The TOE is installed in a general office and used in an environment connected to the PSTN and a LAN which is the internal network of the organization. Users operate the control panel of the TOE or a client PC (i.e. General User Client or System Administrator Client) connected to the LAN to use the TOE. JISEC-CC-CRP-C0777-01-2023 9 Figure 4-1 Operational Environment of the TOE The operational environment of the TOE consists of the following components. 1) General User Client A general user client is a general-purpose PC for general users. The following software is required: - OS: Windows 10 - Web browser: Microsoft Edge - Printer driver (Provided by Xerox Corporation) PCL6 5.887.3.0 2) System Administrator Client A system administrator client is a general-purpose PC for system administrators. The following software is required: - OS: Windows 10 JISEC-CC-CRP-C0777-01-2023 10 - Web browser: Microsoft Edge 3) Mail Server A mail server is used to send user document data from the TOE. Software supporting the SMTP protocol with TLS 1.2 is required. The following software was used in this evaluation: - OS: Cent OS 7.6 - Mail Server: Postfix version 2.10.1 4) Audit Server An audit server is a server to store audit logs generated by the TOE. The following software is required: - OS: Windows 10 - PowerShell script to retrieve audit logs from the TOE (described in the TOE guidance) - PowerShell Version 5.1 (OS built-in tool) It should be noted that the reliability of the hardware and the software other than the TOE shown in this configuration is outside the scope of this evaluation. Those are assumed to be trustworthy. JISEC-CC-CRP-C0777-01-2023 11 4.3 Clarification of Scope There are the following restrictions on the security functions provided by the TOE or ensured by this evaluation. 1) Servers and client PCs System administrators are responsible for operating servers and client PCs cooperating with the TOE securely. 2) Audit server operation An audit server polls the TOE periodically to read out audit logs stored on the TOE. The TOE sends all the stored audit logs on the polling, regardless of whether they have already been read out. System administrators are responsible for distinguishing newly generated audit logs from duplicated data and extracting necessary audit logs. 3) Overwrite residual image data function The function that overwrites and deletes the image data stored in the TOE's internal storage (eMMC) is not ensured by this evaluation. JISEC-CC-CRP-C0777-01-2023 12 5. Architectural Information This chapter explains the scope and the main components of the TOE. 5.1 TOE Boundary and Components The TOE is the entire MFD with the necessary option. The functions provided by the TOE consist of the basic functions of the MFD and the security functions. Regarding the basic functions of the MFD such as copy, scan, print, and fax, please refer to Chapter 11. The security functions of the TOE are described below. 1) Identification and Authentication This function is to identify and authenticate users of the TOE with their IDs and passwords. This function is applied when the TOE is used as follows: - When users use the TOE with the control panel of MFD, or Web browser on client PC, or printer driver on client PC. (Only the identification of a user ID is performed when using printer driver on client PC.) - When an audit server retrieves the audit logs from the TOE. (The ID and password of System Administrator is used.) This function has the following functionality to strengthen the identification and authentication. - Restriction on the minimum password length. - Suspending the identification and authentication on continuous unsuccessful authentication attempts. - Termination of the session if there is no operation for a certain time after the successful authentication. 2) Access Control This function is to control the access to the user data when users operate the basic functions of the MFD on them. The access control is based on the owner information of the user data and on the user's identification information and role. 3) Data Encryption This function is to encrypt the data stored in the TOE and the communication data. The encryption of the stored data uses AES CBC mode with a 256-bit key. The encryption of communication data is used in the encryption communication protocol described in "4) Trusted Communication. " Encryption keys are generated using a random bit generator with enough entropy that is difficult to guess. 4) Trusted Communication This function is to protect communication data between the TOE and IT devices using JISEC-CC-CRP-C0777-01-2023 13 encryption communication protocol, TLS 1.2. 5) Security Management This function is to restrict the setting, etc. of the security functions to system administrators. For general users, it permits them to change their own passwords. 6) Security Audit This function is to generate audit logs on audit events relevant to the security functions and enable an audit server and system administrators to retrieve them. Generated audit logs are stored in the TOE. When the stored logs exceed the storage capacity, the oldest one is deleted to store a new audit log. 7) Trusted Operation This function consists of the following functionality: - Verification of the check sum of the firmware and the correct operation of the random bit generation at start-up of the TOE. - Verification of the digital signature of new firmware when the firmware is updated. 8) PSTN Fax-Network Separation This function is to separate the Public Switched Telephone Network (PSTN) and the LAN. It prevents sending and receiving data from the PSTN to the LAN via the TOE. 5.2 IT Environment The TOE communicates with servers and client PCs via LAN. The function of the TOE described in "4) Trusted Communication" works in cooperation with those IT devices and uses the following protocols: - Client PC (Web browser): HTTP over TLS - Client PC (Printer driver): IPP over TLS - Audit Server: HTTP over TLS - Mail Server: SMTP over TLS JISEC-CC-CRP-C0777-01-2023 14 6.

