2 instance and making AWS CLI or AWS API requests. This is preferable to storing access keys within the EC2 instance. To assign an AWS role to an EC2 instance and make it available to all of its applications, you create an instance profile that is attached to the instance. An instance profile contains the role and enables programs that are running on the EC2 instance to get temporary credentials. For more information, see Use an IAM role to grant permissions to applications running on Amazon EC2 instances in the IAM User Guide. Managing access using policies You control access in AWS by creating policies and attaching them to AWS identities or resources. A |

To assign an AWS role to an EC2 instance and make it available to all of its applications, you create an instance profile that is attached to the instance. An instance profile contains the role and enables programs that are running on the EC2 instance to get temporary credentials. For more information, see Use an IAM role to grant permissions to applications running on Amazon EC2 instances in the IAM User Guide. Managing access using policies You control access in AWS by creating policies and attaching them to AWS identities or resources. A policy is an object in AWS that, when associated with an identity or resource, defines their permissions. AWS evaluates these policies when a principal (user, root user, or role session) makes a request. Permissions in the policies determine whether the request is allowed or denied. Most policies are stored in AWS as JSON documents. For more information about the structure and contents of JSON policy documents, see Overview of JSON policies in the IAM User Guide. Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions. By default, users and roles have no permissions. To grant users permission to perform actions on the resources that they need, an IAM administrator can create IAM policies. The administrator can then add the IAM policies to roles, and users can assume the roles. IAM policies define permissions for an action regardless of the method that you use to perform the operation. For example, suppose that you have a policy that allows the iam:GetRole action. A user with that policy can get role information from the AWS Management Console, the AWS CLI, or the AWS API. Identity-based policies Identity-based policies are JSON permissions policy documents that you can attach to an identity, such as an IAM user, group of users, or role. These policies control what actions users and roles can Identity and Access Management 1158 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see Define custom IAM permissions with customer managed policies in the IAM User Guide. Identity-based policies can be further categorized as inline policies or managed policies. Inline policies are embedded directly into a single user, group, or role. Managed policies are standalone policies that you can attach to multiple users, groups, and roles in your AWS account. Managed policies include AWS managed policies and customer managed policies. To learn how to choose between a managed policy or an inline policy, see Choose between managed policies and inline policies in the IAM User Guide. Resource-based policies Resource-based policies are JSON policy documents that you attach to a resource. Examples of resource-based policies are IAM role trust policies and Amazon S3 bucket policies. In services that support resource-based policies, service administrators can use them to control access to a specific resource. For the resource where the policy is attached, the policy defines what actions a specified principal can perform on that resource and under what conditions. You must specify a principal in a resource-based policy. Principals can include accounts, users, roles, federated users, or AWS services. Resource-based policies are inline policies that are located in that service. You can't use AWS managed policies from IAM in a resource-based policy. Access control lists (ACLs) Access control lists (ACLs) control which principals (account members, users, or roles) have permissions to access a resource. ACLs are similar to resource-based policies, although they do not use the JSON policy document format. Amazon S3, AWS WAF, and Amazon VPC are examples of services that support ACLs. To learn more about ACLs, see Access control list (ACL) overview in the Amazon Simple Storage Service Developer Guide. Other policy types AWS supports additional, less-common policy types. These policy types can set the maximum permissions granted to you by the more common policy types. • Permissions boundaries – A permissions boundary is an advanced feature in which you set the maximum permissions that an identity-based policy can grant to an IAM entity (IAM user Identity and Access Management 1159 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide or role). You can set a permissions boundary for an entity. The resulting permissions are the intersection of an entity's identity-based policies and its permissions boundaries. Resource-based policies that specify the user or role in the Principal field are not limited by the permissions boundary. An explicit deny in any of these policies overrides the allow. For more information about permissions boundaries, see Permissions boundaries for IAM entities in the IAM User Guide. • Service control policies (SCPs) – SCPs are JSON policies that |

The resulting permissions are the intersection of an entity's identity-based policies and its permissions boundaries. Resource-based policies that specify the user or role in the Principal field are not limited by the permissions boundary. An explicit deny in any of these policies overrides the allow. For more information about permissions boundaries, see Permissions boundaries for IAM entities in the IAM User Guide. • Service control policies (SCPs) – SCPs are JSON policies that specify the maximum permissions for an organization or organizational unit (OU) in AWS Organizations. AWS Organizations is a service for grouping and centrally managing multiple AWS accounts that your business owns. If you enable all features in an organization, then you can apply service control policies (SCPs) to any or all of your accounts. The SCP limits permissions for entities in member accounts, including each AWS account root user. For more information about Organizations and SCPs, see Service control policies in the AWS Organizations User Guide. • Resource control policies (RCPs) – RCPs are JSON policies that you can use to set the maximum available permissions for resources in your accounts without updating the IAM policies attached to each resource that you own. The RCP limits permissions for resources in member accounts and can impact the effective permissions for identities, including the AWS account root user, regardless of whether they belong to your organization. For more information about Organizations and RCPs, including a list of AWS services that support RCPs, see Resource control policies (RCPs) in the AWS Organizations User Guide. • Session policies – Session policies are advanced policies that you pass as a parameter when you programmatically create a temporary session for a role or federated user. The resulting session's permissions are the intersection of the user or role's identity-based policies and the session policies. Permissions can also come from a resource-based policy. An explicit deny in any of these policies overrides the allow. For more information, see Session policies in the IAM User Guide. Multiple policy types When multiple types of policies apply to a request, the resulting permissions are more complicated to understand. To learn how AWS determines whether to allow a request when multiple policy types are involved, see Policy evaluation logic in the IAM User Guide.

Identity-based policies for Firewall Manager Supports identity-based policies: Yes Identity-based policies are JSON permissions policy documents that you can attach to an identity, such as an IAM user, group of users, or role. These policies control what actions users and roles can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see Define custom IAM permissions with customer managed policies in the IAM User Guide. With IAM identity-based policies, you can specify allowed or denied actions and resources as well as the conditions under which actions are allowed or denied. You can't specify the principal in an identity-based policy because it applies to the user or role to which it is attached. To learn about all Identity and Access Management 1161 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide of the elements that you can use in a JSON policy, see IAM JSON policy elements reference in the IAM User Guide.

Resource-based policies within Firewall Manager Supports resource-based policies: No Resource-based policies are JSON policy documents that you attach to a resource. Examples of resource-based policies are IAM role trust policies and Amazon S3 bucket policies. In services that support resource-based policies, service administrators can use them to control access to a specific resource. For the resource where the policy is attached, the policy defines what actions a specified principal can perform on that resource and under what conditions. You must specify a principal in a resource-based policy. Principals can include accounts, users, roles, federated users, or AWS services. To enable cross-account access, you can specify an entire account or IAM entities in another account as the principal in a resource-based policy. Adding a cross-account principal to a resource- based policy is only half of establishing the trust relationship. When the principal and the resource are in different AWS accounts, an IAM administrator in the trusted account must also grant the principal entity (user or role) permission to access the resource. They grant permission by attaching an identity-based policy to the entity. However, if a resource-based policy grants access to a principal in the same account, no additional identity-based policy is required. For more information, see Cross account resource access in IAM in the IAM User Guide. Policy actions for Firewall Manager Supports policy actions: Yes Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions. The Action element of a JSON policy describes the actions that you can use to allow or deny access in a policy. Policy actions usually have the same name as the associated AWS API operation. Identity and Access Management 1162 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide There are some exceptions, such as permission-only actions that don't have a matching API operation. There are also some operations that require multiple actions in a policy. These additional actions are called dependent actions. Include actions in a policy to grant permissions to perform the associated operation. To see a list of Firewall Manager actions, see Actions defined by AWS Firewall Manager in the Service Authorization Reference. Policy actions in Firewall Manager use the following prefix before the action: fms To specify multiple actions in a single statement, separate them with commas. "Action": [ "fms:action1", "fms:action2" ] You can specify multiple actions using wildcards (*). For example, to specify all actions that begin with the word Describe, include the following action: "Action": "fms:Describe*" To view examples of Firewall Manager identity-based policies, see Identity-based policy examples for AWS Firewall Manager. Policy resources for Firewall Manager Supports policy resources: Yes Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions. The Resource JSON policy element specifies the object or objects to which the action applies. Statements must include either a Resource or a NotResource element. As a best practice, Identity and Access Management 1163 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide specify a resource using its Amazon Resource Name (ARN). You can do this for actions that support a specific resource type, known as resource-level permissions. For actions that don't support resource-level permissions, such as listing operations, use a wildcard (*) to indicate that the statement applies to all resources. "Resource": "*" To see a list of Firewall Manager resource types and their ARNs, see Resources defined by AWS Firewall Manager in the Service Authorization Reference. To learn with which actions you can specify the ARN of each resource, see Actions defined by AWS Firewall Manager. To view examples of Firewall Manager identity-based policies, see Identity-based policy examples for AWS Firewall Manager. Policy condition keys for Firewall Manager Supports service-specific policy condition keys: No Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions. The Condition element (or Condition block) lets you specify conditions in which a statement is in effect. The Condition element is optional. You can create conditional expressions that use condition operators, such as equals or less than, to match the condition in the policy with values in the request. If you specify multiple Condition elements in a statement, or multiple keys in a single Condition element, AWS evaluates them using a logical AND operation. If you specify multiple values for a single condition key, AWS evaluates the condition using a logical OR operation. All of the conditions must be met |

