10 Evaluation Analysis Activities

The evaluation analysis activities involved a structured evaluation of VPX3-685, including the following areas:

Development: The evaluators analyzed the VPX3-685 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 VPX3-685 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.

Guidance Documents: The evaluators examined the VPX3-685 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.

Life-cycle support: An analysis of the VPX3-685 configuration management system and associated documentation was performed. The evaluators found that the VPX3-685 configuration items were clearly marked. The developer’s configuration management system was observed during a site visit, and it was found to be mature and well-developed.

The evaluators examined the delivery documentation and determined that it described all of the procedures required to maintain the integrity of VPX3-685 during distribution to the consumer.

The evaluators reviewed the flaw remediation procedures used by developer for the VPX3-685. 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 product.

Vulnerability assessment: The evaluators conducted an independent vulnerability analysis of VPX3-685. Additionally, the evaluators conducted a search of public domain vulnerability databases to identify VPX3-685 potential vulnerabilities. The evaluators identified potential vulnerabilities; subsequent to follow-on penetration testing (ref: section 11.3) it was verified that none of the potential vulnerabilities were exploitable in the operational environment for VPX3-685.

All these evaluation activities resulted in PASS verdicts.

11 ITS Product Testing

Testing 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 ETRFootnote 2.

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.

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:

  1. Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the developer's tests;
  2. VPN functionality: The objective of this test goal is to verify the functionality of the VPN and demonstrate either the correct functionality of the VPN endpoint and show that the TOE logs the appropriate messages when an event occurs;
  3. SSH Testing: The objective of this test goal is to verify the functionality of the Secure Shell (SSH);
  4. Firewall (IPv6): The objective of this test goal is to verify the IPv6 firewall functionality;
  5. Information Flow Control Rules: The objective of this test goal is to verify the flow control rule enforcement of the TOE; and
  6. IDS: The objective of this test goal is to test the IDS functionality of the TOE.

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:

  1. Use of automated vulnerability scanning tools to discover potential network, platform and application layer vulnerabilities;
  2. Attempting to lock out the administrator account by forcing multiple failed SSH logins; and
  3. Attempting to trick the router into routing packets from a trusted network to an untrusted network.

The independent penetration testing did not uncover any exploitable vulnerabilities in the intended operating environment.

11.4 Conduct of Testing

VPX3-685 was subjected to a comprehensive suite of formally documented, independent functional and penetration tests. The testing took place onsite at the developer’s site in Ottawa, 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 Results document.

11.5 Testing Results

The developer’s tests and the independent functional tests yielded the expected results, providing assurance that VPX3-685 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 Recommendation

The TOE is not intended to be deployed as a standalone router in an enterprise. Consumers are expected to be experienced in integrating modular embedded components into larger IT products. The documentation has been written for such an audience.
