1 Identification of Target of Evaluation
The Target of Evaluation (TOE) for this Evaluation Assurance Level (EAL) 2 augmented
evaluation is EMC VPLEX with GeoSynchrony version 5.0 (hereafter referred to as
VPLEX), from EMC Corporation.
2 TOE Description
VPLEX is a storage network-based federation solution that provides non-disruptive,
heterogeneous data movement and volume management functionality. VPLEX is a software-
only TOE that connects to a Fibre Channel (FC) Storage Area Network (SAN) or Ethernet
switches. The TOE enforces an access control policy on hosts attempting to read from or
write to the storage that the TOE controls. The VPLEX architecture is designed as a high
availability solution.
The TOE consists of only the software portion of VPLEX, which is comprised of the
following:
• The management server software, including the VPLEX command line interface (CLI)
and the management console web-based graphical user interface (GUI). The management
server software is used to issue administrative commands;
• The director software which facilitates Input/Output communication between the front-
end hosts and the back-end storage arrays in a SAN; and
• The VPLEX witness software which provides availability and integrity protection for
data controlled by the TOE.
The Metro deployment configuration (synchronous communications between two or more
clusters) and the Geo deployment configuration (asynchronous communications between two
or more clusters) are the two evaluated configurations.

10 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of VPLEX, including the
following areas:
Development: The evaluators analyzed the VPLEX 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 VPLEX 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 VPLEX 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 VPLEX configuration management system and
associated documentation was performed. The evaluators found that the VPLEX
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 VPLEX during distribution to the
consumer.
The evaluators reviewed the flaw remediation procedures used by the developer for VPLEX.
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 VPLEX. Additionally, the evaluators conducted a search of public domain vulnerability
databases to identify VPLEX potential vulnerabilities. The evaluators identified potential
vulnerabilities for testing applicable to the VPLEX 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 developers have 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 and provide coverage for most of the TOE Security Functions;
b. User Data Protection: The objective of this test goal is to verify that TOE users will be
granted access only to user data for which they have been authorized; and
c. Identification and Authentication: The objective of this test goal is to verify the TOE
password strength policy is being implemented.

___________________________________________________________________________
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. Search of public domain security sites to determine if there are any known or potential
vulnerabilities that could be exploited;
b. Direct Attacks to verify that the TOE web interface does not divulge any proprietary
information and cannot be bypassed to access other resources;
c. Verification that user login credential requirements cannot be bypassed; and
d. Verification that an administrative user of the TOE cannot gain root level access to the
underlying operating system of the TOE.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.
11.4 Conduct of Testing
VPLEX was subjected to a comprehensive suite of formally documented, independent
functional and penetration tests. The testing took place at the developer testing facility
located in Hopkinton, 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 VPLEX 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.
