     BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The invention relates generally to the monitoring and auditing of computer security testing. More particularly, the invention is directed a mechanism for auditing, monitoring, scoring, reducing costs, automating retesting and elements of the testing effort, and improving vulnerability/penetration tests.  
      2. Description of the Related Art  
      To improve security in computer systems, it is a common practice for those in charge of security of applications and networks to have a vulnerability/penetration assessment or “ethical hack” performed to test the security. These security assessments are designed to identify and enumerate weaknesses in the security that is in place, by implementing attacks and the providing solutions for improving security. However, security assessments are costly and are not wholly audited or scored for performance, with the result that there is no way to determine the effectiveness of the security assessment, and thereby, no true way to gauge the actual effectiveness of the security.  
      Thus, there is a need for a system and method for monitoring and grading security assessments. The solution should be a scalable and easily integrated into the assessment process and testing architecture. In addition, the solution should be effective at auditing, managing, scoring/ranking/benchmarking application and network security and vendor performance, while also improving, logging, leveraging, and automating portions of the overall process. To illustrate the current state of the art, set forth below is a detailed background discussion related to the practice of web application security assessments, a particular type of client-server application.  
      Familiarity with the following terms will aid the reader in understanding the background discussion and the detailed description of the invention.  
      Applet: A Java® program embedded in a web page and executed in a Java®-enabled web browser.  
      Web Browser: A client application connected to the World Wide Web that requests resources from a web server, usually for the purpose of displaying the requested resources. Examples of browsers are Internet Explorer and Netscape Navigator.  
      Proxy: A proxy is an intermediary program which acts as both a server and a client for the purpose of making requests on behalf of other clients. Requests are serviced internally or by passing them on, with possible translation, to other servers. A proxy must implement both the client and server requirements of a specification. A “transparent proxy” is a proxy that does not modify the request or response beyond what is required for proxy authentication and identification. A “non-transparent proxy” is a proxy that modifies the request or response in order to provide some added service to the user agent, such as group annotation services, media type transformation, protocol reduction, or anonymity filtering. Except where either transparent or non-transparent behavior is explicitly stated, the HTTP proxy requirements apply to both types of proxies.  
      Cookie: A packet of information sent by an HTTP server to a web browser and then sent back by the browser each time the browser accesses that server. Cookies can contain any arbitrary information the server chooses and are used to maintain state between HTTP transactions. Cookies are not visible to the browser user.  
      Directory: A simulated file folder on disk.  
      GUI (Graphical User Interface): A graphics-based interface that incorporates icons and/or pull-down menus and user interaction with the GUI.  
      CGI (Common Gateway Interface): A standard for running external programs from a HTTP server.  
      CGI Script: A small program written in a script language such as Perl that can be invoked through a request to the web server.  
      ASP® (Active Server Pages): A scripting environment developed by Microsoft Corporation. ASP® allows HTML, scripts, and ActiveX components to be combined to create dynamic web pages.  
      HTML (Hypertext Markup Language): A hypertext document format used on the World Wide Web.  
      DHTML (Dynamic HTML): An extension of HTML, created by Microsoft Corporation. DHTML gives greater control over the layout of page elements and the ability to have web pages which change and interact with the user without having to communicate with the server.  
      XML (Extensible Markup Language): An initiative defining an “extremely simple” dialect of SGML suitable for use on the World-Wide Web.  
      SGML (Standard Generalized Markup Language): A generic markup language for representing documents. SGML is an International Standard that describes the relationship between a document&#39;s content and its structure. SGML allows document-based information to be shared and re-used across applications and computer platforms in an open, vendor-neutral format.  
      JavaScript®: Designed by Sun Microsystems and Netscape Communications Corporation as an easy-to-use scripting language of Java® programming. JavaScript® code can be inserted into standard HTML pages to create interactive documents.  
      HTTP (HyperText Transfer Protocol): The client-server TCP/IP protocol used on the World Wide Web for the exchange of documents.  
      HTTPS (HyperText Transfer Protocol, Secure): A protocol for handling secure transactions that involves the use of SSL underneath HTTP.  
      HTTP Server: A server process running at a web site that sends out web pages in response to HTTP requests from remote browsers.  
      HTTP Client Agent: A client is a program that establishes connections for the purpose of sending requests. A user agent is a client which initiates a request. These are often browsers, editors, spiders (web-traversing robots), or other end user tools.  
      HTTP Session: Allows the server to maintain state between different HTTP requests. The HTTP server knows which session to associate with the request because the browser sends the session ID as part of the request. This can either be done with a cookie or by adding a parameter to the request URL.  
      LRI (Local Resource Identifier): The location of the resource relative to the hierarchical structure of the server.  
      URL (Uniform Resource Locator): A compact string representative of resources available via the network. A URL has the form &lt;protocol&gt;://&lt;server name&gt;&lt;LRI&gt;&lt;? optional parameters&gt;.  
      Process: A self-contained operating environment that behaves as if it is a separate computer. A Java® virtual machine is a Java® interpreter that converts Java® byte code into machine language one command at a time and then executes it.  
      SSL (Secure Sockets Layer): A protocol designed by Netscape Communications Corporation to provide encrypted communications on the Internet. SSL is layered beneath application protocols such as HTTP, SMTP, Telnet, FTP, Gopher, and NNTP, and is layered above the connection protocol TCP/IP.  
      One source of vulnerability for computer systems connected to the Internet is web applications. A web application is a client-server application. The client makes HTTP requests to the server, and the server provides responses based on the input provided by the client and the application logic and data within the application. Web developers often wrongly assume that the user input is constrained and cannot be manipulated, thus obviating good programming practices that requires vetting all user input. This assumption is founded upon an incorrect understanding of the security that the SSL (secure sockets layer) protocol attempts to provide, as well as upon the mistaken notion that user input manipulation attacks require breaking SSL (which is not believed to be feasible or practical if correctly implemented using 128-bit keys).  
