Description This application claims the benefit, pursuant to 35 U.S.C. �119 (e), of applicant's provisional U.S. patent application Ser. No. 60/381,829, filed May 20, 2002, entitled �SYSTEMS AND METHODS FOR NETWORK SECURITY�, which application is hereby incorporated by this reference in its entirety for all purposes. This application is related to the following U.S. Patent Applications filed Jun. 3, 2002, each of which is hereby incorporated by this reference in its entirety for all purposes:
The present invention is directed to systems and methods for enhancing security associated with electronic communications. More specifically, without limitation, the present invention relates to computer-based systems and methods for assessing security risks and identifying and responding to threats in wireless network environments. The Internet is a global network of connected computer networks. Over the last several years, the Internet has grown in significant measure. A large number of computers on the Internet provide information in various forms. Anyone with a computer connected to the Internet can potentially tap into this vast pool of information. The information available via the Internet encompasses information available via a variety of types of application layer information servers such as SMTP (simple mail transfer protocol), POP3 (Post Office Protocol), GOPHER (RFC 1436), WAIS, HTTP (Hypertext Transfer Protocol, RFC 2616) and FTP (file transfer protocol, RFC 1123). One of the most wide spread method of providing information over the Internet is via the World Wide Web (the Web). The Web consists of a subset of the computers connected to the Internet; the computers in this subset run Hypertext Transfer Protocol (HTTP) servers (Web servers). Several extensions and modifications to HTTP have been proposed including, for example, an extension framework (RFC 2774) and authentication (RFC 2617). Information on the Internet can be accessed through the use of a Uniform Resource Identifier (URI, RFC 2396). A URI uniquely specifies the location of a particular piece of information on the Internet. A URI will typically be composed of several components. The first component typically designates the protocol by which the address piece of information is accessed (e.g., HTTP, GOPHER, etc.). This first component is separated from the remainder of the URI by a colon (�:�). The remainder of the URI will depend upon the protocol component. Typically, the remainder designates a computer on the Internet by name, or by IP number, as well as a more specific designation of the location of the resource on the designated computer. For instance, a typical URI for an HTTP resource might be:
where http is the protocol, www.server.com is the designated computer and /dir1/dir2/resouce.htm designates the location of the resource on the designated computer. The term URI includes Uniform Resource Names (URN's) including URN's as defined according to RFC 2141. Web servers host information in the form of Web pages; collectively the server and the information hosted are referred to as a Web site. A significant number of Web pages are encoded using the Hypertext Markup Language (HTML) although other encodings using extensible Markup Language (XML) or XHTML. The published specifications for these languages are incorporated by reference herein; such specifications are available from the World Wide Web Consortium and its Web site (http://www.w3c.org). Web pages in these formatting languages may include links to other Web pages on the same Web site or another. As will be known to those skilled in the art, Web pages may be generated dynamically by a server by integrating a variety of elements into a formatted page prior to transmission to a Web client. Web servers, and information servers of other types, await requests for the information from Internet clients. Client software has evolved that allows users of computers connected to the Internet to access this information. Advanced clients such as Netscape's Navigator and Microsoft's Internet Explorer allow users to access software provided via a variety of information servers in a unified client environment. Typically, such client software is referred to as browser software. Electronic mail (e-mail) is another wide spread application using the Internet. A variety of protocols are often used for e-mail transmission, delivery and processing including SMTP and POP3 as discussed above. These protocols refer, respectively, to standards for communicating e-mail messages between servers and for server-client communication related to e-mail messages. These protocols are defined respectively in particular RFC's (Request for Comments) promulgated by the IETF (Internet Engineering Task Force). The SMTP protocol is defined in RFC 821, and the POP3 protocol is defined in RFC 1939. Since the inception of these standards, various needs have evolved in the field of e-mail leading to the development of further standards including enhancements or additional protocols. For instance, various enhancements have evolved to the SMTP standards leading to the evolution of extended SMTP. Examples of extensions may be seen in (1) RFC 1869 that defines a framework for extending the SMTP service by defining a means whereby a server SMTP can inform a client SMTP as to the service extensions it supports and in (2) RFC 1891 that defines an extension to the SMTP service, which allows an SMTP client to specify (a) that delivery status notifications (DSNs) should be generated under certain conditions, (b) whether such notifications should return the contents of the message, and (c) additional information, to be returned with a DSN, that allows the sender to identify both the recipient(s) for which the DSN was issued, and the transaction in which the original message was sent. In addition, the IMAP protocol has evolved as an alternative to POP3 that supports more advanced interactions between e-mail servers and clients. This protocol is described in RFC 2060. The various standards discussed herein by reference to particular RFC's are hereby incorporated by reference herein for all purposes. These RFC's are available to the public through the Internet Engineering Task Force (IETF) and can be retrieved from its Web site (http://www.ietf.org/rfc.html). The specified protocols are not intended to be limited to the specific RFC's quoted herein above but are intended to include extensions and revisions thereto. Such extensions and/or revisions may or may not be encompassed by current and/or future RFC's. A host of e-mail server and client products have been developed in order to foster e-mail communication over the Internet. E-mail server software includes such products as sendmail-based servers, Microsoft Exchange, Lotus Notes Server, and Novell GroupWise; sendmail-based servers refer to a number of variations of servers originally based upon the sendmail program developed for the UNIX operating systems. A large number of e-mail clients have also been developed that allow a user to retrieve and view e-mail messages from a server; example products include Microsoft Outlook, Microsoft Outlook Express, Netscape Messenger, and Eudora. In addition, some e-mail servers, or e-mail servers in conjunction with a Web server, allow a Web browser to act as an e-mail client using the HTTP standard. As the Internet has become more widely used, it has also created new risks for corporations. Breaches of computer security by hackers and intruders and the potential for compromising sensitive corporate information are a very real and serious threat. Wireless Local Area Networks (WLANs) offer a quick and effective extension of a wired network or standard local area network (LAN). Over the last few years, most deployments of WLANs have conformed to the Institute of Electrical and Electronics Engineers (IEEE) 802.11b standard that operates over the unregulated 2.4 GHz frequency spectrum. The 802.11b standard offers connectivity of up to 11 Mbps�fast enough to handle large e-mail attachments and run bandwidth-intensive applications like video conferencing. While the 802.11b standard now dominates the WLAN market, other variations of the 802.11 standard, such as 802.11a, 802.11g, and 802.1X, are being developed to handle increased speeds. WLAN vendors have committed to supporting a variety of standards. The various 802.11 standards developed by the IEEE are available for download via URL:
