This chapter describes security function policies that the TOE adopts to counter threats,
and organizational security policies.
The TOE provides the basic MFD functions such as copy, print, network scan, and fax, and
has functions to store the user document data in the TOE's internal HDD and to
communicate with user clients and various servers via network.
When those MFD functions are used, the TOE provides security functions that fulfill the
security functional requirements required by the Protection Profile for MFDs, U.S.
Government Approved Protection Profile - U.S. Government Protection Profile for
Hardcopy Devices Version 1.0 (IEEE Std. 2600.2TM
-2009) [14][15] (hereinafter referred to
as the "PP"). The security functions that the TOE provides include
identification/authentication and access control of users, encryption of the document data
stored in HDD, data overwrite at deleting the document data in HDD, and encryption
communication. The TOE prevents the user's document data and the setting data affecting
security that are assets to be protected from being disclosed or altered by unauthorized
persons.
The TOE assumes the following user roles:
- General User
Any person who uses the basic MFD functions, such as copy
, print, network scan, and fax,
provided by the TOE.
- System Administrator
A user who has been specifically granted the authority to configure settings of the TOE
security functions. System administrator includes "key operator" who can use all the
management functions, and "SA (system administrator privilege)" who can use a part of
the management functions.
- TOE Owner
Any person or organizational entity responsible for protecting TOE assets and
establishing the security objectives for the TOE operating environment.
- Customer Engineer
Customer service engineer who maintains and repairs the MFD.
The TOE's assets to be protected are 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 job to be processed by the TOE.
- TSF Confidential Data
TSF Confidential Data are the data used for security functions, and whose integrity and
confidentiality are required. In the definition of the TOE, they include passwords of users,
the setting values of encryption communication protocol, and the audit logs.
- TSF Protected Data
TSF Protected Data are the data used for security functions, and whose integrity only is
required. In the definition of the TOE, they include the setting values of security
CRP-C0590-01
10
functions excluding TSF Confidential Data. For example, TSF Protected Data include
user IDs, information on user permission for the basic functions, information on the
owners of document data, etc.
3.1 Security Function Policies
The TOE possesses the security functions to counter the threats shown in Chapter 3.1.1,
and to satisfy the organizational security policies shown in Chapter 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 security functions to
counter them. These threats are the same as those described 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.

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.
Details of each security function are shown in Chapter 5.
1) Countermeasures against threat "T.DOC.DIS," "T.DOC.ALT" and "T.FUNC.ALT"
These are threats to user data (User Document Data and User Function Data). The TOE
counters the threats by the following functions: User Authentication, Hard Disk Data
Overwrite, and Internal Network Data Protection.
CRP-C0590-01
11
The User Authentication function of the TOE is to allow only identified and
authenticated users to use the TOE. When successfully identified and authenticated
users attempt to use MFD's basic functions such as copy, print, network scan, and fax,
the TOE checks the identification information of authorized users set for each basic
function of the MFD and allows only authorized users to use them. In addition, when
users who are permitted to use the basic functions of the MFD attempt to manipulate
user data, the TOE allows only users with access rights to access the data.
The Hard Disk Data Overwrite function of the TOE is to overwrite the internal HDD
area where the document data are stored when the data are deleted. This function
prevents the residual information of the deleted document data from being read out.
The Internal Network Data Protection function of the TOE is to use encryption
communication protocol and to encrypt the communication data when the TOE
communicates with client PCs and various servers.
With the above functions, the TOE prevents the user data to be protected from being
disclosed or altered by unauthorized usage of the TOE or by unauthorized access to the
communication data.
2) Countermeasures against threat "T.PROT.ALT," "T.CONF.DIS," and "T.CONF.ALT"
These are the threats to the data used for security functions. The TOE counters the
threats by the following functions: User Authentication, System Administrator's Security
Management, Customer Engineer Operation Restriction, and Internal Network Data
Protection.
The User Authentication function and the System Administrator's Security Management
function of the TOE are to allow only identified and authenticated system administrators
to refer to and change the data used for security functions. For general users, changing
their own passwords is permitted.
The Customer Engineer Operation Restriction function of the TOE is to allow only
identified and authenticated system administrators to refer to and change the setting
data that control enabling and disabling of customer engineer operation restriction.