ACLs are similar to resource-based policies, although they do not use the JSON policy document format. ABAC with Firewall Manager Supports ABAC (tags in policies): Yes Attribute-based access control (ABAC) is an authorization strategy that defines permissions based on attributes. In AWS, these attributes are called tags. You can attach tags to IAM entities (users or roles) and to many AWS resources. Tagging entities and resources is the first step of ABAC. Then you design ABAC policies to allow operations when the principal's tag matches the tag on the resource that they are trying to access. ABAC is helpful in environments that are growing rapidly and helps with situations where policy management becomes cumbersome. To control access based on tags, you provide tag information in the condition element of a policy using the aws:ResourceTag/key-name, aws:RequestTag/key-name, or aws:TagKeys condition keys. If a service supports all three condition keys for every resource type, then the value is Yes for the service. If a service supports all three condition keys for only some resource types, then the value is Partial. For more information about ABAC, see Define permissions with ABAC authorization in the IAM User Guide. To view a tutorial with steps for setting up ABAC, see Use attribute-based access control (ABAC) in the IAM User Guide. Using temporary credentials with Firewall Manager Supports temporary credentials: Yes Identity and Access Management 1165 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Some AWS services don't work when you sign in using temporary credentials. For additional information, including which AWS services work with temporary credentials, see AWS services that work with IAM in the IAM User Guide. You are using temporary credentials if you sign in to the AWS Management Console using any method except a user name and password. For example, when you access AWS using your company's single sign-on (SSO) link, that process automatically creates temporary credentials. You also automatically create temporary credentials when you sign in to the console as a user and then switch roles. For more information about switching roles, see Switch from a user to an IAM role (console) in the IAM User Guide. You can manually create temporary credentials using the AWS CLI or AWS API. You can then use those temporary credentials to access AWS. AWS recommends that you dynamically generate temporary credentials instead of using long-term access keys. For more information, see Temporary security credentials in IAM. Forward access sessions for Firewall Manager Supports forward access sessions (FAS): Yes When you use an IAM user or role to perform actions in AWS, you are considered a principal. When you use some services, you might perform an action that then initiates another action in a different service. FAS uses the permissions of the principal calling an AWS service, combined with the requesting AWS service to make requests to downstream services. FAS requests are only made when a service receives a request that requires interactions with other AWS services or resources to complete. In this case, you must have permissions to perform both actions. For policy details when making FAS requests, see Forward access sessions. Service |

FAS requests are only made when a service receives a request that requires interactions with other AWS services or resources to complete. In this case, you must have permissions to perform both actions. For policy details when making FAS requests, see Forward access sessions. Service roles for Firewall Manager Supports service roles: Partial A service role is an IAM role that a service assumes to perform actions on your behalf. An IAM administrator can create, modify, and delete a service role from within IAM. For more information, see Create a role to delegate permissions to an AWS service in the IAM User Guide. Warning Changing the permissions for a service role might break Firewall Manager functionality. Edit service roles only when Firewall Manager provides guidance to do so. Identity and Access Management 1166 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Choosing an IAM role in Firewall Manager To use the PutNotificationChannel API action in Firewall Manager, you must choose a role to allow Firewall Manager to access Amazon SNS so that the service can publish Amazon SNS messages on your behalf. For more information, see PutNotificationChannel in the AWS Firewall Manager API Reference. The following shows an example SNS topic permission setting. To use this policy with your own custom role, replace the replace the AWSServiceRoleForFMS Amazon Resource Name (ARN) with the SnsRoleName ARN. { "Sid": "AWSFirewallManagerSNSPolicy", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::account ID:role/aws-service-role/ fms.amazonaws.com/AWSServiceRoleForFMS" }, "Action": "sns:Publish", "Resource": "SNS topic ARN" } For more information about Firewall Manager actions and resources, see the AWS Identity and Access Management guide topic Actions Defined by AWS Firewall Manager Service-linked roles for Firewall Manager Supports service-linked roles: Yes A service-linked role is a type of service role that is linked to an AWS service. The service can assume the role to perform an action on your behalf. Service-linked roles appear in your AWS account and are owned by the service. An IAM administrator can view, but not edit the permissions for service-linked roles. For details about creating or managing service-linked roles, see AWS services that work with IAM. Find a service in the table that includes a Yes in the Service-linked role column. Choose the Yes link to view the service-linked role documentation for that service. Identity-based policy examples for AWS Firewall Manager By default, users and roles don't have permission to create or modify Firewall Manager resources. They also can't perform tasks by using the AWS Management Console, AWS Command Line Identity and Access Management 1167 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Interface (AWS CLI), or AWS API. To grant users permission to perform actions on the resources that they need, an IAM administrator can create IAM policies. The administrator can then add the IAM policies to roles, and users can assume the roles. To learn how to create an IAM identity-based policy by using these example JSON policy documents, see Create IAM policies (console) in the IAM User Guide. For details about actions and resource types defined by Firewall Manager, including the format of the ARNs for each of the resource types, see Actions, resources, and condition keys for AWS Firewall Manager in the Service Authorization Reference. Topics • Policy best practices • Using the Firewall Manager console • Allow users to view their own permissions • Grant read access to your Firewall Manager security groups Policy best practices Identity-based policies determine whether someone can create, access, or delete Firewall Manager resources in your account. These actions can incur costs for your AWS account. When you create or edit identity-based policies, follow these guidelines and recommendations: • Get started with AWS managed policies and move toward least-privilege permissions – To get started granting permissions to your users and workloads, use the AWS managed policies that grant permissions for many common use cases. They are available in your AWS account. We recommend that you reduce permissions further by defining AWS customer managed policies that are specific to your use cases. For more information, see AWS managed policies or AWS managed policies for job functions in the IAM User Guide. • Apply least-privilege permissions – When you set permissions with IAM policies, grant only the permissions required to perform a task. You do this by defining the actions that can be taken on specific resources under specific conditions, also known as least-privilege permissions. For more information about using IAM to apply permissions, see Policies and permissions in IAM |
waf-dg-449 | waf-dg.pdf | 449 | your AWS account. We recommend that you reduce permissions further by defining AWS customer managed policies that are specific to your use cases. For more information, see AWS managed policies or AWS managed policies for job functions in the IAM User Guide. • Apply least-privilege permissions – When you set permissions with IAM policies, grant only the permissions required to perform a task. You do this by defining the actions that can be taken on specific resources under specific conditions, also known as least-privilege permissions. For more information about using IAM to apply permissions, see Policies and permissions in IAM in the IAM User Guide. • Use conditions in IAM policies to further restrict access – You can add a condition to your policies to limit access to actions and resources. For example, you can write a policy condition to specify that all requests must be sent using SSL. You can also use conditions to grant access to Identity and Access Management 1168 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide service actions if they are used through a specific AWS service, such as AWS CloudFormation. For more information, see IAM JSON policy elements: Condition in the IAM User Guide. • Use IAM Access Analyzer to validate your IAM policies to ensure secure and functional permissions – IAM Access Analyzer validates new and existing policies so that the policies adhere to the IAM policy language (JSON) and IAM best practices. IAM Access Analyzer provides more than 100 policy checks and actionable recommendations to help you author secure and functional policies. For more information, see Validate policies with IAM Access Analyzer in the IAM User Guide. • Require multi-factor authentication (MFA) – If you have a scenario that requires IAM users or a root user in your AWS account, turn on MFA for additional security. To require MFA when API operations are called, add MFA conditions to your policies. For more information, see Secure API access with MFA in the IAM User Guide. For more information about best practices in IAM, see Security best practices in IAM in the IAM User Guide. Using the Firewall Manager console To access the AWS Firewall Manager console, you must have a minimum set of permissions. These permissions must allow you to list and view details about the Firewall Manager resources in your AWS account. If you create an identity-based policy that is more restrictive than the minimum required permissions, the console won't function as intended for entities (users or roles) with that policy. You don't need to allow minimum console permissions for users that are making calls only to the AWS CLI or the AWS API. Instead, allow access to only the actions that match the API operation that they're trying to perform. To ensure that users and roles can still use the Firewall Manager console, also attach the Firewall Manager ConsoleAccess or ReadOnly AWS managed policy to the entities. For more information, see Adding permissions to a user in the IAM User Guide. Allow users to view their own permissions This example shows how you might create a policy that allows IAM users to view the inline and managed policies that are attached to their user identity. This policy includes permissions to complete this action on the console or programmatically using the AWS CLI or AWS API. { Identity and Access Management 1169 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide "Version": "2012-10-17", "Statement": [ { "Sid": "ViewOwnUserInfo", "Effect": "Allow", "Action": [ "iam:GetUserPolicy", "iam:ListGroupsForUser", "iam:ListAttachedUserPolicies", "iam:ListUserPolicies", "iam:GetUser" ], "Resource": ["arn:aws:iam::*:user/${aws:username}"] }, { "Sid": "NavigateInConsole", "Effect": "Allow", "Action": [ "iam:GetGroupPolicy", "iam:GetPolicyVersion", "iam:GetPolicy", "iam:ListAttachedGroupPolicies", "iam:ListGroupPolicies", "iam:ListPolicyVersions", "iam:ListPolicies", "iam:ListUsers" ], "Resource": "*" } ] } Grant read access to your Firewall Manager security groups Firewall Manager allows cross-account resource access, but it doesn't allow you to create cross- account resource protections. You can only create protections for resources from within the account that owns those resources. The following is an example policy that grants permissions for the fms:Get,fms:List, and ec2:DescribeSecurityGroups actions on all resources. { "Version": "2012-10-17", Identity and Access Management 1170 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide "Statement": [ { "Action": [ "fms:Get*", "fms:List*", "ec2:DescribeSecurityGroups" ], "Effect": "Allow", "Resource": "*" } ] } AWS managed policies for AWS Firewall Manager An AWS managed policy is a standalone policy that is created and administered by AWS. AWS managed policies are designed to provide permissions for many common use cases so that you can start assigning permissions to users, groups, and roles. Keep in mind that AWS managed policies might not grant least-privilege permissions for your specific use cases because they're available for all AWS customers to use.

