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, 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 Program).

Lightship Security is the CCTL that conducted the evaluation. This evaluation was completed on 23 September 2024 and
was carried out in accordance with the rules of the Canadian Common Criteria Program.
The scope of the evaluation is defined by the Security Target, which identifies assumptions made during the evaluation, the
intended environment for the TOE, 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.
The Canadian Centre for Cyber Security, as the Certification Body, declares that this evaluation meets all the conditions of
the Arrangement on the Recognition of Common Criteria Certificates, and that the product is listed on the Certified Products
list (CPL) for the Canadian Common Criteria Program and the Common Criteria portal (the official website of the

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. PP Assurance Activities: The evaluator performed the assurance activities listed in the claimed PP; and
b. Cryptographic Implementation Verification: The evaluator verified that the claimed cryptographic implementations
were present and used by the TOE.
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 1 September 2024 and included the following search terms:
Lexmark CX635 Multi-Function Printer v222.037 Lexmark MX532 Multi-Function Printer v222.037
