Executive Summary
EMC Isilon® OneFS® v7.2.0.4 from EMC Corporation, is the Target of Evaluation. The
results of this evaluation demonstrate that EMC Isilon® v7.2.0.4 meets the requirements of
Evaluation Assurance Level (EAL) 2 augmented for the evaluated security functionality.
EMC Isilon® OneFS® v7.2.0.4 combines the three layers of storage architecture—file
system, volume manager, and data protection – into a scale-out NAS cluster. Each node adds
resources to the cluster. Because each node contains globally coherent RAM, as a cluster
becomes larger, it becomes faster. Meanwhile, the file system expands dynamically and
redistributes content, which eliminates the work of partitioning disks and creating volumes.
Segmenting and distributing data —a process known as striping—not only protects data, but
also enables a user connecting to any node to take advantage of the entire cluster's
performance.
The TOE uses distributed software to scale data across commodity hardware. Nodes work as
peers to spread data across the cluster. No master device controls the cluster; no slaves
invoke dependencies. Instead, each node helps control data requests, boosts performance, and
expands the cluster's capacity.
EWA-Canada is the CCEF that conducted the evaluation. This evaluation was completed on
14 December 2015 and was carried out in accordance with the rules of the Canadian
Common Criteria Evaluation and Certification Scheme (CCS).
The scope of the evaluation is defined by the security target, which identifies assumptions
made during the evaluation, the intended environment for EMC Isilon® v7.2.0.4, and the
security functional/assurance requirements. Consumers are advised to verify that their
operating environment is consistent with that specified in the security target, and to give due
consideration to the comments, observations and recommendations in this certification
report.
Communications Security Establishment, as the CCS Certification Body, declares that the
EMC Isilon® v7.2.0.4 evaluation meets all the conditions of the Arrangement on the
Recognition of Common Criteria Certificates and that the product will be listed on the CCS
Certified Products list (CPL) and the Common Criteria portal (the official website of the
Common Criteria Project).

1 Identification of Target of Evaluation
The Target of Evaluation (TOE) for this EAL 2+ evaluation is EMC Isilon® OneFS®
v7.2.0.4 from EMC Corporation.
2 TOE Description
EMC Isilon® OneFS® v7.2.0.4 combines the three layers of storage architecture—file
system, volume manager, and data protection – into a scale-out NAS cluster. Each node adds
resources to the cluster. Because each node contains globally coherent RAM, as a cluster
becomes larger, it becomes faster. Meanwhile, the file system expands dynamically and
redistributes content, which eliminates the work of partitioning disks and creating volumes.
Segmenting and distributing data —a process known as striping—not only protects data, but
also enables a user connecting to any node to take advantage of the entire cluster's
performance.
The TOE uses distributed software to scale data across commodity hardware. Nodes work as
peers to spread data across the cluster. No master device controls the cluster; no slaves

9 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of EMC Isilon® OneFS®
v7.2.0.4, including the following areas:
Development: The evaluators analyzed the EMC Isilon® OneFS® v7.2.0.4 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 EMC Isilon® OneFS® v7.2.0.4 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 EMC Isilon® OneFS® v7.2.0.4
preparative user guidance and operational user guidance and determined that it sufficiently

10 ITS Product Testing
Testing consists of the following three steps: assessing developer tests, performing
independent functional tests, and performing penetration tests.
10.1 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 ETR1
.
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.
10.2 Independent Functional Testing
During this evaluation, the evaluator developed independent functional tests by examining
design and guidance documentation.
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 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. Front panel functionality: The objective of this test goal is to determine what
functionality is available to users of the front panel;
c. Unauthenticated Functionality: The objective of this test goal is to confirm what
functionality is available to unauthenticated users;
d. Auditing: The objective of this test goal is to confirm the auditing capability of the TOE;
and
e. Roles: The objective of this test goal is to confirm the permissions available to each role.
10.3 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. Use of automated vulnerability scanning tools to discover potential network, platform and
application layer vulnerabilities; and
b. OpenSSH MaxAuthTries Exploit: This test attempts to use the OpenSSH MaxAuthTries
exploit that was uncovered during the vulnerability scan.
