UNCLASSIFIED v1.0 7 5 EVALUATION ANALYSIS ACTIVITIES The evaluation analysis activities involved a structured evaluation of the TOE. Documentation and process dealing with Development, Guidance Documents, and Life-Cycle Support were evaluated. 5.1 DEVELOPMENT The evaluators analyzed the TOE 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 (SFRs). The evaluators analyzed the TOE security architectural description and determined that the initialization process is secure, that the security functions are protected against tamper and bypass, and that security domains are maintained. The evaluators also independently verified that the correspondence mappings between the design documents are correct. 5.2 GUIDANCE DOCUMENTS The evaluators examined the TOE 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 are complete and sufficiently detailed to result in a secure configuration. Section 4.1 provides details on the guidance documents. 5.3 LIFE-CYCLE SUPPORT An analysis of the TOE configuration management system and associated documentation was performed. The evaluators found that the TOE configuration items were clearly marked. The evaluators examined the delivery documentation and determined that it described all of the procedures required to maintain the integrity of the TOE during distribution to the consumer. The evaluators reviewed the flaw remediation procedures used by developer for the TOE. During a site visit, the evaluators also examined the evidence generated by adherence to the procedures. The evaluators concluded that the procedures are adequate to track and correct security flaws, and distribute the flaw information and corrections to consumers of the TOE. UNCLASSIFIED v1.0 8 6 TESTING ACTIVITIES Testing consists of the following three steps: assessing developer tests, performing independent functional tests, and performing penetration tests. 6.1 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 ETR. 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. 6.2 CONDUCT OF TESTING The TOE was subjected to a comprehensive suite of formally documented, independent functional and penetration tests. The detailed testing activities, including configurations, procedures, test cases, expected results and observed results are documented in a separate Test Results document. 6.3 INDEPENDENT FUNCTIONAL TESTING During this evaluation, the evaluator developed independent functional tests by examining design and guidance documentation. All testing was planned and documented to a sufficient level of detail to allow repeatability of the testing procedures and results. The following testing activities were performed: a. Repeat of Developer's Tests: The evaluator repeated a subset of the developers tests; b. Local User: The objective of this test case is to demonstrate creation of a normal user account by configuring the security password parameters; c. Create System Administrator: The objective of this test case is to demonstrate creation of a Privileged user account by configuring the security password parameters; d. System Administrator and unprivileged user Login: The objective of this test goal is to demonstrate that an administrator as well as an unprivileged user must present a valid username and password to authenticate; e. Secure Print Job: The objective of this test goal is to demonstrate that only the user that submitted a secure print job will be able to access the data; f. Confirm Roles Rules: The objective of this test goal is to demonstrate that unprivileged users cannot access administrative functions; g. Audit Verify: The objective of this test goal is to demonstrate that specific records are written to the audit log; h. Immediate Image Overwrite: The objective of this test goal is to demonstrate that a submitted job has been properly overwritten; UNCLASSIFIED v1.0 9 i. Audit Log Rollover: The objective of this test goal is to demonstrate that the most recent events are retained when the number of log entries exceeds the maximum; and j. SSL Verification: The objective of this test goal is to demonstrate that only certified versions of SSL can be used to connect to the TOE. 6.3.1 FUNCTIONAL TEST RESULTS The developer’s tests and the independent functional tests yielded the expected results, providing assurance that the TOE behaves as specified in its ST and functional specification. UNCLASSIFIED v1.0 10 6.4 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 to discover potential network, platform and application layer vulnerabilities such as Heartbleed, Shellshock, FREAK, POODLE, and GHOST; b. Port Scan: The objective of this test goal is to discover open ports on the TOE for further investigation; c. Session Management: The objective of this test goal is to attempt to perform a session hijack; d. Verify Input Validation: The objective of this test goal is to demonstrate that the TOE is not vulnerable to unexpected inputs and SQL injections at the Login Page; e. Illicit Software Update: The objective of this test goal is to attempt to load a custom software package; and f. PostScript Hack: The objective of this test goal is to attempt to access the TOE directories by submitting malicious PostScript print jobs. 6.4.1 PENETRATION TEST RESULTS The independent penetration testing did not uncover any exploitable vulnerabilities in the intended operating environment.
