CCS Certification Report Certes Networks, Inc Certes TNM v3.4 and CEP v2.1.1 ___________________________________________________________________________ Version 1.0 18 December 2012 - Page 8 of 11 - 11 ITS Product Testing Testing at EAL 4 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 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, TOE design and security architecture description 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 is the following list of CGI Security Evaluation and Test Facility test goals: a. Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the developer's tests; b. Trusted Channel: The objective of this test goal is to demonstrate that CEP CLI traffic is protected with SSH; c. Security Management: The objective of this test goal is to demonstrate that user accounts on CEP can be enabled and disabled and verifies that a user cannot log in to the CEP with the disabled account; d. Administrator Roles TMN: The objective of this test goal is to demonstrate the privileges associated with different roles on TMN; and e. Administrator Roles CEP: The objective of this test goal is to demonstrate the privileges associated with different roles on CEP. 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.
