Foreword

The Canadian Common Criteria Evaluation and Certification Scheme (CCS) provides a third-party evaluation service for determining the trustworthiness of Information Technology (IT) security products. Evaluations are performed by a commercial Common Criteria Evaluation Facility (CCEF) under the oversight of the CCS Certification Body, which is managed by the Communications Security Establishment.

A CCEF is a commercial facility that has been approved by the CCS Certification Body to perform Common Criteria evaluations; a significant requirement for such approval is accreditation to the requirements of ISO/IEC 17025:2005, the General Requirements for the Competence of Testing and Calibration Laboratories. Accreditation is performed under the Program for the Accreditation of Laboratories - Canada (PALCAN), administered by the Standards Council of Canada.

The CCEF that carried out this evaluation is CSC Security Testing/Certification Laboratories.

By awarding a Common Criteria certificate, the CCS 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 CCEF.

This certification report is associated with the certificate of product evaluation dated 10 December 2014, and the security target identified in Section 4 of this report.

9 Evaluation Analysis Activities

The evaluation analysis activities involved a structured evaluation of Xerox MFD, including the following areas:

Development: The evaluators analyzed the Xerox MFD 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 Xerox MFD 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 Xerox MFD 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 Xerox MFD configuration management system and associated documentation was performed. The evaluators found that the Xerox MFD configuration items were clearly marked.

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

The evaluators reviewed the flaw remediation procedures used by developer for the Xerox MFD. 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.

All these evaluation activities resulted in PASS verdicts.

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 ETRFootnote 1.

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:

  1. Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the developer's tests;
  2. Create users and verify Login:
    1. Create normal user account:
    2. Create System Administrator:
    3. User Login:
    4. System Administrator Login:

    The objectives of these test goals are to exercise the ability of an administrator to create accounts and then to test the Login abilities of the accounts;

  3. Software Self-Test: The objective of this test goal is to initiate software verification self-test and confirm that audit log is generated;
  4. Secure Print Access: The objective of this test goal is to demonstrate that only the user that submitted the secure print job will be able to access the data;
  5. IPSec:
    1. IPSec Lan Fax:
    2. IPSec Workflow Scanning

    The objectives of these test goals are to verify confidentiality through encryption over IPSec;

  6. RBAC (Role-based access control):
    1. Administration:
    2. Fax:
    3. Print:
    4. Scan:
    5. Job Deletion:

    The objectives of these test goals are to exercise different access control rules;

  7. Audit download and verify: The objective of this test goal is to download a selection of audit events and verify that they contain proper data; and
  8. Verify Immediate Image Overwrite: The objective of this test goal is to verify if submitted job has been properly overwritten.

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:

  1. Use of automated vulnerability scanning tools to discover potential network, platform and application layer vulnerabilities.
  2. Session Hijack (Cookie): The objective of this test goal is to demonstrate that the TOE is not vulnerable to Session ID attacks;
  3. SQL Injection: The objective of this test goal is to demonstrate that TOE is not vulnerable to SQL injection at the login page;
  4. Login with unexpected input: The objective of this test goal is to demonstrate the TOE rejects invalid data in login fields; and
  5. Malicious PostScript print job: The objective of this test goal is to attempt to access a directory listing using PostScript print jobs.

The independent penetration testing did not uncover any exploitable vulnerabilities in the intended operating environment.

10.4 Conduct of Testing

Xerox MFD was subjected to a comprehensive suite of formally documented, independent functional and penetration tests. The testing took place onsite at the developers location. The CCS Certification Body did not witness any of the independent testing. The detailed testing activities, including configurations, procedures, test cases, expected results and observed results are documented in a separate Test Results document.

10.5 Testing Results

The developer’s tests and the independent functional tests yielded the expected results, providing assurance that Xerox MFD behaves as specified in its ST and functional specification.

11 Results of the Evaluation

This evaluation has provided the basis for a EAL 2+ level of assurance. The overall verdict for the evaluation is

PASS

. These results are supported by evidence in the ETR.
