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, fax,
and document storage and retrieval 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.
- 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-C0789-01-2023
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.
9) Overwrite Hard Disk
This function is to overwrite the area of the hard disk drive in the TOE where user
document data are stored when those data are deleted by completion of the basic function
of the TOE or by deletion operation by users, etc.
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

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.

There are following differences between the configuration of the independent testing and
the TOE configuration identified in the ST. The evaluator determined that there are no
JISEC-CC-CRP-C0789-01-2023
17
problems with the differences and that the security functions of the TOE configuration
identified in the ST can be considered properly tested.
(1) Tested models
In the models of the TOE described in Chapter 2 "TOE identification," there are multiple
models due to the following differences:
- Number of Fax lines
- Difference in printing speed
The evaluator determined that the security functions of all the models of the TOE can be
considered to have been tested by testing the representative three models considering
the above differences, because the security functions of each model are the same.
(2) 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.
(3) Using additional tools for testing
In the independent testing, some tools for testing were used to confirm and alter the
communication data and to confirm the data written in the hard disk drive. 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.
<Viewpoints of the Independent Testing>
(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.
<Independent Testing Approach>
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.
JISEC-CC-CRP-C0789-01-2023
18
- If the behavior cannot be confirmed from the external interfaces of the TOE, the
developer interface of the TOE, the analyzer for the hard disk drive in the TOE and the
firmware for testing are used.

8. Certification
The Certification Body performed the certification from the following viewpoints based on
the materials submitted by the Evaluation Facility during the evaluation process.
1. Contents pointed out in the Observation Report shall be adequate.
2. Contents pointed out in the Observation Report shall properly be solved.
3. The submitted documentation was sampled, the content was examined, and the related
work units in the CEM and assurance activities of the Conformance PP shall be
evaluated as presented in the Evaluation Technical Report.
4. Rationale of the evaluation verdict by the evaluator presented in the Evaluation
Technical Report shall be adequate.
5. The evaluator's evaluation methodology presented in the Evaluation Technical Report
shall conform to the CEM and the assurance activities of the Conformance PP.
Concerns found in the certification process were prepared as the certification oversight
reviews, and those were sent to the Evaluation Facility. 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.
