including the operation control processing and the image data management triggered by the
panel of the main body of MFP or through the network.
The TOE supports the protection against the exposure of the highly confidential documents
stored in MFP. Moreover, for the danger of illegally bringing out HDD, which stores image data
in MFP, TOE can encrypt all the data written in HDD including image data using ASIC
(Application Specific Integrated Circuit). Besides, the TOE has the function that deletes all the
data of HDD completely by deletion method compliant with various overwrite deletion standards
at the time of abandonment or the lease returns and the function that controls the access from
the public line against the danger using Fax function as a steppingstone to access internal
network. So it contributes to the prevention of information leakage of the organization that uses
MFP.
1.4. TOE Description
1.4.1. Roles of TOE Users
The roles of the personnel related to the use of MFP with TOE are defined as follows.
User
An MFP user who is registered into MFP. (In general, the employee in the office is assumed.)
Administrator
An MFP user who manages the operations of MFP. Manages MFP’s mechanical operations
and users. (In general, it is assumed that the person elected from the employees in the office
plays this role.)
Service engineer
A user who manages the maintenance of MFP. Performs the repair and adjustment of MFP. (In
general, the person-in-charge of the sales companies that performs the maintenance service of
MFP in cooperation with Konica Minolta Business Technologies, Inc. is assumed.)
Responsible person of the organization that uses MFP
A responsible person of the organization that manages the office where the MFP is installed.
Assigns an administrator who manages the operation of MFP.
Responsible person of the organization that manages the maintenance of MFP
A responsible person of the organization that manages the maintenance of MFP. Assigns
service engineers who manage the maintenance of MFP.
Besides this, though not a user of TOE, those who go in and out the office are assumed as
accessible persons to TOE.

MFP’s use environments
environments
An intra-office LAN exists as a network in the office.
MFP is connected to the client PCs via the intra-office LAN, and has mutual data
communications.
When a SMTP, FTP, or WebDAV server is connected to the intra-office LAN, MFP can carry
out data communications with these servers, too. (The DNS service will be necessary when
setting a domain name of the SMTP/FTP/WebDAV server.)
It is also assumed to unify management of user IDs/passwords in a server. In this case, TOE
can control access to the MFP by using the user registration information in the user
information management server.
When the intra-office LAN connects to an external network, measures such as connecting via
a firewall are taken, and an appropriate setup to block access requests to the MFP from the
external network is applied.
The intra-office LAN provides a network environment that cannot be intercepted by office
operations including using switching hubs and installing wiretapping detectors.
The public line connected with MFP is used for communications by Fax and the remote
diagnostic function.

1.4.3. Logical Scope of TOE
Users use a variety of functions of TOE from the panel and a client PC via the network.
Hereafter, this section explains typical functions such as the basic function, the user box function
to manage the image files stored, the user identification and authentication function, the
administrator function manipulated by administrators, the service engineer function
manipulated by service engineers, and the function operated in the background without user's
awareness.
1.4.3.1. Basic Function
In MFP, a series of functions for the office work concerning the image such as copy, print, scan,
and fax exists as basic functions, and TOE performs the core control in the operation of these
functions. It converts the raw data acquired from the external device of the MFP controller into
image files, and stores them in RAM and HDD. (For print image files from client PCs, multiple
types of conversion are applied.) These image files are converted into data to be printed or sent,
and transmitted to the device outside of the MFP controller concerned.
Operations of copy, print, scan, and FAX are managed by the unit of job, so that operation
priority can be changed, finishing of print jobs can be changed, and such operations can be
aborted, by giving directions from the panel.
The following is the functions related to the security in the basic function.
Secure Print Function
When a Secure Print password is received together with printing data, the image file is
stored as standby status. Then, printing is performed by a print direction and password entry
from the panel.
When printing is requested by a client PC, this function eliminates the possibility that other
users stole a glance at the printing of highly confidential data, or such data is slipped into the
other printings.
ID & Print Function
When this function is set up, usual print data are saved in the print waiting state, and
printed by the user authentication processing from the panel. Even when this function is not
set up, if it is specified on the print data to activate this function, the system will operate in
the same manner as this function is set up by a user.
1.4.3.2. User Box Function