Troubleshooting AWS Firewall Manager identity and access Use the following information to help you diagnose and fix common issues that you might encounter when working with Firewall Manager and IAM. Topics • I am not authorized to perform an action in Firewall Manager • I am not authorized to perform iam:PassRole • I want to allow people outside of my AWS account to access my Firewall Manager resources Identity and Access Management 1179 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide I am not authorized to perform an action in Firewall Manager If you receive an error that you're not authorized to perform an action, your policies must be updated to allow you to perform the action. The following example error occurs when the mateojackson IAM user tries to use the console to view details about a fictional my-example-widget resource but doesn't have the fictional fms:GetWidget permissions. User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: fms:GetWidget on resource: my-example-widget In this case, the policy for the mateojackson user must be updated to allow access to the my- example-widget resource by using the fms:GetWidget action. If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials. I am not authorized to perform iam:PassRole If you receive an error that you're not authorized to perform the iam:PassRole action, your policies must be updated to allow you to pass a role to Firewall Manager. Some AWS services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. To do this, you must have permissions to pass the role to the service. The following example error occurs when an IAM user named marymajor tries to use the console to perform an action in Firewall Manager. However, the action requires the service to have permissions that are granted by a service role. Mary does not have permissions to pass the role to the service. User: arn:aws:iam::123456789012:user/marymajor is not authorized to perform: iam:PassRole In this case, Mary's policies must be updated to allow her to perform the iam:PassRole action. If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials. Identity and Access Management 1180 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide I want to allow people outside of my AWS account to access my Firewall Manager resources You can create a role that users in other accounts or people outside of your organization can use to access your resources. You can specify who is trusted to assume the role. For services that support resource-based policies or access control lists (ACLs), you can use those policies to grant people access to your resources.

Using service-linked roles for Firewall Manager AWS Firewall Manager uses AWS Identity and Access Management (IAM) service-linked roles. A service-linked role is a unique type of IAM role that is linked directly to Firewall Manager. Service- linked roles are predefined by Firewall Manager and include all the permissions that the service requires to call other AWS services on your behalf. A service-linked role makes setting up Firewall Manager easier because you don’t have to manually add the necessary permissions. Firewall Manager defines the permissions of its service-linked roles, and unless defined otherwise, only Firewall Manager can assume its roles. The defined permissions include the trust policy and the permissions policy. That permissions policy can't be attached to any other IAM entity. You can delete a service-linked role only after first deleting the role's related resources. This protects your Firewall Manager resources because you can't inadvertently remove permission to access the resources. Identity and Access Management 1181 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide For information about other services that support service-linked roles, see AWS Services That Work with IAM and look for the services that have Yes in the Service-Linked Role column. Choose a Yes with a link to view the service-linked role documentation for that service. Service-linked role permissions for Firewall Manager AWS Firewall Manager uses the service-linked role name AWSServiceRoleForFMS to allow Firewall Manager to call AWS services on your behalf for management of firewall policies and AWS Organizations account resources. This policy is attached to the AWS managed role AWSServiceRoleForFMS. For more information about the managed role, see AWS managed policy: FMSServiceRolePolicy. The AWSServiceRoleForFMS service-linked role trusts the service to assume the role fms.amazonaws.com. The role permissions policy allows Firewall Manager to complete the following actions on the specified resources: • waf - Manage AWS WAF Classic web ACLs, rule group permissions, and the web ACLs associations in your account. • ec2 - Manage security groups on elastic network interfaces and Amazon EC2 instances. Manage network ACLs on Amazon VPC subnets. • vpc - Manage subnets, route tables, tags, and endpoints in Amazon VPC. • wafv2 - Manage AWS WAF web ACLs, rule group permissions, and the web ACLs associations in your account. • cloudfront - Create web ACLs to protect CloudFront distributions. • config - Manage Firewall Manager-owned AWS Config rules in your account. • iam - Manage this service-linked role, and creates required AWS WAF and Shield service-linked roles if configuring logging for AWS WAF and Shield policies. • organization - Create a service-linked role owned by Firewall Manager to manage AWS Organizations resources used by Firewall Manager. • shield - Manage AWS Shield protections and L7 mitigation configurations for resources in your account. • ram - Manage AWS RAM resource sharing for DNS Firewall rule groups and Network Firewall rule groups. Identity and Access Management 1182 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • network-firewall - Manage Firewall Manager-owned AWS Network Firewall resources and dependent Amazon VPC resources in your account. • route53resolver - Manage Firewall Manager-owned DNS Firewall associations in your account. See the full policy in the IAM console: FMSServiceRolePolicy. You must configure permissions to allow an IAM entity (such as a user, group, or role) to create, edit, or delete a service-linked role. For more information, see Service-Linked Role Permissions in the IAM User Guide. Creating a service-linked role for Firewall Manager You don't need to manually create a service-linked role. When you enable Firewall Manager logging on the AWS Management Console, or you make a PutLoggingConfiguration request in the Firewall Manager CLI or the Firewall Manager API, Firewall Manager creates the service-linked role for you. You must have the iam:CreateServiceLinkedRole permission to enable logging. If you delete this service-linked role, and then need to create it again, you can use the same process to recreate the role in your account. When you enable Firewall Manager logging, Firewall Manager creates the service-linked role for you again.

If you delete this service-linked role, and then need to create it again, you can use the same process to recreate the role in your account. When you enable Firewall Manager logging, Firewall Manager creates the service-linked role for you again. Editing a service-linked role for Firewall Manager Firewall Manager doesn't allow you to edit the AWSServiceRoleForFMS service-linked role. After you create a service-linked role, you can't change the name of the role because various entities might reference the role. However, you can edit the description of the role using IAM. For more information, see Editing a Service-Linked Role in the IAM User Guide. Deleting a service-linked role for Firewall Manager If you no longer need to use a feature or service that requires a service-linked role, we recommend that you delete that role. That way you don’t have an unused entity that is not actively monitored or maintained. However, you must clean up the resources for your service-linked role before you can manually delete it. Identity and Access Management 1183 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Note If the Firewall Manager service is using the role when you try to delete the resources, then the deletion might fail. If that happens, wait for a few minutes and try the operation again. To delete the service-linked role using IAM Use the IAM console, the IAM CLI, or the IAM API to delete the AWSServiceRoleForFMS service- linked role. For more information, see Deleting a Service-Linked Role in the IAM User Guide. Supported Regions for Firewall Manager service-linked roles Firewall Manager supports using service-linked roles in all of the regions where the service is available. For more information, see Firewall Manager endpoints and quotas. Cross-service confused deputy prevention The confused deputy problem is a security issue where an entity that doesn't have permission to perform an action can coerce a more-privileged entity to perform the action. In AWS, cross-service impersonation can result in the confused deputy problem. Cross-service impersonation can occur when one service (the calling service) calls another service (the called service). The calling service can be manipulated to use its permissions to act on another customer's resources in a way it should not otherwise have permission to access. To prevent this, AWS provides tools that help you protect your data for all services with service principals that have been given access to resources in your account. We recommend using the aws:SourceArn and aws:SourceAccount global condition context keys in resource policies to limit the permissions that AWS Firewall Manager gives another service to the resource. Use aws:SourceArn if you want only one resource to be associated with the cross-service access. Use aws:SourceAccount if you want to allow any resource in that account to be associated with the cross-service use. The most effective way to protect against the confused deputy problem is to use the aws:SourceArn global condition context key with the full ARN of the resource. If you don't know the full ARN of the resource or if you are specifying multiple resources, use the aws:SourceArn global context condition key with wildcard characters (*) for the unknown portions of the ARN. For example, arn:aws:fms:*:account-id:*. Identity and Access Management 1184 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide If the aws:SourceArn value does not contain the account ID, such as an Amazon S3 bucket ARN, you must use both global condition context keys to limit permissions. The value of aws:SourceArn must be the AWS Firewall Manager administrator's AWS account. The following examples show how you can use the aws:SourceArn global condition context key in Firewall Manager to prevent the confused deputy problem. The following example shows how to prevent the confused deputy problem by using the aws:SourceArn global condition context key in the Firewall Manager role trust policy.

AWS provides several tools for monitoring your Firewall Manager resources and responding to potential events: Amazon CloudWatch Alarms Using CloudWatch alarms, you watch a single metric over a time period that you specify. If the metric exceeds a given threshold, CloudWatch sends a notification to an Amazon SNS topic or AWS Auto Scaling policy. For more information, see Monitoring with Amazon CloudWatch. AWS CloudTrail Logs CloudTrail provides a record of actions taken by a user, role, or an AWS service in Firewall Manager. Using the information collected by CloudTrail, you can determine the request that was made to Firewall Manager, the IP address from which the request was made, who made the request, when it was made, and additional details. For more information, see Logging API calls with AWS CloudTrail. Logging and monitoring 1186 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Compliance validation for Firewall Manager To learn whether an AWS service is within the scope of specific compliance programs, see AWS services in Scope by Compliance Program and choose the compliance program that you are interested in. For general information, see AWS Compliance Programs. You can download third-party audit reports using AWS Artifact. For more information, see Downloading Reports in AWS Artifact. Your compliance responsibility when using AWS services is determined by the sensitivity of your data, your company's compliance objectives, and applicable laws and regulations. AWS provides the following resources to help with compliance: • Security Compliance & Governance – These solution implementation guides discuss architectural considerations and provide steps for deploying security and compliance features. • HIPAA Eligible Services Reference – Lists HIPAA eligible services. Not all AWS services are HIPAA eligible. • AWS Compliance Resources – This collection of workbooks and guides might apply to your industry and location. • AWS Customer Compliance Guides – Understand the shared responsibility model through the lens of compliance. The guides summarize the best practices for securing AWS services and map the guidance to security controls across multiple frameworks (including National Institute of Standards and Technology (NIST), Payment Card Industry Security Standards Council (PCI), and International Organization for Standardization (ISO)). • Evaluating Resources with Rules in the AWS Config Developer Guide – The AWS Config service assesses how well your resource configurations comply with internal practices, industry guidelines, and regulations. • AWS Security Hub – This AWS service provides a comprehensive view of your security state within AWS. Security Hub uses security controls to evaluate your AWS resources and to check your compliance against security industry standards and best practices. For a list of supported services and controls, see Security Hub controls reference. • Amazon GuardDuty – This AWS service detects potential threats to your AWS accounts, workloads, containers, and data by monitoring your environment for suspicious and malicious activities.