      Proxies are standard well-known Internet technology components that allow companies to funnel traffic through a single point. This provides a number of useful characteristics and capabilities (e.g., caching for increased download speed, anonymity, access control, filtering, IP address space, etc.) Various types of proxies exist. For gateway proxies, the proxy is an SSL end-point; essentially a separate SSL session is set up between each client/server pair (e.g., browser/company proxy, company proxy/reverse proxy, etc), so at each proxy the communication is fully decrypted then re-encrypted with a new key known by the communicating pair. Proxies are intermediary programs which act as both a server and a client for the purpose of making requests on behalf of other clients. Requests are serviced internally or by passing them on, with possible translation, to other servers. A proxy must implement both the client and server requirements of this specification.” 
      In the past, “hackers” have re-engineered proxies to create a proxy tool such that the data passing thru the proxy and being decrypted and then re-encrypted is trapped before being forwarded. This allows the hacker to manipulate the data before being transmitted to the server. The proxy tool allows the attacker to exploit the above assumptions and manipulate the data being supplied to the server. If the code does not properly vet the ‘munged’ user input, it may be possible to exploit coding flaws. Attacks may result in the attacker obtaining unauthorized access to data; masquerading as another user; executing fraudulent or unauthorized transactions, such as embezzling money, etc.  
      While conducting vulnerability/penetration assessments is often an effective method of identifying security flaws, an existing problem in contracting this type of effort is that neither the client nor the people managing the effort understand the under-the-cover details of the effort. Therefore, it is a simple exercise for the person or company performing the ‘ethical hack’ to either purposely fudge the effort and cost or simply provide substandard and inconsistent assessments. The result can be an overpriced (comparatively high profit margin) service of possibly poor quality.  
      To reduce costs and improve performance, several companies have attempted to automate some security assessment components. In their own right, these automated security assessments test specific weaknesses in the system, but due to the changing and the dynamic nature of the Internet, complexities in the associated applications and Internet landscape (and related public and private networks) these security assessments are currently not comprehensive, not on par with manual “ethical hacks”, and are not likely to ever overcome complexity and various other dynamics necessary to completely automate the effort. Furthermore, these automated hacks may provide a false sense of security due to their inability to take into account slight variations on hacking methods.  
      Accordingly, the security assessment process cannot currently be completely automated, and it is likely that it never will be able to be completely automated. However, regardless of the asserted capabilities of automated security assessments, both automated and manual security assessments should be monitored, and at times audited and scored for performance. To improve service and security as well as reduce costs, the present invention provides a mechanism to access all data being communicated between the tester and the web application system, as well as actions being taken by the tester, thereby allowing an auditor or other interested user to non-intrusively monitor/shadow and record the manual and automated hacking efforts during a security assessment.  
     BRIEF SUMMARY OF THE INVENTION  
      In a first aspect, the invention provides a system, method, and apparatus for managing, monitoring, auditing, inspecting, analyzing, cataloging, scoring, and automating vulnerability testing efforts and elements of testing, as well as reducing cost, improving quality and consistency, increasing assurance and confidence in the assessment effort, while improving the effectiveness of vulnerability/penetration assessments in general. The invention includes an elegant, unobtrusive, and scalable method, system, and apparatus that is easily integrated into the assessment and penetration testing process for accessing data communicated between the testing entity and the application system, and which allows for the deciphering and decoding of data that is ciphered and/or encoded. The invention then leverages this data by integrating and applying various technologies (e.g., parsers, storage, database, encryption tunnels, secure remote access, access control, various logic, interpreters, displays, proxies, automated scanning, and signals and alerts) to fulfill the objectives outlined above as well as others, including the following examples: 
          Determine, record, and signal whether security assessment work is being performed, or whether an automated tool is being used     Audit the security assessment effort;     Monitor the security assessment effort;     Assess the security assessment effort;     Assess the scope of the security assessment;     Assess whether there is over-charging for the security assessment;     Provide auditors and other interested authorized and authenticated users with the ability to monitor security assessments in real-time;     Provide auditors and other interested authorized and authenticated users with the ability to review security assessments after the assessment is completed;     Provide auditors and other interested authorized and authenticated users with the ability to easily make ad-hoc queries about either an assessment currently in progress or a past security assessments;     Provide signals and alerts regarding the testing effort (e.g., inactivity, automated scanner use);     Provide auditors and other interested users with information indicating the completeness and efficacy of the security assessment;     Provide auditors and other interested and authorized users with built-in reports and the ability to generate ad-hoc reports regarding security assessments;     Provide the means to capture security assessment techniques and methodologies and identify vulnerable materials;     Catalog pages/scripts tested by security assessments;     Create a log of the security assessment testing efforts;     Automate retesting efforts as well as elements of the testing effort;     Benchmark vendor testing efforts for a particular application;     Benchmark risks across applications; and     Generate reports associated with different aspects of the assessment.        

      To improve service and security as well as reduce costs for security assessments, the present invention provides a mechanism to non-intrusively monitor or shadow manual and automated security assessments, including: capturing testing activities and data, providing real-time display of testing activities and data, storing testing activities and data, generating and displaying metrics associated with testing data, and ranking application security and vendor capabilities.  
      Thus, in one aspect, the invention is directed to a method, system and apparatus for managing, monitoring, auditing, improving and scoring client-server application vulnerability/penetration assessments, as well as automating retesting efforts and supplementing and replacing elements of the initial security assessment. The invention includes data access and collection functionality, whereby an elegant, non-obtrusive method, system, and apparatus are easily integrated into the assessment process. The invention is scalable and provides access to all data communicated between the Testing Entity and the Application System. The invention further includes deciphering/enciphering, decrypting/encrypting, decoding/encoding functionality, where necessary, for performing these respective functions on the data flowing between the testing entity and the application system.  
      Under additional aspects, the invention includes capture, and store data functionality that captures, stores, and logs all encrypted and unencrypted data flowing between the testing entity and the application system. Thus, the invention stores and catalogs both deciphered raw unaltered and altered data (e.g., HTTP request and response messages), and parsed data. Also, the invention is able to store and/or log all data flowing between the testing entity and the application system, including connection and handshaking (e.g., web application requests and responses for content not requiring authorization and for content requiring authorization).  