The Internal Network Data Protection function of the TOE is to use encryption
communication protocol and to encrypt the communication data when the TOE
communicates with client PCs and various servers.
With the above functions, the TOE prevents the data to be protected from being disclosed
or altered by unauthorized usage of the TOE or by unauthorized access to the
communication data.
3.1.2 Organizational Security Policies and Security Function Policies
3.1.2.1 Organizational Security Policies
Organizational security policies required in use of the TOE are shown in Table 3-2. These
organizational security policies are the same as those described in the PP, except that
P.CIPHER is added.
CRP-C0590-01
12
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
.CIPHER To prevent unauthorized reading-out, the document data
in the internal HDD will be encrypted by the TOE.
(A cryptographic key does not need to be destructed.)
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. Details of each security function are shown in Chapter 5.
1) Means of organizational security policy "P.USER.AUTHORIZATION"
The TOE realizes this policy by the User Authentication function.
The User Authentication function of the TOE is to allow only identified and
authenticated users to use the TOE. When successfully identified and authenticated
users attempt to use MFD's basic functions such as copy, print, network scan, and fax,
the TOE checks the identification information of authorized users set for each basic
function of the MFD and allows only authorized users to use them.
2) Means of organizational security policy "P.SOFTWARE.VERIFICATION"
The TOE realizes this policy by the Self Test function.
The Self Test function of the TOE is to verify check sum of Controller ROM and FAX
ROM upon booting. The TOE also checks the TSF data stored in NVRAM and SEEPROM
to detect errors. Thus, this function verifies the integrity of TSF executable code.
3) Means of organizational security policy "P.AUDIT.LOGGING"
The TOE realizes this policy by the Security Audit Log function.
CRP-C0590-01
13
The Security Audit Log function of the TOE is to record security relevant events as audit
logs. Only identified and authenticated system administrators can read out the stored
audit logs. It is not possible to delete and modify the audit logs.
4) Means of organizational security policy "P.INTERFACE.MANAGEMENT"
The TOE realizes this policy by the User Authentication and the Information Flow
Security functions.
The User Authentication function of the TOE is to allow only identified and
authenticated users to use the TOE. Furthermore, the TOE terminates a session when
the state that a user does not perform any operations continues for the specified amount
of time.
With the Information Flow Security function of the TOE, the data received from various
external interfaces of the TOE cannot be transferred to the internal network unless the
data are processed by the TOE, thereby preventing unauthorized data transfer from
external interfaces (including telephone lines) to the internal network.
5) Means of organizational security policy "P.CIPHER"
The TOE realizes this policy by the Hard Disk Data Encryption function.
The Hard Disk Data Encryption function of the TOE is to encrypt data to be written to
the internal HDD. The cryptographic algorithm is 256-bit AES.

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 those
described in the PP. 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 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.
A.ADMIN.TRUST Administrators do not use their privileged access rights
for malicious purposes.
4.2 Environmental Assumptions
The TOE is assumed to be used at general office, connected to the internal network, and
used from client PCs connected to the internal network. Figure 4-1 shows the general
operational environment of the TOE.
It is possible to use the print function of the TOE by connecting client PCs to the TOE via
USB ports
CRP-C0590-01
15
Figure 4-1 Operational Environment of the TOE
The following are components excluding the TOE in the operational environment of the
TOE:
1) General User Client
General User Client is a general-purpose PC for general users and connected to the TOE
via USB or the internal network. The following software is required:
- OS: Windows 7 or Windows 8.1
- Printer driver
When the client is connected to the internal network, the following software is required
in addition to those listed above:
- Web browser (included with OS)
2) System Administrator Client
System Administrator Client is a general-purpose PC for system administrators and
connected to the TOE via the internal network. The following software is required:
CRP-C0590-01
16
- OS: Windows 7 or Windows 8.1
- Web browser (included with OS)
3) LDAP Server, Kerberos Server
When Remote Authentication is set for the user authentication function on the TOE,
authentication server of either LDAP server or Kerberos server is necessary. When Local
Authentication is set, neither authentication server is necessary.
LDAP server is also used to acquire user attributes to identify SA role when Remote
Authentication is used. Thus, even for the authentication with Kerberos server, LDAP
server is necessary to use the SA role.
