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 Centrify Suite 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 Centrify Suite configuration management system and
associated documentation was performed. The evaluators found that the Centrify Suite
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 Centrify Suite during distribution to the
consumer.
Theevaluatorsreviewed theflaw remediationproceduresused by developer for theCentrify
Suite. Duringasitevisit, theevaluatorsalso examined theevidencegenerated by adherenceto
theprocedures. Theevaluatorsconcluded that theproceduresareadequateto track and correct
security flaws, and distributetheflaw informationand correctionsto consumersof theproduct.
Vulnerability assessment: The evaluators conducted an independent vulnerability analysis of
Centrify Suite. Additionally, the evaluators conducted a search of public domain vulnerability
databases to identify Centrify Suite 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 Centrify Suite.
All these evaluation activities resulted in PASS verdicts.
11 10BITS Product Testing
Testing consists of the following three steps: assessing developer tests, performing
independent functional tests, and performing penetration tests.

11.1 17BAssessment 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 ETRP1F
2
P.
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 18BIndependent 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 show that the TOE can be installed and
configured into its evaluated configuration;
c. Identity Management (Redhat and Mac): The objective of this test goal is to show that the
TOE provides the security functions required to establish a session on a UNIX resource;
d. Authentication failure Handling (Redhat and Mac): The objective of this test goal is to
confirm that the TOE enforces offline authentication failure handling on both Redhat and
Mac; and
e. Inter-TSF Trusted channel: The objective of this test goal is to demonstrate that the TOE
provides a secure channel for the purpose of either reading or writing Active Directory
security objects and attributes.
11.3 19BIndependent 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. Port Scan: The objective of this test goal is to confirm that only the expected ports were
found open on the Windows, Redhat Linux, and Mac operating system;
b. Tool Scanning: The objective of this test goal is to scan for known and unknown
weaknesses relevant to the TOE type; and
c. Escalation of privilege vulnerabilities: The objective of this test goal is for a user to
attempt to escalate their privileges on the TOE.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
11.4 20BConduct of Testing
Centrify Suite was subjected to a comprehensive suite of formally documented, independent
functional and penetration tests. The testing took place at the Information Technology Security
Evaluation and Test (ITSET) Facility at EWA-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 21BTesting Results
The developer’s tests and the independent functional tests yielded the expected results, giving
assurance that Centrify Suite behaves as specified in its ST and functional specification.
12 11BResults 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 12BEvaluator Comments, Observations and Recommendations
Centrify Suite 2013.2 includes a mature, comprehensive set of user documents. Implementers
of the TOE should pay particular attention to the configuration instructions in the Guidance