      Under another aspect, the invention includes functionality that parses data, stores parsed data, analyzes data, and builds databases, including parsing all requests and responses, and intelligently storing the requests, responses, and parsed data (e.g., for web applications, URLs, paths, script names, HTTP Request and Response Headers, POST and GET parameters and values, Identification and Authentication credentials, session token names and values). The invention can then create a database of the vulnerability testing effort (e.g., for web applications, the database may include: all Pages/Scripts Requested, for all accounts and authorized/unauthorized requests; all URLs; all requested Pages/Scripts and actual Requests and Responses for each test account; all Pages/Scripts requested not associated with an account; aggregate of all submitted parameters for each Request/Script/Page and all values for each; all parameters submitted for a particular Request/Script/Page for each account and the associated values for each parameter; scripts requested, parameters included with each request and all values for each parameter; results for each Request). The invention can allow for the generation of a superset vulnerability database of vulnerable material that consolidates all the vulnerable material requested from all of the tests conducted using an implementation of this method and which can be leveraged to enhance the testing effort.  
      Under yet an additional aspect, the invention includes displays and interpreters that allow real-time and offline monitoring and viewing of all aspects of the security assessment. This aspect includes providing interested and authorized users the ability to monitor the testing effort in real-time by displaying the data flowing between the testing entity and application, as well as actions being taken by the testing entity (e.g., in the case of web applications, providing a view of both the deciphered raw HTTP Requests and Responses as well as a separate view of the rendered and/or interpreted Requests and Responses, and parameter manipulation). Thus, the invention provides auditors and other interested, authorized and authenticated parties with a real-time view of what the tester is doing and seeing. This invention also displays various real-time signals and alerts that provide authorized and interested users with information about the present state of the vulnerability testing effort (e.g., whether work is being performed, whether an automated tool is being used, area of the application system being evaluated, and the like). The invention further is capable of displaying other performance parameters, requested pages, and the like.  
      Under an additional aspect, the invention includes an analyzer functionality that applies logic and rules to the data being communicated between the testing entity and the application system, to thereby yield information about the data itself, the application system, and the testing effort, including the state-of-the-art, the vendor capabilities, trends, and statistics. The invention can then apply this to a data/information reporting functionality that will allow authorized and interested parties to easily make ad-hoc and pre-canned queries against the stored data for either the test currently in progress or a past test. Thus, the invention can provide interested parties with reports containing various information indicating the completeness and efficacy of the test(s), including: statistics, comparison data, directories, scripts tested, accounts and passwords used, all parameters used, and all submitted values for each page/script. This provides authorized interested parties with the ability to compare tests, applications, and vendors capabilities, and further allows authorized interested users with built-in reports regarding the testing effort and benchmark risk posture. In addition, authorized users are provided with statistical reports that may list the attacks against each page/script and associated parameters for each by User ID and in aggregate.  
      Under another aspect, the invention includes feedback loop and process improvement functionality that allows for the capturing and storage of assessment techniques and methodologies. This aspect allows for the capturing and building of a database of vulnerable material. This can also enable an automation and testing engine that can be leveraged by authorized testers to streamline and improve the test effort. This allows authorized users with the ability to re-run previous tests, such as replaying tester requests and or re-running scans.  
      These and other features and advantages of the present invention will become apparent to those of ordinary skill in the art in view of the following detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF THE INVENTION  
      In the following detailed description of the invention, reference is made to the accompanying drawings which form a part of the disclosure, and, in which are shown by way of illustration, and not of limitation, specific embodiments by which the invention may be practiced. In the drawings, like numerals describe substantially similar components throughout the several views.  
      The invention provides a mechanism for non-intrusively auditing vulnerability/penetration test assessments and similar computer security tests by capturing, presenting, displaying, inspecting, monitoring, and analyzing data flow in a client-server application (such as a web application) as well as in network penetration/vulnerability tests. The method, system, and apparatus of the invention provides users, (managers, hired auditors, application owners, CISO&#39;s (chief information security officers), etc.) with a mechanism to non-intrusively oversee in real-time the security test effort, determine whether work is being performed for billed hours, capture the results of the effort for off-line review and comparison across vendor efforts and applications, improve quality, measure and evaluate the level of effort and completeness, and capture methodology that can be pushed out to other vendors. Where possible, the method, system, and apparatus of the invention are also be scalable, allowing multiple efforts to be monitored, audited, and analyzed concurrently. Additional embodiments of the invention provide capabilities to improve the efficacy and efficiency of the vulnerability test effort by providing various data, information, and tools for the tester. For clarity, the following detailed description is outlined into two principal sections: auditing of client-server application vulnerability/penetration testing, and auditing of infrastructure vulnerability/penetration testing.  
      Under the invention, the tester can be any element that actuates the application, generating requests and responses, such as an automated vulnerability scanner (e.g., whisker, nessus, nikto, appscan, kavado), consultants generating requests and associated responses, or some other tools used by a consultant to activate the application. Automated scanners include any machinery, software, or tool that actuates the application (usually generating requests to the application) and may be designed to determine and enumerate vulnerabilities for the application.  
      A consultant is any one or a collection of people activating the application, or generating any type of requests against the application. The requests can be generated manually or through the use of some tool. Other tools that might be testing entities can include any mechanism used to actuate the application for generating requests in order to identify and enumerate potential vulnerabilities existing within the application system.  
      As applied to client-server application testing of the invention, auditing capabilities are fulfilled by providing the means to: capture all client-server transaction data; decipher where necessary captured data; and allow multiple users or auditors (e.g., managers, hired auditors, application owners, chief information security officers (CISO&#39;s), etc.) remote access for viewing the exchange of transaction data as well as resultant rendered pages. These auditing capabilities include: capturing, deciphering, presenting, displaying, inspecting, monitoring, and analyzing data flow in the client-server application test to non-intrusively watch-over in real-time the vulnerability test effort; determining whether work is being performed for billed hours; capturing the results of the effort for off-line review and comparison between vendor efforts; improving quality; measuring and evaluating the level of effort and completeness; and capturing methodology that can be pushed out to other vendors.  
      An unlimited number of different client-server applications fall within the scope of the invention. In the detailed description that follows, an exemplary embodiment of an HTTPS web client-server application is used for illustrating the principles of the invention. However, it should be understood by one of ordinary skill in the art that the principles of the invention are applicable to other client-server applications and other embodiments of the illustrated HTTPS web client-server application. For convenience, the following detailed description for the client-server web application principal section is outlined into the following sub-sections: (1) Functional Features; and (2) Architecture.  