Security Target
A directory called a "user box" can be created as an area to store image files in HDD. Three
types of user box are usable; the first is the personal user box which a user possesses, the second
is the public user box which is shared by registered users who made a certain number of groups,
and the third is the group user box which is shared by the users belonging to same account. As
for the personal user box, the operation is limited only for the user who owns it, the public user
box performs access control by sharing a password set to the user box among users. And the
group user box limits operations only for the users of the account that are permitted to use it.
TOE processes the following operation requests to a user box or image files in the user box that
is transmitted from the panel or the network unit through a network from a client PC.
Print, transmit, and download from a client PC, of image files in a user box
The encryption of user box file is possible in the E-mail that is one of the transmission
methods.
Delete an image file in a user box, move/copy it to other user boxes and copy it to external
memory
Set a storing period of image files in a user box (delete automatically after the period passes.)
Change the name and password of a user box, or delete a user box
Set attributes of a user box (change the type of a personal user box, public user box, or group
user box)
1.4.3.3. User Authentication Function
TOE can limit the user who uses MFP. For access through the panel or the network, TOE
identifies and authenticates that the user is permitted to use the MFP by applying the user
password and user ID. When the identification and authentication succeeds, TOE permits the
user the use of the basic function and the user box function, etc.
Several types of user authentication like below are supported.
(1) Machine authentication2
A method to authenticate user at MFP by registering a user ID and a user password into
HDD on the MFP controller.
(2) External server authentication
A method to authenticate user at MFP by using the user ID and the user password that are
registered on the user information management server which is connected with the
intra-office LAN without managing the user ID and user password on the MFP side.
Though multiple methods called Active Directory3, NTLM4, and NDS are supported, the
method of the external server authentication assumed in this ST is applied only to the case
of using Active Directory.
1.4.3.4. Account Authentication Function5
2
When user is set “Pause” by administrator function, authentication function for the user does not work.
A method of directory service that Windows Server 2000 (or later) supports to uniformly manage user
information in the network environment of Windows platform.
4 An abbreviation of NT LAN Manager. An authentication method used in directory service that Windows NT
supports to uniformly manage user information in network environment of Windows platform.

Security Target
TOE provides the functions that run background without awareness of the user and the
updating function of TOE. The following explains the major functions.
Encryption key generation function
Performs encryption/decryption by ASIC when writing data in HDD or reading data from
HDD. (TOE does not process the encryption and description itself.)
The operational setup of this function is performed by the administrator function. When
activated, TOE generates the encryption key by the encryption passphrase that was entered
on the panel.
Remote diagnostic function
MFP’s equipment information such as operating state and the number of printed sheets is
managed by making use of the connection by a port of FAX public line, by a modem through
RS-232C or by E-mail or WebDAV to communicate with the support center of MFP produced
by Konica Minolta Business Technologies, Inc. In addition, if necessary, appropriate services
(shipment of additional toner packages, account claim, dispatch of service engineers due to
the failure diagnosis, etc.) are provided.
Updating function of TOE
TOE facilitated with the function to update itself. As for the update means, there are a
method that exists as one of items of remote diagnostic function, a method that downloads
from FTP server through Ethernet (TOE update function via Internet), and a method that
performs the connection of external memory.
Encryption communication function
TOE can encrypt the data transmitted from client PC to MFP, and the data received by
download from MFP by using SSL/TLS.
The operational setup of this function is performed by the administrator function.
S/MIME certificate automatic registration function
It is the function to register the certificate for S/MIME (conforms to ITU-T X.509) with each
transmission address automatically. When a certificate is attached in received e-mail, MFP
recognizes user ID according to the information of e-mail header, and registers the
certificate as certificate of the same user ID.
The standard is that MFP is not installed Fax unit and does not have a port of Fax public line,
so there is not the access to the internal network through MFP. TOE provides the following
function, provided that Fax unit is installed in MFP.
Fax unit control function
TOE prohibits access to the internal network, where MFP was connected to, from a port of
Fax public line through Fax unit.
TOE makes effective use of the security function (HDD encryption function) of ASIC, which is
an external entity. The following explains typical functions related to the external entity.

Security Target
Utilization of ASIC
ASIC, an external entity, activates a function to encrypt the data in HDD as a function to
protect unauthorized bring-out of data and so on when an encryption passphrase is set up.
1.4.3.8. Enhanced Security Function
Various setting functions related to the behavior of the security function for the Administrator
function and the Service engineer function can be set collectively to the secure values by the
operation settings of the "Enhanced Security Function". Each value set is prohibited changing
itself into the vulnerable one individually. As the function that does not have a setting function of
the operation individually, there is the reset function of the network setting and the update
function of TOE through the network, but the use of these functions is prohibited.
The following explains the series of the setting condition of being the enhanced security
function active. In order to activate the enhanced security function, the prerequisite is required
that an administrator password and a CE password should be set along with the password

3. Security Problem Definition
This chapter will describe the concept of protected assets, assumptions, threats, and
organizational security policies.
3.1. Protected Assets
Security concept of TOE is "the protection of data that can be disclosed against the intention of
the user". As MFP is generally used, the following image file in available situation becomes the
protected assets.
•
Secure Print file
An image file registered by Secure Print.
•
ID & print file
An image file saved as an ID & print file when print data are registered by the ID & print
function.
•
User Box file
An image file stored in the personal user box, public user box and group user box.
As for a image file of a job kept as a wait state by activities of plural jobs, and a image file of a
job kept that prints the remainder of copies becoming as a wait state for confirmation of the
finish, and other than the image file dealt with the above-mentioned is not intended to be
protected in the general use of MFP, so that it is not treated as the protected assets.
In the store of a secure print file or an ID & print file and the transmission of a user box file,
making in the preparation for the threat thought when unauthorized MFP or mail server is
connected by any chance, or when operational setup of PC-FAX is changed even if without
unauthorized MFP, the setting of MFP (IP address etc.) and operation setting of PC-FAX require
not to be modified illegally. Therefore, the setting of MFP (IP address etc.) and operation setting
of PC-FAX are considered as subsidiary protected assets.
On the other hand, when the stored data have physically gone away from the jurisdiction of a
user, such as the use of MFP ended by the lease return or discard, or the case of a theft of HDD,
the user has concerns about leak possibility of every remaining data. Therefore, in this case, the
following data files become protected assets.
•
Secure Print File
•
ID & print File
•
User Box File
•
On-memory Image File
Image file of job in the wait state
•
Stored Image File
•
HDD remaining Image File
Stored image files other than secure print file, user box file, or ID & print file
The file which remains in the HDD data area that is not deleted only by general
deletion operation (deletion of a file maintenance area)

