All these evaluation activities resulted in PASS verdicts. 11 ITS Product Testing Testing at EAL 2 consists of the following three steps: assessing developer tests, performing independent functional tests, and performing penetration tests. 11.1 Assessment of Developer Tests The evaluators verified that the developer has met their testing responsibilities by examining their test evidence, and reviewing their test results, as documented in the ETR2 . The evaluators analyzed the developer’s test coverage analysis and found it to be complete and accurate. The correspondence between the tests identified in the developer’s test documentation and the functional specification was complete. 2 The ETR is a CCS document that contains information proprietary to the developer and/or the evaluator, and is not releasable for public review. CCS Certification Report Websense V10000 G2 7.6 __________________________________________________________________________ Version 1.0 18 January 2012 - Page 7 of 9 - 11.2 Independent Functional Testing During this evaluation, the evaluator developed independent functional tests by examining design and guidance documentation, examining the developer's test documentation, executing a sample of the developer's test cases, and creating test cases that augmented the developer tests. All testing was planned and documented to a sufficient level of detail to allow repeatability of the testing procedures and results. Resulting from this test coverage approach is the following list of CGI IT Security Evaluation & Test Facility test goals: a. Repeat of Developer's Tests: The evaluator repeated all the developer tests to gain a deeper understanding of the TOE and the TOE interfaces. All security functions and interfaces were exercised; b. Security Audit: The objective of this test goal is to determine the TOE’s ability to audit the activity of users; c. Identification and Authentication: The objective of these tests is to ensure that access to the TOE is restricted to authorized administrators only; d. Security Management: The objective of this test goal is to ensure that role based access control requirements have been met and that functionality pertaining to the creation, access, review and approval of administrator defined CCS policies operate as specified; and e. User Data Protection: The objective of this test goal is to determine the TOE's ability to protect user data. 11.3 Independent Penetration Testing Subsequent to the independent review of public domain vulnerability databases and all evaluation deliverables, limited independent evaluator penetration testing was conducted. The penetration tests focused on: a. Use of automated vulnerability scanning tools (NESSUS and NMAP) to discover potential network, platform and application layer vulnerabilities; b. Use of weak passwords to try and gain access to the TOE’s GUI Management tools; c. Use of a third party proxy server in an attempt to bypass defined content restrictions; d. Use of known malicious content files to test the TOE’s capabilities of detecting malicious content that is compressed or obscured; and e. Changing of session cookie to determine if user is able to gain higher privileges. CCS Certification Report Websense V10000 G2 7.6 __________________________________________________________________________ Version 1.0 18 January 2012 - Page 8 of 9 - The independent penetration testing did not uncover any exploitable vulnerabilities in the intended operating environment. 11.4 Conduct of Testing Websense V10000 G2 7.6 was subjected to a comprehensive suite of formally documented, independent functional and penetration tests. The testing took place at the Information Technology Security Evaluation and Test (ITSET) Facility at CGI IT Security Evaluation & Test Facility and at the Websense Quality Assurance Laboratories. The CCS Certification Body witnessed a portion of the independent testing. The detailed testing activities, including configurations, procedures, test cases, expected results and observed results are documented in a separate Test Results document. 11.5 Testing Results The developer’s tests and the independent functional tests yielded the expected results, giving assurance that Websense V10000 G2 7.6 behaves as specified in its ST and functional specification. 12 Results of the Evaluation This evaluation has provided the basis for an EAL 2+ level of assurance. The overall verdict for the evaluation is PASS. These results are supported by evidence in the ETR. 13 Evaluator Comments, Observations and Recommendations The evaluator noted throughout the testing and vulnerability assessment portion of the evaluation that there are a great deal of configuration options available on the Websense V10000 G2 v7.6. As the product is shipped with a default permissive stance, the evaluator strongly recommends professional training for any potential administrator on the product and appliance from a qualified training facility in order to support the ST’s stated assumption that administrators who manage the TOE are not careless, negligent, or willfully hostile and are appropriately trained and will follow all guidance. An unintentional misconfiguration due to a poorly trained administrator can easily lead to security threats not being countered as expected. Additionally it is noted that in order to install the Websense V10000 G2 v7.6, correct placement within the network is important. It is recommended that the administrator consult with their IT architect to ensure proper support for the appliance in the environment as incorrect placement within the network could lead to traffic not being detected on the “N” port for non-http traffic enforcement.