Resilience in Firewall Manager The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between Availability Zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures. For more information about AWS Regions and Availability Zones, see AWS Global Infrastructure. Infrastructure security in AWS Firewall Manager As a managed service, AWS Firewall Manager is protected by AWS global network security. For information about AWS security services and how AWS protects infrastructure, see AWS Cloud Security. To design your AWS environment using the best practices for infrastructure security, see Infrastructure Protection in Security Pillar AWS Well‐Architected Framework. You use AWS published API calls to access Firewall Manager through the network. Clients must support the following: • Transport Layer Security (TLS).

Or you can use the AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests. AWS Firewall Manager quotas AWS Firewall Manager is subject to the following quotas (formerly referred to as limits). AWS Firewall Manager has default quotas that you might be able to increase and fixed quotas. Resilience 1188 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide The security group policies and network ACL policies that are managed by Firewall Manager are subject to standard Amazon VPC quotas. For more information, see Amazon VPC Quotas in the Amazon VPC User Guide. Each Firewall Manager Network Firewall policy creates a Network Firewall firewall with an associated firewall policy and its rule groups. These Network Firewall resources are subject to the quotas listed at AWS Network Firewall quotas in the Network Firewall Developer Guide. Soft quotas AWS Firewall Manager has default quotas on the number of entities per Region. You can request an increase in these quotas. All policy types Resource Accounts per organization in AWS Organizations Firewall Manager policies per organization in AWS Organizations. Default quota per Region Varies. An invitatio n sent to an account counts against this quota. The count is returned if the invited account declines, the management account cancels the invitatio n, or the invitation expires. 50.

Note For information about monitoring your Shield Advanced resources and identifying possible DDoS events using Shield Advanced, see AWS Shield. As you start monitoring these services, you should create a monitoring plan that includes answers to the following questions: • What are your monitoring goals? • What resources will you monitor? • How often will you monitor these resources? • What monitoring tools will you use? • Who will perform the monitoring tasks? • Who should be notified when something goes wrong? The next step is to establish a baseline for normal performance in your environment, by measuring performance at various times and under different load conditions. As you monitor AWS WAF, Firewall Manager, Shield Advanced and related services, store historical monitoring data so that you can compare it with current performance data, identify normal performance patterns and performance anomalies, and devise methods to address issues. For AWS WAF, you should monitor the following items at a minimum to establish a baseline: • The number of allowed web requests • The number of blocked web requests Topics • Monitoring tools 1194 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • Monitoring with Amazon CloudWatch • Logging API calls with AWS CloudTrail Monitoring tools AWS provides various tools that you can use to monitor AWS WAF and AWS Shield Advanced. You can configure some of these tools to do the monitoring for you, while other tools require manual intervention. We recommend that you automate monitoring tasks as much as possible. Automated monitoring tools You can use the following automated monitoring tools to watch AWS WAF and AWS Shield Advanced and report when something is wrong: • Web ACL traffic overview dashboards – Access summaries of the web traffic that a web ACL evaluates by going to the web ACL's page in the AWS WAF console and opening the Traffic overview tab. The traffic overview dashboards provide near real-time summaries of the Amazon CloudWatch metrics that AWS WAF collects when it evaluates your application web traffic. You can see summaries for all of your web traffic and for traffic evaluated by the intelligent threat mitigation rule groups. For more information, see Web ACL traffic overview dashboards or go to the dashboards in the console. • Amazon CloudWatch Alarms – Watch a single metric over a time period you specify, and perform one or more actions based on the value of the metric relative to a given threshold over a number of time periods. The action is a notification sent to an Amazon Simple Notification Service (Amazon SNS) topic or Amazon EC2 Auto Scaling policy. Alarms invoke actions for sustained state changes only.

For more information, see Monitoring CloudFront Activity Using CloudWatch. Note CloudWatch metrics and alarms are not enabled for AWS Firewall Manager. Monitoring tools 1195 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Not only can you use CloudWatch to monitor AWS WAF and Shield Advanced metrics as described in Monitoring with Amazon CloudWatch, you also should use CloudWatch to monitor activity for your protected resources. For more information, see the following: • Monitoring CloudFront Activity Using CloudWatch in the Amazon CloudFront Developer Guide • Logging and monitoring in Amazon API Gateway in the API Gateway Developer Guide • CloudWatch Metrics for Your Application Load Balancer in the Elastic Load Balancing User Guide • Monitoring and Logging in the AWS AppSync Developer Guide • Logging and monitoring in Amazon Cognito in the Amazon Cognito Developer Guide • Viewing App Runner logs streamed to CloudWatch Logs and Viewing App Runner service metrics reported to CloudWatch in the AWS App Runner Developer Guide • Amazon CloudWatch Logs – Monitor, store, and access your log files from AWS CloudTrail or other sources. For more information, see What is Amazon CloudWatch Logs?. • Amazon CloudWatch Events – Automate your AWS services and respond automatically to system events. Events from AWS services are delivered to CloudWatch Events in near real time, and you can specify automated actions to take when an event matches a rule that you write. For more information, see What is Amazon CloudWatch Events? • AWS CloudTrail Log Monitoring – Share log files between accounts, monitor CloudTrail log files in real time by sending them to CloudWatch Logs, write log-processing applications in Java, and validate that your log files have not changed after delivery by CloudTrail. For more information, see Logging API calls with AWS CloudTrail and Working with CloudTrail Log Files in the AWS CloudTrail User Guide. • AWS Config – View the configuration of AWS resources in your AWS account, including how the resources are related to one another and how they were configured in the past so that you can see how the configurations and relationships change over time. Manual monitoring tools Another important part of monitoring AWS WAF and AWS Shield Advanced involves manually monitoring those items that the CloudWatch alarms don't cover. You can view the AWS WAF, Shield Advanced, CloudWatch, and other AWS Management Console dashboards to see the state of your AWS environment. We recommend that you also check the log files for your web ACLs and rules. Manual tools 1196 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • For example, to view the AWS WAF dashboard: • On the Requests tab of the AWS WAF Web ACLs page, view a graph of total requests and requests that match each rule that you have created. For more information, see Viewing a sample of web requests. • View the CloudWatch home page for the following: • Current alarms and status • Graphs of alarms and resources • Service health status In addition, you can use CloudWatch to do the following: • Create customized dashboards to monitor the services that you care about. • Graph metric data to troubleshoot issues and discover trends. • Search and browse all of your AWS resource metrics. • Create and edit alarms to be notified of problems. Monitoring with Amazon CloudWatch You can monitor web requests and web ACLs and rules using Amazon CloudWatch, which collects and processes raw data from AWS WAF and AWS Shield Advanced into readable, near real-time metrics. You can use statistics in Amazon CloudWatch to gain a perspective on how your web application or service is performing. For more information, see What is CloudWatch in the Amazon CloudWatch User Guide. Note CloudWatch metrics and alarms are not enabled for Firewall Manager.

AWS WAF provides metrics and dimensions in the AWS/ WAFV2 namespace. You can see summary information for AWS WAF metrics through the AWS WAF console, in the web ACL's traffic overview tab. For more information, go to the console or see Web ACL traffic overview dashboards. You can see the following metrics for web ACLs, rules, rule groups, and labels. • Your rules – Metrics are grouped by the rule action. For example, when you test a rule in Count mode, its matches are listed as Count metrics for the web ACL. • Your rule groups – The metrics for your rule groups are listed under the rule group metrics. • Rule groups owned by another account – Rule group metrics are generally visible only to the rule group owner. However, if you override the rule action for a rule, the metrics for that rule will be listed under your web ACL metrics. Additionally, labels added by any rule group are listed in your web ACL metrics Rule groups in this category are AWS Managed Rules for AWS WAF, AWS Marketplace rule groups, Recognizing rule groups provided by other services, and rule groups that are shared with you by another account. • Labels - Labels that were added to a web request during evaluation are listed in the web ACL label metrics. You can access the metrics for all labels, regardless of whether they were added by your rules and rule groups or by rules in a rule group that another account owns.

AWS Shield Advanced metrics Shield Advanced publishes Amazon CloudWatch detection, mitigation, and top contributor metrics for all resources that it protects. These metrics improve your ability to monitor your resources by making it possible to create and configure CloudWatch dashboards and alarms for them. The Shield Advanced console presents summaries of many of the metrics that it records. For information, see Visibility into DDoS events with Shield Advanced. If you enable automatic application layer DDoS mitigation for an application layer protection, Shield Advanced adds a rule group to your web ACL that it uses to manage automated protections. This rule group generates AWS WAF metrics, but they are not available to view. This is the same as for any other rule groups that you use in your web ACL but do not own, such as AWS Managed Rules rule groups. For more information about AWS WAF metrics, see AWS WAF metrics and AWS Shield Advanced metrics 1214 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide dimensions. For information about this Shield Advanced protection option, see Automating application layer DDoS mitigation with Shield Advanced . Metric reporting locations Shield Advanced reports metrics in the US East (N. Virginia) Region, us-east-1 for the following: • The global services Amazon CloudFront and Amazon Route 53. • Protection groups. For information about protection groups, see Grouping your AWS Shield Advanced protections. For other resource types, Shield Advanced reports metrics in the resource's Region.

