3. Security Policy
This chapter describes security function policies that the TOE adopts to counter threats,
and organizational security policies.
In addition to offering MFP capabilities such as Copy, Print, and Scan, the TOE is capable of
storing user document data in its internal HDD, and has the functionality for interacting
with user terminals and various servers over the network.
The PP, to which the TOE is conformant, assumes an environment where a relatively high
level of security is ensured and where accountability for actions is required, and specifies
the security functional requirements for such an environment.
When using the MFP functions, the TOE offers security functions that satisfy the security
functional requirements specified in the PP. These include user identification and
authentication, access control, HDD data encryption, data erase functions, and
cryptographic communication protocols, and protect user document data and setting data
that have an effect on TOE security functions, which are TOE assets, from unauthorized
disclosure and alteration.
In terms of the use of the TOE, the following roles are assumed.
- U.NORMAL
A User who is authorized to perform User Document Data processing functions of the
TOE, such as Copy, Print, and Scan.
- U.ADMINISTRATOR
The TOE user in this role has special privileges that allow configuration of security
functions.
- TOE Owner
A person or organizational entity responsible for protecting TOE assets and
establishing related security policies.
The TOE assets are defined as follows.
- User Document Data
User Document Data consist of the information contained in a user’s document.
- User Function Data
User Function Data are the information about a user’s document or job to be processed
by the TOE. This includes information such as print priority and print settings.
- TSF Confidential Data
TSF Confidential Data are data used by the security functions, and for which integrity
and confidentiality must be preserved. This includes information such as user password,
Box PIN, and audit logs. This does not, however, include cryptographic keys, since the
user has no interface available to its access.
- TSF Protected Data
TSF Protected Data are data used by the security functions, and for which only
integrity must be preserved. This includes information such as user identification and
access privilege information.
CRP-C0474-01

3.1 Security Function Policies
The TOE provides the security functions to counter the threats shown in Section 3.1.1 and
to satisfy the organizational security policies shown in Section 3.1.2.
3.1.1 Threats and Security Function Policies
3.1.1.1 Threats
The TOE assumes the threats shown in Table 3-1 and provides the functions to counter
them. These threats are the same as those specified in the PP.
Table 3-1 Assumed Threats
Identifier Threat
T.DOC.DIS User Document Data may be disclosed to unauthorized persons.
T.DOC.ALT User Document Data may be altered by unauthorized persons.
T.FUNC.ALT User Function Data may be altered by unauthorized persons.
T.PROT.ALT TSF Protected Data may be altered by unauthorized persons.
T.CONF.DIS TSF Confidential Data may be disclosed to unauthorized persons.
T.CONF.ALT TSF Confidential Data may be altered by unauthorized persons.
3.1.1.2 Security Function Policies against Threats
The TOE counters the threats shown in Table 3-1 by the following security function policies.
(1) Countermeasures against threat “T.DOC.DIS,” “T.DOC.ALT,” “T.FUNC.ALT”
These are threats to user data. The TOE counters the threats by the following functions:
“User Authentication,” “Function Use Restriction,” “Job Output Restriction,” “HDD Data
Erase,” “HDD Data Encryption,” and “LAN Data Protection.”
“User Authentication” and “Function Use Restriction” functions of the TOE allow only the
authorized users to use the TOE functions. For details of these functions, refer to the
description of P.USER_AUTHORIZATION in Section 3.1.2.2.
“Job Output Restriction” function of the TOE enforces access control when an identified
and authenticated user performs the operation such as Print, Preview, Send to Network,
Fax TX (send), Delete, Change Print Priority, and Change Print Settings on print jobs and
I-fax jobs stored in the TOE or document data stored in a box, thereby ensuring that only
the owner of the documents or U.ADMINISTRATOR gains access to perform these
operations. The TOE determines that the identified and authenticated user is the
authorized document owner as follows:
- For documents submitted as print jobs, the identified and authenticated user is
determined to be the owner of the document if his/her user name matches the user
name information of the document specified upon submission of the print job.