As businesses connected their LANs to the Internet 160, they installed firewalls 145 to protect their local networks and act as security gates to fend off unauthorized traffic coming from the Internet's information highway such as potential hacker 135. The mobility of air-bound, wireless networks creates security concerns where threats can come from any direction and are not limited to the wired infrastructure. Established security practices of guarding a few wired entry points to the network are no longer effective. A firewall 145 may effectively deter an attack from a wired hacker 135 via the Internet 160; however, wireless hackers 195A, 195B typically enter the LAN 190 through access points 180A, 180B that are already behind the firewall 145. Companies must constantly monitor their airwaves to survey wireless activity and guard against intruders. Because wireless communication is broadcast over radio waves, eavesdroppers 195A, 195B who merely listen to the airwaves can easily pick up unencrypted messages. Additionally, messages encrypted with the Wired Equivalent Privacy (WEP) security protocol can be decrypted with a little time and easily available hacking tools. These passive intruders put businesses at risk of exposing sensitive information to corporate espionage. The theft of an authorized user's identity poses one the greatest threats. Service Set Identifiers (SSIDs) that act as crude passwords and Media Access Control (MAC) addresses that act as personal identification numbers are often used to verify that clients are authorized to connect with an access point. However, existing encryption standards are not foolproof and allow knowledgeable intruders to pick up approved SSIDs and MAC addresses to connect to a WLAN as an authorized user with the ability to steal bandwidth, corrupt or download files, and wreak havoc on the entire network. Outsiders who cannot gain access to a WLAN can none-the-less pose security threats by jamming or flooding the airwaves with static noise that causes WLAN signals to collide and produce CRC errors. These Denial-of-Service (DoS) attacks effectively shut down the wireless network in a similar way that DoS attacks affect wired networks. Careless and deceitful actions by both loyal and disgruntled employees also present security risks and performance issues to wireless networks with unauthorized access points, improper security measures, and network abuses. Because a simple WLAN can be easily installed by attaching a $150 access point to a wired network and a $100 WLAN card to a laptop, employees are deploying unauthorized WLANs or peer-to-peer wireless connections 175 when IT departments are slow to adopt the new technology. Incorrectly configured access points are an avoidable but significant hole in WLAN security. Many access points are initially configured to broadcast unencrypted SSIDs of authorized users. While SSIDs are intended to be passwords to verify authorized users, intruders can easily steal an unencrypted SSID to assume the identity of an authorized user. Authorized users can also threaten the integrity of the network with abuses that drain connection speeds, consume bandwidth, and hinder a WLAN's overall performance. A few users who clog the network by trading large files such as MP3 audio or MPEG video files can affect the productivity of everyone on the wireless network. The systems and methods according to the present invention provide solutions to these and other security and/or management issues associated with WLANs and/or encrypted computer networks. The present invention is directed to systems and methods for enhancing network security. One preferred embodiment according to the present invention includes a system data store (SDS), a system processor and one or more interfaces to one or more communications channels which may include one or more interfaces to wireless and/or encrypted communications network over which electronic communications are transmitted and received. The SDS stores data needed to provide the desired system functionality and may include, for example, received communications, data associated with such communications, information related to known security risks and predetermined responses to the identification of particular security risks and situations. The SDS may include multiple physical and/or logical data stores for storing the various types of information. Data storage and retrieval functionality may be provided by either the system processor or data storage processors associated with the data store. The system processor is in communication with the SDS via any suitable communication channel(s); the system processor is in communication with the one or more interfaces via the same, or differing, communication channel(s). The system processor may include one or more processing elements that provide electronic communication reception, transmission, interrogation, analysis and/or other functionality. Each interface to a wireless network includes at least one receiver adapted to receive wireless communications; each interface may also, or instead, include one or more transmitters adapted to transmit wireless communications. Each interface to a wired network, if any, include a receiver, a transmitter, both or a plurality of one and/or both; such receivers and/or transmitters are adapted to receive or transmit communication over the wired network to which the interface connects. The system processor and one or more interfaces are typically housed together in a computer system. The SDS, or portions thereof, may also reside in the computer system. In one preferred embodiment, the computer system is a notebook computer or other mobile computer system. In a further preferred embodiment, the system processor, the one or more interfaces and the SDS, or portions thereof, form a host system that may or may not be mobile. In such an embodiment, the system processor may communication with one or more distributed sensing devices. These devices may include a wireless receiver allowing collection of information from the wireless airwaves and include a transmitter allowing communication of the collected information to the SDS for analysis by the system processor. In some such embodiments, the transmitter in each device may be wireless and may allow projection of data into the wireless network to actively thwart potential attackers, for example, by causing interference or locking down access to the network completely. In other embodiments, the host system can receive data regarding communication over the wireless and/or encrypted computer network via a wired interface. Some embodiment may include a plurality of mobile computer systems. The plurality may be adapted to include peer-to-peer wired and/or wireless communication capability and/or to include a communication interface allowing communication with a host system. In one such embodiment including a plurality of mobile computers and a host system, the host system provides the SDS, or a significant portion thereof, shared among the host system and the plurality of mobile computer systems. In another such embodiment including just a plurality of mobile computer systems, the collective local storage capability of the individual mobile computer systems may form the shared SDS. Accordingly, one preferred method of security enhancement includes a variety of steps that may, in certain embodiments, be executed by the environment summarized above and more fully described below or be stored as computer executable instructions in and/or on any suitable combination of computer-readable media. Data associated with a communication transmitted over a wireless computer network is received. A test applied to the received data to determine whether the communication represents a potential security violation; in preferred embodiments, multiple such tests are applied. In one such preferred embodiments, a variety of test types are available including signature test, protocol test, statistical anomaly test and policy test. These tests compare the received data with a variety of configuration information or information derived from such configuration information. Each test alone, or in some predetermined aggregate combination, can generate an alarm based upon the result of the test; in some preferred embodiments, generated alarms include both a type and a severity. In some embodiments, responsive to a generated alarm, a notification may be sent to an administrator. In some instances, the notification can include the type and severity of the generated alarm. In addition to, or instead of, the notification, an active defense can be triggered in various embodiments. In some preferred embodiments, the active defenses include jamming, CRC error