3.4. Organizational Security Policies
Recently, there are a lot of organizations that demand security of network in office. Although a
threat of wiretapping activities etc. in intra-office LAN is not assumed in this ST, TOE security
environment that corresponds to the organization that demanded security measures in
intra-office LAN is assumed. Moreover, although a accumulated data in a client PC and a server
existing in internal network, and a general data traveling across the internal network are not
protected assets, TOE security environment that corresponds to the organization that prohibited
the access to internal network via MFP from Fax public line portal is assumed.
The security policies applied in the organization that uses TOE are identified and described as
follows.
P.COMMUNICATION
P.COMMUNICATIONNICATION-DATA (Secure communication of image file)
Highly confidential image files (secure print files, user box files, and ID & print files) which are
transmitted or received between IT equipment must be communicated via a trusted pass to the
correct destination, or encrypted when the organization or the user expects to be protected.
P.REJECT
P.REJECTREJECT-LINE (Access
(Access prohibition from public line)
line)
An access to internal network from public line via the Fax public line port must be prohibited.

4.3.2. Sufficiency of Assumptions
The security objectives for the assumptions are described as follows.
A.ADMIN (Personnel
(Personnel Conditions to be an Administrator)
This condition assumes that administrators are not malicious.
With OE.ADMIN, the organization that uses the MFP assigns personnel who are reliable in
the organization that uses the MFP, so the reliability of the administrator is realized.
A.SERVICE (Personnel Conditions to be a Service Engineer)
This condition assumes the service engineer are not malicious.
With OE.SERVICE, the organization that manages the maintenance of the MFP educates the
service engineer. Also the administrator needs to observe the maintenance of the MFP, so that
the reliability of service engineers is assured.
A.NETWORK (Network Connection
Connection Conditions for the MFP)
MFP)
This condition assumes that there are no wiretapping activities and no access by an
unspecified person from an external network to the intra-office LAN.
OE.NETWORK regulates the wiretapping prevention by the installation of devices such as a
wiretapping detection device and device to perform the encryption communication on the
intra-office LAN. It also regulates the unauthorized access prevention from external by the
installation of devices such as firewall in order to block access to the MFP from the external
networks, so that this condition is realized.
A.SECRET (Operating condition concerning confidential information)
This condition assumes each password and encryption passphrase using for the use of TOE
should not be leaked by each user.
OE.SECRET regulates that the administrator makes the user to execute the operation rule
concerning the secure print password, user box password, user password, and account
password and that the administrator executes the operation rule concerning the
administrator password, SNMP password, encryption passphrase, account password, and
WebDAV server password. It also regulates that the service engineer executes the operation
rule concerning the CE password, and that the service engineer makes the administrator to
execute the operation rule concerning the administrator password, so that this condition is
realized.
A.SETTING (Enhanced Security Function Operational Setup Condition)
Condition)
This condition assumes the enhanced security function operational settings condition is
satisfied.
OE.SETTING-SECURITY regulates that this is used after the administrator activates the
enhanced security function, so that this condition is realized.
4.3.3. Sufficiency of Threats
The security objectives against threats are described as follows.

Security Target
T.DISCARDT.DISCARD-MFP (Lease return and discard of MFP)
This threat assumes the possibility of leaking information from MFP collected from the user.
O.OVERWRITE-ALL is that TOE provides the function to overwrite data for the deletion of
all area of HDD and initializes the information of NVRAM, so that the possibility of the
threat is removed by executing this function before MFP is collected.
Accordingly, this threat is countered sufficiently.
T.BRINGT.BRING-OUTOUT-STORAGE (Unauthorized bringing
bringing out HDD)
HDD)
This threat assumes the possibility that the image data in HDD leaks by being stolen from
the operational environment under MFP used or by installing the unauthorized HDD and
taking away with the data accumulated in it.
For the above, the possibility of the threat is reduced because O.CRYPTO-KEY assumes that
TOE generates an encryption key to encrypt the data written in the HDD, and a mechanical
operation