CRP-C0474-01
7
- For document data stored as a result of scanning or received by I-fax, the user is
required to enter the correct box PIN when the user operates the document data.
The boxes where these document data are stored are assigned per user, and
pre-configured with a 7-digit box PIN. If the user enters the correct PIN, then the
user is determined to be the owner of the document data stored in the box.
“HDD Data Erase” function of the TOE permanently erases the HDD area where the
document data are stored, by overwriting with random data upon deleting the document
data, to prevent the deleted document data from being read from the HDD.
“HDD Data Encryption” function of the TOE encrypts all data stored in the removable
HDD of the TOE, and prevents the data from being disclosed or altered by tampering the
detached HDD from the TOE. It uses the 256-bit AES encryption algorithm. Its
cryptographic key is generated using the FIPS PUB 186-2 deterministic random number
generator algorithm at start-up, and destroyed upon power-off.
“LAN Data Protection” function of the TOE uses the cryptographic communication
protocol, IPsec, when the TOE communicates with other IT devices over the LAN, and
protects the communicated data from unauthorized disclosure and alteration.
With the above functions, the TOE prevents unauthorized use of the TOE, unauthorized
access to data stored in the HDD and communication data; thus, the TOE protects the
data to be protected from unauthorized disclosure and alteration.
(2) Countermeasures against threat “T.PROT.ALT,” “T.CONF.DIS,” “T.CONF.ALT”
These are threats to TSF data that affects the security functions. The TOE counters the
threats by the following functions: “User Authentication,” “Management,” “HDD Data
Encryption,” and “LAN Data Protection.”
“Management” function of the TOE allows only the authorized U.ADMINISTRATOR to
manage user information and various configuration data. Note, however, that the
authorized U.NORMAL can change their own passwords and the PIN for the mail box
they use.
“User Authentication,” “HDD Data Encryption,” and “LAN Data Protection” work as
described in (1).
With the above functions, the TOE prevents unauthorized use of the TOE, unauthorized
access to data stored in the HDD and communication data; thus, the TOE protects the
data to be protected from unauthorized disclosure and alteration.

3.1.2 Organizational Security Policies and Security Function Policies
3.1.2.1 Organizational Security Policies
The organizational security policies required in use of the TOE are shown in Table 3-2.
These organizational security policies are the same as specified in the PP except for addition
of P.HDD.ACCESS.AUTHORIZATION. P.HDD.ACCESS.AUTHORIZATION is augmented
for the PP under the assumption that it would generally be required to use a removable
HDD on the TOE.
Table 3-2 Organizational Security Policies
Identifier Organizational Security Policy
P.USER.AUTHORIZATION To preserve operational accountability and security,
Users will be authorized to use the TOE only as
permitted by the TOE Owner.
P.SOFTWARE.VERIFICATION To detect corruption of the executable code in the
TSF, procedures will exist to self-verify executable
code in the TSF.
P.AUDIT.LOGGING To preserve operational accountability and security,
records that provide an audit trail of TOE use and
security-relevant events will be created,
maintained, and protected from unauthorized
disclosure or alteration, and will be reviewed by
authorized personnel.
P.INTERFACE.MANAGEMENT To prevent unauthorized use of the external
interfaces of the TOE, operation of those interfaces
will be controlled by the TOE and its IT
environment.
P. HDD.ACCESS.AUTHORIZATION To prevent access TOE assets in the HDD with
connecting the other HCDs, the TOE will have
authorized access the HDD data.
3.1.2.2 Security Function Policies to Organizational Security Policies
The TOE provides the security functions to satisfy the organizational security policies
shown in Table 3-2.
(1) Means for organizational security policy “P.USER.AUTHORIZATION”
This policy is realized by “User Authentication” and “Function Use Restriction”
functions of the TOE.
“User Authentication” function of the TOE only permits the users who are successfully
identified and authenticated to use the TOE. To enhance the identification and
authentication mechanism, the TOE enforces a password policy to use passwords of a
certain minimum length containing a mixture of character types, and a lockout policy
whereby a lockout of certain duration is imposed upon a certain number of failed
authentication attempts.