In this evaluation, the following software is used as LDAP server and Kerberos server.
- Windows Active Directory
4) Mail Server, FTP Server
The TOE has basic functions to transfer document data with Mail server and FTP server.
These servers are necessary upon using the basic MFD functions.
5) DNS Server
The TOE uses the DNS server to retrieve IP addresses of various servers, etc.
It should be noted that the reliability of the hardware and the cooperating software other
than the TOE shown in this configuration is out of scope in the evaluation. Those are
assumed to be trustworthy.
4.3 Clarification of Scope
As described below, there are restrictions on the security functions of the TOE.
1) Restrictions for Remote Authentication
The TOE function that restricts the number of characters of password to be nine or more
is not applied to user password stored in the Remote Authentication server (LDAP server
or Kerberos server). A system administrator is responsible for ensuring that user password
stored in the remote authentication server is long enough not to be predicted.
2) IPsec for IPv6
The TOE was evaluated with only IPsec protocol for IPv4. The TOE was not evaluated
with IPsec for IPv6, so the operation with IPsec for IPv6 is not assured by this
evaluation.
CRP-C0590-01

5. Architectural Information
This chapter explains the scope and the main components (subsystem) of the TOE.
5.1 TOE Boundary and Components
Figure 5-1 shows the components of the TOE. The scope of the TOE is the MFD including
the Fax board.
Figure 5.1 Components of the TOE
The TOE has security functions and other basic MFD functions. The following describe the
security functions of the TOE. Regarding the basic MFD functions, please refer to Glossary
in Chapter 11.
1) User Authentication
This function includes the following three functions: identification and authentication of
users, access control for MFD's basic functions, and access control for user data.
CRP-C0590-01
18
a) Identification and authentication of users
This is the function to identify and authenticate TOE users with their IDs and
passwords. Identification and authentication are applied to the following user
interfaces.
- Control panel
- Client PCs (Web browsers)
For the print data sent from Client PCs (printer drivers), only the identification of a
user ID is performed, and the authentication using a password is not performed.
The following types of authentication are available: "Local Authentication" that uses
user IDs and passwords stored in the TOE, and "Remote Authentication" that uses
LDAP servers and Kerberos servers outside the TOE.
For enhanced security, the following are provided for the user identification and
authentication.
- For Local Authentication, users are required to use passwords of nine or more
characters.
- For Local Authentication, if a system administrator fails to be authenticated for five
times in a row, the authentication process is suspended. This restriction is not
applied to general users.
- If no user operation is confirmed for a specified amount of time after a user has been
successfully authenticated, the session is terminated.
b) Access control for MFD's basic functions
This is the function to restrict the use of the MFD's basic functions such as copy,
network scan, print, and fax.
When a user attempts to use a MFD's basic function, the TOE refers to the user
permission set for each user role and determines whether to restrict or allow the use of
the basic functions. However, general users are not allowed to use the Faxbox function.
c) Access control for user data
This is the function to restrict the access to document data and job information used in
MFD's basic functions to only authorized users.
As to the document data stored in the Store Print or job information, only the user who
is verified to be the owner of the data can perform operations on the document data or
job information. As to the document data stored in the Faxbox, only system
administrators are allowed to perform operations on the data.
As to the document data generated in the process of the fax send function or network
scan function, only those users who performed the functions are allowed to send the
data by fax or via network. No access means to such data is provided to other users.
2) System Administrator's Security Management
This is the function that permits only identified and authenticated system
administrators to configure, refer to, and change the setting of the data used for security
functions. For general users, changing their own passwords is permitted.
CRP-C0590-01
19
3) Customer Engineer Operation Restriction
This is the function with which system administrators restrict the operation by customer
engineers. Only identified and authenticated system administrators are permitted to
refer to and change the setting data that control enabling and disabling of customer
engineer operation restriction. If customer engineer operation is restricted, customer
engineers are required to enter the password set by a system administrator in order to
operate the MFD.
4) Security Audit Log
This is the function that records security relevant audit events as audit logs. Only
identified and authenticated system administrators can read out the audit logs stored in
the TOE via Web browsers. It is not possible to delete or modify the audit logs.
Up to 15,000 events can be stored as audit logs. When the number of events exceeds the
limit, the oldest event is deleted to record a new event.