generation, random frame transmission, network lock-down and/or dynamic channel change. In some embodiments supporting dynamic channel change, a honeypot trap variation can be included. In some embodiments, the configuration data includes one or more risk criteria, network default data, network policy, performance and/or usage data. This configuration may be received from one or more of a variety of sources including from a configuration file, an interactive data entry interface or a command line or from monitoring the wireless computer network. Some embodiments may further include updating of various types of stored information; different embodiment may update all, none or any combination of the various types of stored information. For instance, some embodiments can update station information associated with the various stations in the wireless computer network based upon the received data. Further, some embodiments can update state information regarding the security of the wireless computer network based upon the received data. In addition, some embodiments can update statistics based upon the received data. Such updates can occur each time data is received, in response to reaching a fixed amount of such update data, in response to reaching a fixed time or the end of a predetermined duration, or some combination of these approaches. Additional advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. Exemplary embodiments of the present invention are now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. As used in the description herein and throughout the claims that follow, the meaning of �a,� �an,� and �the� includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein and throughout the claims that follow, the meaning of �in� includes �in� and �on� unless the context clearly dictates otherwise. Finally, as used in the description herein and throughout the claims that follow, the meanings of �and� and �or� include both the conjunctive and disjunctive and may be used interchangeably unless the context clearly dictates otherwise; the phrase �exclusive or� may be used to indicate situation where only the disjunctive meaning may apply. Ranges may be expressed herein as from �about� one particular value, and/or to �about� another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent �about,� it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. The term �Wi-Fi� is short for wireless fidelity and is another name for IEEE 802.11b. The foregoing discussion of exemplary embodiments may use terminology or make reference to the IEEE 802.11b standard, or other 802.11 variant; however, those skilled in the art will appreciate that systems and methods of the present invention may be applied to WLANs meeting these standards as well as WLANs developed according to competing WLAN standards. The phrase �frame� as used herein shall mean broadly any discretely defined communication transmitted via a computer network and shall not be limited to those specific frame types (control, management, data and error) defined according to 802.11X standards. Architecture of a Typical Access Environment The hardware components depicted in these figures are outlined as follows:
The depicted hardware components include a system processor potentially including multiple processing elements, that may be distributed across the depicted hardware components, where each processing element may be supported via Intel-compatible processor platforms preferably using at least one PENTIUM III or CELERON (Intel Corp., Santa Clara, Calif.) class processor; alternative processors such as UltraSPARC (Sun Microsystems, Palo Alto, Calif.) could be used in other embodiments. In some embodiments, security enhancement functionality, as further described below, may be distributed across multiple processing elements. The term processing element may refer to (1) a process running on a particular piece, or across particular pieces, of hardware, (2) a particular piece of hardware, or either (1) or (2) as the context allows. The sensor devices 230A, 230B depicted in The depicted hardware components include an SDS that could include a variety of primary and secondary storage elements. In one preferred embodiment, the SDS would include RAM as part of the primary storage; the amount of RAM might range from 64 MB to 4 GB in each individual hardware device although these amounts could vary and represent overlapping use such as where the host system 220 supports additional functionality such as integrated with firewall system 145 for providing unified wired and wireless security. The primary storage may in some embodiments include other forms of memory such as cache memory, registers, non-volatile memory (e.g., FLASH, ROM, EPROM, etc.), etc. The sensor devices 230A, 230B depicted in The SDS may also include secondary storage including single, multiple and/or varied servers and storage elements. For example, the SDS may use internal storage devices connected to the system processor. In embodiments where a single processing element supports all of the security analysis functionality, such as seen in It will be understood by those skilled in the art that the different information used in the security enhancement processes and systems according to the present invention may be logically or physically segregated within a single device serving as secondary storage for the SDS; multiple related data stores accessible through a unified management system, which together serve as the SDS; or multiple independent data stores individually accessible through disparate management systems, which may in some embodiments be collectively viewed as the SDS. The various storage elements that comprise the physical architecture of the SDS may be centrally located, or distributed across a variety of diverse locations. The architecture of the secondary storage of the system data store may vary significantly in different embodiments. In several embodiments, database(s) are used to store and manipulate the data; in some such embodiments, one or more relational database management systems, such as DB2 (IBM, White Plains, N.Y.), SQL Server (Microsoft, Redmond, Wash.), ACCESS (Microsoft, Redmond, Wash.), ORACLE 8i (Oracle Corp., Redwood Shores, Calif.), Ingres (Computer Associates, Islandia, N.Y.), MYSQL (MySQL AB, Sweden) or Adaptive Server Enterprise (Sybase Inc., Emeryville, Calif.), may be used in connection with a variety of storage devices/file servers that may include one or more standard magnetic and/or optical disk drives using any appropriate interface including, without limitation, IDE and SCSI. In some embodiments, a tape library such as Exabyte X80 (Exabyte Corporation, Boulder, Colo.), a storage attached network (SAN) solution such as available from (EMC, Inc., Hopkinton, Mass.), a network attached storage (NAS) solution such as a NetApp Filer 740 (Network Appliances, Sunnyvale, Calif.), or combinations thereof may be used. In other embodiments, the data store may use database systems with other architectures such as object-oriented, spatial, object-relational or hierarchical. Instead of, or in addition to, those organization approaches discussed above, certain embodiments may use other storage implementations such as hash tables or flat files or combinations of such architectures. Such alternative approaches may use data servers other than database management systems such as a hash table look-up server, procedure and/or process and/or a flat file retrieval server, procedure and/or process. Further, the SDS may use a combination of any of such approaches in organizing its secondary storage architecture. The hardware components may each have an appropriate operating system such as WINDOWS/NT, WINDOWS 2000 or WINDOWS/XP Server (Microsoft, Redmond, Wash.), Solaris (Sun Microsystems, Palo Alto, Calif.), or LINUX (or other UNIX variant). In one preferred embodiment, the devices 210A�D and/or host system 220 include a LINUX (or other UNIX variant) operating system; although other embodiments may include a WINDOWS/XP (or other WINDOWS family) operating system. Depending upon the hardware/operating system platform of the overall environment, appropriate server software may be included to support the desired access for the purpose of configuration, monitoring and/or reporting. Web server functionality may be provided via an Internet Information Server (Microsoft, Redmond, Wash.), an Apache HTTP Server (Apache Software Foundation, Forest Hill, Md.), an iPlanet Web Server (iPlanet E-Commerce Solutions�A Sun�Netscape Alliance, Mountain View, Calif.) or other suitable