CRP-C0474-01
9
Incoming print jobs or fax/I-fax jobs are accepted without requiring identification and
authentication. The resulting document data are stored within the TOE, and not
automatically printed out or transmitted. To print out or transmit document data
stored in the TOE, the users must operate the control panel of the TOE, which will
require identification and authentication.
“Function Use Restriction” function of the TOE performs access restriction on the use
of the TOE functions, so that only the identified and authorized users with appropriate
permissions are permitted to use the functions. For access restriction, users are
assigned “roles” which are bound to permission information. This information is used
to determine whether the use of the function is permitted to each user or not.
With the above functions, the TOE ensures that only the authorized users are
permitted to use the TOE.
(2) Means for organizational security policy “P.SOFTWARE.VERIFICATION”
This policy is realized by “Self-Test” function of the TOE.
“Self-Test” function of the TOE checks the integrity of the cryptographic algorithm and
the cryptographic key generation algorithm that are used by LAN Data Protection
function, after decrypting the executable code which is encrypted and stored in the
HDD, at start-up. Thereby the integrity of the executable code of the TOE security
functions is ensured.
Note that the self-test function does not check all executable codes of the TOE security
functions; however, the evaluator evaluates that if the integrity of the part of the TOE
security functions is verified, the integrity of all other executable codes decrypted by
the same mechanisms is also ensured.
(3) Means for organizational security policy “P.AUDIT.LOGGING”
This policy is realized by “Audit Log” function of the TOE.
“Audit Log” function of the TOE generates and stores audit logs in the TOE’s HDD at
the occurrence of security-relevant events when security functions are used. The stored
audit logs can be viewed by an authorized U.ADMINISTRATOR only, via a Web
browser.
(4) Means for organizational security policy “P.INTERFACE.MANAGEMENT”
This policy is realized by “User Authentication” and “Forward Received Jobs” functions
of the TOE.
“User Authentication” function of the TOE ensures that only identified and
authenticated users are allowed to use the TOE. Additionally, a session will be
terminated, if a user leaves the session inactive longer than the specified time.
“Forward Received Jobs” function of the TOE restricts data received from various
interfaces to be directly forwarded to the LAN without prior processing by the TOE.
These functions prevent the unauthorized use of the interfaces of the TOE.
CRP-C0474-01
10
(5) Means for organizational security policy “P.HDD.ACCESS.AUTHORIZATION”
This policy is realized by the Device Identification and Authentication function, which
is part of “HDD Data Encryption” function of the TOE.
The Device Identification and Authentication function in the “HDD Data Encryption”
function is provided by the HDD Data Encryption & Mirroring Board, one of the
components of the TOE. The HDD Data Encryption & Mirroring Board acquires the
device authentication ID from the MFP device when it is initially mounted. At each
start-up, it uses this information for a challenge and response method to confirm the
identity of the MFP device, and grants access to the HDD only if it successfully
confirms that it is mounted on the authorized MFP device.

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 the use of the TOE.
4.1 Usage Assumptions
Table 4-1 shows assumptions to operate the TOE. These assumptions are the same as
specified in the PP.
The effective performances of the TOE security functions are not assured unless these
assumptions are satisfied.
Table 4-1 Assumptions
Identifier Assumptions
A.ACCESS.MANAGED The TOE is located in a restricted or monitored
environment that provides protection from unmanaged
access to the physical components and data interfaces of
the TOE.
A.USER.TRAINING TOE Users are aware of the security policies and
procedures of their organization, and are trained and
competent to follow those policies and procedures.
A.ADMIN.TRAINING Administrators are aware of the security policies and
procedures of their organization, are trained and
competent to follow the manufacturer’s guidance and
documentation, and correctly configure and operate the
TOE in accordance with those policies and procedures.
* The meaning of "correctly configure" includes the
description specified in (1) and (2) of Section 8.2
"Recommendations."
A.ADMIN.TRUST Administrators do not use their privileged access rights
for malicious purposes.
4.2 Environmental Assumptions
The TOE is an MFP designed to operate in a typical office environment, where the MFP is
connected by an internal LAN, and the internal LAN is protected by Firewall, etc., from
threats from the external network. The assumed operational environment of the TOE is
shown in Figure 4-1.
