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. 12.2 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 DOMUS IT Security Laboratory test goals: a. Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the developer's tests. The evaluator repeated a third of the developer’s test to gain assurance of the developer’s overall testing effort. The evaluator chose a subset of tests that exercised all of the TOE’s security related interfaces; b. Security Management: The objective of this test is to confirm the security parameters are able to be securely managed by repeating a subset of the developer’s tests as well as a number of independent tests that exercised the security management interfaces; c. User Data Protection: The objective of these tests is to confirm the TOE's ability to protect user data by performing a number of tests against the Role Based Access Control and Slice Size enforcement functions; d. Audit: The objective of these tests is to ensure that User Access Events Logging requirements have been met by confirming the capture of logs and the presence of event details as specified in the ST; and 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.