It is periodically confirmed that the above Evaluation Facility meets the requirements on the appropriateness of the management and evaluators for maintaining the quality of evaluation. 7.2 Evaluation Approach The evaluation was conducted in accordance with the assurance requirements in the CC Part 3 required by the Conformance PP using the evaluation methods prescribed in the CEM and the assurance activities of the Conformance PP. Details for evaluation activities were reported in the Evaluation Technical Report. The Evaluation Technical Report explains the summary of the TOE as well as the content of the evaluation and the verdict for each work unit in the CEM and assurance activity of the Conformance PP. 7.3 Overview of Evaluation Activity The history of the evaluation conducted is described in the Evaluation Technical Report as follows. The evaluation started in 2022-07 and concluded upon completion of the Evaluation Technical Report dated 2023-01. The Evaluation Facility received a full set of evaluation deliverables necessary for evaluation provided by the developer, and examined the evidence in relation to a series of evaluation conducted. Furthermore, the evaluator conducted the evaluator testing at the developer site in 2022-08 and 2022-09. Concerns found in evaluation activities were issued as the Observation Reports and reported to the developer. Those concerns were reviewed by the developer, and all the concerns were solved eventually. Concerns in the evaluation process that the Certification Body found were described as the certification oversight reviews and sent to the Evaluation Facility. After the Evaluation Facility and the developer examined the concerns, those were reflected in the Evaluation Technical Report. JISEC-CC-CRP-C0777-01-2023 16 7.4 IT Product Testing As the verification results of the evidence shown in the evaluation process, the evaluator performed the evaluator independent testing to ensure that the security functions of the product are accurately implemented, and the evaluator penetration testing based on vulnerability assessments. 7.4.1 Developer Testing The developer testing is not included in the assurance requirements of this evaluation. 7.4.2 Evaluator Independent Testing The evaluator performed the evaluator independent testing (hereinafter referred to as the "independent testing") based on the evidence shown in the evaluation process to ensure that the security functions of the product are accurately implemented. The independent testing performed by the evaluator is explained below. 1) Independent Testing Environment The environment for the independent testing is based on the operational environment of the TOE shown in Figure 4-1. The components used in the independent testing environment are shown in Table 7-1. Table 7-1 Components for the Independent Testing Components Description TOE Xerox VersaLink B405DN Version: Controller ROM Ver. 1.90.3 Client PC (General User Client) - OS: Microsoft Windows 10, Microsoft Windows 10 Professional - Web browser: Microsoft Edge - Printer Driver: PCL6 5.887.3.0 Client PC (System Administrator Client) - OS: Microsoft Windows 10, Microsoft Windows 10 Professional - Web browser: Microsoft Edge Mail Server - OS: Cent OS ver7.6 - Postfix version 2.10.1 Audit Server - OS: Microsoft Windows 10, Microsoft Windows 10 Professional - PowerShell Version 5.1 - PowerShell Script (described in the guidance) The TOE tested by the evaluator has the same identification as the TOE identification in Chapter 2. The configuration of the independent testing except the TOE is different from the TOE configuration identified in the ST in the points described below. The evaluator determined that there are no problems with the differences and that the security functions of the TOE configuration identified in the ST can be considered properly tested. JISEC-CC-CRP-C0777-01-2023 17 (1) Using a modified firmware for testing In the independent testing, a firmware modified for testing was used to verify the encryption functions instead of the firmware of the TOE. The evaluator determined that the testing on the modified firmware is valid because its modules of the encryption functions are the same as that of the TOE, and the modification for testing does not affect the encryption functions. (2) Using additional tools for testing In the independent testing, some tools for testing were used to confirm and alter the communication data. Those tools for testing were validated by the evaluator. 2) Summary of the Independent Testing A summary of the independent testing performed by the evaluator is described below. a. Viewpoints of the Independent Testing Viewpoints of the independent testing devised by the evaluator based on the requirements of the Conformance PP and on the provided evaluation documentation are as follows. (1) Confirm security functions for each Security Functional Requirement (SFR). (2) Confirm if the implementation of the cryptographic algorithms is correct. b. Independent Testing Outline An outline of the independent testing performed by the evaluator is as follows. The behavior of the TOE on inputs using the control panel of the TOE, the client PC, the audit server and the testing tools was confirmed by following means: - If the behavior can be confirmed from the external interfaces of the TOE, the external interfaces of the TOE are used. - If the behavior cannot be confirmed from the external interfaces of the TOE, the developer interface of the TOE and the firmware for testing are used. The evaluator performed the independent testing of 19 items. Table 7-2 shows contents of the independent testing corresponding to the viewpoints. JISEC-CC-CRP-C0777-01-2023 18 Table 7-2 Performed Independent Testing Viewpoint Outline of the Independent Testing (1) Confirm that all security functions work as the specification with the test items created based on the assurance activities of the Conformance PP for each SFR or the requirements of the SFR.

The Certification Body confirmed such concerns pointed out in the certification oversight reviews were solved in the ST and the Evaluation Technical Report and issued this Certification Report. 8.1 Certification Result As a result of verification of the Evaluation Technical Report, Observation Report and related evaluation documentation submitted by the Evaluation Facility, the Certification Body determined that the TOE evaluation satisfies the assurance requirements required by the Conformance PP. 8.2 Recommendations Procurement entities who are interested in the TOE are advised to refer "4.2 Environmental Assumptions" and "7.5 Evaluated Configuration" to make sure the scope of the evaluation and the operational requirements of the TOE meet the operational conditions assumed by each user. It is necessary that an audit server polls the TOE periodically to read out audit logs from the TOE. The system administrator for the TOE needs to determine the interval time of polling based on the consideration of your operational policy for audit logs and your usage of the TOE. Note that if the polling interval is too short, the audit server might run short of storage area because the TOE sends all stored audit logs every polling. Also note that if the polling interval is too long, audit logs might be lost. JISEC-CC-CRP-C0777-01-2023 24 9. Annexes There is no annex. 10.