ASIC
is
supported
by
O.CRYPTO-CAPABILITY.
Accordingly, this threat is countered sufficiently.
T.ACCESST.ACCESS-PRIVATEPRIVATE-BOX (Unauthorized access to personal user box using user function)
function)
This threat assumes the possibility that an unauthorized operation is done by using the user
function for the personal user box which each user uses to store the image file.
O.REGISTERED-USER is assumed that only the user to whom TOE succeed identification
and authentication is permitted to use MFP installed TOE, furthermore, the operation of a
personal user box and the user box file in a personal user box is restricted only to the user
who is the owner by O.PRIVATE-BOX, so that the possibility of the threat is reduced. When
the external user information management server is used, the possibility of the threat is
reduced
because
the
user
identification
and
authentication
is
operated
through
O.AUTH-CAPABILITY supporting the operation for the user authentication function by the
user information management server of Active Directory and through OE.SERVER setting to
use the user management by Active Directory by the administrator.
OE.FEED-BACK uses the application regulating to return the protected feedback for the
entered password in the user's authentication, and OE.SESSION also requires the log-off
operation after the operation ends, so that O.REGISTERED-USER and O.PRIVATE-BOX are
supported sufficiently.
Accordingly, this threat is countered sufficiently.
T.ACCESST.ACCESS-PUBLICPUBLIC-BOX (Unauthorized access to public user box using user function)
function)
This threat assumes the possibility that an unauthorized operation is done by using the user
function for the public user box which each user shares to store the image file.
O.REGISTERED-USER assumes that only the user to whom TOE succeed identification and
authentication is permitted to use MFP installing TOE, furthermore, the operation of the
public user box and the user box file in the public user box is restricted only to the user who is
permitted by O.PUBLIC-BOX, so that the possibility of the threat is reduced. When the
external user information management server is used, the possibility of the threat is reduced
because
the

user information management server of Active Directory and through OE.SERVER setting to
use the user management by Active Directory by the administrator.
OE.FEED-BACK uses the application regulating to return the protected feedback for the
entered password in the user's authentication and user box's authentication, and
OE.SESSION
requires
the
log-off
operation
after
the
operation
ends,
so
that
O.REGISTERED-USER and O.PUBLIC-BOX are supported sufficiently.
Accordingly, this threat is countered sufficiently.
T.ACCESST.ACCESS-GROUPGROUP-BOX (Unauthorized access to a group user box using user function)
This threat assumes the possibility that an unauthorized operation is performed by using the
user function for the group user box that is a storage area of image file used by user who is
permitted the use of the account, or the user box file in it.
O.REGISTERED-USER assumes that TOE permits only the user who succeeded the
identification and authentication to use MFP installed TOE, furthermore, the operation of
the group user box and user box file in the group user box is restricted only to the permitted
user by O.GROUP-BOX, so that the possibility of the threat is removed. When the external
user information management server is used, the possibility of the threat is reduced because
the user identification and authentication is operated through O.AUTH-CAPABILITY
supporting the operation for the user authentication function by the user information
management server of Active Directory and through OE.SERVER setting to use the user
management by Active Directory by the administrator.
OE.FEED-BACK uses the application regulating to return the protected feedback for the
entered password in the user's authentication and account's authentication, and
OE.SESSION also requires the log-off operation after the operation ends, so that
O.REGISTERED-USER and O.GROUP-BOX are supported sufficiently.
Accordingly, this threat is countered sufficiently.
T.ACCESST.ACCESS-SECURESECURE-PRINT (Unauthorized access
access to a secure print file or an ID & print file
using the user function)
function)
This threat assumes the possibility that an unauthorized operation is done to the secure print
and ID & print using user function.
O.REGISTERED-USER assumes that TOE permits only the user who succeeded the
identification and authentication to use MFP installing TOE, furthermore, the operations of
the secure print and ID & print are limited only to the authorized user by O.SECURE-PRINT,
so that the possibility of the threat is reduced. When the external user information
management server is used, the possibility of the threat is reduced because the user
identification and authentication is operated through O.AUTH-CAPABILITY supporting the
operation for the user authentication function by the user information management server of
Active Directory and through OE.SERVER setting to use the user management by Active
Directory by the administrator.
OE.FEED-BACK uses the application regulating to return the protected feedback for the
entered password in the user's authentication and access authentication to the secure print,
and OE.SESSION requires the log-off operation after the operation ends, so that
O.REGISTERED-USER and O.SECURE-PRINT are supported sufficiently.
Accordingly, this threat is countered sufficiently.

Security Target
T.UNEXPECTED
T.UNEXPECTEDUNEXPECTED-TRANSMISSION (Transmission
(Transmission to unintended address)
address)
This threat assumes the possibility of sending the user box file to the address that isn't
intended, when the network setting that relates to the transmission is illegally changed. This
is concerned about a possibility that the user box file is transmitted to the specified server
illegally without the change of the network environment constitution by the malicious person
by, for instance, illegally being changed the address of the SMTP server that relays E-mail for
the E-mail, or illegally being changed the address of the DNS server where the domain name
is inquired when the address of the SMTP server is used for a search of the domain name.
For FTP transmission, by being likely to use the mechanism of the search of the domain name
is concerned about the similar possibility of the incident might be occurred by E-mailing.
Furthermore, when the network setting which is related to the address of MFP is modified
illegally, it assumes the possibility to use the print function to the unauthorized entity from
client PC by the user who believes as TOE. Especially, it becomes a problem if a secure print
file or an ID & print file which is required to be concealed from other users in the office is
transmitted to the unauthorized entity.
In addition to this, the setting of PC-FAX reception and the setting of TSI reception assumes
the possibility of unintended user box file storing at FAX reception.
On the other hand, O.CONFIG regulates that the role to operate the network setting relating
to the transmission of TOE, the setting of PC-FAX reception and the setting of TSI reception
are limited to the administrator, and so the possibility of this threat is removed.
OE.FEED-BACK uses the application regulating that the feedback protected is returned for
the entered password by the administrator's authentication and OE.SESSION requires to
logoff after the operation ends, so that O.CONFIG is supported sufficiently.
Accordingly, this threat is countered sufficiently.
T.ACCESST.ACCESS-SETTING (Unauthorized change of function setting condition related
related to security)
security)
This threat assumes the possibility of developing consequentially into the leakage of the user
box files, secure print files, or ID & print files by having been changed the specific function
setting which relates to security.
O.CONFIG regulates that only the administrator and the service engineer are permitted to
perform the setup of the enhanced security function that controls all setting function related
to a series of security, and so the possibility of the threat is removed.
OE.FEED-BACK uses the application regulating that the feedback protected is returned for
the entered various passwords by the administrator's authentication, and OE.SESSION is
also requested to logoff respectively after the operations of the administrator mode ends, so
that O.CONFIG is supported sufficiently.
Accordingly, this threat is countered sufficiently.
T.BACKUPT.BACKUP-RESTORE (Unauthorized use of backback-up function and restoration
restoration function)
function)
This threat assumes a possibility that user box files, secure print files, or ID & print files may
leak when the back-up function or the restoration function is illegally used. Moreover, this
assumes that confidential data such as passwords might leak or various settings are falsified,
so that user box files, secure print files, or ID & print files may leak.
O.CONFIG regulates that the use of the back-up function and the restoration function is
permitted only to the administrator, so that the possibility of the threat is removed.
OE.FEED-BACK uses the application regulating that the protected feedback is returned for