Web server platform. The e-mail services may be supported via an Exchange Server (Microsoft, Redmond, Wash.), sendmail or other suitable e-mail server. Some embodiments may include one or more automated voice response (AVR) systems that are in addition to, or instead of, the aforementioned access servers. Such an AVR system could support a purely voice/telephone driven interface to the environment with hard copy output delivered electronically to suitable hard copy output device (e.g., printer, facsimile, etc.), and forward as necessary through regular mail, courier, inter-office mail, facsimile or other suitable forwarding approach. In one preferred embodiment, devices 210A�D and host system 220 can be configured locally or remotely, and configuration can occur through an interactive interface and/or through a command line interface. The interactive interface is accessible locally whereas the command line interface is accessible either locally or remotely. Remote access is preferably granted through the use of a secure shell (SSH) client communicating with an SSH server running on the device or host system. In some preferred embodiments of the present invention, an interactive interface is provided for configuring the access point and various hardware components and supplying a variety of configuration data including thresholds values of various kinds. In one preferred embodiment, an administration program area provides such an interface and allows:
The administration program area, in one preferred embodiment, offers standard windowing interface featuring tabbed pages for easy navigation between configuration functions. From within each of the tabbed pages, an Edit button allows modification of the values. After editing the data, Accept temporarily saves the changes. Commit permanently saves and applies edits (until edited again). Accepted changes persist until the system is restarted whereas committed changes persist until across restarts. Access Point Configuration One preferred embodiment automatically attempts to detect and record all the configured properties for all access points it observes. The settings constitute access point �policies��when access point properties deviate from those recorded, one or more alarms can be generated. The values for an access point can be modified manually to alter the generation of specific alarms. Policies for off-line access points can also be created in some embodiments using an Add feature. The table below provides a summary of several access point properties displayable and/or configurable in some preferred embodiments of the present invention.
For each access point, a station maintenance screen or menu may allow the specification of the stations that are authorized to use it. One preferred embodiment of such a screen or menu, automatically detects all stations within the footprint of the access point's Basic Service Set (BSS) and enters their MAC addresses in an Observed column. Such stations can be indicated as an authorized member of the BSS by selecting them in the Observed column and designating them as Valid. Designated stations are moved to a Valid column. (Stations can, in some embodiments, be designated as invalid by selecting and marking them in the Valid column.) Stations not auto-detected can be manually entered by specifying its MAC address in a Enter New Station input field and triggering an Add Station feature. Access Point Threshold Configuration and Aggregate Station Thresholds Systems and methods according to the present invention generate alerts if network traffic that exceeds thresholds is detected. In one preferred embodiment, all detected or manually configured off-line access points are listed in a Select AP pick list. Thresholds associated with each access point in the pick list can be edited by selecting the particular access point. Such threshold values can be either temporary (until the next restart) or persistent across restarts (until a further edit designated as persistent).
The following table outlines a set of thresholds used in one preferred embodiment that refer to the network characteristics encompassing all stations and traffic in the BSS. In one preferred embodiment, special care must be taken when creating the �byte thresholds� that immediately follow. Several factors govern the values entered for each:
The following table outlines a set of potential thresholds applied to any individual station in one preferred embodiment. If any single station reaches one of these thresholds, an alarm can be generated. The following table outlines a set of thresholds, in one preferred embodiment, applied to the access point itself, and will typically be somewhat more than the Aggregate Station thresholds. In one preferred embodiment, whenever a new access point is detected or manually entered, the specified default settings are applied until it is manually customized. It is assumed that new or unauthorized access points are potential hackers, so it is preferable to set the default thresholds fairly low. Aggregate Station Thresholds The table below outlines a set of thresholds that refer to the combined statistics for all stations in one preferred embodiment. The set of thresholds outlined in the table below apply to any individual station in one preferred embodiment, and will typically be lower than the Aggregate Station thresholds. The set of thresholds in the table below applies to all unauthorized access points in one preferred embodiment.
Some embodiments may allow for self-configuration of some or all of the thresholds discussed above. Such self-configuration could occur through a learning mode in which the systems and methods according o the present invention monitor traffic on the wireless computer network for the first several hours or days after installation. In such a learning mode, alarm notifications can be disabled. It is expected that, in the beginning, the generation of alarms will be very high�hundreds or thousands per day depending on actual network traffic�until thresholds in accordance with the network's normal activity. Once an accurate picture of normal network traffic has been captured, and thresholds are reflective of normal activity, a switch to normal operations mode enables alarm notifications. In one preferred embodiment, a command line interface is provided to configure settings that are not available within the graphical user interface. For example, the IP address of the a hardware component can be changed, its system clock reset or set to �sync� with a network time server. In other embodiments, the graphical user interface and/or the command line interface can allow significant overlap of configuration capability. Further, some embodiments have only one or the other interface type. Finally, some embodiments provide no interactive interface for configuration and are limited to reading configuration data from a file, deriving configuration data from past monitoring of the wireless computer network or otherwise receiving this data. The command line interface in one preferred embodiment can be accessed either on the hardware component such as through a command shell such as the Linux Gnome Terminal or over the network using an SSH (preferably, version 2) client. In one preferred embodiment, a command shell automatically opens on the hardware component after booting. A terminal icon can appear on the task bar at the bottom of the display; clicking the icon opens additional terminal windows. At the command line prompt, a command is entered to launch the command line interface. An SSH client is launched and connected to the hardware component's IP address. The identity of the user making the connection is verified. At the command line prompt, enter the following command to launch the command line interface: Command Line Interface In one preferred embodiment, the screen displays in the terminal window provide five �program areas�:
Opening the network settings program area, the following commands are available in one preferred embodiment: Opening the date settings program area, the following commands are available in one preferred embodiment: Opening the set appliance parameters, configure data management, and restart or shutdown the system area, the following commands are available in one preferred embodiment: Opening the Users program area, the following commands are available in one preferred embodiment:
