Operational User Guidance and Preparative Procedures Supplement Concepteers Teleconsole Family Version 2.0, February 7, 2011. 10 Evaluation Analysis Activities The evaluation analysis activities involved a structured evaluation of the Teleconsole Version 2.0, including the following areas: Development: The evaluators analyzed the Teleconsole Version 2.0 functional specification and design documentation; they determined that the design completely and accurately describes the TOE security functionality (TSF) interfaces, the TSF subsystems and how the TSF implements the security functional requirements. The evaluators analyzed the Teleconsole Version 2.0 security architectural description and determined that the initialization process was secure and that the security functions are protected against tamper and bypass. The evaluators also independently verified that the correspondence mappings between the design documents were correct. Guidance Documents: The evaluators examined the Teleconsole Version 2.0 preparative user guidance and operational user guidance and determined that it sufficiently and unambiguously describes how to securely transform the TOE into its evaluated configuration and how to use and administer the product. The evaluators examined and tested the preparative and operational guidance, and determined that they were complete and sufficiently detailed to result in a secure configuration. Life-Cycle Support: An analysis of the Teleconsole Version 2.0 configuration management system and associated documentation was performed. The evaluators found that the Teleconsole Version 2.0 configuration items were clearly marked and that the access control measures as described in the configuration management documentation are effective in preventing unauthorized access to the configuration items. The developer’s configuration management system was also observed during the site visit, and it was found to be mature and well developed. During the site visit the evaluators examined the development security procedures and determined that they detailed sufficient security measures for the development environment to protect the confidentiality and integrity of the Teleconsole Version 2.0 design and implementation. The evaluators confirmed that the developer used a documented model of the TOE life-cycle and that the life-cycle model provides for the necessary control over the development and maintenance of the TOE. The evaluators examined the delivery documentation and determined that it described all of the procedures required to maintain the integrity of Teleconsole Version 2.0 during distribution to the consumer. Vulnerability Assessment: The evaluators conducted an independent vulnerability analysis of Teleconsole Version 2.0. Additionally, the evaluators conducted a review of public domain vulnerability databases, and a search of all evaluation deliverables. The evaluators Version 1.0 18 July 2011 - Page 5 of 9 - CCS Certification Report Concepteers Teleconsole™ Version 2.0 ___________________________________________________________________________ identified potential vulnerabilities for testing applicable to the Teleconsole Version 2.0 in its operational environment. All these evaluation activities resulted in PASS verdicts. 11 ITS Product Testing Testing at EAL 3 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 ETR3 . The evaluators analyzed the developer’s test coverage and depth analysis and found them to be complete and accurate. The correspondence between the tests identified in the developer’s test documentation and the functional specification and TOE design was complete. 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 was the following list of EWA-Canada test goals: a. Initialization: The objective of this test goal is to confirm that the TOE can be installed and configured into the evaluated configuration, as identified in the TOE Description of the Security Target, by following all instructions in the developer’s Installation and Administrative guidance; b. Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the developer's tests on the evaluator’s TOE installation; c. Independent Evaluator Testing: The objective of this test goal is to exercise the TOE’s claimed functionality through evaluator independent testing and to augment any areas that were not covered during the repeat of developer testing; 3 The ETR is a CCS document that contains information proprietary to the developer and/or the evaluator, and is not releasable for public review. Version 1.0 18 July 2011 - Page 6 of 9 - CCS Certification Report Concepteers Teleconsole™ Version 2.0 ___________________________________________________________________________ d. Audit. The objective of this test goal is to exercise the TOE’s claimed audit functionality. Evaluator testing focussed on the backup of TOE audit logs and startup and shutdown of the TOE’s audit functionality; and e. Password Policy. The objective of this test goal is to verify that the TOE enforces administrator configured password policies. 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: • Search for generic vulnerabilities: Vulnerability sites were searched for Teleconsole Version 2.0 vulnerabilities. No vulnerabilities were found; • Bypassing by attempting to exploit the capabilities of TOE interfaces in an unexpected way which could result in a violation of a TOE security policy; • Tampering to verify that the TOE is resistant to standard SQL injection attacks; • Monitoring to verify that the TOE does not leak sensitive information; and • Verification that the TOE continues to operate when a communications failure has occurred. The independent penetration testing did not uncover any exploitable vulnerabilities in the intended operating environment. 11.4 Conduct of Testing Teleconsole Version 2.0 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 Testing (ITSET) Facility at EWA-Canada. 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 Procedures and Test Results document. 11.5 Testing Results The developer’s tests and the independent functional tests yielded the expected results, giving assurance that the Teleconsole Version 2.0 behaves as specified in its ST, functional specification, TOE design, and security architecture description. 12 Results of the Evaluation This evaluation has provided the basis for an EAL 3 level of assurance. The overall verdict for the evaluation is PASS. These results are supported by evidence in the ETR.
