OVERVIEW
The Canadian Common Criteria Program provides a third-party evaluation service for determining the trustworthiness of
Information Technology (IT) security products. Evaluations are performed by a commercial Common Criteria Testing
Laboratory (CCTL) under the oversight of the Certification Body, which is managed by the Canadian Centre for Cyber
Security.
A CCTL is a commercial facility that has been approved by the Certification Body to perform Common Criteria evaluations; a
significant requirement for such approval is accreditation to the requirements of ISO/IEC 17025, the General Requirements
for the Competence of Testing and Calibration Laboratories.
By awarding a Common Criteria certificate, the Certification Body asserts that the product complies with the security
requirements specified in the associated security target. A security target is a requirements specification document that
defines the scope of the evaluation activities. The consumer of certified IT products should review the security target, in
addition to this certification report, in order to gain an understanding of any assumptions made during the evaluation, the IT
product's intended environment, the evaluated security functionality, and the testing and analysis conducted by the CCTL.
The certification report, certificate of product evaluation and security target are posted to the Common Criteria portal (the
official website of the International Common Criteria Project).

3 ASSUMPTIONS AND CLARIFICATION OF SCOPE
Consumers of the TOE should consider assumptions about usage and environmental settings as requirements for the
product’s installation and its operating environment. This will ensure the proper and secure operation of the TOE.
3.1 USAGE AND ENVIRONMENTAL ASSUMPTIONS
The following assumptions are made regarding the use and deployment of the TOE:
 The IT environment provides the TOE with the necessary reliable time
 The TOE, the storage nodes, storage clients, switches, storage and management networks, and NTP and LDAP
servers are located within a controlled access facility
 The TOE software will be protected from unauthorized modification
 No malicious software is installed or running on the administrator workstation
 The cluster network is protected from unauthorized access
3.2 CLARIFICATION OF SCOPE
The TOE provides other security features that were not evaluated:
 Encryption At Rest – Encryption is used to encrypt data on SSDs (not enabled by default).
 Integrated Backup and Restore – volumes are backed up to and restored from external object stores.
 Remote Replication – an asynchronous process is used to connect two clusters for continuous data protection.
 Remote Syslog – audit data is forwarded to a remote syslog server.
 Deduplication – multiple copies of data are replaced with references to a shared copy in order to save storage space
and/or bandwidth.
 Quality of Service (QoS) – guaranteed performance is provided by setting minimum, maximum, and burst
parameters for volumes.
 SSH – the SSH protocol used for remote support of a customer’s system.
 SNMP– the SNMP protocol is used to generate SNMP traps, or notifications, associated with audit events (not
enabled by default).
 Multiple VLANs - multi-tenant environment connection to a cluster

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.
The evaluators examined the delivery documentation and determined that it described all the procedures required to
maintain the integrity of the TOE during distribution to the consumer.

6 TESTING ACTIVITIES
Testing consists of the following three steps: assessing developer tests, performing independent tests, and performing a
vulnerability analysis.
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 TESTING
During this evaluation, the evaluator developed independent functional & penetration 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. Degraded Fault Tolerance: The evaluator verified that that the TSF preserves a secure state and ensures the
availability of user data when a node experiences a failure
c. Authentication bypass: The evaluator attempted to bypass user authentication by navigating to URLs supposedly
protected by authentication
d. Multi-level Rollbacks: The evaluator confirmed that rollbacks perform as expected
e. Trusted Path/Secure Administration: The evaluator verified that the TOE is capable of providing a secure
administrative path using HTTPS over the available management interfaces
f. Cryptographic Implementation Verification: The evaluator verified that the claimed cryptographic implementation
was present in the TOE
g. TUI usage: The evaluator verified that the Text User Interface (TUI) performs as required
6.3.1 INDEPENDENT TESTING RESULTS
The developer’s tests and the independent tests yielded the expected results, providing assurance that the TOE behaves as
specified in its ST and functional specification.

6.4 VULNERABILITY ANALYSIS
The vulnerability analysis focused on 4 flaw hypotheses.
 Public Vulnerability based (Type 1)
 Technical community sources (Type 2)
 Evaluation team generated (Type 3)
 Tool Generated (Type 4)
The evaluators conducted an independent review of all evaluation evidence, public domain vulnerability databases and
technical community sources (Type 1 & 2). Additionally, the evaluators used automated vulnerability scanning tools to
discover potential network, platform, and application layer vulnerabilities (Type 4). Based upon this review, the evaluators
formulated flaw hypotheses (Type 3), which they used in their vulnerability analysis.
Type 1 & 2 searches were conducted on 24 December 2021 and included the following search terms:
Element Flash clustered storage system CHAP Intel Xeon E5
SolidFire iSCSI QoSSIOC vulnerabilities Intel Xeon Gold
NetApp JSON-RPC port tcp "8080" vulnerabilities
Netapp element solidfire
OpenSSL
Vulnerability searches were conducted using the following sources:
NetApp Security Advisories