The functionality of these features can in one preferred embodiment match with like functionality provided in a standard LINUX user management facility. Various methods and functions as exhibited in various embodiments according to the present invention are described above and below with respect to network security enhancement. In some embodiments, one or more processors within architectures of the environments as described above may execute the steps in such methods and provide such functionality. The functionality may spread across multiple processing elements. In other embodiments, any suitable computer readable storage device, media or combination of devices and/or media, including primary storage such as RAM, ROM, cache memory, etc. or secondary storage such as magnetic media including fixed and removable disks and tapes; optical media including fixed and removable disks whether read-only or read-write; paper media including punch cards and paper tape; or other secondary storage as would be known to those skilled in the art, may store instruction that upon execution by one or more processors cause the one or more processors to execute the steps in such methods and to provide such functionality. Vulnerability Assessment and Threat Identification Vulnerability assessment is accomplished by analyzing WLAN traffic, discovering access points and workstations. The system determines how many bytes of data stations are sending and receiving, the mean signal strength for an entire day or the hi/low signal strength for each minute. It can distinguish between network traffic internal to the wireless network and traffic originating from or destined to the physical, wired-network and which stations are the largest senders and receivers of data. The system produces broad summaries of data that report high, low, and mean values for a variety of traffic parameters, and detailed views that show minute-by-minute snapshots of your traffic. Traffic parameters include the breakdown of frame traffic (control, management, data, and error frames) and network routing information. The system determines if any traffic has not been encrypted, users are authenticated, and all hardware is properly configured. The system detects rogue deployments by identifying and locating unauthorized WLANs and ad hoc networks (peer-to-peer networks) that violate company policy and jeopardize security. The system identifies suspicious WLAN traffic across unauthorized channels and frequencies, which can be a common sign of intruders accessing your WLAN or employees abusing their network privileges. The systems and methods according to one preferred embodiment use an audit of existing wireless hardware and perform a survey the air space surrounding the wireless network prior to activating intrusion detection. In this way, a baseline activity level can be determined. Step 1: Hardware Audit Identify every access point in the wireless computer network. Obtain or determine for each its MAC address, Extended Service Set name, manufacturer, supported transmission rates, authentication modes, and whether or not it is configured to run Wired Equivalent Privacy (WEP) and wireless administrative management. In addition, identify every workstation equipped with a wireless network interface card, and record the MAC address of each device. Take note of any physical features in the environment (walls, competing electronic devices such as microwave ovens, cordless phones, etc.) that might interfere with wireless signals. The hardware audit serve as the baseline against which the systems and methods according to the present invention can compare. That is, all access points and wireless stations should be detected by the various embodiments of the present invention. (If an access point or station is not detected, follow logical troubleshooting steps.) On the other hand, it is likely that more devices than expected will be detected. Some of these may be stations or access points not identified or of which no one was aware. Others may be �rogue� devices�surreptitious or unauthorized installations in the network�or harmless equipment belonging to nearby companies, and others may be actual hackers. Once the systems and methods according to the present invention are in intrusion detection mode, all detected access points and stations can be reported. Step 2: Survey Perimeter Preferably a mobile hardware component according to the present invention is walked around the perimeter of the wireless computer network in a powered up state (allowing it to collect data as it is moved), or placed in a central location for 12 to 24 hours to collect a larger amount of data. The benefit of a �walk-around� survey is that it generates a nearly immediate picture of the existing wireless �air space.� The benefit of a �stationary� survey is that over a longer period of time, is greater certainty of detecting devices that only operate intermittently or hackers attempting to penetrate the network off-hours. Repetition of the survey, whether walking or stationary, should occur on all 11 channels. Stationary Data Collection Depending on the size of the wireless network, a hardware component can be placed at the four corners or at intermediate points in the Extended Service Set footprint. At each location, the component should be allowed to passively monitor network traffic for 12-24 hours. Hard copy of network data should be preserved prior to each move. Walk-Around Data Collection Simply walk around the perimeter of the wireless network with the hardware component powered on and open to an overview screen. The various access points and stations within the wireless computer network can be detected. Compare this information with the hardware audit made prior to collecting this data. Repeat this walk-around survey for each of the eleven channels. Step 3: Configure to �Recognize� this Network Each access point detected should be designated as authorized or unauthorized. Each observed station should be designated as valid or not. Step 4: Place Hardware Components in Discrete Locations Throughout the Wireless Network. Leave a component in each location from 1�3 days. Each day, print reports to preserve captured information. Based upon this information, specific access point and station related thresholds can be tuned to distinguish between normal and abnormal traffic patterns. The intrusion detection system (IDS) engine listens to wireless network traffic. Initially, configuration information is received in step 305, typically including network default data and risk criteria. This information can be retrieved from a file, derived or obtained from monitoring the network and/or entered interactively at the outset of the process. The system reads or receives frames from the wireless network instep 310. The received frames are interrogated as follows. The information within the frame is interrogated to determine if a known attack signature has been identified in step 325. Signatures encode datalink layer attack patters as combinations of packet sequences and state. For example, active probing emits a pattern or sequence of network requests. This sequence can be recognized by its packet sequence signature. If the attack signature is identified, the intrusion detection system signals an alarm manager to deliver an alert to the administrator in step 345. If no attack signature is identified, the frame information is passed through a protocol violation engine to determine if the protocol used in the frame is authorized in step 330. Protocol analysis examines whether or not protocol usage is legitimate. For example, emitting a large number of association or disassociation requests in a short interval is not a legitimate use of the protocol. If the protocol used in the frame is outside of the authorized protocol set, the intrusion detection system signals an alarm manager to deliver an alert to the administrator in step 345. If the protocol test passes, in step 335, the IDS checks the frame data for statistical anomalies against the SDS, or a statistics database maintained therein. Anomaly based detection computes such values as the mean, non-zero mean, standard deviation, autocorrelation and peak for each time slice throughout the day. This can be used to create a normalized statistics database for each time slice and user. Current activity is then monitored and compared with the recorded statistics vector. If the difference is larger than a configurable threshold, an alert is generated. Instead of, or in addition to, this approach, a Bayes test can be applied to deduce the probability that the current statistics vector is an attack as opposed to a legitimate sequence. If an anomaly exists, the intrusion detection system signals an alarm manager to deliver an alert