TOE users can operate the TOE from its control panel, from a PC connected via USB, or
from a PC connected to the LAN.

Figure 4-1 Operational Environment of the TOE
The operational environment of the TOE consists of the following components.
(1) Fax Board (Optional for using FAX with 2 or more lines)
If necessary, the following fax boards can be attached to the TOE. These fax boards are
also outside the scope of the TOE.
- Canon Super G3 2nd Line Fax Board-AP1
- Canon Super G3 3rd/4th Line Fax Board-AL1
(2) PC
It is a generic PC used by a user to connect to the TOE, via USB or internal LAN. This
evaluation was performed using the following software.
- Printer driver: Canon LIPSLX Printer Driver Version 21.10
- Web browser: Microsoft Internet Explorer 8
(3) User Authentication Server
The TOE supports two methods of “User Authentication” of the TOE described in
Chapter 3: “Internal Authentication” where authentication takes place using user
information stored within the TOE, and “External Authentication” where authentication
takes place using user information stored in an external server.
The User Authentication Server is the server that is necessary for the TOE when using
External Authentication, and the authentication protocol to be used is either Kerberos or
LDAP.
This evaluation was performed using Active Directory Domain Service as the
CRP-C0474-01
13
authentication server software for Kerberos authentication, and using eDirectory 8.8
SP7 as the authentication server software for LDAP authentication.
(4) Mail Server
A Server is installed as required to facilitate the I-fax capability of the MFP.
(5) Time Server
It is the NTP service commonly provided over the Internet. As long as the environment
allows, it is recommended that a time server be configured in the TOE, to synchronize
the time in the MFP that is used as the time stamp of audit logs. Otherwise, the time
that is configured and maintained by the TOE’s Management function is used instead.
Note that the reliability of software and hardware other than the TOE shown in this
configuration is not subject to the evaluation.
4.3 Clarification of Scope
In this evaluation, it is considered that the security functional requirements for the
identification and authentication specified in the PP regarding the MFP’s Print function do
not apply to the operations on submitting print jobs; rather, they apply only to the
operations on document data accumulated in the MFP, created by the submitted print jobs.
As such, the following security functions are considered out of the scope of this evaluation.
(1) The TOE supports various print protocols for the submission of print jobs. Some
protocols have their own identification and authentication mechanisms, and those
mechanisms are out of the scope of this evaluation. Examples of this include the
identification and authentication mechanism in the IPP protocol or in the FTP protocol
for FTP print.
(2) When submitting a print job to the TOE through a print driver, the user is asked to
provide the user name and PIN. This input is not used by the identification and
authentication function. A PIN is associated with each document data submitted as a
print job, and the user must provide the correct PIN in order to print that data from the
control panel (this is known as “Secured Print”). This behavior is outside the scope of
this evaluation.
The user name is not authenticated for its validity, but is simply associated with the
submitted print job. The user name is used by the access restriction function for the
target of evaluation.

of the TOE described in Chapter 3, and the remaining components shown in white box
within the TOE are the basic functions of the MFP. For details on the basic MFP functions,
see Terminology in Chapter 11.
Users of the TOE operate the TOE from its control panel (“UI Func” in Figure 5-1), from a
PC connected to the LAN using a Web browser (“Web Browser” contained in “PC” in Figure
5-1), or from a PC connected via LAN or USB using a print driver (indicated only as the
“PC” and a print driver is not illustrated in Figure 5-1).
CRP-C0474-01
15
The security functions of the TOE are applied when the user uses basic MFP functions. The
following describes the relation between the security functions and the basic MFP functions.
(1) When a user submits a print job from a PC connected via LAN or USB, or when a
fax/I-fax job is received, the jobs are accepted without requiring identification and
authentication, and the resulting document data are stored within the TOE. The user
may perform operations on the document data in the TOE later, using the control panel
or from a Web browser.
