10 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Atmos™ v2.0.1,
including the following areas:
Development: The evaluators analyzed the Atmos™ v2.0.1 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
Atmos™ v2.0.1 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 Atmos™ v2.0.1 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 Atmos™ v2.0.1 configuration management system
and associated documentation was performed. The evaluators found that the Atmos™ v2.0.1
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 Atmos™ v2.0.1 during distribution to the
consumer.
The evaluators reviewed the flaw remediation procedures used by developer for Atmos™
v2.0.1. 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 Atmos™ v2.0.1. Additionally, the evaluators conducted a search of public domain
vulnerability databases to identify Atmos™ v2.0.1 potential vulnerabilities. The evaluators
identified potential vulnerabilities for testing applicable to Atmos™ v2.0.1 in its operational

11 ITS Product Testing
Testing at EAL 2 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 ETR5
.
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 EWA-Canada test goals:
• Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the
developer's tests;
• Password change utility: The objective of this test goal is to verify that an
administrator password is changed on all nodes in a multi-node6
configuration;
• System hardening: The objective of this test goal is to verify that the rPath Linux v2
OS hardening feature is functioning correctly;
• Session timeout: The objective of this test goal is to verify the administrator login
session will time out after the predetermined period of inactivity; and

• Audit collection: The objective of this test case is to verify that audit files are
collected from all distributed nodes by the primary node.
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
with penetration testing focused on password enforcement.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
11.4 Conduct of Testing
Atmos™ v2.0.1 was subjected to a comprehensive suite of formally documented,
independent functional and penetration tests. The testing took place at the developers Quality
Assurance (QA) facility in Cambridge, Massachusetts. 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,
giving assurance that Atmos™ v2.0.1 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 Recommendations
Atmos™ v2.0.1 relies upon an external Simple Mail Transfer Protocol (SMTP) server to
