3. Security Policy
This chapter describes security function policies that the TOE adopts to counter threats,
and organisational security policies.
The TOE provides the Security Functions to counter the unauthorised access to the stored
documents in the MFP, and to protect the communication data on the network.
For meeting the organisational security policies, the TOE provides the functions to
overwrite the internal stored data, to encrypt the stored data in an HDD, and to prevent the
unauthorised access through telephone lines via fax I/F.
For each setting that is relevant to the above mentioned Security Functions, only
administrators are permitted to set configurations in order to prevent the deactivation and
unauthorised use of the Security Functions.

3.1.1.2 Security Function Policies against Threats
All threats shown in Table 3-3 describe breaches (viewing or alteration) of user data and
TSF data caused by persons who are not permitted users for the TOE, or by persons who do
not have any valid authorities.
These threats are countered by the following Security Functions:
JISEC-CC-CRP-C0712-01-2021
13
(1) User identification and authentication
The TOE requires a user to enter the login user name and login password. By
confirming that the entered data are identical to the user authentication data managed
internally by the TOE, the TOE verifies that the person who attempts to use the TOE is
an authorised TOE user. The entry means are the input from Operation Panel of the
TOE itself, the input on a Web browser of client computers, the input via drivers when
using Printer Function and LAN-Fax Transmission.
As a means to ensure the necessary functional strength, the following functions are
provided:
- If users fail to be authenticated consecutively until reaching the specified number
of times set by the MFP administrator, the user accounts are forced to be locked out.
(The user accounts cannot be used until the lockout time elapses or the lockout is
released.)
- The login passwords are required, when they are set, to be composed of more than
the level of quality that has been established in terms of the length (number of
characters) and the character types.
When the login password is validated and a user is confirmed as an authorized TOE
user, the user receives the user privilege that is set in advance in accordance with the
role assigned to the user. Accordingly, the user is allowed to use the TOE. As shown in
"Table 4-2 TOE Users," the roles specified by the TOE include normal user, MFP
administrator, and supervisor.
As a means to support the Identification and Authentication Function, the following
functions are provided:
- Display dummy characters in place of the entered login password on the input
screen.
- After once logged in, if at any time the TOE is not operated by the user or anyone in
a certain period of time, the user account will be automatically logged out.
(2) Access control (Access control against the user data)
For processing request by users, access control to the document information and the
user jobs is performed, based on the login user names and permissions of each user role
of the users. Stored documents are associated with specific information (a document
user list) that stipulates which user is allowed to perform the operation (deletion,
printing, and downloading, etc.). Access control to allow or deny the operation request
by normal user is performed, according to the login user names and the information in
the document user list. The MFP administrator is permitted to delete any stored
documents, but is not permitted to perform any other operation on stored documents.
User jobs are associated with the login user names of the users that create the jobs, and
the normal user who is associated with the login user name is allowed to delete the
applicable job. The MFP administrator is allowed to delete all the user jobs. The
supervisor is forbidden to perform any operations on the user data.
(3) Overwrite residual data
In order to protect from unauthorised access to documents that have been deleted but
remain residually stored in the HDD, temporary documents and their fragments in the
HDD, the residual data shall be overwritten by specified data when deleting the
documents.
JISEC-CC-CRP-C0712-01-2021
14
(4) Network protection
In order to prevent information leakage by being monitored via communication paths,
TLS encrypted communication is used for communications between the TOE and client
computers for the operations via a Web browser and communications using Printer
Function and LAN-Fax Transmission. IPsec communication and S/MIME
communication are also used for the communications between the TOE and the clients.
(5) Security management
In order to protect the TSF data from unauthorised access beyond the user permissions,
access control is performed on actions, such as viewing or altering TOE setting
information, and newly creating or altering user data in accordance with the TOE user
roles. As a permission policy of information alteration (modification), normal users are
only authorised to alter their login passwords, and supervisor is only authorised to alter
the login passwords of the supervisor and the MFP administrators. Only MFP
administrators are allowed to alter the TSF data, except for the above mentioned
permissions.
3.1.2 Organisational Security Policies and Security Function Policies
3.1.2.1 Organisational Security Policies
Organisational security policies required in use of the TOE are shown in Table 3-4. The
evaluation process has confirmed that the security policies except for
P.STORAGE.ENCRYPTION are identical to the security policies in the conformance PP.
P.STORAGE.ENCRYPTION is the security policy that assumes writing data into the HDD
not in a directly readable format.
Table 3-4 Organisational Security Policies
Identifier Organisational Security Policy
P.USER.AUTHORIZATION
(User identification and
authentication)
Only users with operation permission of the TOE shall
be authorised to use the TOE.
P.SOFTWARE.VERIFICATION
(Software verification)
Procedures shall exist to self-verify executable code in
the TSF.
P.AUDIT.LOGGING
(Management of audit log
records)
The TOE shall create and maintain a log of TOE use
and security-relevant events. The audit log shall be
protected from unauthorised disclosure or alteration,
and shall be reviewed by authorised persons.
P.INTERFACE.MANAGEMENT
(Management of external
interfaces)
To prevent unauthorised use of the external interfaces of
the TOE, operations of those interfaces shall be
controlled by the TOE and its IT environment.
P.STORAGE.ENCRYPTION
(Encryption of storage devices)
The data stored on the HDD inside the TOE shall be
encrypted.