5) Hard Disk Data Encryption
This is the function that encrypts data to be stored in the internal HDD. The
cryptographic algorithm is 256-bit AES. A cryptographic key is created using the
SHA-256 algorithm based on values generated randomly by the TOE. A cryptographic
key is automatically created when power of the TOE is turned on for the first time in the
factory. The cryptographic key cannot be deleted or changed.
6) Hard Disk Data Overwrite
This is the function that overwrites the internal HDD area where document data were
stored when the data are deleted. This overwrite operation is performed in the following
cases.
- When document data have become unnecessary after a user finishes using MFD's
basic functions. Unnecessary data include those temporarily generated in the TOE
while the TOE is executing some processing.
- When a user has requested to delete document data.
- When the power of the MFD is turned on. If the overwrite operation has not been
completed when the power is turned off, the operation resumes when the power is
turned on.
- When "On Demand Overwrite function" is executed; the function deletes the stored
data at the specified time according to the setting by a system administrator.
The three pass overwrite pattern (overwriting with zero, one, and a random number) is
used. It should be noted that the data actually overwritten on the internal HDD are
encrypted. Therefore, the data actually overwritten is different from the overwrite
pattern.
7) Internal Network Data Protection
This is the function that encrypts communication with IT devices using the following
protocols and methods.
- IPsec, TLS (v1.0, v1.1, v1.2), S/MIME
CRP-C0590-01
20
8) Information Flow Security
This is the function that prevents unauthorized data transfer from external interfaces
(including telephone lines) to the internal network. Data received from external
interfaces of the TOE cannot be transferred to the internal network unless the data are
processed by the TOE.
9) Self Test
This is the function that conducts the following self tests when the TOE is turned on.
- Verification of the check sum of Controller ROM and FAX ROM
- Verification of TSF data stored in NVRAM and SEEPROM
5.2 IT Environment
When user authentication by Remote Authentication is enabled, the TOE uses an external
authentication server (LDAP server or Kerberos server) to identify and authenticate users.
The TOE also checks whether a user has the SA role or not by using LDAP server, in case of
Remote Authentication.
CRP-C0590-01

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>
(1) The behavior that can be observed at the external interface of the TOE
Operate basic MFD functions and security management functions from the MFD
control panel, system administrator client, and general user client, and confirm the
response, MFD behavior, communication data, and audit log.
(2) The behavior that cannot be observed at the external interface of the TOE
The following approaches were employed to confirm the behavior that cannot be
observed at the external interface of the TOE:
- Check the internal behaviors of the TOE using the developer interfaces.
- Check the behavior of modules such as an encryption function using the firmware
modified for the developer testing.
- Confirm that the encryption algorithm is implemented as specified by comparing
the data that were obtained by the above approach and the known data calculated by
a different approach.

parameters are operated as specified. Regarding the user authentication function, it was
confirmed that each case of local authentication, remote authentication (LDAP server),
and remote authentication (Kerberos server), behaves as specified according to the user
role.
The variations of the input parameters include the rewrite of communication data
between web browsers and the TOE, and power-on/off of the TOE while document data is
overwritten.

The developer testing was performed on 78 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
CRP-C0590-01
27
The evaluator confirmed an approach of the performed developer testing and the
legitimacy 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 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 sampling testing to reconfirm the execution of security
functions by 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 ensure that security functions are certainly implemented from 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 is the same as
that of the developer testing shown in Figure 7-1, except for the following.
- As the TOE, only Xerox VersaLink B7025 and Xerox VersaLink B7035 were used.
- As a fax destination, Xerox VersaLink C405, which is an MFD, was used instead of
general user client 2.
The evaluator judged that testing on 2 representative models is sufficient, since other
models differ only in print speeds according to the model number.
The evaluator determined that changing the fax destination does not affect the security
functions of the TOE.
The independent testing was performed in the same environment as the TOE configuration
identified in the ST.
The testing tools and components in the independent testing environment were the same
as those used in the developer testing and some of them include tools and components
developed by the developer. The validity verification and operation tests for the testing
tools and components were performed by the evaluator.
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 that the evaluator designed from the developer
testing and the provided evaluation evidential materials are shown below.
<Viewpoints of the Independent Testing>