      For each HTTP transaction, the invention allows the auditor to view, in real-time or at a later time, the raw request and response data as well as the rendered page. Additionally, each request and response will be stored. Further, the request and response is parsed, extracted, grouped, aggregated and stored according to various logic functions. The invention also provides a facility for saving request and response transactions so that the transactions can be explored at a later time. Further, the data parsed from the collection of requests and responses as well as generated information is stored in such a way as to allow the auditor to group data in various ways or make ad-hoc queries. For example, an auditor might query the database for all the values submitted for a particular parameter submitted to a particular server script (e.g., ASP, servlet, JSP, etc.), thus providing the auditor with one ad-hoc data point for scoring the testing effort.  
      In general, the invention includes some or all of the following: (A) a mechanism to extract, decipher, view, and capture actions and activities being conducted by the tester and data communicated between the application and the tester; (B) a data collector that collects and stores transaction data (e.g., the entire request and response is captured, including the URL, HTTP headers, and all variable parameters and values); (C) a database and directory for storing data and accessing organized stored data; (D) an analyzer that inspects the data being captured and generates information based on logic, other inputs, and the captured data; (E) a logic component, where necessary, that interprets transaction data and enables the data to be rendered; (F) a graphical display and/or interfaces that provides a mechanism for viewing in real-time ‘raw’ transaction data, rendered or interpreted data, and data generated from the analyzer as well as display data, rendered data, and other information stored in the database (e.g., for selected captured transactions, the raw HTTP request and raw HTTP response page served to the tester based on the tester&#39;s request will be displayed, as well displaying the rendered page, thusly providing the interested party a view into the effort); and (G) attack profiles for commercial and publicly-available scanners allowing the method, system, and apparatus of the invention to identify automated scanner use.  
      The invention comprises several embodiments for each of the components. In particular, the data capture can include one or more of the following mechanisms: (1) an intermediary (proxy) with all data passing through the intermediary—in this embodiment, the intermediary implements all functions of both an HTTPS client agent and HTTP server agent, and for SSL communication, the intermediary serves as an SSL end-point; (2) a sniffer that can passively extract all data being communicated between the application and tester—in this embodiment, the sniffer is provided with the origin server (or reverse proxy), client certificate(s), and associated keys; and (3) computing modules placed within the testing entity or application system environment (e.g., software components placed on the testing entity computer or application system—web or proxy server—or appliances integrated into the testing entity or application system).  
      Functional Features  
      The invention provides functional features or capabilities including: real-time view into the HTTP request/response transactions and page rendering (essentially quantifying work or showing that work is being performed); capture and collection of the transaction data (essentially gathering the data necessary to qualify the work being performed); storage for retaining collected data, generated information, and metrics; interpreters for rendering data; logic for analyzing the data and effort, logic for measuring the effort, logic for scoring the effort, logic for generating metrics, logic and profiles to determine whether automated tools are generating the request stream; secure storage of collected data and generated information; access control; secure remote access; and the ability to concurrently audit multiple application tests concurrently.  
      One functional feature is data access and capture. Embodiments include: (1) extracting data from a point between the tester and server by either passively extracting the data ‘off the wire’, or acting as an intermediary relaying requests and responses; (2) providing computing modules within the testing entity or application system environment: either appliances with access to the communicated data (e.g., connected to a hub), or software that can be installed on the tester&#39;s platform (e.g., a computer where browser or proxy is running), or the application system (e.g., a reverse proxy, web server, application server, etc.) or a combination of the above. Where the data collector is physically separated from other functional elements of the invention, these mechanisms may either store the data locally and/or securely transmit the accessed data back to a central processing and storage engine and/or allow. Further, these components allow authorized, authenticated auditors to log into the computer and view the actions of the tester and the results of those actions in real-time (essentially the auditor is viewing the tester&#39;s display (3) a combination of the foregoing.  
      Another functional feature of the invention is the security provision, including: the ability to control, protect, and govern access to the various components (e.g., users, source and destinations, connect, authenticate, scan, target application system, and view); ensure the confidentiality and integrity of data collected and information created; and protect the data and information. The invention includes authentication, encryption, authorization, and other security functional elements to provide the necessary security.  
      Another functional feature of the invention is the provision to allow the auditor to view in real time the HTTPS transactions in raw data form as well as the resultant rendered page. An embodiment of the invention provide this capability by allowing the auditor to remotely connect to the testers platform and view the actions of the tester as well as the HTTPS transactions and rendered results (e.g., connecting to the tester&#39;s platform, essentially exporting the tester&#39;s GUI). Alternatively, data may be securely streamed to a central processing and storage engine and/or the auditor&#39;s computer where the necessary logic elements present the raw data as well as rendered resultant pages and some of the actions of the tester (i.e. with access to the data and other logic and mechanisms, the actions of the tester can be deduced). Another embodiment allows real-time viewing of the HTTPS transaction data by allowing the auditor to remotely connect to a system where captured data is displayed and rendered.  
      Embodiments include the following mechanisms for acquiring the captured data either at the tester&#39;s computer or application system, or at a point somewhere between the tester and the server. For data acquired at the tester&#39;s computer or application system, this data is securely streamed to the system and apparatus of the invention. For data captured at a point somewhere between the tester and the tested system, the data may be acquired by passively sniffing the data off the wire or communication channel. Alternatively, an intermediary may be used that performs all of the functions of both an HTTPS client agent and HTTPS server agent; for SSL, the intermediary would be an SSL end-point for both the tester-to-intermediary proxy and for the intermediary proxy-to-server.  
      Another functional feature is the ability to identify the use of automated scanning tools. Embodiments of the invention contain automated scanning signatures that provide this capability.  
      Architecture  
       FIG. 1  shows a block diagram of functional elements according to one embodiment of the invention. The invention includes a system, network, application, application system, or other structure (application system  27 ) to be tested by a security assessment. An application client  3  (e.g., browser) for use by the tester is able to communicate with application system  27  via a communications link or channel  216 . Application client  3  includes any of the following: a web browser (e.g., Internet Explorer), a tester&#39;s proxy (e.g., FormScalpel), a computer hosting a web application scanning tool (e.g., AppScan) that makes HTTPS requests, or an appliance that performs automated web application scanning as is known in the art.  