3.1.2.2 Security Function Policies to Organisational Security Policies
The TOE provides the security functions to satisfy the organisational security policies
shown in Table 3-4.
(1) Means to support Organisational Security Policy, "P.USER.AUTHORIZATION"
This security policy requires that only officially registered TOE users be allowed to use
the TOE.
The TOE implements this policy by the following Security Function:
(a) User identification and authentication
Based on the user identification and authentication described in Section 3.1.1.2,
whether a person who attempts to use the TOE is an authorised user will be verified
with reference to the identification and authentication information obtained from the
user. A person is provided with the user privileges that are set in advance in
accordance with the role assigned to the user, so that the authorised person is
allowed to use the TOE only if the person is confirmed as an authorised user.
(2) Means to support Organisational Security Policy, "P.SOFTWARE.VERIFICATION"
This security policy requires the validity of the TOE executable code to be self-verified.
The TOE implements this policy by the following Security Function:
(a) Self test
The TOE (configuration items except for FCU) runs a self test during the
initialisation start-up after turning on the power, and it checks the integrity and the
validity of executable codes in the MFP control software and the Operation Panel
control software. The self test verifies the hash values of firmware and confirms the
integrity of the executable code. The test verifies each application on the basis of a
signature key and confirms the validity of the executable code.
If something abnormal is recognised in the MFP control software during the self test,
an error message is displayed on the Operation Panel, and the TOE stops the
operations so that normal users cannot use the TOE. If something abnormal is
recognised in the Operation Panel control software, normal users cannot use the
TOE through the Operation Panel. If no abnormal operations are recognised during
the self test, the TOE continues the start-up processing and makes itself usable for
the users.
As for the FCU, the TOE provides the verification information to perform integrity
verification in a way that the users can confirm it. The users need to confirm the
FCU based on this information, and can use the TOE when there is no problem.
(3) Means to support Organisational Security Policy, "P.AUDIT.LOGGING"
This security policy requires audit logs for the security events of the TOE to be acquired,
and the audit logs to be appropriately managed.
The TOE implements this policy by the following Security Function:
(a) Security audit
When auditable security events occur, the TOE generates the audit logs that consist
of such items as event type, user identification, occurrence date and time, and
JISEC-CC-CRP-C0712-01-2021
16
outcome, etc., to add and save to the audit logging file. Only successfully
authenticated MFP administrators are allowed to read and delete the generated
audit logging file. Reading the audit logging file is executed by text format through a
Web browser of client computers.
In addition, in order to record the occurrence date and time of the audit event log, the
date and time information are acquired from the system clock of the TOE.
(4) Means to support Organisational Security Policy, "P.INTERFACE.MANAGEMENT"
This security policy requires that external interfaces (Operation Panel, LAN interface,
USB interface, and telephone lines) of the TOE are appropriately managed without
being used by unauthorised persons.
The TOE implements this policy by the following Security Functions:
(a) User identification and authentication
Based on the user identification and authentication described in Section 3.1.1.2,
whether a person who attempts to use the TOE is an authorised user will be verified
with reference to the identification and authentication information obtained from the
user. A person is provided with the user privileges that are set in advance in
accordance with the role assigned to the user, so that the authorised person is
allowed to use the TOE only if the person is confirmed as an authorised user.
(b) Restricted forwarding of data to external interfaces
This function is not an implementation for active mechanism, but is addressed as
architectural design of external interfaces. By its architecture, any information
received from an external interface is processed by the TSF, and any information
sent to an external interface is controlled by the TSF. Thus, unauthorised forwarding
of data between the different external interfaces is prevented.
As for USB interfaces, unauthorised forwarding of data by using this interface is
prevented by deactivating the use of USB interfaces.
(5) Means to support Organisational Security Policy, "P.STORAGE.ENCRYPTION"
This security policy requires that the TOE encrypts the stored contents on the HDD
inside the TOE.
The TOE implements this policy by the following Security Functions:
(a) Stored data protection function
The encryption and decryption by AES are performed for all data written into or
reading out to the HDD. When encrypting and decrypting the data, the key of
256-bits length is used. The key is created from the administrator setting an initial
value and stored in the TOE.