Shield Advanced reports metrics once a minute during an event, and then once right after the event ends. While no events are underway, Shield Advanced reports metrics once a day, at a time assigned to the resource. This periodic report keeps the metrics active and available for use in custom CloudWatch alarms and dashboards. Alarm recommendations We recommend that you create alarms to notify you of circumstances that require attention. As a starting point, you could create an alarm for each protected resource that reports when the DDoSDetected detection metric is non zero. A non-zero value in this metric doesn't necessarily imply that a DDoS attack is underway, but we recommend looking closer at the resource status when the metric is in this state. For request floods, we recommend that you create alarms for composite checks that also consider factors such as application health and web request volume. You may choose to alarm on the other three metrics that report on the volume of traffic for various attack vector dimensions. By considering the capacity of your application and alarming when traffic is approaching your application limitations, you can create a set of rules that notify you as needed, without too much unwanted noise.

AWS Shield Advanced metrics 1219 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide AWS Firewall Manager notifications AWS Firewall Manager doesn't record metrics, so you can't create Amazon CloudWatch alarms specifically for Firewall Manager. However, you can configure Amazon SNS notifications to alert you to potential attacks. To create Amazon SNS notifications in Firewall Manager, see Step 4: Configuring Amazon SNS notifications and Amazon CloudWatch alarms. Logging API calls with AWS CloudTrail AWS WAF, AWS Shield Advanced, and AWS Firewall Manager are integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service. CloudTrail captures a subset of API calls for these services as events, including calls from the AWS WAF, Shield Advanced or Firewall Manager consoles and from code calls to the AWS WAF, Shield Advanced, or Firewall Manager APIs. If you create a trail, you can enable continuous delivery of CloudTrail events to an Amazon S3 bucket, including events for AWS WAF, Shield Advanced, or Firewall Manager. If you don't configure a trail, you can still view the most recent events in the CloudTrail console in Event history. Using the information collected by CloudTrail, you can determine the request that was made to these services, the IP address that the request was made from, who made the request, when it was made, and additional details. To learn more about CloudTrail, including how to configure and enable it, see the AWS CloudTrail User Guide. CloudTrail is enabled on your AWS account when you create the account. When supported event activity occurs in AWS WAF, Shield Advanced, or Firewall Manager, that activity is recorded in a CloudTrail event along with other AWS service events in Event history. You can view, search, and download recent events in your AWS account. For more information, see Viewing Events with CloudTrail Event History. For an ongoing record of events in your AWS account, including events for AWS WAF, Shield Advanced, or Firewall Manager, create a trail. A trail enables CloudTrail to deliver log files to an Amazon S3 bucket. By default, when you create a trail on the console, the trail applies to all Regions. The trail logs events from all Regions in the AWS partition and delivers the log files to the Amazon S3 bucket that you specify. Additionally, you can configure other AWS services to further analyze and act upon the event data collected in CloudTrail logs. For more information, see the following: • Overview for Creating a Trail AWS Firewall Manager notifications 1220 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • CloudTrail Supported Services and Integrations • Configuring Amazon SNS Notifications for CloudTrail • Receiving CloudTrail Log Files from Multiple Regions and Receiving CloudTrail Log Files from Multiple Accounts AWS WAF information in AWS CloudTrail All AWS WAF actions are logged by AWS CloudTrail and are documented in the AWS WAF API Reference. For example, calls to ListWebACL, UpdateWebACL, and DeleteWebACL generate entries in the CloudTrail log files. Every event or log entry contains information about who generated the request. The identity information helps you determine the following: • Whether the request was made with root user credentials • Whether the request was made with temporary security credentials for a role or federated user • Whether the request was made by another AWS service For more information, see CloudTrail userIdentity Element. Example: AWS WAF log file entries A trail is a configuration that enables delivery of events as log files to an Amazon S3 bucket that you specify. AWS CloudTrail log files contain one or more log entries. An event represents a single request from any source and includes information about the requested action, the date and time of the action, request parameters, and so on. CloudTrail log files are not an ordered stack trace of the public API calls, so they do not appear in any specific order. The following are examples of CloudTrail log entries for AWS WAF web ACL operations. Example: CloudTrail log entry for CreateWebACL { "eventVersion": "1.05", "userIdentity": { "type": "AssumedRole", "principalId": "principalId", "arn": "arn:aws:sts::112233445566:assumed-role/Admin", "accountId": "112233445566", AWS WAF information in AWS CloudTrail 1221 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide "accessKeyId": "accessKeyId", "sessionContext": { "sessionIssuer": { "type": |

This section will acquaint you with the components of requests, the content of responses, and how to authenticate requests. Topics • Using the AWS SDKs • Making HTTPS requests to AWS WAF or Shield Advanced • HTTP responses • Authenticating requests Using the AWS SDKs If you use a language that AWS provides an SDK for, use the SDK rather than trying to work your way through the APIs. The SDKs make authentication simpler, integrate easily with your development environment, and provide easy access to AWS WAF and Shield Advanced commands. For more information about the AWS SDKs, see Download tools in the topic Setting up your account to use the services. Making HTTPS requests to AWS WAF or Shield Advanced AWS WAF and Shield Advanced requests are HTTPS requests, as defined by RFC 2616. Like any HTTP request, a request to AWS WAF or Shield Advanced contains a request method, a URI, request headers, and a request body. The response contains an HTTP status code, response headers, and sometimes a response body. Request URI The request URI is always a single forward slash, /. HTTP headers AWS WAF and Shield Advanced require the following information in the header of an HTTP request: Using the AWS SDKs 1236 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Host (Required) The endpoint that specifies where your resources are created. For information about endpoints, see AWS service endpoints. For example, the value of the Host header for AWS WAF for a CloudFront distribution is waf.amazonaws.com:443. x-amz-date or Date (Required) The date used to create the signature that is contained in the Authorization header. Specify the date in ISO 8601 standard format, in UTC time, as shown in the following example: x-amz-date: 20151007T174952Z You must include either x-amz-date or Date. (Some HTTP client libraries don't let you set the Date header). When an x-amz-date header is present, AWS WAF ignores any Date header when authenticating the request. The time stamp must be within 15 minutes of the AWS system time when the request is received. If it isn't, the request fails with the RequestExpired error code to prevent someone else from replaying your requests. Authorization (Required) The information required for request authentication. For more information about constructing this header, see Authenticating requests. X-Amz-Target (Required) A concatenation of AWSWAF_ or AWSShield_, the API version without punctuation, a period (.), and the name of the operation, for example: AWSWAF_20150824.CreateWebACL Content-Type (Conditional) Specifies that the content type is JSON as well as the version of JSON, as shown in the following example: Content-Type: application/x-amz-json-1.1 Condition: Required for POST requests.

The following is an example header for an HTTP request to create a web ACL in AWS WAF: POST / HTTP/1.1 Host: waf.amazonaws.com:443 X-Amz-Date: 20151007T174952Z Authorization: AWS4-HMAC-SHA256 Credential=AccessKeyID/20151007/us-east-2/waf/aws4_request, SignedHeaders=host;x-amz-date;x-amz-target, Signature=145b1567ab3c50d929412f28f52c45dbf1e63ec5c66023d232a539a4afd11fd9 X-Amz-Target: AWSWAF_20150824.CreateWebACL Accept: */* Content-Type: application/x-amz-json-1.1; charset=UTF-8 Content-Length: 231 Connection: Keep-Alive HTTP request body Many AWS WAF and Shield Advanced API actions require you to include JSON-formatted data in the body of the request. The following example request uses a simple JSON statement to update an IPSet to include the IP address 192.0.2.44 (represented in CIDR notation as 192.0.2.44/32): POST / HTTP/1.1 Host: waf.amazonaws.com:443 X-Amz-Date: 20151007T174952Z Authorization: AWS4-HMAC-SHA256 Credential=AccessKeyID/20151007/us-east-2/waf/aws4_request, SignedHeaders=host;x-amz-date;x-amz-target, Signature=145b1567ab3c50d929412f28f52c45dbf1e63ec5c66023d232a539a4afd11fd9 X-Amz-Target: AWSWAF_20150824.UpdateIPSet Accept: */* HTTP request body 1238 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Content-Type: application/x-amz-json-1.1; charset=UTF-8 Content-Length: 283 Connection: Keep-Alive { "ChangeToken": "d4c4f53b-9c7e-47ce-9140-0ee5ffffffff", "IPSetId": "69d4d072-170c-463d-ab82-0643ffffffff", "Updates": [ { "Action": "INSERT", "IPSetDescriptor": { "Type": "IPV4", "Value": "192.0.2.44/32" } } ] } HTTP responses All AWS WAF and Shield Advanced API actions include JSON-formatted data in the response. Here are some important headers in the HTTP response and how you should handle them in your application, if applicable: HTTP/1.1 This header is followed by a status code. Status code 200 indicates a successful operation. Type: String x-amzn-RequestId A value created by AWS WAF or Shield Advanced that uniquely identifies your request, for example, K2QH8DNOU907N97FNA2GDLL8OBVV4KQNSO5AEMVJF66Q9ASUAAJG. If you have a problem with AWS WAF, AWS can use this value to troubleshoot the problem. Type: String Content-Length The length of the response body in bytes. HTTP responses 1239 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide Type: String Date The date and time that AWS WAF or Shield Advanced responded, for example, Wed, 07 Oct 2015 12:00:00 GMT. Type: String Error responses If a request results in an error, the HTTP response contains the following values: • A JSON error document as the response body • Content-Type • The applicable 3xx, 4xx, or 5xx HTTP status code The following is an example of a JSON error document: HTTP/1.1 400 Bad Request x-amzn-RequestId: b0e91dc8-3807-11e2-83c6-5912bf8ad066 x-amzn-ErrorType: ValidationException Content-Type: application/json Content-Length: 125 Date: Mon, 26 Nov 2012 20:27:25 GMT {"message":"1 validation error detected: Value null at 'TargetString' failed to satisfy constraint: Member must not be null"} Authenticating requests If you use a language that AWS provides an SDK for, we recommend that you use the SDK. All the AWS SDKs greatly simplify the process of signing requests and save you a significant amount of time when compared with using the AWS WAF or Shield Advanced API. In addition, the SDKs integrate easily with your development environment and provide easy access to related commands. AWS WAF and Shield Advanced require that you authenticate every request that you send by signing the request. To sign a request, you calculate a digital signature using a cryptographic hash function, which returns a hash value based on the input. The input includes the text of your request Error responses 1240 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide and your secret access key. The hash function returns a hash value that you include in the request as your signature. The signature is part of the Authorization header of your request. After receiving your request, AWS WAF or Shield Advanced recalculates the signature using the same hash function and input that you used to sign the request. If the resulting signature matches the signature in the request, AWS WAF or Shield Advanced processes the request. If not, the request is rejected. AWS WAF and Shield Advanced supports authentication using AWS Signature Version 4. The process for calculating a signature can be broken into three tasks: Task 1: Create a Canonical Request Create your HTTP request in canonical format as described in Task 1: Create a Canonical Request For Signature Version 4 in the Amazon Web Services General Reference. Task 2: Create a String to Sign Create a string that you will use as one of the input values to your cryptographic hash function. The string, called the string to sign, is a concatenation of the following values: • Name of the hash algorithm • Request date • Credential scope string • Canonicalized request from the previous |