When the user attempts to access the basic MFP functions from the control panel or
from a Web browser, “User Authentication” and “Function Use Restriction” functions
are applied, so that only authorized users are allowed to use the TOE. Subsequently,
when the user attempts to execute an operation on a document data stored in the TOE,
“Job Output Restriction” function is applied, so that only the owner of the document
data or the Administrator is allowed to operate the document data.
When the user attempts to use “Management” function or browse audit logs provided
by “Audit Log” function from the control panel or a Web browser, “User Authentication”
function is applied, so that only the identified and authenticated users with
Administrator privileges can gain access to the TOE.
Note that audit logs are generated by “Audit Log” function when these security
functions are used.
(2) In the use described in (1) above, “HDD Data Encryption” function is applied to all data
stored in the internal HDD, and “HDD Data Erase” function is applied when document
data are deleted.
(3) In the use described in (1) above, “LAN Data Protection” function is applied when the
TOE communicates with other IT devices over the LAN. In addition, “Forward Received
Jobs” function restricts data received from various interfaces to be forwarded without
any TOE security functions applied.
5.2 IT Environment
When the external authentication method is used for “User Authentication” function of the
TOE, Kerberos or LDAP protocol is used to query the information contained in the User
Authentication Server to perform user identification and authentication. User account
information is registered in the User Authentication Server through the management
function of the User Authentication Server.
The time information recorded on the TOE’s audit logs is provided by the TOE. The time
information of the TOE is set and maintained by the Management function of the TOE, or
can be synchronized with an external time server using the NTP protocol.
The TOE uses IPsec protocol to communicate with other external IT devices over the
network. As such, those external IT devices need to have IPsec protocol configured as well.

7. Evaluation conducted by Evaluation Facility and Results
7.1 Evaluation Facility
Mizuho Information & Research Institute, Inc., Information Security Evaluation Office 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 is agreed on mutual recognition with 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 components 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 has started on 2013-03 and concluded upon completion of the Evaluation
Technical Report dated 2015-05. 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. Additionally, the evaluators directly visited
the development and manufacturing sites on 2013-06 and examined procedural status
conducted in relation to each work unit for configuration management, delivery and
development security, by investigating records and interviewing staff. Furthermore, the
evaluators conducted the sampling checks of the developer testing and the evaluator testing
by using the developer testing environment at the developer site on 2015-03 and 2015-04.
Concerns found in the evaluation activities for each work unit were all issued as the
Observation Reports, and those were reported to the developer. Those concerns were
reviewed by the developer, and all the concerns were solved eventually.
Concerns that the Certification Body found in the evaluation process were described as the
certification oversight reviews, and those were sent to the Evaluation Facility.
After the Evaluation Facility and the developer examined them, those concerns 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 a
result of the evidence shown in the process of the evaluation and the verification results of
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 performed
and the documentation of the actual testing results. The content of the developer testing
evaluated by the evaluator is explained as follows.
1) Developer Testing Environment
The TOE used in the developer testing is iR-ADV 4251 model with the same TOE
identification described in Chapter 2. The evaluator evaluated that it was sufficient to
test a representative model only, since the differences between the MFP models were
hardware performances such as scanning and printing speeds, and there was no
difference in the behavior of the security functions. Note that the evaluator tested other
MFP models that were not tested by the developer to verify machine independence. For
details, see Section 7.4.2, Evaluator Independent Testing.
Details of the non-TOE components of the developer testing environment are given in
Table 7-1. The configuration for this testing is the operational environment of the TOE as
described in Figure 4-1, except for the following differences. Besides these differences,
this configuration is identical to the configuration specified in the ST, and the evaluator
evaluates that these differences do not affect the purpose, which is to test the TOE’s
functions.
- Although included in the description in the ST, no firewall is used in the testing
environment since it was not connected to the Internet.
- The fax machine (see Table 7-1) is connected to the fax board via a pseudo-exchanger
instead of the public switched telephone network (PSTN).
- Either “User Authentication Server 1” or “User Authentication Server 2” is used as
the User Authentication Server, depending on the protocol used for external
authentication.
- The Internet Time Server is substituted with the software on the “Time Server.”