4. Assumptions and Clarification of Scope
This chapter describes the assumptions and the operational environment to operate the
TOE as useful information for the assumed readers to determine whether to use the TOE.
4.1 Usage Assumptions
Table 4-1 shows assumptions to operate the TOE. Although the assumptions in Table 4-1
are expressed differently from the conformance PP, the evaluation process confirmed the
equivalence of both assumptions.
The effective performances of the TOE security functions are not assured unless these
assumptions are satisfied.
Table 4-1 Assumptions in Use of the TOE
Identifier Assumptions
A.ACCESS.MANAGED
(Access management)
According to the guidance document, the TOE is placed
in a restricted or monitored area that provides
protection from physical access by unauthorised
persons.
A.USER.TRAINING
(User training)
The responsible manager of MFP trains users according
to the guidance document so that users are aware of the
security policies and procedures of their organisation
and are competent to follow those policies and
procedures.
A.ADMIN.TRAINING
(Administrator
training)
Administrators are aware of the security policies and
procedures of their organisation, and are competent to
correctly configure and operate the TOE in accordance
with the guidance document following those policies and
procedures.
A.ADMIN.TRUST
(Trusted administrator)
The responsible manager of MFP selects administrators
who do not use their privileged access rights for
malicious purposes according to the guidance document.
4.2 Environmental Assumptions
The TOE is installed in a general office and connected to a local area network (hereinafter
referred to as "LAN"), and it is used through the Operation Panel of the TOE itself and
client computers that are also connected to the LAN. Figure 4-1 shows the general
operational environment as assumptions of the TOE.
JISEC-CC-CRP-C0712-01-2021
18
Figure 4-1 Operational Environment of the TOE
Figure 4-1 gives an example environment to handle office documents in general offices
where the TOE is assumed to be used. The TOE is connected to the LAN and telephone
lines.
When the TOE is connected to the LAN that is connected to an external network such as
the Internet, firewalls are installed at the boundaries between the external network and
the LAN to protect the LAN and the TOE from attacks that originate from the external
network. The LAN is connected to server computers such as an FTP server, an SMB server,
and an SMTP server, and is connected to client computers. The LAN performs the
communication for the TOE to gather data such as documents and a variety of information.
The operation of the TOE includes both cases of using the Operation Panel of the TOE and
using client computers. Installing the printer drivers or the fax drivers in client computers
enables to process printing via the local area network from the client computers.
The following devices are assumed to be used on the operational environment:
- Client PC
> OS: Windows 8.1/10
> Web browser: Internet Explorer11, or Microsoft Edge 44
JISEC-CC-CRP-C0712-01-2021
19
> Printer driver: PCL6 Driver 1.0.0.0
> Fax driver: LAN Fax Driver 9.5.0.0
- SMTP server: Windows Server 2012 P-Mail Server Manager
- FTP server: Windows Server 2012 (IIS8), Linux (Fedora20) vsftpd
- SMB server: Windows Server 2012
Although the reliability of hardware and software shown in this configuration is outside the
scope of this evaluation, it is assumed to be trustworthy.
Table 4-2 shows the associated users to use of the TOE in this environment.
Table 4-2 TOE Users
User Definition Explanation
Normal user A user who is allowed to use the TOE. A
normal user is provided with a login user
name and can use normal functions of MFP.
Administrator Supervisor A user who is authorised to modify the login
password of the MFP administrator.
MFP
administrator
A user who is allowed to manage the TOE
and performs the management operations
such as normal user management, device
management, file management, and
network management.
As shown in Table 4-2, the TOE users are classified into normal user and administrator.
According to the roles, administrators shall be identified as supervisor and MFP
administrator. The users shown in Table 4-2 are direct users of the TOE. There is also a
responsible manager of the MFP who, as an indirect TOE user, is authorised to select the
MFP administrator and supervisor. The responsible manager of the MFP is assumed to be
an organisational manager in the operational environment.
4.3 Clarification of Scope
To protect data on communication paths between client computers/each server and the TOE,
it is necessary that communication protocols on client computers and each server are
operated securely to work properly.
To operate client computers and each server securely is the responsibility of the operator.

