10 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of OneFS, including the
following areas:
Development: The evaluators analyzed the OneFS 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 OneFS 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 OneFS 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 OneFS configuration management system and
associated documentation was performed. The evaluators found that the OneFS 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 OneFS during distribution to the
consumer.
The evaluators reviewed the flaw remediation procedures used by EMC Corporation for
OneFS. 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 OneFS. Additionally, the evaluators conducted a search of public domain vulnerability
databases to identify OneFS potential vulnerabilities. The evaluators identified potential
vulnerabilities for testing applicable to OneFS in its operational environment.
All these evaluation activities resulted in PASS verdicts.
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 ETR2
.
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:

a. Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the
developer's tests;
b. Initialization: The objective of this test goal is to provide the procedures for determining
the system configuration in order to ensure that the TOE that is tested is correct;
c. Identification and Authentication: The objective of this test goal is to ensure that the
identification and authentication requirements have been met;
d. Audit: The objective of this test goal is to ensure that the audit data is recorded and can
be viewed;
e. Users and Roles: The objective of this test goal is to ensure the users and roles
functionality is correct;
f. User Data Protection: The objective of this test goal is to determine the TOE's ability to
protect user data; and
g. Basic Product Functionality: The objective of this test goal is to exercise the TOE's
functionality to ensure that the security claims may not be inadvertently compromised.
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:
a. Accessing the TOE via HTTP instead of HTTPS;
b. Access to the Apache.ini file; and
c. Viewing login page source to glean useful information such as password requirements.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
11.4 Conduct of Testing
OneFS was subjected to a comprehensive suite of formally documented, independent
functional and penetration tests. The testing took place at the EMC Quality Assurance
facility located in Seattle, Washington. The detailed testing activities, including
configurations, procedures, test cases, expected results and observed results are documented
in a separate Test Results document.
