Developer Dell EMC
1.1 COMMON CRITERIA CONFORMANCE
The evaluation was conducted using the Common Methodology for Information Technology Security Evaluation, Version 3.1
Revision 5, for conformance to the Common Criteria for Information Technology Security Evaluation, Version 3.1 Revision 5.
The TOE claims the following conformance:
EAL2 + ALC_FLR.2
1.2 TOE DESCRIPTION
The TOE is an all-flash system providing storage for enterprise applications, based on a scale-up and scale-out architecture.
The system uses building blocks, called X-Bricks, which can be clustered together. Each X-Brick contains two storage nodes
in a group of Self Encrypting Devices (SEDs) used in performing Data at Rest Encryption of all data stored on the TOE.
System operation is controlled via a stand-alone dedicated server (using a proprietary hardened Linux OS), called the
XtremIO Management Server (XMS). Each XtremIO cluster requires its own XMS host appliance. The XMS enables control
and management of XtremIO clusters, including:
• Creating, formatting, and initializing new clusters
• Monitoring cluster performance
• Collecting cluster performance statistics
• Providing GUI and CLI services to administrators
• Implementing volume management and data protection groups
• Providing operational support functions
Host Initiators (or Enterprise storage servers) access data on the XtremIO system via the iSCSI protocol. Volumes within
XtremIO are only exposed to initiators that they have been mapped to, and may be further restricted by Virtual Local Area
Networks (VLANs).

5 EVALUATION ANALYSIS ACTIVITIES
The evaluation analysis activities involved a structured evaluation of the TOE. Documentation and process dealing with
Development, Guidance Documents, and Life-Cycle Support were evaluated.
5.1 DEVELOPMENT
The evaluators analyzed the documentation provided by the vendor; they determined that the design completely and
accurately describes the TOE security functionality (TSF) interfaces and how the TSF implements the security functional
requirements. The evaluators determined that the initialization process is secure, that the security functions are protected
against tamper and bypass, and that security domains are maintained.
5.2 GUIDANCE DOCUMENTS
The evaluators examined the TOE 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.
Section 4.1 provides details on the guidance documents.
5.3 LIFE-CYCLE SUPPORT
An analysis of the TOE configuration management system and associated documentation was performed. The evaluators
found that the TOE configuration items were clearly marked.

6 TESTING ACTIVITIES
Testing consists of the following three steps: assessing developer tests, performing independent functional tests, and
performing penetration tests.
6.1 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 Evaluation Test Report (ETR). The correspondence between the tests
identified in the developer’s test documentation and the functional specification was complete.
6.2 CONDUCT OF TESTING
The TOE was subjected to a comprehensive suite of formally documented, independent functional and penetration tests. The
detailed testing activities, including configurations, procedures, test cases, expected results and observed results are
documented in a separate Test Results document.
6.3 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. The following testing activities were performed:
a. Repeat of Developer's Tests: The evaluator repeated a subset of the developer's tests
b. User Role Permissions: For each of user roles that can be created by the administrator, the evaluator verified that
such users were limited to the tasks specified for their assigned role
c. Verification of Cryptographic Implementation: The evaluator verified the presence of the claimed cryptographic
module used by the TOE
6.3.1 FUNCTIONAL TEST RESULTS
The developer’s tests and the independent functional tests yielded the expected results, providing assurance that the TOE
behaves as specified in its ST and functional specification.