- The optional fax board (2nd line or more) is attached to the MFP.

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>
(1) By operating the user interfaces such as control panel, Web browser, and printer
driver, the developer confirms the output messages of the user interfaces, the TOE’s
behavior, and the contents of audit logs.
(2) To confirm the HDD Data Erase function, the developer uses the HDD protocol
analyzer to read the deleted contents of the HDD to confirm that the contents are
overwritten with the specified data.
(3) To confirm the HDD Data Encryption function, the developer compares the
encrypted data stored in the HDD with the result of the data encrypted by another
tool, and confirms that the TOE implements the cryptographic algorithm according
to the specification. For the cryptographic key generation, the developer also
CRP-C0474-01
20
compares the results of random numbers that were generated using various seed
values with the known data, and confirms that the TOE implements the
cryptographic key generation algorithm according to the specification.
(4) To confirm the IPsec function, the developer confirms that IPsec communication is
established with the PC and that IPsec communication properly functions. The
developer also confirms that the cryptographic communication protocol is applied
according to the specification by using a network analyzer.
(5) To confirm the Device Identification and Authentication function of the HDD Data
Encryption & Mirroring Board, the developer checks its behavior when mounted on
the MFP with the correct ID as well as when mounted on a MFP with an incorrect
ID.
(6) To confirm that inputs to the Web server (TOE) are checked by the TOE, the
developer observes the behavior of the TOE when the inputs from the Web browser
to the Web server (TOE) are changed by using a tool as well as the outputs.
<Developer Testing Tools>
The tools used for the developer testing are shown in Table 7-2 below.

<Content of the Performed Developer Testing>
It was confirmed that the security functions to be applied to various input parameters
operate according to the specification by operating the basic MFP functions and
security management functions from various interfaces. It was also confirmed that all
acceptable setting values for the evaluated configuration such as internal or external
authentication settings operate according to the specification.
b. Scope of the Performed Developer Testing
The developer testing was performed on 398 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 sufficiently tested. By the depth analysis, it was
verified that all subsystems and subsystem interfaces described in the TOE design had
been sufficiently tested.
c. Result
The evaluator confirmed the approach of the performed developer testing and the
legitimacy of tested items, and confirmed the consistency between the testing approach
described in the testing plan and the actual testing approach. The evaluator confirmed
the consistencies between the testing results expected by the developer and the actual
testing results performed by the developer.
7.4.2 Evaluator Independent Testing
The evaluator performed the sample testing to reconfirm the execution of the security
functions by the test items extracted from the developer testing, and the evaluator
performed the evaluator independent testing (hereinafter referred to as the “independent
testing”) to gain further assurance 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 testing performed by the evaluator is the same as the
configuration of the developer testing. The specification confirmation, behavior tests, and
calibration for the devices and testing tools used were performed by the evaluator.
The TOEs tested by the evaluator are iR-ADV 4251 and iR-ADV 4225 among the models
with the same TOE identification described in Chapter 2.
The independent testing was performed in the same environment as TOE configuration
identified in the ST.
2) Summary of Independent Testing
A summary of the performed independent testing is as follows.
a. Independent Testing Viewpoints
The evaluator devised the independent testing in terms of the following viewpoints,
based on the developer testing and the provided evaluation documentation, in order for
the evaluator him/herself to demonstrate that the TOE security functions work as
CRP-C0474-01
22
specified.
<Independent Testing Viewpoints>
(1) By testing other models that were not tested by the developer, the evaluator
confirms that the differences between the models are those of hardware
performance (i.e., processing speed) only, and the differences do not affect the
behavior of the security functions.
(2) The evaluator confirms that the TOE functions properly operate regardless of
the situation of optional 2nd or more fax boards being installed.
(3) In terms of the sampling of the developer testing, the evaluator performs the
same testing as the developer testing performed, by extracting test items so that
all TSFI and security functions are included.
(4) In the developer testing, there are some interfaces that were not rigorously
tested to examine the behavior of the security functions, so the evaluator
confirms the behavior using the parameters that were not yet tested.
b. Independent Testing Outline
An outline of the independent testing that the evaluator performed is as follows.