The string, called the string to sign, is a concatenation of the following values: • Name of the hash algorithm • Request date • Credential scope string • Canonicalized request from the previous task The credential scope string itself is a concatenation of date, region, and service information. For the X-Amz-Credential parameter, specify the following: • The code for the endpoint to which you're sending the request, us-east-2 • waf for the service abbreviation For example: X-Amz-Credential=AKIAIOSFODNN7EXAMPLE/20130501/us-east-2/waf/ aws4_request Task 3: Create a Signature Create a signature for your request by using a cryptographic hash function that accepts two input strings: Authenticating requests 1241 AWS WAF, AWS Firewall Manager, and AWS Shield Advanced Developer Guide • Your string to sign, from Task 2. • A derived key. The derived key is calculated by starting with your secret access key and using the credential scope string to create a series of hash-based message authentication codes (HMACs).

September 17, 2024 • AWS WAF • AWS Shield AWS WAF (Web Application Firewall) and AWS Shield can help you protect your web applications against various types of cyberattacks, such as Distributed Denial of Service (DDoS) attacks and other web application vulnerabilities. • AWS WAF focuses on protecting your web applications from common web exploits. Use AWS WAF to create customizable web security rules to filter malicious traffic, protect against attacks such as SQL injection and cross-site scripting (XSS), and integrate with other AWS services. • AWS Shield is a managed DDoS protection service. Use AWS Shield to turn on always-on detection and automatic mitigations, and protect against common DDoS attacks at the network and transport layers. While AWS Shield defends against large-scale, network-level attacks, with AWS Shield Advanced, you can associate an AWS WAF web ACL with a resource to provide protection at the application layer. AWS WAF provides more granular protection against application-specific vulnerabilities. Use both services in tandem for a multi-layered defense strategy, safeguarding your applications from a broader range of potential threats across different network layers. Here's a high-level view of the key differences between these services. Introduction 1 AWS WAF or AWS Shield? AWS Decision guide Category AWS WAF AWS Shield Primary Purpose Protects against exploits on web applications (such as SQL Protects against DDoS attacks (such as SYN or UDP floods) injection or XSS) Layer of protection Application layer (L7) Deployment Must be explicitly set up Network, transport, and application layers (L3/L4/L7) AWS Shield Standard protection included for all customer accounts Customization Highly customizable with custom rules Turn on or disable AWS Shield Advanced, with options to Managed Rules Pricing model Includes AWS Managed Rules and third-party rules Pay-as-you-go pricing based on number of rules and requests Attack Response Team Not applicable turn on automatic mitigatio n of application layer DDoS protections Not applicable AWS Shield Standard included; AWS Shield Advanced incurs additional cost Available with AWS Shield Advanced (24/7 DDoS Response Team) Real-time monitoring Yes Yes Traffic Inspection Request-level Packet-level Introduction 2 AWS WAF or AWS Shield? AWS Decision guide Differences between AWS WAF and AWS Shield Explore eight key areas of difference between AWS Shield and AWS WAF, covering layer of protection, deployment, customization, managed rules, pricing model, attack response team, real- time monitoring, and traffic inspection. Layer of protection AWS WAF • Operates at the application layer (Layer 7). It protects web applications by filtering and monitoring HTTP/S traffic. AWS WAF defends against common web exploits such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). You can create custom rules to block malicious requests based on various criteria like IP addresses, query strings, and headers. AWS Shield • Operates primarily at the network (Layer 3) and transport (Layer 4) layers. It is designed to mitigate Distributed Denial of Service (DDoS) attacks that aim to overwhelm network resources, such as SYN/ACK floods, UDP reflection attacks, and volumetric attacks. AWS Shield ensures that network traffic reaching your AWS resources remains available even under attack. AWS Shield's protection works by analyzing network traffic patterns and automatically mitigating identified threats at the AWS network edge. Deployment AWS WAF • Requires explicit setup and configuration. It can be deployed on multiple AWS services, including Amazon CloudFront, Application Load Balancer (ALB), Amazon API Gateway, and AWS AppSync. You must create and associate web ACLs (Access Control Lists) with your resources, defining rules to allow, block, or monitor specific web requests. AWS WAF offers customizable deployment options, allowing you to tailor security policies to your specific application needs. AWS Shield Differences 3 AWS WAF or AWS Shield? AWS Decision |
waf-or-shield-002 | waf-or-shield.pdf | 2 | AWS Shield's protection works by analyzing network traffic patterns and automatically mitigating identified threats at the AWS network edge. Deployment AWS WAF • Requires explicit setup and configuration. It can be deployed on multiple AWS services, including Amazon CloudFront, Application Load Balancer (ALB), Amazon API Gateway, and AWS AppSync. You must create and associate web ACLs (Access Control Lists) with your resources, defining rules to allow, block, or monitor specific web requests. AWS WAF offers customizable deployment options, allowing you to tailor security policies to your specific application needs. AWS Shield Differences 3 AWS WAF or AWS Shield? AWS Decision guide • Automatically integrated with AWS services and is always on, requiring no additional setup for basic protection. AWS Shield Standard is automatically included with all AWS accounts, protecting resources like Amazon EC2, Elastic Load Balancing (ELB), Amazon CloudFront, and Route 53. For enhanced protection with AWS Shield Advanced, you must explicitly turn it on for specific resources. Deployment is seamless, and no additional configuration is necessary once AWS Shield is turned on. Customization AWS WAF • Provides extensive customization capabilities. You can create custom web ACLs (Access Control Lists) with rules that define specific conditions for allowing, blocking, or counting web requests based on IP addresses, HTTP headers, query string parameters, and more. AWS WAF supports managed rule groups from AWS or third parties, which can be customized further to suit your specific application needs. You can also set up rate-based rules to limit the number of requests from a single IP address and integrate AWS WAF with AWS Lambda for advanced request inspection and response. AWS Shield • Offers limited customization options. With AWS Shield Standard, protection is automatic and non-configurable. AWS Shield Advanced allows for some customization, such as enabling advanced metrics and alerts, setting up Health Checks, and accessing the AWS DDoS Response Team (DRT) for tailored mitigation support. However, its focus remains on automated DDoS protection rather than user-defined settings. You can associate an AWS WAF web ACL with resources to turn on application layer protection. Managed rules AWS WAF • Offers a range of managed rules that can be applied to web applications to protect against common web threats. These managed rules are pre-configured by AWS or third-party security vendors and cover various security scenarios such as SQL injection, cross-site scripting (XSS), and known bad IP addresses. You can subscribe to and apply these managed rule groups to your web ACLs, providing out-of-the-box protection that is regularly updated to address new Differences 4 AWS WAF or AWS Shield? AWS Decision guide vulnerabilities and threats. Managed rules can be customized and combined with custom rules to tailor security policies to specific application needs. AWS WAF also provides managed intelligent threat mitigation features. These are advanced, specialized protections that you can implement to protect against threats such as malicious bots and account takeover attempts. AWS Shield • Primarily focused on DDoS protection, and doesn't offer traditional managed rules. AWS Shield Standard automatically applies a set of predefined protections against common network and transport layer DDoS attacks. AWS Shield Advanced enhances these protections but doesn't provide customizable managed rules. Instead, it offers more advanced mitigation techniques and access to the DDoS Response Team for tailored assistance. Pricing model AWS WAF • Uses a pay-as-you-go pricing model. You are charged based on the number of web ACLs you create, the number of rules you deploy within each ACL, and the number of web requests processed by the rules. This model allows for scalable costs based on actual usage, meaning you only pay for the resources you need. Additional charges apply for managed rule groups provided by AWS or third-party vendors. AWS WAF also provides managed rules for Bot control and fraud control with a similar per request pricing model. AWS WAF also offers a captcha/challenge feature which is charged by the number of captcha attempts and challenge responses served. AWS Shield • Has a tiered pricing model. AWS Shield Standard is included at no additional cost with all AWS accounts, providing basic DDoS protection. AWS Shield Advanced incurs a fee based on a monthly subscription and additional charges for data transfer and mitigation beyond a certain threshold. This subscription includes 24/7 access to the AWS DDoS Response Team (DRT), advanced attack diagnostics, and cost protection during attacks. Differences 5 AWS WAF or AWS Shield? Attack response team AWS WAF AWS Decision guide • Does not include a dedicated attack response team as part of its service. Instead, it provides tools and features that allow you to create, manage, and adjust security rules themselves. You can monitor traffic and make real-time changes to your web ACLs based on the threat landscape, but you don't have direct access to a specialized support team for attack mitigation.

