different users should be granted different access privileges with regard to different data pieces. The access authorization must be controlled only by the owner in untrusted cloud environments. Access control can also be referred to as availability. While unauthorized access should be strictly prohibited, access for administrative or even consumer uses should be allowed but monitored as well. Availability and Access control ensure that the proper amount of permissions is granted to the correct persons. Integrity Data integrity demands maintaining and assuring the accuracy and completeness of data. A data owner always expects that her or his data in a cloud can be stored correctly and trustworthy. It means that the data should not be illegally tampered with, improperly modified, deliberately deleted, or maliciously fabricated. If any undesirable operations corrupt or delete the data, the owner should be able to detect the corruption or loss. Further, when a portion of the outsourced data is corrupted or lost, it can still be retrieved by the data users. Effective integrity security controls go beyond protection from malicious actors and protect data from unintentional alterations as well. An example of security control that covers integrity is automated backups of information. Risks and vulnerabilities of Cloud Computing While cloud computing is on the cutting edge of information technology there are risks and vulnerabilities to consider before investing fully in it. Security controls and services do exist for the cloud but as with any security system they are not guaranteed to succeed. Furthermore, some risks extend beyond asset security and may involve issues in productivity and even privacy as well. Privacy Concerns Cloud computing is still an emerging technology and thus is developing in relatively new technological structures. As a result, all cloud services must undertake Privacy Impact Assessments or PIAs before releasing their platform. Consumers as well that intend to use clouds to store their customer's data must also be aware of the vulnerabilities of having non-physical storage for private information. Unauthorized Access to Management interface Due to the autonomous nature of the cloud, consumers are often given management interfaces to monitor their databases. By having controls in such a congregated location and by having the interface be easily accessible for convenience for users, there is a possibility that a single actor could gain access to the cloud's management interface; giving them a great deal of control and power over the database.