<Independent Testing Approach>
Using the same approach as that of the developer testing, the same testing and the
testing with changed parameters were conducted.
<Independent Testing Tools>
The same testing tool as that of the developer testing was used.
<Content of the Performed Independent Testing >
Table 7-3 shows viewpoints of the independent testing conducted by the evaluator with
the corresponding testing contents. Note that while the developer testing covered all
setting values, the evaluator testing was performed using the default setting values
that were set immediately after completing all installation procedures.
Table 7-3 Independent Testing Performed

(1) (3) Based on the viewpoints, test items were extracted from the
developer testing, and the same tests were repeated to
determine that the same results can be obtained. Out of a total
of 398 test items, 159 test items were tested.
(2) In a state where the optional 2nd or more fax boards are NOT
being installed, or where the optional 2nd fax board is being
installed, the same tests as the one conducted by the developer
were conducted. By selecting the tests related to the fax
function, the evaluator confirmed that there was no difference,
except for the number of fax lines.

testing
Outline of independent testing
(4) The evaluator confirmed that the behavior of the threshold
values of the length of the user password, box PIN, or password
for machine maintenance was according to the specification.
(4) The TOE provides multiple roles available as U.NORMAL. The
evaluator confirmed that whatever the role a user was assigned
for U.NORMAL, the user would not be able to use the
management functions only for U.ADMINISTRATOR according
to the specification.
(4) The evaluator confirmed that the behavior was as expected,
when a secured print job is submitted using a user name that is
not registered in the TOE.
(i.e., The Administrator can browse or delete all secured print
jobs. A non-Administrator cannot operate because the access is
denied as the user name will not match.)
(4) The evaluator confirmed that a log of the transmission error was
generated according to the specification, if a document stored in
a box was being transmitted to the network, and the LAN cable
was unplugged.
(4) The evaluator confirmed that the HDD Data Erase function
properly operated, even when fax transmission was interrupted
due to a problem outside the TOE.
(4) The evaluator confirmed that no IPsec connection was
established, when IPsec was not properly configured (i.e., no
encryption, or a weak cryptographic algorithm was specified) on
the connected PC.
(4) The evaluator confirmed that a special function for maintenance
would not become available by the specific operation that does
not need identification and authentication.
(4) When using different Secured Print settings, the evaluator
confirmed that the user authentication function would not be
affected.
(4) In the tests to change the input from the Web browser to the
Web server (TOE) using tools, the evaluator confirmed that
input checks were properly conducted by adding a negative
number as an input, which was considered as an incorrect value,
when the type and number of the input characters were different
from those used in the developer testing.
c. Result
All the independent testing performed by the evaluator was correctly completed, and
the evaluator confirmed the behavior of the TOE. The evaluator confirmed the
consistencies between the expected behavior and all the testing 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
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 below.
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.
Note that for cryptographic keys, the evaluator determines that attackers with the
assumed attack potential cannot obtain or guess the cryptographic key, based on the
mechanism used at TOE start-up to generate the cryptographic key and the analysis of
the developer testing for that mechanism.
(1) There is a concern corresponding to the TOE regarding the publicly available
vulnerability information, such as the possibility of unauthorized use of network
service, various vulnerabilities on the Web.
(2) There is a concern in Web interfaces that identification and authentication or
access control mechanisms may be bypassed if the URL is directly specified or
session management information is guessed.
(3) There is a possibility that the information on the TOE is acquired or tampered
without authorization by exploiting the language used for the print job.
(4) There is a concern that the TOE unexpectedly operates when powered OFF/ON
during start-up or shut-down.
(5) There is a concern that the TOE operates unexpectedly when the same document
data is simultaneously accessed from the control panel and from a Web browser.
(6) There is a concern that the TOE unexpectedly operates when the TOE’s resources
such as disk space are exhausted.
(7) There is a concern that a security may be compromised when the TOE is
activated with a special operation for maintenance if some operation is made in
that state.
b. Penetration Testing Outline
The evaluator performed the following penetration testing to identify potentially
exploitable vulnerabilities.