Differences 5 AWS WAF or AWS Shield? Attack response team AWS WAF AWS Decision guide • Does not include a dedicated attack response team as part of its service. Instead, it provides tools and features that allow you to create, manage, and adjust security rules themselves. You can monitor traffic and make real-time changes to your web ACLs based on the threat landscape, but you don't have direct access to a specialized support team for attack mitigation. AWS Shield • Offers access to the AWS DDoS Response Team (DRT) as part of its AWS Shield Advanced service. The DRT is a 24/7 team of experts that assists with real-time attack mitigation and response. When under a DDoS attack, you can contact the DRT for customized advice and support to manage and mitigate the threat effectively. This includes guidance on best practices, incident analysis, and coordinated responses to minimize the impact on your AWS resources. Real-time monitoring AWS WAF • Offers real-time monitoring by integrating with AWS CloudWatch, allowing you to track metrics such as blocked or allowed requests, request rates, and the effectiveness of specific rules. AWS WAF provides near real-time visibility into web traffic and security events through the AWS Management Console or APIs. You can set up custom CloudWatch alarms based on your AWS WAF metrics to respond quickly to potential threats or unusual traffic patterns. AWS Shield • Provides real-time monitoring primarily through AWS Shield Advanced. It integrates with AWS CloudWatch to deliver near real-time metrics and alerts related to DDoS attacks. You can monitor attack diagnostics, traffic patterns, and the effectiveness of mitigations. AWS Shield Advanced also offers detailed reports and visibility into attack vectors and scales automatically in response to threats, providing insights through the AWS Management Console. Differences 6 AWS WAF or AWS Shield? AWS Decision guide Both services provide dashboards for visualizing attack patterns and traffic trends. AWS Shield's monitoring focuses on network-level anomalies and volumetric attacks, while AWS WAF provides deeper insights into application-layer requests and rule effectiveness. Traffic inspection AWS WAF • Inspects traffic at the application layer (Layer 7), analyzing the contents of HTTP/S requests. It evaluates web traffic against user-defined rules, checking for specific attack patterns such as SQL injection, cross-site scripting (XSS), or other malicious payloads within the request body, headers, or URL parameters. AWS Shield • Focuses on protecting against DDoS attacks, primarily inspecting traffic at the network (Layer 3) and transport (Layer 4) layers. It does not inspect the contents of application layer traffic (HTTP/S), but rather looks for patterns typical of DDoS attacks, such as unusually high traffic volumes or protocol misuse. AWS Shield automatically mitigates these threats without user- defined rules or content-based inspection, ensuring the availability of AWS services under attack. Use AWS WAF • What is AWS WAF?

DCV Web Client SDK? Note Amazon DCV was previously known as NICE DCV. Amazon DCV is a high-performance remote display protocol. It lets you securely deliver remote desktops and application streaming from any cloud or data center to any device, over varying network conditions. By using Amazon DCV with Amazon EC2, you can run graphics-intensive applications remotely on Amazon EC2 instances. You can then stream the results to more modest client machines, which eliminates the need for expensive dedicated workstations. The Amazon DCV Web Client SDK is a JavaScript library that you can use to develop your own Amazon DCV web browser client applications. Your end users can use these applications to connect to and interact with a running Amazon DCV session. Using the Amazon DCV Web Client SDK as a building block, you can build customized web applications that provide users with instant access to their desktop or applications from anywhere, with a responsive and fluid performance that is almost indistinguishable from a natively installed application. This guide explains how to use the Amazon DCV Web Client SDK to build your custom web browser client applications to interact with Amazon DCV sessions within your workflows. Topics • Prerequisites • Supported features • Browser support • Versioning convention Prerequisites Before you start working with the Amazon DCV Web Client SDK, ensure that you're familiar with Amazon DCV and Amazon DCV sessions.

The versioning convention generally adheres to the semantic versioning model. A change in the major version, such as from 1.x.x to 2.x.x, indicates that breaking changes that might require code changes and a planned deployment have been introduced. A change in the minor version, such as from 1.1.x to 1.2.x, is backwards compatible, but might include deprecated elements. Versioning convention 3 Amazon DCV Web Client SDK Developer Guide Getting started with the Amazon DCV Web Client SDK The Amazon DCV Web Client SDK comprises of a main dcv.js file and some auxiliary components. All the files are distributed inside a compressed archive that can be downloaded from the Amazon DCV website . To get started with the Amazon DCV Web Client SDK 1. The Amazon DCV Web Client SDK archive is digitally signed with a secure GPG signature. To verify the archive's signature, you must import the NICE GPG key. To do so, open a terminal window and import the NICE GPG key. $ wget https://d1uj6qtbmh3dt5.cloudfront.net/NICE-GPG-KEY $ gpg --import NICE-GPG-KEY 2. Download the Amazon DCV Web Client SDK archive and the Amazon DCV Web Client SDK archive signature from the Amazon DCV website . 3. Verify the signature of the Amazon DCV Web Client SDK archive using the signature. $ gpg --verify signature_filename.zip.sign archive_filename.zip For example: $ gpg --verify nice-dcv-web-client-sdk-1.8.7-858.zip.sign nice-dcv-web-client- sdk-1.8.7-858.zip 4. If the signature verifies successfully, extract the contents of the Amazon DCV Web Client SDK archive and place the extracted directory on your web server. For example: $ unzip archive_filename.zip -d / path_to 4 Amazon DCV / server_directory / Important Web Client SDK Developer Guide • You must retain the folder structure when deploying the Amazon DCV Web Client SDK on your web server. • When using Amazon DCV Web UI SDK, please beware that the DCVViewer React component expects the EULA.txt and third-party-licenses.txt files from this package to be present in the URL path for the embedded web server. The third-party- licenses.txt file should be modified to also include the content of the corresponding file from Amazon DCV Web Client SDK package and possibly any other license information from the libraries used by the consuming user application. Connect to a Amazon DCV server and get the first frame The following tutorial shows you how to prepare your HTML page for your custom web client, how to authenticate and connect to a Amazon DCV server, and how to receive the first frame of streamed content from the Amazon DCV session. Topics • Step 1: Prepare your HTML page • Step 2: Authenticate, connect, and get the first frame • Bonus: Automatically create an HTML login form Step 1: Prepare your HTML page In your web page, you must load the needed JavaScript modules and you must add a <div> HTML element with a valid id where you want the Amazon DCV Web Client SDK to draw the content stream from the remote Amazon DCV server. For example: <!DOCTYPE html> Connect to a Amazon DCV server and get the first frame 5 Amazon DCV Web Client SDK Developer Guide <html lang="en" style="height: 100%;"> <head> <title>DCV first connection</title> </head> <body style="height: 100%;"> <div id="root" style="height: 100%;"></div> <div id="dcv-display"></div> <script type="module" src="index.js"></script> </body> </html> Step 2: Authenticate, connect, and get the first frame This section shows how to complete the user authentication process, how to connect the Amazon DCV server, and how to receive the first frame of content from the Amazon DCV server. First, from the index.js file import the Amazon DCV Web Client SDK. |
websdkguide-003 | websdkguide.pdf | 3 | DCV server. For example: <!DOCTYPE html> Connect to a Amazon DCV server and get the first frame 5 Amazon DCV Web Client SDK Developer Guide <html lang="en" style="height: 100%;"> <head> <title>DCV first connection</title> </head> <body style="height: 100%;"> <div id="root" style="height: 100%;"></div> <div id="dcv-display"></div> <script type="module" src="index.js"></script> </body> </html> Step 2: Authenticate, connect, and get the first frame This section shows how to complete the user authentication process, how to connect the Amazon DCV server, and how to receive the first frame of content from the Amazon DCV server. First, from the index.js file import the Amazon DCV Web Client SDK. It can be imported either as a Universal Module Definition (UMD) module, like so: import "./dcvjs/dcv.js" Otherwise, starting from version 1.1.0, it can also be imported as a ECMAScript Module (ESM) from the corresponding package, like so: import dcv from "./dcvjs/dcv.js" Define the variables to use to store the Authentication object, Connection object, and the Amazon DCV server URL. let auth, connection, serverUrl; On script load, log the Amazon DCV Web Client SDK version, and on page load, call the main function. console.log("Using Amazon DCV Web Client SDK version " + dcv.version.versionStr); document.addEventListener('DOMContentLoaded', main); The main function sets the log level and starts the authentication process. Step 2: Authenticate, connect, and get the first frame 6 Amazon DCV Web Client SDK Developer Guide function main () { console.log("Setting log level to INFO"); dcv.setLogLevel(dcv.LogLevel.INFO); serverUrl = "https://your-dcv-server-url:port/"; console.log("Starting authentication with", serverUrl); auth = dcv.authenticate( serverUrl, { promptCredentials: onPromptCredentials, error: onError, success: onSuccess } ); } The promptCredentials , error , and success functions are mandatory callback functions that must be defined in the authentication process. If the Amazon DCV server prompts for credentials, the promptCredentials callback function receives the requested credential challenge from the Amazon DCV server. If the Amazon DCV server is configured to use system authentication, then the sign-in credentials must be provided. The following code samples assume that the username is my_dcv_user and that the password is my_password. If authentication fails, the error callback function receives an error object from the Amazon DCV server. If the authentication succeeds, the success callback function receives an array of couples that includes the session id ( sessionId ) and authorization tokens ( authToken ) for each session that the my_dcv_user user is allowed to connect to on the Amazon DCV server. The following code sample calls the connect function and connects to the first session returned in the array. Note In the following code example, replace MY_DCV_USER with your own username and MY_PASSWORD with your own password. Step 2: Authenticate, connect, and get the first frame 7 Amazon DCV Web Client SDK Developer Guide function onPromptCredentials(auth, challenge) { // Let's check if in challege we have a username and password request if (challengeHasField(challenge, "username") && challengeHasField(challenge, "password")) { auth.sendCredentials({username: MY_DCV_USER, password: MY_PASSWORD}) } else { // Challenge is requesting something else... } } function challengeHasField(challenge, field) { return challenge.requiredCredentials.some(credential => credential.name === field); } function onError(auth, error) { console.log("Error during the authentication: " + error.message); } // We connect to the first session returned function onSuccess(auth, result) { let {sessionId, authToken} = {...result[0]}; connect(sessionId, authToken); } Connect to the Amazon DCV server. The firstFrame callback method is called when the first frame is received from the Amazon DCV server. function connect (sessionId, authToken) { console.log(sessionId, authToken); dcv.connect({ url: serverUrl, sessionId: sessionId, authToken: authToken, divId: "dcv-display", callbacks: { firstFrame: () => console.log("First frame received") } }).then(function (conn) { console.log("Connection established!"); connection= conn; }).catch(function (error) { Step 2: Authenticate, connect, and get the first frame 8 Amazon DCV Web Client SDK Developer Guide console.log("Connection failed with error " + error.message); }); } Bonus: Automatically create an HTML login form The challenge object is returned when the promptCredentials callback function is called. It includes a property named requiredCredentials that is an array of objects - one object per credential that is requested by the Amazon DCV server. Each object includes the name and the type of the requested credential. You can use the challenge and requiredCredentials objects to automatically create an HTML login form. The following code sample shows you how to do this. let form, fieldSet; function submitCredentials (e) { var credentials = {}; fieldSet.childNodes.forEach(input => credentials[input.id] = input.value); auth.sendCredentials(credentials); e.preventDefault(); } function createLoginForm () { var submitButton = document.createElement("button"); submitButton.type = "submit"; submitButton.textContent = "Login"; form = document.createElement("form"); fieldSet = document.createElement("fieldset"); form.onsubmit = submitCredentials; form.appendChild(fieldSet); form.appendChild(submitButton); document.body.appendChild(form); } function addInput (name) { var type = name === "password" ?