      One category of functional elements depicted within  FIG. 1 , include data collectors, which acquire HTTPS transaction data  1  communicated between application client  3  and application system  27 . An embodiment of the invention uses one or a combination of data collectors. The data collectors of the invention can be logically grouped by the physical location where the data is acquired: at the application client  3  or application system  27 , or at some point between the application client  3  and the application system  27 .  
      The tester data collector  37  for this embodiment is comprised of software or a system collocated with the application client  3 . Tester data collector  37  is installed on the tester&#39;s testing platform prior to the execution of the security test, and captures all HTTPS transaction data. Alternatively, or additionally, a system data collector  38  may be installed at the application system  38 . The captured data  314  may be stored and processed locally and/or sent data through a secure channel  310  to a central mechanism  312  comprising functional components handling processing, storage, and display ( 5 ,  6 ,  9 - 22 ) or to auditor  39 .  
      The functional components of central mechanism  312  include security control  5  for controlling remote access and data transmission. Displays  6  may be provided for displaying raw requests and responses, rendered pages, reports, and the like. Other functional components may include a scanning engine  9 , a session ID generator  10 , a database query interface  11  for interfaces with databases  12 . Databases  12  include a superset vulnerability database  13 , a test database  14 , a canned report query database  15 , a certificate store  16 , scanner signature database  17 , and user database  18 . Other functional components can include interpreters  19 , a data analyzer  20 , a data parser  21 , and a raw data storage  22  for receiving and storing collected data  314 .  
      The proxy data collector  23  for use in some embodiments of the invention is comprised of software or a system that is located between the application client  3  and the application system  27 . The proxy data collector  23  either passively extracts the data from communications channel  216  using a sniffer  8 , or actively captures the data using an intermediary proxy engine  7 . Sniffer  8  is loaded with necessary certificates and keys, allowing for the deciphering of SSL traffic on communications link  216 . Correspondingly, the intermediary proxy  7  is loaded with certificates for communications with both the application client  3  (browser or other proxy) and the application system  27  (web server, reverse proxy, etc.). Intermediary proxy  7 , in addition to capturing and where necessary deciphering data, provides all of the functions of an HTTPS client and HTTPS server, relaying requests and responses between the application client  3  and the application system  27 . The proxy data collector  23  also provides the collected data  314  to the processing elements of the invention ( 5 ,  6 ,  9 - 22 ) or to the auditor  39 , or both. The proxy data collector  23  may also have additional connections to other functional elements.  
      A tester  40  may interface with the intermediary proxy  7  in the following ways: using the intermediary proxy  7  as the test proxy; turning on proxying within the application client (browser, proxy, scanner) and setting the appropriate IP address and port of the intermdiary proxy  7 ; or seeing the intermediary proxy  7  as the origin server, hard coding the real origin server IP address and port into the intermediary proxy  7 .  
      Within the processing elements, an analyzer  20  examines the captured data  314 , and based on various internal logic as well as input from scanning signatures  2 , generates additional information that is also stored in a database as well as presented to a graphical display  6 . Embodiments of analyzer  20  include logic to correlate data providing additional insight into the testing effort. For example, analyzer  20  identifies particular sessions and the associated requests and responses with a user ID used to establish the session. The analyzer  20  does this for each user ID used for establishing a session. The Analyzer  20  then examines the sets of requests for each user ID and determines which requests were made and not made for each user ID. This can be used to determine whether forced browsing was comprehensively tested.  
      The graphical display  6  provides the auditor  39  with a visual interface to display all elements of the testing effort(s) in real time as well as allow the auditor  39  to inspect the data and information at a later time. Other authorized, authenticated uses that might be given access to the displayed data include managers, application owners, businesses  41 , and the testers  40 . Data and information that the graphical display  6  displays includes, tests  1 ,  2 , . . . n, being audited, raw HTTPS transaction data (requests, responses, parameters, variables and values), rendered result pages/page-sets, reports  32 , alerts  31  (e.g., use of an automated scanner), alarms (e.g., no testing activity), ad-hoc queries of data stored in the database  12 , configuration options for alerts and alarms, and other information and stats  33 . The graphical display  6  has connections to various components including all databases, the analyzer  20 , data collectors  23 , and interpreters  19 . The interpreter  19  provides the processing and logic necessary to create rendered pages.  
      The database  12  contains automated scanner signatures  17  allowing the invention to determine when automated tools are being used and signal the auditor  39 . The scanner signatures  17  are either compiled using the invention, or provided by the owner of the scanner.  
      Embodiments of the invention provide remote access  5  capabilities, allowing one or more authorized users to connect to various components, systems, and/or functional elements. This may be via encrypted communications  36  between the authorized users and central mechanism  312 , and the authorized users may also have remote connection  34  to the application client  3  and/or remote connection  35  to the application system  27 . Communications between the application system and central mechanism  312  include superset vulnerability scans  24  passed on by the central mechanism  312 , normal requests from proxy and responses from server  25 , and automated retest scan requests and responses  26 .  
       FIG. 2  shows a logical diagram of the functional components for a particular embodiment of the invention.  FIG. 2  illustrates the general relationship between the functional components and their general interaction, and also illustrates the physical relationship between the components.  
      During security testing, data communicated between the testing entity&#39;s  42  application client  3  and the application system  27  in  FIG. 2  is represented and manifest in two separate communication links:  46  and  72 . Communication link  46  represents the link between the application client  3  (e.g., a browser, another proxy, or scanner) and the intermediary proxy  63 . Communication link  72  represents the communication between the intermediary proxy  63  and the application system  27 . Where SSL is being used, the intermediary proxy  63  acts as two SSL endpoints.  
      The intermediary proxy  63  is comprised of conventional functionality found in HTTP proxies as well as functionality found in proxies built for hacking web applications, e.g., ability to trap and modify request and response data, a user interface  64 , remote access  65 , access control  67 , functionality contained within standard HTTP clients (e.g., interpreters, etc.), and encryption/decryption capability  66 . The intermediary proxy  63 , although shown together with various other functional elements of the invention, may or may not be collocated with other functional elements of the invention.  