7. Evaluation conducted by Evaluation Facility and Results
7.1 Evaluation Facility
ECSEC Laboratory Inc., Evaluation Center 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
Evaluation was conducted by using the evaluation methods prescribed in the CEM in
accordance with the assurance requirements in the CC Part 3. 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 of each work unit in the CEM.
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 2019-12 and concluded upon completion of the Evaluation
Technical Report dated 2021-02. 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. For the development sites, site visits have
been omitted, and the Evaluation Facility determined with its responsibility that the
examination details on those of the past CC-certified products could be reused.
Furthermore, the evaluator conducted the sampling check of the developer testing and the
evaluator testing by using the developer testing environment at the Evaluation Facility or
the developer site in 2020-10 and 2020-12.
Concerns found in evaluation activities were issued as the Observation Report 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 they were sent to the Evaluation Facility. After the
Evaluation Facility and the developer examined them, those were reflected in the
Evaluation Technical Report.

7.4 IT Product Testing
The evaluator confirmed the validity of the testing that the developer had performed. As
the verification results of the evidence shown in the evaluation process and the testing
performed by the developer, the evaluator performed the reproducibility testing, additional
testing and penetration testing based on vulnerability assessments judged to be necessary.
7.4.1 Developer Testing
The evaluator evaluated the integrity of the developer testing that the developer had
performed and the documentation of actual test results. The content of the developer
testing evaluated by the evaluator is explained as follows.

Multiple MFP models are identified as the TOE in the ST. The differences between the
models are printing speed, types of Paper Output Unit, and display depending on
destination.
The TOE used in the developer testing is only a part of the identified models, however,
these models cover all the required printing speeds, types of Paper Output Unit, and
displays depending on destination.
Therefore, the evaluator judged that the developer testing was performed in the TOE
testing environment consistent with the TOE configuration identified in the ST.
2) Summary of the Developer Testing
A summary of the developer testing is as follows.
a. Developer Testing Outline
An outline of the developer testing is as follows.
<Developer Testing Approach>
The testing approaches consisted of:
- stimulating the assumed external interfaces (Operation Panel, Web browser, and so on)
in normal use of the TOE, and visually observing the results;
- analysing the generated audit log and the logging data for debug;
- checking the communication protocols between client computers/each server and the
TOE with packet capture; and
- executing anomaly simulation tests to generate abnormal events by altering a part of
the TSF implementation, and so on.
<Developer Testing Tool>
Table 7-2 shows the tool used for the developer testing.