The features that are available in a Amazon DCV session are managed by the permissions that have been specified for the session. This means that even if a feature is supported by the Amazon DCV Web Client SDK, access to that feature might be prevented based on the permissions defined by the session administrator. For more information, see Configuring Amazon DCV Authorization in the Amazon DCV Administrator Guide . Understanding the featuresUpdate callback function When the availability of a feature in a Amazon DCV session changes, the Amazon DCV Web Client SDK notifies you using the featuresUpdate callback function that you specify at the time of establishing the connection. For example: featuresUpdate: function (connection, list) { ... }, The callback function notifies you only of the features for which the availability has changed. The list parameter is an array of strings, and it includes only the names of the updated features. For example, if the availability of the audio input feature changes for the session, the parameter Work with Amazon DCV features 10 Amazon DCV Web Client SDK Developer Guide includes only ["audio-in"] . If at a later point, the availability of the clipboard copy and paste features change for the session, the parameter includes only ["clipboard-copy", "clipboard-paste"] . Handling feature updates The featuresUpdate callback function only notifies you that the availability of one or more features has changed. To know which features were updated, you must query the feature using the connection.queryFeature method. This can be done at any time after the notification of change has been received. This method returns a Promise that resolves to the requested feature's updated status. The status value is always associated and it has a Boolean ( true | false ) property called enabled . Some features might have additional properties in the status value. If the feature's availability has not been updated, it's rejected. The following example code shows how to do this. // Connection callback called function featuresUpdate (_, list) { if (list.length > 0) { list.forEach((feat) => { connection.queryFeature(feat).then(status => console.log(feat, "is", status.enabled))); }); } } Use Amazon DCV Web UI SDK The following tutorial shows you how to authenticate against the Amazon DCV server, connect to it and render the DCVViewer React component from the Amazon DCV Web UI SDK. Topics • Prerequisites • Step 1: Prepare your HTML page • Step 2: Authenticate, connect and render the DCVViewer React component. • Updating from AWS-UI to Cloudscape Design System Handling feature updates 11 Amazon DCV Prerequisites Web Client SDK Developer Guide You need to install React , ReactDOM , Cloudscape Design Components React , Cloudscape Design Global Styles and Cloudscape Design Design Tokens . $ npm i react react-dom @cloudscape-design/components @cloudscape-design/global-styles @cloudscape-design/design-tokens You would also need to download Amazon DCV Web Client SDK . See Getting started with the Amazon DCV Web Client SDK to read the step-by-step guide on how to do that. You must create an alias for importing the dcv module, since it is an external dependency for Amazon DCV Web UI SDK. For instance, if you are using webpack to bundle your web app, you can use the resolve.alias option like so: const path = require('path'); module.exports = { //... resolve: { alias: { dcv: path.resolve('path', 'to', 'dcv.js'), }, }, }; If you are using rollup for bundling, you can install @rollup/plugin-alias, and use it like so: import alias from '@rollup/plugin-alias'; const path = require('path'); module.exports = { //... plugins: [ alias({ entries: [ { find: 'dcv', replacement: path.resolve('path', 'to', 'dcv.js') }, ] }) ] }; Prerequisites 12 Amazon DCV Web Client SDK Developer Guide Step 1: Prepare your HTML page In your web page, you must load the required JavaScript modules and you should have a <div> HTML element with a valid id where the entry component of your app will be rendered. For example: <!DOCTYPE html> <html lang="en" style="height: 100%;"> <head> <title>DCV first connection</title> </head> <body style="height: 100%;"> <div id="root" style="height: 100%;"></div> <script type="module" src="index.js"></script> </body> </html> Step 2: Authenticate, connect and render the DCVViewer React component.

This section shows how to complete the user authentication process, how to connect the Amazon DCV server, and how to render the DCVViewer React component. First, from the index.js file, import React , ReactDOM and your top level App component. import React from "react"; import ReactDOM from 'react-dom'; import App from './App'; Render the top level container node of your app. ReactDOM.render( <React.StrictMode> <App /> </React.StrictMode>, document.getElementById("root") ); Step 1: Prepare your HTML page 13 Amazon DCV Web Client SDK Developer Guide In the App.js file, import the Amazon DCV Web Client SDK as a ESM module, the DCVViewer React component from the Amazon DCV Web UI SDK, React and the Cloudscape Design Global Styles package. import React from "react"; import dcv from "dcv"; import "@cloudscape-design/global-styles/index.css"; import {DCVViewer} from "./dcv-ui/dcv-ui.js"; Following is an example showing how to authenticate against the Amazon DCV Server and render the DCVViewer React component from Amazon DCV Web UI SDK, provided the authentication was successful. const LOG_LEVEL = dcv.LogLevel.INFO; const SERVER_URL = "https://your-dcv-server-url:port/"; const BASE_URL = "/static/js/dcvjs"; let auth; function App() { const [authenticated, setAuthenticated] = React.useState(false); const [sessionId, setSessionId] = React.useState(''); const [authToken, setAuthToken] = React.useState(''); const [credentials, setCredentials] = React.useState({}); const onSuccess = (_, result) => { var { sessionId, authToken } = { ...result[0] }; console.log("Authentication successful."); setSessionId(sessionId); setAuthToken(authToken); setAuthenticated(true); setCredentials({}); } const onPromptCredentials = (_, credentialsChallenge) => { let requestedCredentials = {}; credentialsChallenge.requiredCredentials.forEach(challenge => requestedCredentials[challenge.name] = ""); setCredentials(requestedCredentials); Step 2: Authenticate, connect and render the DCVViewer React component. 14 Web Client SDK Developer Guide Amazon DCV } const authenticate = () => { dcv.setLogLevel(LOG_LEVEL); auth = dcv.authenticate( SERVER_URL, { promptCredentials: onPromptCredentials, error: onError, success: onSuccess } ); } const updateCredentials = (e) => { const { name, value } = e.target; setCredentials({ ...credentials, [name]: value }); } const submitCredentials = (e) => { auth.sendCredentials(credentials); e.preventDefault(); } React.useEffect(() => { if (!authenticated) { authenticate(); } }, [authenticated]); const handleDisconnect = (reason) => { console.log("Disconnected: " + reason.message + " (code: " + reason.code + ")"); auth.retry(); setAuthenticated(false); } return ( authenticated ? <DCVViewer dcv={{ Step 2: Authenticate, connect and render the DCVViewer React component. 15 Amazon DCV Web Client SDK Developer Guide sessionId: sessionId, authToken: authToken, serverUrl: SERVER_URL, baseUrl: BASE_URL, onDisconnect: handleDisconnect, logLevel: LOG_LEVEL }} uiConfig={{ toolbar: { visible: true, fullscreenButton: true, multimonitorButton: true, }, }} /> : <div style={{ height: window.innerHeight, backgroundColor: "#373737", display: 'flex', alignItems: 'center', justifyContent: 'center', }} > <form> <fieldset> {Object.keys(credentials).map((cred) => ( <input key={cred} name={cred} placeholder={cred} type={cred === "password" ? "password" : "text"} onChange={updateCredentials} value={credentials[cred]} /> ))} </fieldset> <button type="submit" onClick={submitCredentials} > Login </button> Step 2: Authenticate, connect and render the DCVViewer React component. 16 Amazon DCV </form> </div> ); } Web Client SDK Developer Guide const onError = (_, error) => { console.log("Error during the authentication: " + error.message); } export default App; The promptCredentials , error , and success functions are mandatory callback functions that must be defined in the authentication process. If the Amazon DCV server prompts for credentials, the promptCredentials callback function receives the requested credential challenge from the Amazon DCV server. If the Amazon DCV server is configured to use system authentication, then the credentials must be provided in the form of a user name and a password. If authentication fails, the error callback function receives an error object from the Amazon DCV server. If the authentication succeeds, the success callback function receives an array of couples that includes the session id ( sessionId ) and authorization tokens ( authToken ) for each session that the user is allowed to connect to on the Amazon DCV server. The code sample above updates the React state to render the DCVViewer component on successful authentication.