to the administrator in step 345. If no anomaly is detected, the system interrogates the frame to determine if a pre-defined policy has been violated in step 340. Policy testing compares the observed activity with a configurable set of activity rules stored in the SDS. For example, a rule can declare that only specific hosts with specific addresses and specific network cards can access the network. If a pre-defined policy has been violated, the intrusion detection system signals an alarm manager to deliver an alert to the administrator in step 345. The tests outlined above and depicted in In some embodiments, one of the above describes test, or another test, can include determining whether a station transmitting in the wireless computer network is in a location that is consistent with its normal location profile. The test may use a station identification and/or mapping process such as described in detail below both to determine the location of a station in order to perform the test and to generate the normal location profile against which to compare. If a station is transmitting from an location not consistent with its profile, an alert can be generated. Alerts can be in the any suitable form delivered to any suitable platform including, without limitation, a screen display to a monitor, a page to a pager, an outgoing voice call to telephone, a SMS message to a mobile telephone, an e-mail message to a valid address, posted to a Web page available via an appropriate Web server or WAP alert to a WAP enabled device. Various types of screen displays and reports may be used to provide information regarding generated alarms. In one preferred embodiment referred to as AirDefense Mobile in U.S. Provisional Patent Application Serial Number TBA entitled �SYSTEMS AND METHODS FOR NEWTORK SECURITY� filed May 20, 2002 bearing 60/381,829 preferred interfaces for reviewing and reporting alarms are described in detail. The contents of this application are hereby incorporated by this reference herein for all purposes. In some embodiment, the outputs of all IDS test are then compared and a confidence level computed in step 345. In one such embodiment, in the case where only a statistical anomaly is detected, it is flagged as a lower level performance alert. In the case where one or more other violations are detected, the alarm is elevated to an intrusion alarm. Some embodiments may use a variety of data stores in implementing the above process to track data across multiple iterations of the process; such data stores can in one preferred embodiment be part of an SDS as described above. Some such embodiments can include a statistics database, a station database and/or a state data store. In such embodiments, some or all of the following steps depicted in In step 315, a station database is updated. This database contains, in one preferred embodiment, per station and per access point records with information describing device address, communications state, timestamps of first and last activity, counts of byte transmissions and local policy information describing whether device is authorized or not for usage in the monitored network. In step 320 state information is updated. State refers to whether or not the device has been seen before and whether or not the station is unauthenticated and unassociated, authenticated, authenticated and associated or unknown state information associated with the wireless computer network. In step 350, a determination is made as to whether a particular statistics interval has been complete. If so, statistics in an SDS are updated in step 355, and processing continues with the next frame in step 310. Otherwise, processing simply continues in step 310 with the next reading or receiving of a frame. A modified and enhance version of the above approach is used where network traffic is monitored from multiple input devices such as with the embodiments depicted in Step 410 is analogous to step 305 from the process of In step 430, a wireless packet frame is received from each input device (e.g., hardware components 210A�D, host system 220 and/or sensors 230A, 230B). Frames are read so that the frame content can be interrogated. Each read frame is interrogated by a multi-dimensional intrusion detection system (IDS) such as detailed above with respect to In step 440, in the case where only a statistical anomaly is detected, it is flagged as a lower level performance alert. In the case where, in addition to the statistical anomaly, one of the other violations has been detected, the alarm is elevated to an intrusion alarm and an alarm manger is alerted in step 444. Other embodiments do not rely on aggregate test outcome but determine alarm status on single test outcomes. Further, some embodiments can use other test types and outcome combinations to determine type and severity of alarms generated. If an alarm is not detected in step 440, a test to see if a predetermined interval for gathering statistics has been reached occurs in step 460. If the end of the pre-configured statistics gathering interval has occurred, the SDS is updated in step 470 to reflect the statistics gathered from the received frames over the interval. Statistics are gathered by monitoring traffic between network nodes, minute-by-minute statistics about BSS frame types and traffic volumes, summaries of transmission statistics for all stations associated with access points, current-minute transmission statistics for all Stations, and detailed minute-by-minute transmission statistics for any individual station in the wireless computer network. Data fusion occurs on a batch basis by aggregating data from multiple databases. This process begins at step 414. The process integrates statistical data from multiple databases that is generated through frame monitoring and intrusion detection engines. This approach provides a methodology for managing data received from input devices such as hardware devices 210A�D and/or sensors 230A, 230B deployed at multiple sites and for aggregating enterprise data at a single central system such as host 220. The Attack and Station Profile database is read at step 418 to begin a processing loop to integrate databases from separate sources. Correlation and pattern recognition is performed at step 420 to update the attack and station profiles in step 424. The processing loop then sleeps at step 428 until the next processing loop interval is to take place based on the pre-configured time interval or trigger. After the alarm manager is signaled in step 444, the attack and station profile database is read in step 448; in this step, existing attacks are queried and existing station security state is queried. In step 450, this data is compared to the newly generated alarm. If it is sufficiently similar, no new external notification occurs in step 454. If it is not, a new notification message is generated in step 454 and console display and/or external messaging of the alarm occurs in step 458. As described above, systems and methods according to the present invention can automatically generate alarms whenever certain events or conditions occur within your wireless network. In some embodiments, an alarm manager providing an interface for viewing can be provided; such an interface is described in greater detail in co-pending �SYSTEMS AND METHODS FOR NEWTORK SECURITY� filed May 20, 2002 bearing 60/381,829. The following table identifies the alarms, alarm subtypes and severities available in one preferred embodiment referred to as AirDefense Mobile. In some embodiments of the present invention, one or more active defense mechanisms may be triggered in response to alarm in addition to, or instead of, the notification process described above. The system may provide active defense from attacks by broadcasting data into the wireless network as well as being able to trap and/or map an intruder's workstation by triangulating the position of the intruder's workstation relative to the wireless network access points. By introducing CRC errors into the wireless stream, the system can actively defeat an attacker that is monitoring the stream for patterns to crack the encryption. CRC errors are introduced by transmitting at the same time as the detected intruder. Due the shared medium nature of the wireless computer network, the cause the packet transmission to be corrupted, preventing the intruder from successfully communicating with the network. By introducing chaf, the system can actively defeat the attacker by placing random frames into the stream so that the encryption pattern becomes undetectable. Chaf is a