OVERVIEW
The Canadian Common Criteria Scheme 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 Certification Body, which is managed by
the Communications Security Establishment.
A CCEF 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
17025:2005, 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 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.
The certification report, certificate of product evaluation and security target are posted to the Certified Products
list (CPL) for the Canadian CC Scheme, and to the Common Criteria portal (the official website of the
International Common Criteria Project).

The TOE is a multi-function device that copies and prints with scan and fax capabilities. The Xerox embedded fax
component provides local analog fax capability over public switched telephone network connections and also
enables LanFax, a feature that allows you to fax a document from your workstation without printing it. Xerox’s
workflow scanning component allows documents to be scanned at the device with the resulting image being
sent via email, transferred to a remote file repository or kept in a private (scan) mailbox or placed on a personal
USB storage device.
CSC Security Testing/Certification Laboratories is the CCEF that conducted the evaluation. This evaluation was
completed on 15 June 2016 and was carried out in accordance with the rules of the Canadian Common Criteria
Scheme.
The scope of the evaluation is defined by the security target, which identifies assumptions made during the
evaluation, the intended environment for 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.
Communications Security Establishment, as the Certification Body, declares that the TOE evaluation meets all

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 TOE 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 TOE
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.
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 of the procedures
required to maintain the integrity of the TOE during distribution to the consumer.
The evaluators reviewed the flaw remediation procedures used by developer for the TOE. 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 TOE.

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 ETR.
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.
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 developers tests;
b. Local User: The objective of this test case is to demonstrate creation of a normal user account by
configuring the security password parameters;
c. Create System Administrator: The objective of this test case is to demonstrate creation of a Privileged
user account by configuring the security password parameters;
d. System Administrator and unprivileged user Login: The objective of this test goal is to demonstrate that
an administrator as well as an unprivileged user must present a valid username and password to
authenticate;
e. Secure Print Job: The objective of this test goal is to demonstrate that only the user that submitted a
secure print job will be able to access the data;
f. Confirm Roles Rules: The objective of this test goal is to demonstrate that unprivileged users cannot
access administrative functions;
g. Audit Verify: The objective of this test goal is to demonstrate that specific records are written to the
audit log;
h. Immediate Image Overwrite: The objective of this test goal is to demonstrate that a submitted job has
been properly overwritten;
UNCLASSIFIED
v1.0 9
i. Audit Log Rollover: The objective of this test goal is to demonstrate that the most recent events are
retained when the number of log entries exceeds the maximum; and
j. SSL Verification: The objective of this test goal is to demonstrate that only certified versions of SSL can
be used to connect to 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.

6.4 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 such as Heartbleed, Shellshock, FREAK, POODLE, and GHOST;
b. Port Scan: The objective of this test goal is to discover open ports on the TOE for further investigation;
c. Session Management: The objective of this test goal is to attempt to perform a session hijack;
d. Verify Input Validation: The objective of this test goal is to demonstrate that the TOE is not vulnerable to
unexpected inputs and SQL injections at the Login Page;
e. Illicit Software Update: The objective of this test goal is to attempt to load a custom software package;
and
f. PostScript Hack: The objective of this test goal is to attempt to access the TOE directories by submitting
malicious PostScript print jobs.
