authentication server.
 When entering a password, it displays an asterisk instead of the input
character.
 It stops accepting authentication for 5 minutes if password authentication
has failed consecutively.
 After identification and authentication, the session is terminated if no
operation is performed for the time set by the administrator in the case of
the operation panel, or for 5 minutes in the case of the web browser.
(2) Access control function
It is a function to control access of user data when manipulating user data with the
basic functions of the TOE.
 It controls access to user data based on the policy defined for each type of
user such as owner of user data or user role.
(3) Stored data encryption function
It is a function to encrypt and store user data, etc., in the TOE.
 User data and TSF data are encrypted by AES CBC mode with a 256-bit key
and stored.
 An encryption key for encrypting user data, etc., is created by a random
number generator having sufficient entropy.
(4) Network protection function
It is a function to protect user data on the communication path when using the LAN.
 Encrypted communication by TLS 1.2 is used between the TOE and various
servers such as audit server.
 The encryption key used for encrypted communication is created by a
random number generator having sufficient entropy.
 In the communication between the client PC and the TOE, IPP over TLS
communication is used for the printer driver, and HTTPS communication is
used for the web browser.
(5) Security management function
It is a function to restrict the security management of the TOE to the identified and
authenticated users.
 Registration / deletion of internal authentication users, change of minimum
password length, setting of various servers, overwriting of user data and
TSF data, etc., are provided only to users with the administrator role.
 Inquiries about user login names and authority groups of the users
themselves, and change of passwords are provided to all internal
authentication users.
JISEC-CC-CRP-C0693-01-2020

(6) Audit function
It is a function to log events related to use of the TOE and security.
 In addition to the start and end of the audit, a log of the audit event such as
the end of the job and failure of identification and authentication is
generated as audit data. In the audit data, the event name, date and time of
occurrence, user login name, event result and additional information are
recorded.
 The generated audit data is sent to the audit server by using the syslog
protocol and TLS 1.2.
 The audit data generated by the TOE is encrypted and stored in the TOE
until it is successfully transmitted to the audit server. In the TOE, it is
possible to store 40,000 audit data. The audit data generated newly in excess
of 40,000 is not stored but is discarded.
(7) Software verification function
It is a function that the TOE verifies the update firmware and enables installation
of only legitimate firmware.
 It verifies that it is a legitimate firmware by checking the hash value of the
firmware with a digital signature provided at the same time as the firmware
and the hash value calculated by the TOE using SHA - 256.
 A user with the administrator role can acquire the version of the firmware.
(8) Self-testing function
It is a function to verify the normal operation of the security functions at the start-
up of the TOE.
 Verification that the security functions operate normally is done by the
entropy source health test of the random number generator, by the known
answer test of the encryption algorithm, and by confirming that the
firmware is not corrupted.
 In the verification, if any error is detected in all or in part, the TOE stops the
start-up and suspends any operation until the power is turned off.

7 Evaluation conducted by Evaluation Facility and Results
7.1 Evaluation Facility
Information Technology Security Center Evaluation Department that conducted the
evaluation as the Evaluation Facility is approved under JISEC and is accredited by NITE
(National Institute of Technology and Evaluation), the Accreditation Body, which joins
Mutual Recognition Arrangement of ILAC (International Laboratory Accreditation
Cooperation). 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 on 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 2020-03 and concluded upon completion of the Evaluation
Technical Report dated 2020-11.
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 evaluators conducted the evaluator testing at the developer site in
2020-07.
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.
JISEC-CC-CRP-C0693-01-2020
17
Concerns in the evaluation process that the Certification Body found were described as
the certification oversight reviews, and they were sent to the Evaluation Facility.
The Evaluation Facility and the developer examined them, which was reflected in the
Evaluation Technical Report.
7.4 IT Product Testing
As the verification results of the evidence shown in the evaluation process, the evaluators
performed the independent testing to ensure that the security functions of the product are
accurately implemented and penetration testing based on the vulnerability assessment.
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 evaluators conducted evaluator independent testing (hereinafter referred to as
"independent testing") based on the evidence presented during the evaluation to ensure
that the security functions of the product are accurately implemented.
The independent testing performed by the evaluators is explained as follows.
Independent Testing Environment
Configurations for the independent testing are based on the operational
environment of the TOE shown in Figure 4-1, and the components are as shown in
Table 7-1. Although there are differences in the following points, the evaluator also
evaluates that these configurations are equivalent to the configuration identified in
the ST, and there is no problem in checking the function of this TOE.
- Firewalls installed to protect the TOE against unauthorized access from the
external network do not exist in the testing environment because they do not
affect the operation of the TOE.
- In the TLS test, communication between the TOE and the server / client PC is
performed via the TLS testing tool created by the Evaluation Facility. Since the
TLS testing tool only modifies the packet data of the TLS handshake message,
it does not affect the functions of the TOE.
- For some tests such as cryptographic tests, the testing firmware created by the
developer is used for calling for testing the cryptographic modules in the TOE.
JISEC-CC-CRP-C0693-01-2020
18
The module called in the test using the testing firmware is the same as the
module of the TOE, so it does not affect the functions of the TOE.

7.4.3 Evaluator Penetration Testing
The evaluators devised and performed the necessary evaluator penetration testing
(hereinafter referred to as the "penetration testing") on the potentially exploitable
vulnerabilities of concern under the assumed environment of use and attack level from
the evidence shown in the process of the evaluation.
The penetration testing performed by the evaluators is explained as follows.
Summary of the Penetration Testing
A summary of the penetration testing performed by the evaluators is as follows.
a. Vulnerability of Concern
The evaluators searched into the provided documentation and the publicly available
information for the potential vulnerabilities, and then identified the following
vulnerabilities which require the penetration testing.
1. There is concern that it can be exploited by the fact that the unintended port
of the TOE is enabled or a publicly known vulnerability exists in the running
network service.
2. In the TOE web interface, there is concern that it can be exploited by the
existence of publicly known vulnerabilities, such as bypass of the
identification and authentication function by direct designation of URL, and
XSS.
3. There is concern that buffer overflow or arbitrary code execution may occur
due to unauthorized print data input to the TOE.
4. There is concern that the identification and authentication function may be
bypassed due to unauthorized input from the operation panel, printer driver
and web interface.
5. When the TOE operates as a TLS client, there may be vulnerabilities in the
verification process of the server certificate of the communication destination.
b. Penetration Testing Outline
The evaluators performed the following penetration testing to identify potentially
exploitable vulnerabilities.