form of randomized packet transmission that is designed to reduce the probability that a statistical analysis of the packet sequence would result in breaking of the encryption key. This is done by emitting a low-rate background transmission of packets that are emitted using the same characteristics (e.g., address, initialization vector, etc.) of legitimately observed traffic but with a randomized payload. The system can lock-down a wireless network by jamming, a technique to prevent any unauthorized access to the wireless access point by introducing enough noise into the wireless network that workstations cannot physically connect to the wireless network. Jamming is a physical layer transmission that is performed to disrupt all unwanted wireless communications. It is equivalent to introducing a noise signal on top of the unwanted signal transmission such that any receiver would not be able to successfully receive the transmission. In a Physical Device approachOne embodiment would utilize a standalone sensor to implement any of the Active Defense mechanisms. Dynamic channel change can be used to reroute authorized traffic to a different communication channel to avoid an intruder detected on a particular channel. In this approach, a channel change request is transmitted to the access point believed to be compromised and authorized stations use the new channel to communicate with the access point. This approach can also be used to avoid interference causing problems in communication between an access point and its authorized stations. Some embodiments including dynamic channel change may further use a honeypot trap that tricks the attacker into thinking the original channel is still valid and provides the necessary forensic information to identify the attacker. In step 520, configuration information is received. This step is much the same as previously described steps 305 and 410 in In the case that an attack has been detected in 530, processing is passed to step 540 to activate the honeypot trap. A trap thread is started in step 580; the thread initializes itself with the identity of the monitored access point believed to be attacked. This identity typically includes the MAC address, Service Set Identifier, encryption mode, network mode and transmission modes. Once initialized, the thread moves to step 590, the Trap Intruder process. This process is designed to logically fool the identifier attacker into believing communication is still occurring with the original access point. This is accomplished through complete emulation of the original access point's identity and behavior. By maintaining communication with the attacker, a trap is created such that the attacker's physical proximity is assured as long as communication continues. Optionally, a new identity may be assumed such that a weaker or more vulnerable appearing access point can be presented to the attacker. This is done by again emulating access point functionality, but in this case with an identity and set of characteristics that appear vulnerable. This vulnerability appearance may be created through the use of no or weak encryption modes or the appearance of default manufacturing modes with known passwords and user IDs. In step 550 a control packet is sent to the original access point to change channels or suspend transmission while the trap is engaged. This packet encapsulates a message indicating the above request and may be sent in or out-of-band to the access point. In-band refers to over-the-air transmission to the access point's wireless network interface whereas out-of-band transmission refers to transmission to the wired side interface of the access point. Processing in the main loop then returns to attack detection in 530. Triangulation determines the location of an attacker by mapping her relative position within the deployed wireless access points. The mapping and location detection process according to one or more preferred embodiments of the present invention as depicted in The process of In step 620, a lookup occurs in the internal database, such as created via the process depicted in Otherwise, an optional wired network sensor can be queried for the name mapping in step 625. This sensor is preferably deployed within the wired network at a location convenient to sniffing DHCP, LDAP, DNS or other service/name mapping protocols. If found, the internal database is updated in step 640 and execution proceeds to step 645 to query the wireless sensor array, to begin position or location resolution. Some embodiments may not include such a wired network sensor; in which case this step is skipped. If name is still not found, execution proceeds to step 630 where a RARP request is issued. This request asks the receiver population for the IP address of the MAC address in question. If found, the internal database is updated in step 640 and execution proceeds to step 645 to query the wireless sensor array, to begin position or location resolution. If not found, name/IP mapping is not available at current time for this MAC address. In some embodiments, name/IP mapping may not be desired but location or position information is in which case the process can begin in such embodiments at step 645. Step 645 begins the position or location resolution with a query to the wireless sensor array. Each sensor is queried for tracking information on the current MAC address in question. This tracking information identifies whether the MAC is currently observable by a given sensor, the sensor ID, and the signal strength associated with the MAC in question. The sensor array may include not only sensor devices (e.g., 230A, 230B) but also other wireless nodes accessible from this process such as devices 210A-D and/or host system 220. From the data received via the query, the position relative to grid of sensors is calculated in step 650 by computing the �signal strength� distance to each sensor. This distance is computed as the square root of the sum of squares of three sensor signal strength values. The position is then estimated to be within the proximity of the sensors determined to have the smallest signal strength distance to the MAC address in question per the above computation. Once the set of sensors is selected, the position is further refined by selected the position as within the proximity of the sensor within above set with the strongest signal strength. In some embodiments, the process ends at this point with the position information being returned. In embodiments maintaining a position database, this database is updated in step 660 with the position of the MAC address in question. The process then ends at step 670. Encrypted Network Analysis and Management The techniques utilized to monitor WLANs can apply in general to monitoring and analyzing any network link using encryption of the payload or at the IP layer and above rather than just WLANs. In this case, Layer 1 and Layer 2 are observed and decisions made at these layers in terms of signature, protocol, policy and statistical anomaly analysis to assess network health and security. This technique is thus applicable to any network (wired or wireless) exhibiting the above encryption characteristics of the network traffic. In other words, the multi-dimensional IDS implemented per our framework is more broadly applicable to managing and securing any encrypted network. In this case, a WLAN running WEP is one particular instance of an encrypted network. Throughout this application, various publications may have been referenced.

McConnell breathes life back into Senate cyber bill
Thursday - 11/15/2012, 8:12pm EST
The leading Senate Republican is breathing new life into getting a comprehensive cybersecurity bill passed this year.
Sen. Mitch McConnell (R-Ken.) said on the Senate floor that he expects to bring the Cybersecurity Act of 2012 back up for consideration with amendments after the Senate completes work on the Defense Authorization and Intelligence Authorization bills.
"The Senate will hopefully move to a full and open debate of the National Defense Authorization Act," he said. "During the time that the bill is considered on the floor, and I do expect that bill to be subject to an open amendment process, my hope is that the Majority Leader [Harry Reid] will work with me to reach an agreement on allowing a debate on cybersecurity legislation with Republican amendments in order, especially since the ranking members of the Armed Services, Intelligence, Commerce, and Judiciary committees are all co-sponsors of a cybersecurity bill that needs to be considered as part of this debate."