<Content of the Performed Developer Testing>
The expected values of testing results described in testing specifications which are provided
in advance by the developer were compared to the values of the actual developer testing
results described in the testing result reports which are also provided by the developer. As a
result, it was found that the values of the actual testing results are in conformity to those of
the expected testing results.
b. Scope of the Performed Developer Testing
The developer testing was performed on about 500 items by the developer.
By the coverage analysis, it was verified that all security functions and external interfaces
described in the functional specification had been tested.
c. Result
The evaluator confirmed the approach of the performed developer testing and the validity of
tested items, and confirmed consistencies between the testing approach described in the
testing plan and the actual testing approach.
The evaluator confirmed consistencies between the expected test results by the developer
and the actual test results performed by the developer.
7.4.2 Evaluator Independent Testing
The evaluator performed the sample testing to reconfirm the implementation of security
functions using the test items extracted from the developer testing. In addition, the
evaluator performed the evaluator independent testing (hereinafter referred to as the
"independent testing") to gain further confidence that security functions are certainly
implemented, based on the evidence shown in the process of the evaluation.
The independent testing performed by the evaluator is explained as follows.
1) Independent Testing Environment
The configuration of the independent testing performed by the evaluator was the same as
the configuration of the developer testing as shown in Figure 7-1.
2) Summary of the Independent Testing
A summary of the independent testing is as follows.
a. Viewpoints of the Independent Testing
Viewpoints of the independent testing are shown below, which are devised by the evaluator
based on the analysis of developer testing and the evaluation documentation provided.
<Independent Testing Viewpoints>
JISEC-CC-CRP-C0712-01-2021
29
1. For TSFI that has many types of input parameters and to which the developer testing is
insufficient in terms of completeness, the testing items such as parameter scheme,
boundary values, and abnormal values are added.
2. For execution timing of several TSFs and combination of execution, the testing items to
which conditions are added are performed.
3. The testing items to which the different variation from the developer testing is added
are performed in regard to procedures of exception and cancellation.
4. The testing items are selected in the sampling testing from the following viewpoints:
- The testing items are selected to include all of TSFs and TSFIs in terms of
completeness.
- The testing items are selected to cover the different testing approaches and testing
environments.
- The testing items involving TSFI that meet many of the SFRs are mainly selected in
order to conduct tests efficiently.
b. Independent Testing Outline
An outline of the independent testing that the evaluator performed is as follows.
<Independent Testing Approach>
In setting the different initialisation and the different parameters from the developer
testing, the independent testing approaches consisted of:
- stimulating the assumed external interfaces (Operation Panel, Web browser, and so on)
in normal use of the TOE, and visually observing the results;
- analysing the generated audit log; and
- checking the communication protocols between client computers/each server and the
TOE with packet capture, and so on.
<Content of the Performed Independent Testing>

c. Result
All the independent testing performed by the evaluator was correctly completed, and the
evaluator confirmed the behaviour of the TOE. The evaluator confirmed consistencies
between the expected behaviour and all the test results.
7.4.3 Evaluator Penetration Testing
The evaluator devised and performed the necessary evaluator penetration testing
(hereinafter referred to as the "penetration testing") on the potentially exploitable
JISEC-CC-CRP-C0712-01-2021
31
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 evaluator is explained as follows.
1) Summary of the Penetration Testing
A summary of the penetration testing performed by the evaluator is as follows.
a. Vulnerability of Concern
The evaluator 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. Unauthorised access to the TOE may be caused by unexpected interfaces.
2. Security Functions may be bypassed in case of entering data, for interfaces, which have
the values and formats that are unintended by the TOE.
3. There may be some vulnerabilities when implementing secure channels, and
consequently the Security Functions of the TOE may be bypassed.
4. Security Functions may be bypassed by maintaining the TOE overloaded.
b. Penetration Testing Outline
The evaluator performed the following penetration testing to identify potentially
exploitable vulnerabilities.
<Penetration Testing Environment>
The penetration testing configuration is identical with those of the developer testing shown
in Figure 7-1, and evaluator independent testing.

c. Result
In the penetration testing performed by the evaluator, the evaluator did not find any
exploitable vulnerabilities that attackers who have the assumed attack potential could
exploit.
7.5 Evaluated Configuration
The configuration conditions of the TOE, which are the prerequisites for this evaluation,
are described in the guidance documents listed in Chapter 6. In order to enable the security
functions of the TOE and use them securely, the TOE must be set as described in the
guidance documents. Different settings from those described in the guidance documents are
not subject to the assurance of this evaluation.

As a result of verification of the Evaluation Technical Report, the Observation Report and
related evaluation documentation submitted by the Evaluation Facility, the Certification
Body determined that the TOE evaluation satisfies all assurance requirements for EAL2
augmented by ALC_FLR.2 in the CC Part 3.
8.2 Recommendations
Any influences on the security functions of the TOE in the operation, in the case the
Maintenance Functions are activated, are out of the scope of the assurance provided by this
evaluation. Therefore, it is advised to make a judgment at the administrator's
responsibility about the acceptance of maintenance.
It should be noted that the TOE users need to refer to the description of "4.3 Clarification of
Scope" and to see whether or not the evaluated scope of the TOE and the operational
requirement items can be handled in the actual operating environment of the TOE.
To make sure of the TOE identification, checking the sticker on the surface of package as
well as display of the TOE should be required, as described in Chapter 2. Be sure to keep
the information described on this sticker to certainly identify the TOE.