Accordingly, this threat is countered sufficiently.
4.3.4. Sufficiency of Organizational Security Policies
Security objective corresponding to organizational security policies is explained as follows.
P.COMMUNICATIONP.COMMUNICATION-DATA (secure communication of image file)
This organizational security policy prescribes carrying out processing via trusted pass to a
correct destination or encrypting to ensure the confidentiality about the image file which
flows on a network in the case of the organization or the user expect to be protected. As this
corresponds as one's request, there is no need to provide secure communication function for
all communication. At least one secure communication method between MFP and client PC
needs to be provided when transmitting the secure print file or the user box file.
O.TRUSTED-PASS provides Trusted Channel to a correct destination in the transmission
and reception of an image between MFP and client PCs for user box files, secure print files,
and ID & print files that save confidential images, so that the organizational security policies
is achieved.
Also, the security objective provides the transmission function to a correct destination by
encrypting the user box file transmitted by e-mail from MFP to client PC by
O.CRYPTO-MAIL, so that the organizational security policies is achieved.
Furthermore, O.CONFIG restricts the Trusted Channel function setting data, the
management of the user box files' encryption by e-mail and the transmission address data to
the administrator. And, OE.FEED-BACK uses the application regulating that the protected
feedback is returned for the entered password in the administrator's authentication, and
OE.SESSION is also regulated to log off after the operations of the administrator mode ends,
so that O.CONFIG is supported.
Accordingly, this organizational security policy is sufficiently to achieve.
P.REJECT
P.REJECTCT-LINE (Access
(Access prohibition from public line)
This organizational security policy prohibits being accessed to a stored data in a client PC
and a server existing in internal network or a general data flowing on internal network from
public line via the port of Fax public line on Fax unit installed to MFP.
This means that communication, like remote diagnostic function or illegal operation
command, except image data which is sent from public line network and forwarded to
internal network via the port of Fax public line of MFP is not forwarded to internal network,
even though Fax unit is installed on MFP at the request of the organization.
O.FAX-CONTROL prohibits the access to the data existing in internal network including a
general data from public line via the Fax public line portal.
Also, OE.FAX-UNIT is regulated to install Fax unit which is the optional part on MFP by
service engineer, so that O.FAX-CONTROL is supported.
Accordingly, this organizational security policy is achieved.

5. Extended Components Definition
5.1. Extended Function Component
In this ST, three extended function components are defined. The necessity of each security
function requirement and the reason of the labeling definition are described.
FAD_RIP.1
This is the security function requirement for the protection of the remaining information of
user data and TSF data.
Necessity of extension
The regulation for the protection of the TSF data remaining information is necessary. But
the security function requirement to explain the protection of the remaining information
exists only in FDP_RIP.1 for the user data. There is no security function requirement to
satisfy this requirement.
Reason for applied class (FAD)
There is no requirement to explain both of the user data and the TSF data with no
distinction. Therefore, new Class was defined.
Reason for applied family (RIP)
As this is the extension up to the TSF data by using the content explained by the relevant
family of FDP class, the same label of this family was applied.
FIT_CAP.1
This is the security function requirement for regulating the necessary ability for TOE to use
effectively the security function of the external entity, IT environment.
Necessity of extension
In case of TOE using the external security functions, the external security function to be
surely secure is important, but TOE ability to provide is very important in order to use
correctly the external security function. But there is no concept as this requirement in the
security function requirements.
Reason for applied class (FIT)
There is no such concept in CC part 2. Therefore, new Class was defined.
Reason for applied family (CAP.1)
As similar to class, there is no such concept in CC part 2. Therefore, new Family was
defined.
5.1.1. FAD_RIP.1 Definition
Class name
FAD: Protection of all data
Meaning of abbreviation: FAD (Functional requirement for All Data protection)
Class behavior
This class contains a family specifying the requirement related with the protection of the user
data and the TSF data with no distinction. One family exists here.