      The intermediary proxy is installed in any network point that is accessible to the testing entity, the application system, and in most cases authorized interested parties, examples include: anywhere in a customer&#39;s environment with appropriate connectivity access to the web application system, the testing entity, and authorized interested parties within the testing entity environment with appropriate connectivity access to the web application system; the testing entity, and authorized interested parties; third party service providers with appropriate connectivity access to the web application system, the testing entity, and authorized interested parties. The intermediary proxy has access to all data flowing between the testing entity and the application system and either procedural or technical mechanisms can be used to force all data through the intermediary proxy. The intermediary proxy may act as an link endpoint and include web application proxy hacking functionality that can be leveraged to perform web application testing tasks, including: trapping all requests before being relayed to the application system; trapping all responses before being relayed to the testing entity; allowing automated parameter manipulation and manual parameter manipulation by authorized interested parties.  
      Additionally, for the intermediary proxy implementation, either the testing entity may be configured to proxy all requests through the intermediary proxy, or the target given to the testing entity is the address of the intermediary proxy. In the case where the testing entity is configured to proxy all requests through the intermediary proxy, the HTTP protocol specification includes an algorithm for sending messages through an intermediary, and the web application clients and servers inherently support this capability. Furthermore, the HTTP specification also provides for ‘chaining’ proxies, so where a testing entity is using a proxy, the testing entity will be required to use a proxy that supports chaining and to configure the testing entity proxy to proxy through the intermediary proxy.  
      In the case that the testing entity is provided with the IP address of the intermediary proxy as the target, and the testing entity is not configured to proxy, this may be done with or without providing the testing entity with the knowledge of the real origin target. The Intermediary Proxy may then be configured (hardwired) to relay the requests coming from the particular testing entity to the origin application and the responses from the origin server back to the testing entity.  
       FIG. 3  shows a high-level flowchart of the operation of the invention. The flowchart begins with preparation step  171 , where mode of operation decisions and configuration settings are made, as well necessary input is provided (e.g., certs, users, target, tester IP address and port, etc.)  
      Step  172  shows the start of the application assessment wherein the tester begins to test the system.  
      As data is communicated between the application client and the application system the data is accessed and acquired  173 .  
      If SSL or encoding is being used (step  174 ), the data is decrypted/decoded in step  175 .  
      If the data collector is not physically collocated with the rest of the invention, the data is stored locally and/or securely transmitted to the processing elements of the invention in step  277 .  
      In step  176 , the accessed, acquired, and clear-text data is then permanently stored.  
      The acquired data is then available for view and displayed if the particular functional display is in focus  177 .  
      The raw acquired data is then processed by the interpreter  19  in step  178  and also available for view and displayed if this particular display function is in focus.  
      In step  180 , the clear-text data is then processed by the analyzer  20  and various information is determined regarding work load and this data is available for view and is displayed if the this particular functional display is in focus in step  181 .  
      The clear text data is then parsed in step  182 . Together with the parsed data, the data set up as part of the preparation phase in step  171 , the session creation and determined and its state is maintained in step  183 .  
      The parsed clear-text data, knowledge of the session, and other information, together with various logic and rules are then analyzed in step  184  and used to build various databases in step  185 , based upon results of all tests conducted  186 , and automatic scanning engine signatures  187 .  
      The databases are then available to generate stats and reports for viewing on the display  189  or as reports  190  available to users.  
      The acquired data and generated information can then be leveraged  192  for re-running tests  193 , automating or simplifying retests  194 , running superset vulnerability scans  195 , running adhoc quiries against the acquired data  196 , and for issuing pre-canned queries/reports  197 .  
       FIG. 4  shows a detailed diagram of the preparation step  171  from  FIG. 2  for the first embodiment of the invention. Configuration  198  in  FIG. 4 , includes: authorized users; source IP addresses; targets (URL, IP address, port); user IDs and passwords; authentication scripts; scripts having to do with changes to user ID or password; session token names; login and logout page; inputting the authorized users and their authentication information (e.g., password, cert, etc.); source IP address; target application system user IDs and passwords; and scripts having to with setting or editing the user id or password.  
       FIG. 4  also includes a decision option  199  and two sets of configuration options depending on whether the tester is using the intermediary proxy  7  from  FIG. 1 , as the test proxy or rather an additional proxy (e.g., form scalpel). If an additional proxy is being used  200 , then the application client (browser) is configured to proxy through this additional proxy.  
      In both branches of the former decision, an additional decision regarding the mode of operation for the intermediary proxy  7  in  FIG. 1  is made and this represented by  200  and  201 . The intermediary proxy mode of operation can either be as a reverse proxy or forward (or caching) proxy.  
      In the reverse proxy mode, the intermediary proxy appears as the origin server and the tester uses the intermediary proxy as the origin server (i.e., all requests will have a URL that resolves to the intermediary proxy  7  of  FIG. 1 ). Configuration options for this mode of operation are represented in  203  of  FIG. 4 , which outlines the configuration necessary for the tester and the intermediary proxy  7  of  FIG. 1 .  
      In the forward proxy mode of operation, the tester configures the application client (browser or internal proxy) to proxy through the intermediary proxy  7  of  FIG. 1 . These configuration settings are outlined in  204  and  205  of  FIG. 4 .  
       FIGS. 5   a - 5   c  illustrate a detailed flow chart for the first embodiment of the invention. In step  218 , An HTTP request is directed and relayed through the intermediary proxy  7 . The request can also be relayed to the origin server.  
       FIG. 6  shows an example top level display  250  for one embodiment of the graphical display  6  of  FIG. 1 , for one embodiment, providing the auditor with a visual indication of the tests  251 ,  252 ,  253 ,  254  being conducted, color coding may be used to indicate various meanings (e.g., red (problem), yellow (warning—may need attention), green (no known problems) status. The auditor could then select one of the tests being audited and drill down to observe more in depth information, generate statistics or metrics, etc.  