Reid pronounced the bill dead Wednesday night after the Senate failed to end cloture by getting 60 votes. The motion to end cloture passed, but only 51 to 47 — it needed a three-fifths majority to end the filibuster threat.
McConnell reiterated the need to have a full and open debate on the cyber bill, and let lawmakers contemplate amendments.
During the cloture debate, the Democrats were willing to allow amendments. Sen. Joseph Lieberman (I-Conn.), who is a main author of the bill, said Reid was open to a limited amount of amendments, less than 15.
Sen. John McCain (R-Ariz.) said he thinks there is a way to get the bill through the process.
"I still believe if we could have, say, five amendments, that could be voted on and debated, I think we could move forward with this bill. I really believe that," McCain said. "I would like to see right after the vote if we could reach some agreement between the leaders and ourselves that there would be five pending amendments and we could vote on those. I think we have some very significant differences, but the chairman and two co-chairs have worked incredibly hard on this issue and they deserve debate. I hope they would understand we are seeking like five amendments."
But despite this agreement on amendments, there were too many other concerns and not enough support to get to 60 votes.
A blog post by the Heritage Foundation's David Inserra said part of the reason the motion to end cloture didn't get passed is there are too many questions about the regulatory process outlined in the bill and not enough was done to alleviate long-standing concerns about issues such as information sharing.
Inserra said the Obama administration should not issue the planned executive order on cyber.
"[T] he administration should focus on more nimble and less costly solutions, such as information sharing," he wrote. "Information sharing provides the government and the private sector with up-to-date warnings against cyber threats and vulnerabilities while costing nearly nothing. Since both the Senate and House agreed that information sharing is important, sharing, not regulation, should serve as the basis for a meaningful and bipartisan cybersecurity bill during the next Congress."

I thought I would post another tip I have for making a cheap shop filter.
Dust can be a real problem in model shops and this is a useful tool. All you need is a suitable Tupperware or Rubbermaid plastic container, a furnace filter, and one or more muffin fans. The size does not really matter; it is what you can get cheap.
I used a Rubbermaid snap lid container about 24"x18"x6" and a filter about the same size. I cut an opening in the lid just a little smaller than the filter. I just duct tape the filter in place over the hole. On the bottom of the container I mounted four 5" surplus 110-volt muffin fans. You can pick them up cheap, and they are quiet. The four of them will suck a lot of air through the filter.
I just wired them together and mounted the unit to the shop ceiling. Snap the lid on and you are ready to collect that dust!! I check the filter and replace it when it is dirty. I have the collector set up so when I turn on my lights, the fans will start. This is easy to do and really works well. BD.

Kanye West & Kim Kardashian's Cleavage Show Up at Nuggets vs. Lakers Game 7 (Photos)
by Robert Littal | Posted on Sunday, May 13th, 2012
The basketball knowledge of these two are minimal at best.
But, this is about being seen, showing boobs, wearing stilettos and getting in US Weekly.
Mission Accomplished…
That is solid cleavage right there.
All Star worthy?

Revolutionary. Puristic. Radical.
In the form of the production version of the KTM X-BOW, Austrian manufacturer KTM presented its interpretation of a super sports car for the 21st century in 2008. "We wanted to take Colin Chapman's idea of a spartan, lightweight sports car reduced to the bare essentials and transfer it into the new millennium – with as many technological innovations as possible", says KTM CEO Stefan Pierer, reflecting on the development of the first four-wheeled model in the company's history.
The evolution of the revolution
Together with the specialists at Italian sports car manufacturer Dallara, the composites experts at Wethje, the think-tank KTM Technologies and engine partner Audi, what is probably the most exciting super sports car of our times was produced in only 18 months. Of course, the KTM X-BOW takes a large part of its uniqueness from its extraordinary styling. Gerald Kiska and the team at KISKA were responsible for this, creating an iconic modern sports car with their design.
Ready to Race
The new GT makes an even wider, lower, more compact and more powerful impression – the fact that the aerodynamics have been improved in order to generate less drag and even more downforce goes without saying, due, if nothing else, to the KTM X-BOW's racing genes. So even the version of the super sports car from Austria with windscreen and soft top is by no means lacking in purism or radicalness. See for yourself - now without a helmet - that just as much 21st century sports car technology is embedded in this latest model and therefore precisely that racing DNA that makes the KTM X-BOW and the driving experience so special. And that it is always "Ready to Race".

A matzo cracker makes a great base for a pizza that kids and adults will love! Top it with your favorite vegetables and cheese and you have yourself a quick meal.
I love making pizza's out of just about anything, my daughter will eat just about anything if I top it with sauce and cheese (yup, even zucchini pizza). A while back I posted a recipe for my favorite quick Lavash Pizza and someone commented how they do the same with Matzo so when I got requests for Passover recipes, this was the first thing that came to mind.
I personally love red onions and olives on my pizza, but you could slices of bell pepper, baby spinach, mushrooms... you name it! For my daughter I kept it basic, sauce and cheese and she loved it!
Skinny Passover Matzo Pizza
Servings: 4 • Serving Size: 1 pizza • Old Points: 5 pt • Points+: 6 pt
Calories: 230 • Fat: 5.8 g • Protein: 12 g • Carb: 35 g • Fiber: 2.6 g • Sugar: 2 g
Sodium: 349 mg
- 4 fat free matzo crackers
- 6 tbsp crushed tomatoes (I used Tuttorosso)
- 1/2 tsp dried oregano
- 1 cup reduced fat shredded mozzarella (Kosher for religious purposes)
- 2 medium tomatoes, sliced paper thin
- a few thin slices of red onion
- 12 black olives
- 1/4 cup fresh basil for topping
Preheat the oven to 375°. Place a rack on a baking sheet.
Spread 1 1/2 tablespoons of crushed tomatoes on each matzo. Don't put too much or it will get soggy. Sprinkle with oregano then top with tomatoes and onions. Top with 1/4 cup of cheese on each one, olives and bake in the oven until the cheese melts, about 5-6 minutes.

I remember picking strawberries in Wash State and some of the young ladies preferred bending over rather than getting down on the ground to walk on their knees. The view for us guys was always great and invariably we would take a break and get one of the young ladies to fuck. Didn't make a lot of money, but the fringe benefits were pretty good.