6. IT Security Requirements
In this chapter, the TOE security requirements are described.
<Definition of Label>
Label>
The security function requirements required for the TOE are described. Those regulated in CC
Part 2 will be directly used for the functional requirements components, and the same labels will
be used as well. The new additional requirement which is not described in CC part 2 is newly
established and identified with the label that doesn't compete with CC part 2.
< Method of specifying security function requirement "Operation"
Operation" >
In the following description, when items are indicated in "italic" and "bold," it means that they
are assigned or selected. When items are indicated in "italic" and "bold" with parenthesis right
after the underlined original sentences, it means that the underlined sentences are refined. A
number in the parentheses after a label means that the functional requirement is used
repeatedly.
<Method of clear indication of dependency>
dependency>
The label in the parentheses "( )" in the dependent section indicates a label for the security
functional requirements used in this ST. When it is a dependency that is not required to be used
in this ST, it is described as "N/A" in the same parentheses.

6.2.1.2. Sufficiency
The IT security functional requirements for the security objectives are described as follows.
O.REGISTEREDO.REGISTERED-USER (Usage of a permitted user)
This security objective limits the utilization of MFP installing TOE to only the user who
succeeded in identification and authentication, and needs various requirements regarding
user identification and authentication.

Security Target
<Necessary requirement for identification and authentication of the user>
It identifies and authenticates that the user who accesses is a permitted user by FIA_UID.2 [3]
and FIA_UAU.1 [1].
FIA_UAU.7 returns "*" for each entered character as feedback protected by the panel and
supports the authentication.
In the case of the failure authentication from the panel, FIA_AFL.1 [8] refuses all input
acceptances from the panel for 5 seconds in every failure. When the authentication failure
reaches 1-3 times, FIA_AFL.1 [4] locks the authentication function for that user from then on.
This lock status is released by the administrator's release operation.
FMT_MOF.1 [2] permits only the administrator the selection of the user authentication
methods which are "Machine authentication" and "External server authentication".
FMT_MTD.1 [3] permits only the administrator the setting (modification) of the threshold of
the Authentication failure frequency which is the trial frequency of the failure authentication
in the user authentication.
FIA_SOS.1 [5] secures the quality verification of the session information used in the user
authentication via the network, and FIA_SOS.2 secures the quality of the session information
which is generated and used.
<Necessary requirements for managing session of user who is identified and authenticated>
The duration of session of the user who is identified and authenticated contributes to reduce
the chance of attacking associated with unnecessary session connection, by ending the session
after the panel automatic logoff time elapses with FTA_SSL.3. when it logs in from the panel.
The change in the panel auto logoff time is limited to the administrator by FMT_MTD.1 [3].
<Necessary requirement for managing the identification and authentication information of the
user>
When "the machine authentication" is chosen in a method of the user authentication by
FMT_MTD.1 [1], the initial registration of a user password in the user's registration is
permitted only by the administrator.
When "the machine authentication" has been selected in the method of the user authentication,
the registration of the user ID, pause and resumption of use in the user registration is
permitted to the administrator by FMT_MTD.1 [10] and FMT_MTD.1 [13]. When the "external
server authentication" (has been selected in the user authentication method, the user who is
authenticated the identification is permitted from an external server and registered
automatically by this requirement. (This corresponds to the user ID registration of the
"external server".) At this registration, the external server accessing TOE is identified the
external server registered by FIA_UID.2 [7]. This management behavior is maintained as the
role of the external server by FMT_SMR.1 [5]. In addition, the registration function of user ID
is specified for the administration function by FMT_SMF.1.
The registration and change operation of an external server setting is limited to only the
administrator by FMT_MTD.1 [3] and FMT_MTD.1 [11].
The quality of the user password is verified by FIA_SOS.1 [3]. When "machine authentication"
is selected in the method of the user authentication, a change of the user password is limited to
the user itself and the administrator by FMT_MTD.1 [2]. In addition, when a user changes

<Necessary requirement to keep the administrator secure>
refer to set.admin
<Necessary requirement to keep the service engineer secure>
refer to set.service
<Role and management function for each management>
The role to do these managements is maintained as an administrator by FMT_SMR.1 [2] and a
user by FMT_SMR.1 [3]. Moreover, these management functions are specified by FMT_SMF.1.
This security objective is satisfied by the completion of these multiple functional requirements.
O.PRIVATEO.PRIVATE-BOX (personal user box access control)
This security objective limits access to the personal user box and the user box file in the
personal user box to only the user who owns that user box, and needs various requirements
that relate to the access control.
<User box access control (a personal user box)>
After the user has been identified and authenticated, the user ID is associated with the task
of acting a use by FIA_ATD.1 and FIA_USB.1.
By FDP_ACC.1 [1] and FDP_ACF.1 [1], the
task of acting the user has a user ID, and is permitted to display the list of the user box with a
corresponding user attribute. In addition, after the user box has been selected, when the user
box ID is associated with the task of acting a use by FIA_ATD.1 and FIA_USB.1, the
operation such as a print, a download, transmissions, a movement, and a copy is permitted to
the user box file that has a corresponding object attribute to user ID and user box ID of the
subject attribute.
<Management of a personal user box>
FMT_MSA.1 [1] permits to the user and the administrator the change operation of the user
attribute of the user box where the user ID is set.
As for the registration of the user box, public is appointed to the user attribute of the user box
by FMT_MSA.3 [1] and it is permitted only to the user and administrator to give the initial
value to change the public attribute. In addition, when the job to store the non-registered user
box into the user box appointed is executed due to the same requirement, a user ID of the user
who executes a job concerned is appointed automatically.
As for the user box attribute of the user box file, the value consistent with the user box
attribute of the user box which was selected as the file saved is set up by FMT_MSA.3 [3].