       FIG. 7  shows a sample lower level display for one embodiment of the graphical display  6  in  FIG. 1  that allows the user to select among a number of different test categories: SQL injection attempts  255 , overflow attempts  256 , forced browsing  257 , and cross-site scripting attempts  258 .  FIG. 7  also depicts an alerts  259  tab as an example graphical component of an embodiment. The auditor(s)  39  could drill down and obtain all counts for all alerts and their corresponding threshold setting.  FIG. 7  also shows various other tabs, each of which can be selected or drilled down into, including: real time  260 , allowing the user to move to a display area that shows real time activity and related tabs; past transactions  261 , allowing the user to move to a display area with various information and selectable options for viewing information related to past data and transactions; a configure  262  tab to select a display area that allows the user to select various configurable options; parameters/attributes/cookies  263  tab that has built-in or creatable queries that display data in various ways; metrics  264  which display all the metrics associated with the effort being viewed; a default graph  265  and tab that displays a user selectable default graph and drill down into other selectable graphs; and a list of detected tools  266 .  
       FIG. 8  shows an example display of either a current HTTP transaction or HTTP transaction selected from the database  12  of  FIG. 1 , as well as a sample rendered page  273 . Both the HTTP Request  274  and HTTP Response  275  are illustrated.  
       FIG. 9  illustrates an example display for an embodiment of the invention with a list of HTTPS requests  267  in the top pane. These HTTPS transactions may be any grouping of transactions, including real-time requests (i.e., the stream of requests being made at the present time), requests made for a particular session, requests associated with a particular user ID, requests containing a particular variable or variable value, requests containing a particular cookie and value, etc. Within the list of HTTPS Requests  267 , one particular request  268  is illustrated. The pane directly below the HTTPS request pane  271 , is the header window. This header window  271  pane is used to display an HTTPS Request or HTTPS Response Header. The user can toggle between the HTTPS Request and the corresponding HTTPS Response by selecting the request tab  269  or the response tab  270  respectively. As depicted, for the selected request  268 , and selected request tab  269 , the corresponding raw request header data is displayed within the header window display  267 . In the pane below the header window  267 , is the body window  271 , where the body of either the HTTPS Request or corresponding HTTPS Response is displayed. For the particular request  268  selected in the List of HTTPS Requests, the request did not have any POST data and therefore there is no data within the body. If the Response Tab were selected by the user, the Response Header for the Response corresponding to the selected particular Request  268  would be shown in the Header Window  267  and the Body Window  273  would contain data for that response.  
       FIG. 10  shows a logical diagram of the functional components for another embodiment of the invention.  FIG. 10  illustrates the general relationship between the functional components and their general interaction and is also illustrates the physical relationship between the components. Data communicated between the testing entity  78  for application client  3  and the application system  110  in  FIG. 10  is represented by the communication link  108 . The sniffer  300  is installed such that sniffer  300  has access to the data  108  flowing on communication link  216  between the application client  3  and the application system  110  via connection  109 , and has the necessary certs and keys to decrypt this data  108  where necessary. Sniffer  300 , although shown together with various other functional elements of the invention, may or may not be collocated with other functional elements of the invention.  
       FIG. 11  shows a detailed diagram of the preparation step  171  from  FIG. 3   a  for the embodiment of  FIG. 10  of the invention. Configuration  207  in  FIG. 11  includes: authorized users; source IP addresses; targets (URL, IP address, port); user IDs and passwords; authentication scripts; scripts having to do with changes to user id or password; session token names; login and logout page; inputting the authorized users and their authentication information (e.g. password, cert, etc.); source ip address; target application system user ids and passwords; and scripts having to with setting or editing the user id or password.  
      Step  208  of  FIG. 11  shows the acquisition of application system and application client user certificates and associated keys necessary to decrypt the sniffed traffic. The sniffer  300  of  FIG. 10  must be installed at a point logically between the application system and application client, with access to all data being communicated between the application client  3  and application system  27 , as per step  209  of  FIG. 11 .  
      Thus, when a passive sniffer/extractor  300  is logically placed somewhere between the testing entity and the application system, the passive sniffer/extractor  300  has access to all data flowing between the testing entity and the application system. Examples include: connecting the sniffer/extractor to a hub being used by the testing entity; a software shim installed on a reverse proxy or web server; a software module installed on a standard proxy; a sniffer/extractor appliance connected to a hub that the standard proxy is connected to; and any tap into any of the communication links between the testing entity and the application system.  
      Web applications systems targeted for testing usually utilize SSL, which provides authentication, confidentiality, and data integrity capabilities. The intermediary proxy and sniffer/extractor may implement necessary functionality to unencode/encode, decipher/encipher, unencrypt/encrypt the communication flowing between the testing entity and the application system. Under one configuration, if SSL is being utilized, the intermediary proxy will act as an SSL endpoint. In another configuration, two SSL connections may be created: one between the testing entity and the intermediary proxy; and one between the intermediary proxy and the application system. Since proxying is one of the base techniques used by testing entities to attack/test web applications, it is may sometimes be necessary for an additional connection to be created: one between the testing entity browser/client and the testing entity proxy. As a result, the testing-entity-to-intermediary proxy connection will be from the testing entity&#39;s proxy to the intermediary proxy.  
      For the intermediary proxy implementation, when SSL is being used, the intermediary proxy will act as an SSL endpoint comprising a server certificate, and if necessary appropriate client certificates. Thus, the testing entity will connect to the intermediary proxy and will see the intermediary proxy as the origin server and be served an SSL certificate from the intermediary proxy rather than the application system. Accordingly, the intermediary proxy will include the necessary functionality to execute the vulnerability/penetration tests related to SSL certificates against the origin server. Also, when SSL is being used with an intermediary passive sniffer/extractor, keys and necessary logic to decipher the data being communicated between the testing entity and the application system to be supplied with the server, and if necessary the client.  
       FIG. 12  shows a logical diagram of the functional components for another embodiment of the invention.  FIG. 12  illustrates the general relationship between the functional components and their general interaction and also illustrates the physical relationship between the components. Data is communicated between the application client  115  and the application system  154  in  FIG. 12  by a communication means represented by the communication link  170 .  
      A data collector software module  116  is installed in the testers platform (browser of proxy) and/or a data collection software module  157  is installed in the application system (reverse proxy  159 , web server  158 ). The data collectors  116 ,  157  collect the data being communicated between the application client  3  and application system  27  as well as actions being undertaken by the tester. The data collector has capabilities to store the data locally and/or securely transmit the data to the process functional elements of the invention. The data collectors  116 ,  157  also have remote connectivity functionality and displays to allow auditors to shadow the test.  