< Penetration Testing Environment>
The penetration testing was conducted in the same environment as the evaluator
independent testing. The TOE used as the target of this test is iR-ADV 4235F.
CRP-C0474-01

The penetration testing was performed by using an additional PC with the penetration
testing tools. Details of the tools used are provided in Table 7-4 as follows. The
specification confirmation, behavior tests, and calibration for these tools were
performed by the evaluator

(1) - Using Nessus and nmap on the TOE, the evaluator searched
for any open ports and vulnerabilities, and confirmed that no
unexpected ports were open and that no publicly-known
vulnerabilities exist on the open ports.
- Using Nikto and OWASP ZAP, the evaluator searched for
vulnerabilities in the TOE’s Web server function, and
confirmed there were no publicly-known vulnerabilities.
(2) - In the Web browser’s login screen, the evaluator attempted
bypass login by directly specifying the URL without login, and
confirmed that login could not be bypassed.
- During login from the Web browser to the TOE, the evaluator
obtained multiple session information using TamperIE, and
confirmed those were random numbers that could not be
guessed by an attacker possessing the assumed attack
potential.

Outline of the Penetration Testing
(3) - A job with a concern for the acquisition and/or tampering of
data without authorization was created based on the grammar
of the language used for print jobs and sent to the TOE. It was
confirmed that no acquisition and/or tampering of the data
without authorization was possible.
(4) - It was confirmed that when the TOE was powered OFF during
start-up, the TOE shut down properly showing no abnormal
behavior.
- It was also confirmed that when the TOE was powered ON
during shutdown, the TOE started up after shutting down,
showing no abnormal behavior.
(5) - It was confirmed that when the same document was accessed
simultaneously from the control panel and a Web browser, one
with the intent to delete the document, the other to merge and
save under the same file name, the former delete operation and
the latter save operation succeeded, showing no abnormal
behavior.
(6) - When the HDD was full, the evaluator attempted to save
additional data, and confirmed that it resulted in error,
showing no abnormal behavior.
- Similar tests were performed to check the maximum number of
registered users and secured print jobs, showing no abnormal
behavior.
(7) - When the TOE was activated with a special operation for
maintenance, the evaluator tried various operations possible
from the operation panel and network and confirmed that no
abnormal behavior was observed.
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 conditions for the evaluated configuration of the TOE in this evaluation are as
described in the guidance documents, and users must follow the guidance documents to set
up the TOE. Some of the settings are fixed in this evaluation, because certain settings such
as disabling security functions weaken security. If any settings that affect security are
changed to the value that is advised not to set in the guidance documents, then the MFP
with those settings is no longer the evaluated configuration.
CRP-C0474-01

8. Certification
The Certification Body conducted the following certification based on the materials
submitted by the Evaluation Facility during the evaluation process.
1. Contents pointed out in the Observation Reports shall be adequate.
2. Contents pointed out in the Observation Reports shall properly be solved
3. The submitted documentation was sampled, the content was examined, and the related
work units 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.
Concerns found in the certification process were prepared as the certification oversight
reviews, and they 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 submitted Evaluation Technical Report, Observation
Reports, and related evaluation documentation, the Certification Body determined that the
TOE satisfies all assurance requirements for EAL3 augmented with ALC_FLR.2 in the CC
Part 3.
8.2 Recommendations
(1) This evaluation was performed with use of the fax inbox function disabled. If the use of
fax inbox is enabled, then that is no longer the evaluated configuration.
(2) In terms of the security functional requirements specified in the PP, this evaluation
acknowledges that the requirements for identification and authentication do not apply
to incoming print jobs. Consumers expecting identification and authentication to be
enforced for incoming print jobs are therefore advised to take note that the TOE
specification may not be consistent with their needs.
(3) When external authentication is used in the TOE, Kerberos or LDAP can be used to
communicate with the user authentication server. Where this is the case, the assurance
provided by this evaluation specifically applies only when Kerberos with Active
Directory Domain Services or LDAP with eDirectory 8.8 SP7 is used as the
authentication server software.
