Installation Guide 6.1.2 Supplement. 11 Evaluation Analysis Activities The evaluation analysis activities involved a structured evaluation of the Network Chemistry RFprotect™ Distributed v6.1.2, RFprotect™ Sensor v6.1.22, and RFprotect™ Mobile v6.1.2, including the following areas: Configuration management: An analysis of the RFprotect™ CM system and associated documentation was performed. The evaluators found that the RFprotect™ configuration items were clearly marked, and could be modified and controlled. The developer’s configuration management system was observed during a site visit, and it was found to be mature and well developed. Secure delivery and operation: The evaluators examined the delivery documentation and determined that it described all of the procedures required to maintain the integrity of the RFprotect™ during distribution to the consumer. The evaluators examined and tested the installation, generation and start-up procedures, and determined that they were complete and sufficiently detailed to result in a secure configuration. Design documentation: The evaluators analysed the RFprotect™ functional specification and high-level design; they determined that the documents were internally consistent, and completely and accurately instantiated all interfaces and security functions. The evaluators also independently verified that the correspondence mappings between the design documents were correct. Guidance documents: The evaluators examined the RFprotect™ user and administrator guidance documentation and determined that it sufficiently and unambiguously described how to securely use and administer the product, and that it was consistent with the other documents supplied for evaluation. Vulnerability assessment: The RFprotect™ ST’s strength of function claims were validated through independent evaluator analysis. The evaluators also validated the developer’s vulnerability analysis and found that it sufficiently described each of the potential vulnerabilities along with a sound rationale as to why it was not exploitable in the intended environment. Additionally, the evaluators conducted an independent review of public domain vulnerability databases, and all evaluation deliverables to provide assurance that the developer has considered all potential vulnerabilities. All these evaluation activities resulted in PASS verdicts. 12 ITS Product Testing Testing at EAL2 consists of the following three steps: assessing developer tests, performing independent functional tests, and performing independent penetration tests. CCS Certification Report Network Chemistry Inc. RFprotect™ ___________________________________________________________________________ Version 1.0 15 May 2007 - Page 9 of 12 - 12.1 Assessment of Developer Tests The evaluators verified that the developer had met their testing responsibilities by reviewing the developer’s test plan, test approach, test procedure and test results, and examining their test evidence, as documented in the Evaluation Technical Report (ETR)2 . The evaluators analyzed the developer’s test coverage analysis, and found that the correspondence between tests identified in the developer’s test documentation and the functional specification was complete and accurate. 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. These tests focused on: • Identification and authentication; • Audit; • Security Management; • Basic product functionality. 12.3 Independent Penetration Testing Subsequent to the examination of the developer's vulnerability analysis and the independent review of public domain vulnerability databases and all evaluation deliverables, limited independent evaluator penetration testing was conducted. The penetration tests focused on: • Generic vulnerabilities; • Bypassing; • Tampering; and • Direct attacks. The evaluator conducted a port scan of the RFprotect™. The only ports found to be open were ones that would be expected. The evaluator used a publicly available tool to scan the 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. CCS Certification Report Network Chemistry Inc. RFprotect™ ___________________________________________________________________________ Version 1.0 15 May 2007 - Page 10 of 12 - RFprotect™ for weaknesses, and none were found. The evaluator also used a publicly available packet capture tool to examine output from the RFprotect™ during startup, shutdown and normal operations. The evaluator searched the captured results in an attempt to extract information which might be useful to a potential attacker; no useful information was uncovered. In addition, the evaluator performed direct attacks on the RFprotect™, attempting to bypass or break the TOE’s database mechanism. The independent penetration testing did not uncover any exploitable vulnerabilities in the anticipated operating environment. 12.4 Conduct of Testing The RFprotect™ was subjected to a comprehensive suite of formally documented, independent functional and penetration tests. The testing took place at the ITSET Facility at EWA-Canada located in Ottawa, Ontario. 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 the ETR. 12.5 Testing Results The developer’s tests and the independent functional tests yielded the expected results, giving assurance that the RFprotect™ behaves as specified in its ST and functional specification. The penetration testing resulted in a PASS verdict, as the evaluators were unable to exploit any of the identified potential vulnerabilities in the RFprotect™ in its intended operating environment. 13 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. 14 Evaluator Comments, Observations and Recommendations The complete documentation for the RFprotect™ includes a comprehensive Installation and Users Guide. The RFprotect™ is straightforward to configure, use and integrate into a corporate network. Network Chemistry Inc. Configuration Management (CM) and Quality Assurance (QA) provide the requisite controls for managing all CM/QA activities. 15 Glossary This section expands any acronyms, abbreviations and initializations used in this report.