Security Target
<Role and controlling function for each management>
As the role of doing these managements, FMT_SMR.1 [2] maintains an administrator and
FMT_SMR.1 [3] maintains a user permitted the use of the user box. FMT_SMF.1 specifies
these management functions.
This security objective is satisfied by the completion of these multiple functional
requirements.
O.PUBLICO.PUBLIC-BOX (a public user box access control)
This security objective permits the inspection of the public user box to all users, and limits
the setting of the public user box and the operation of the user function of the user box file in
the public user box only to the user who permitted the utilization of that public user box. And
it needs the various requirements regarding access control.
<User box access control (a public user box)>
After the user has been identified and authenticated, the user ID is associated with the task
of acting a use by FIA_ATD.1 and FIA_USB.1.
FDP_ACC.1 [1] and FDP_ACF.1 [1] permits
the list display operation to the user box where public is set on the user attributes to the task
of acting the user who has user ID.
It is required to be a user who is permitted the use of the user box to operate the user box file
in the public user box. FIA_UID.2 [5] and FIA_UAU.2 [4] identifies and authenticates that it
is a user who is permitted the use of the user box.
FIA_UAU.7 returns "*" for each entered character as feedback protected by the panel and
supports the authentication.
In the case of the failure authentication from the panel, FIA_AFL.1 [8] refuses all input

FCS_CKM.4
<The reason not to fulfill partially FCS_CKM.2 or
FCS_COP.1>
The cryptographic operation is performed using key
generated by Konica Minolta HDD cryptographic key
generation algorithm in the IT environment by
FIT_CAP.1[1]. TSF only uses this capability, and there
is no necessity of the distribution and cryptographic
operation.
FCS_CKM.1 or FDP_ITC.1
or FDP_ITC.2, FCS_CKM.4
<The reason not to apply FCS_CKM.4>
The encryption key temporarily exists in the volatile
memory area, but there is no necessity of the
encryption key cancellation since it is automatically
destroyed without the necessity of access from the
outside.
FCS_CKM.1 (only partial event )
The satisfied events: The encryption key for
enciphering the attached file by the S/MIME
communication is generated.
<The reason not to satisfy a part of the FCS_CKM.1 or
FDP_ITC.1 or FDP_ITC.2>
- It seems proper to use FDP_ITC.1 because the
public key to encrypt the encryption key for the
data encryption of S/MIME is imported outside of
TSF control area, but S/MIME certificate is
registered by the administrator's operation. In that
case, it is unnecessary to consider whether it
passes thorough the untrusted channel or not.
There is not inevitability to apply the security
requirement (The use under the condition that
A.NETWORK is realized) .
- Also, the attribute information of imported
encryption key doesn't apply to the security
attribute used for the access control, etc., is not
related to the initialization, etc., so there is no
necessity to apply.
- In FMT_MTD.1[11], it is expressed as registration
of TSF data, and the object of import operation is
assigned to an appropriate role.
- As a result, the event corresponding to the key
management is explained by using not the security
requirement that is showed in the dependencies
but other security requirement, so that it's no
problem even if this dependency is not satisfied.

6.2.2. Rationale for IT Security Assurance Requirements
This TOE is installed and used in an environment where adequate security is maintained in
terms of the physical, personnel, and connectivity. Nonetheless, adequate effectiveness in the
environment where the TOE is used must be assured. As a general commercial office product,
the execution of tests based on function specifications and TOE design, and analysis of the
strength of function and a search for vulnerabilities are required. In addition, it is desirable that
it has a development environment control, a configuration management for the TOE and a
secure distribution procedure. And therefore the selection of EAL3, which provides an adequate
assurance level, is reasonable.
The secure requirement dependency analysis is assumed to be appropriate because the
package EAL has been selected, therefore details are not discussed.

7.1. F.ADMIN (Administrator Function)
F.ADMIN is a series of security function that administrator operates, such as an administrator
identification authentication function in an administrator mode accessing from a panel or
through a network, and a security management function that includes a change of an
administrator password and a lock cancellation of a locked user box. (Nevertheless, all functions
are not feasible functions through both a panel and a network.)
7.1.1. Administrator Identification Authentication Function
It identifies and authenticates the accessing user as the administrator in response to the
access request to the administrator mode.
Provides the administrator authentication mechanism authenticating by the administrator
password that consists of the character shown in Table 12.
Provides the administrator authentication mechanism using the session information
besides the administrator password, after the administrator is authenticated to the access
from the network,
According to protocol, use the session information of more than 1010, or generate and use
the session information more than 1010.
Return "*" for each character as feedback for the entered administrator password.
Resets the number of authentication failure when succeeding in the authentication.