       FIG. 13  shows a detailed diagram of the preparation step  171  from  FIG. 3   a  for the embodiment of the invention  FIG. 12 . Configuration  210  in  FIG. 13  includes: authorized users; source ip addresses; targets (url, IP address, port); user ids and passwords; authentication scripts; scripts having to do with changes to user id or password; session token names; login and logout page; inputting the authorized users and their authentication information (e.g. password, cert, etc.); source ip address; target application system user ids and passwords; and scripts having to with setting or editing the user id or password,  
      Installation of the data collectors and the available options is outlined in  211  through  215  of  FIG. 13 , whereby the software is installed in the tester&#39;s environment, or in the application system environment. This can include monitoring of the tester&#39;s browser,  212 , and the testers proxy  213 . Alternatively, for installation of a data collector in the application system the data collection module is associated with the application system web server  214  and the application system reverse proxy  215 .  
      Data collecting modules or agents installed on the test entity or application system refers to computing modules that can be plugged into the testing entity and/or application system and which can record all data associated with the testing effort including data flowing between the testing entity and the application system and actions being taken by the testing entity. The use of data collecting modules installed on the testing entity and/or application system will simplify the capture of testing actions allowing for the capture of both un-altered as well altered Requests and the associated Responses.  
      Access to the clear-text vulnerability/penetration test data will be leveraged to capture and permanently store all data flowing between the testing entity and the application, as well as actions being taken by the testing entity, including for example: Connection data; Connection Handshaking data; SSL Handshaking Data (e.g. allowed ciphers); Sockets; Protocol Parameters, for example, HTTP Version(s); HTTP URL(s); HTTP Messages; Start Line(s); Message Header(s); Message Body(s); Request(s); Request-Line(s); Request-URI(s); General-Header Field(s) and Value(s); Request-header Field(s) and value(s); Entity-header Field(s) and Value(s); Request Message body(s); Response(s); Status-Line(s) (including Status Code and Reason); General-Header Field(s) and Value(s); Response-header Field(s) and value(s); Entity-header Field(s) and Value(s); and Response Message body(s).  
      For intermediary data access engine implementations (i.e. intermediary proxy and/or intermediary sniffer), storage may be local and/or securely and reliably transmitted to a central storage/processing engine. Data access engine agents installed on the test entity and/or the application system will have the capability to securely and reliably store all data locally and/or securely and reliably relay all data back to a central storage and processing engine for secure and reliable storage.  
      In the analyzer, logic applied to the data accessed, collected, parsed and stored, towards yielding information about the data itself, the application system, the testing effort, state-of-the-art, vendor capabilities, trends, and statistics, will include for example: 
      determining actions being taken by the testing entity (e.g. parameter value manipulation);     determining whether and when scanners are being used;     determining the rate of testing (requests per unit of time);     creation of a mapping between the User ID and the session credential set upon successful authentication;     coupling of the User IDs to all requests generated while the testing entity is authenticated as the particular User ID;     identification of hidden form fields and the initial value set within the response;     determination of hidden form fields value changes, affected through manipulation by the testing entity, and the resultant effect or Response;     determination of the particular request(s) that result in the session id being created;    

      When a set of determined User ID/password pairs, as well as the determined script/page where the User ID and password are submitted for authentication, the data will be leveraged by the automation engine to generate valid session ids on the fly, as necessary (e.g. replay or other test against a particular script/page for which a particular user id has authorization for use in testing, retesting, and replay efforts (e.g. CSS, sql injection, parameter manipulation).  
      Access to and/or storage of the clear-text data will allow the data to be parsed, and used in the building of database(s) of information for the testing effort, including the following examples:

      A superset database of vulnerable material will be built and continuously updated with data captured from vulnerability tests being conducted through this method, including: 
          Vulnerable scripts/pages for all tests conducted through this method (e.g. vulnerability scanning engines—NIKTO, ISS, NESSUS, STEALTH, WHISKER, TYPHON, etc.);     CSS strings submitted during the tests run through this method;     All SQL injection strings for all tests submitted through this method;     List of application system components (web server, application server, proxy server) for each application system;     List of components susceptible to CSS, SQL injection, and CR/LF injection;     Realtime Monitoring and Viewing        

      Displays, interpreters, code/logic and access to the data being communicated between the test entity and the application system, as well as derived data, will allow authorized interested parties to view, in real-time as well as replay, all aspects of the testing activity, related generated information, including a display of all examples listed in previous claims, as well as the following examples: 
          Raw HTTP Requests and Responses;     Rendered/interpreted Responses;     Parameter manipulation;     Lack of testing activity;     Signals indicating activity or lack of activity;     Signals indicating the use of a scanning utility;     List of URLs requested;     Any of the data cited in claims  37  and  40 ;     Findings detected by method;     Data/Information Reporting        

      Access to the data being communicated between the test entity and application system, as well as derived data, will allow for the generation of reports to include for example, all data listed above. Thus, authorized interested parties can make ad-hoc and pre-canned queries against the stored data for either a test currently in progress, or a past test; and can retrieve and/or view reports containing various information indicating the completeness and efficacy of the test(s), including the following examples: 
          Statistics;     Comparison data;     Directories;     Scripts/pages Requested;     Accounts and passwords used;     Parameters and values;     Access Control:Authorized Interested Party        

      Thus, access control protects and governs access to all functionality and data, including: 
          which source IP addresses can make connections through an intermediary proxy data access engine and to which application systems;     which source IP addresses and accounts can make connections to agent data access engine;     which source IP addresses and accounts can access the functionality provided by the method;     which source IP addresses and accounts can access the data and reports provided by the method; and     which interested parties can make connections for monitoring, database queries, reporting, scanning, scoring, etc.        

      The agents will also include the necessary logic for an authorized interested party to securely connect to the data collecting modules. In combination, or separately, this will allow interested parties the same view into testing activity as the intermediary and sniffer implementations.  
      A testing engine platform may be included that implements all the necessary functionality to communicate with the application system, and which can be used to: 
          replay stored requests with or without modification by an authorized, authenticated, interested party that can be leveraged by authorized testing entities and other authorized interested parties;     to run automated scans using the superset vulnerability database described above, and     used as the proxy through which the testing entity can conduct tests.