In the case of access from a panel, it doesn't accept the input from a panel for five seconds
when failing in the authentication.
Locks all the authentication functions to use the administrator password when detecting the
authentication failure that becomes 1-3 times at total in each authentication function by
using the administrator password. (Refuse the access to the administrator mode)
The administrator specifies the failure frequency threshold by the unauthorized access
detected threshold setting function.
F.RESET works and the lock of authentication function is released.

While accessing an administrator mode from a panel, if not accepting any operation during the
panel automatic logoff time, it logs off the administrator mode automatically.
As described above, FIA_SSL.3 is realized.
7.1.3. Function Supported in Administrator Mode
When a user is identified and authenticated as an administrator by the administrator
identification authentication function at the accessing request to the administrator mode, the
administrator attribute is associated with the task substituting the user. And the following
operations and the use of the functions are permitted.
As described above, FIA_ATD.1 and FIA_USB.1 are realized.

User Box Registration
When the administrator attribute is related, the view of the list of user boxes is permitted. A
personal user box, a group user box, and a public user box are registered by selecting the user
attribute to the non-registration user box ID selected from the list of user boxes. When they
are registered, “public” is specified on the user attribute of the user box by default, however, a
user ID or an account ID can be selected.
In the case of the personal user box, the arbitrary user ID registered is specified.

As described above, FCS_CKM.1 is realized.
<Encryption of User box file >
It is encrypted by AES which FIPS PUB 197 provides by using encryption key (128, 192 and
256 bits) to encrypt the user box file.
It is encrypted by the 3-Key-Triple-DES which SP800-67 provides by using the encryption
key (168 bits) to encrypt the user box file.
As described above, FCS_COP.1 is realized.
<Encryption of User box files Encryption key>
The encryption key to encrypt the user box file is encrypted by RSA which FIPS 186-2
provides.
The key length of the encryption key used in this case is 1024, 2048, 3072 or 4096 bits.
As described above, FCS_COP.1 is realized.
7.12. F.FAX-CONTROL (FAX Unit Control Function)
F.FAX-CONTROL is the function that prohibits an access to internal network connected to
MFP through the FAX unit by TOE control.
TOE controls the function that transfer the data received from public line to internal LAN.
The prohibition of access (data forwarding except image data) from public line to internal
network is realized by TOE control.
As described above, FDP_IFC.1 and FDP_IFF.1 are realized.
7.13. F.SUPPORT-AUTH (External Server Authentication Operation Support Function)
F.SUPPORT-AUTH is the function that realizes the user authentication function in
cooperation with the user information management server of Active Directory. (the function that
operates with F.USER.)
When the “external server authentication” is selected for user authentication method, the
inquiry for the authentication information of the user is done for the user information
management server under the user's request of the identification and authentication process.
After this inquiry, the user identification and authentication process is realized by getting the
user authentication information returned back from user information management server.
As described above, FCS_CAP.1 [1] is realized.
7.14. F.SUPPORT-CRYPTO (ASIC Support Function)
F.SUPPORT-CRYPTO is the function that operates the HDD encryption function that utilizes
ASIC from TOE.
For all data written in HDD, an encryption key generated by F.CRYPTO is set in ASIC, and

encryption is performed by the ASIC. On the other hand, for the encrypted data read out of the
HDD, the encryption key generated by F.CRYPTO is set in ASIC in the same manner as above,
and decryption is performed by the ASIC.
As described above, FCS_CAP.1 [2] is realized.
7.15. F.ADMIN-WebDAV (Administrator Function (Counter Management Function))
F.ADMIN-WebDAV is the security function that identifies and authenticates administrator
when accessed via a network from a client PC using WebDAV, and permits only the
administrator who was identified and authenticated successfully to operate the counter
management function. (The counter management function includes TSF data. This is described
in detail below.)
7.15.1. Identification and Authentication Function by WebDAV Server Password
It is identified and authenticated by the WebDAV server password that a user accessing via a
network using WebDAV is an administrator.
Provides the WebDAV authentication mechanism which authenticates the user by the
WebDAV server password consisting of the characters shown in Table 12.
For WebDAV, no separate mechanism to authenticate the administrator based on the
session information, but a WebDAV server password is used for each session.
Resets the number of authentication failure when succeeding in the authentication.
When the authentication failure that becomes the second, fourth, and sixth in total is
detected by each authentication function utilizing a WebDAV server password, all the
authentication functions utilizing a WebDAV server password is locked. (Deny the access
using WebDAV.)
The administrator specifies the failure frequency threshold by the unauthorized access
detection threshold setting function.
The lock is released by the lock release function to the WebDAV authentication of F.ADMIN
executed.
As described above, FIA_AFL.1[9], FIA_UAU.2[2], and FIA_UID.2[2] are realized.
7.15.2. Management Function Utilizing WebDAV
When it is identified and authenticated that the user is an administrator by the WebDAV
server password, access utilizing WebDAV is permitted, and the setup operation of the following
setting data is permitted.
7.15.2.1. Obtention of User Password
User password is obtained for each registered user.
As described above, FMT_MTD.1[7], FMT_SMF.1, and FMT_SMR.1[2] are realized.
7.15.2.2. Obtention of Account Password
Account password is obtained for each registered account.
