1 .2.2 Product Overview
This TOE is the embedded software that is installed on the Konica Minolta Business
Technologies, Inc. digital MFP (bizhub 500 / bizhub 420 / bizhub 360 / ineo 500 / ineo
420 /ineo 360) (Hereinafter referred to as “MFP”). This TOE is on the flash memory on
the MFP controller carried in MFP, and this controls the whole operation of MFP such
as the operation control processing and the image data management received from the
panel of MFP body or the network.
This TOE offers the protection from exposure of the highly confidential document
stored in the MFP, and aims at protecting the data which may be exposed against a
user ’s intention. In order to realize it, this offers the functions such as the function
that limits the operation to the specific document only to the authorized user, the
1
CRP-C0094-01
function that performs the overwrite deletion of the data domain which became
unnecessary and the function that deletes the confidential information including a
setting value. Moreover, this has the mechanism using the unauthorized access
protection function (HDD Lock Function) with which HDD is equipped against the risk
of taking out HDD unjustly which is a medium for storing image data in MFP. And this
offers the encryption key generation function to encrypt the data (including image
data) written to the HDD when the encryption board (option part) is installed on the
MFP controller.
.
1.2.3 Scope of TOE and Overview of Operation
This TOE exists on the flash memory on the MFP controller, which built in the body
of the MFP, and is loaded on the RAM. Figure 1-1 shows the relationship between this
TOE and the MFP. Shaded region on the figure 1-1 indicates the TOE and “*” shows the

Figure 1-1: Hardware structure that relates to TOE
Flash memory is the storage medium that stores the object code of this TOE and it
also stores the message data of each country’s language to display the response
accessed through the panel and network, OS, and so on.
NVRAM is the nonvolatile memory and it stores various setting values
(administrator password, transmission addresses data, etc).
HDD stores the image data as the file, and is also used for the storage area for
swapping the image data which exceeds the capacity of RAM processing area. Also, this
TOE has the HDD lock function that can prohibit the unauthorized reading and
unauthorized writing to HDD by setting the password in HDD.
The encryption board is provided as option parts. The encryption function is installed
on the encryption board to encrypt the data (including image data) written to the HDD
as the hardware-based function.

CRP-C0094-01
Next, the logical structure of this TOE is shown. MFP includes the function that is
not associated with the security directly such as basic function and remote diagnosis
function other than the function that is indicated in “1.2.4 TOE functionality”.
Basic function is a series of function for the office work concerning the image such as
copy, print scan and fax and TOE performs the core control in the operation of these
functions.
Remote diagnosis function is used for managing the operation status of MFP, setup
information, and the device information like the number of prints by using the
methods for the connection, such as the modem connection via RS-232C and the E-Mail,
etc, and communicating with the support center run by the subsidiaries of the Konica
Minolta Business Technologies, Inc.
MFP user who can use these functions uses each function that TOE provides, via the
panel or the network.
The roles of the personnel that relate to the use of the MFP are defined as follows.
1) User
MFP’s user who is registered into MFP (In general, the employee in the
office is assumed.)
2) Administrator
MFP's user who carries out the management of the operation of MFP. An
administrator performs the operation management of MFP and the
management of user. (In general, it is assumed that the person elected from
the employees in the office plays this role.)
3) Service Engineer
A user who performs management of maintenance for the MFP. Service
Engineer performs the repair and adjustment of MFP. (In general, the person
in charge at the sales companies that performs the maintenance service of
MFP and is in cooperation with Konica Minolta Business Technologies Inc. is
assumed.)
4) Person in charge at the Organization that uses the MFP
A person in charge at the organization that manages the office where the
MFP is installed. This person assigns an administrator who carries out the
management of the operation of the MFP.
5) Person in charge at the Organization that manages the Maintenance of the
MFP
A person in charge at the organization that carries out management of the
maintenance for the MFP. This person assigns service engineers who perform
the maintenance management for the MFP.
Besides this, though not a user of TOE, a person who goes in and out in the office
are assumed as an accessible person to TOE.
1.2.4 TOE Functionality
This TOE provides the following functions.
1) Secure Print Function
When the secure print password is received with the printing data, the image
data is stored as the standby status. And the print command and password input
3
CRP-C0094-01
from the panel allows printing.
2) User Box Function
The directory named a use box can be created as an area to store the image file
in HDD. Two types of user box exist; one is the personal user box which a user
possesses and the other is the public user box which the registered user making a
group within a certain number uses jointly.
TOE offers the functions to the user box and the image file in a user box such as
downloading from the client PC, deleting, and setting of the period to keep (delete
automatically by the fixed time passed), and also the change of user box name, the
change of the password, the deletion of the user box, and the attribute setting of
user box from the panel or the network unit. (Upon request via the network from
the client PC.)
3) User Authentication Function
TOE can limit the user who uses MFP. Also, when accessing it via the network,
TOE identifies and authenticates that the user is permitted to use the MFP by
applying the user ID and user password. When the identification and
authentication succeeds, TOE permits the user the use of the basic function and
the user box function, etc. Two types of user authentication methods exist; one is
the “Machine Authentication” that registers the user ID and user password into
HDD on MFP controller, and another is the “External Server Authentication” that
authenticates the user by using the user ID and the user password that are
registered on the user information management server which is connected by the
intra-office LAN.
4) Administrator Function
TOE provides the functions such as the management of the user boxes, the
management of various settings of the network and image quality, and the
management of user information at the time of machine authentication in the
administrator mode that only authenticated administrator can operate. Also, it
offers the operation setting function related to the behavior of the other function.
5) Service Engineer Function
TOE provides a management function of administrator and a maintenance
function, such as adjusting the device for Scan/Print etc, within the service mode
that only a service engineer can operate.
6) 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 for the prohibition setting of maintenance function(through LAN), it is set by
service engineer separately.
7) HDD Lock Function
HDD has the HDD lock function as measure against the illegal taking out,
when the password is set. The administrator function does the operation
setting of this function and as for the starting operation of MFP, the access to
HDD is permitted by the matching of the HDD lock password set to the HDD
and the one set on the MFP. (Even if HDD is taken out, it is impossible to use
it excluding the MFP that the concerned HDD installed.)
8) Encryption key generation function
The encoding and decoding are processed on the encryption board due to the
reading and writing data in HDD. However, TOE itself does not process the
encryption and decryption. It offers only the function to generate the
4
CRP-C0094-01
encryption key.
The protected assets of this TOE are image files (secure print files) that are
registered by the secure print and image files (user box files) that are stored in the
public user box or personal user box.
Moreover, when the stored data have physically been separated from the jurisdiction
of a user, such as the use of MFP ended by the lease return or being disposed, or the
case of an HDD theft, a user has concerns about leak possibility of every remaining
data. Therefore, in this case, the following data files become protected assets.
a. On Memory Image File
Image file of job in the wait state
b. Stored Image File
Stored image files other than secure print file and user box file
c. Remaining Image 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)
d. File related to the Image
Temporary data file generated in print image file processing
e. Transmission Address Data File
File including E-mail address and telephone numbers that become the
destination to transmit an image
1.3 Conduct of Evaluation
Based on the IT Security Evaluation/Certification Program operated by the
Certification Body, TOE functionality and its assurance requirements are being
evaluated by evaluation facility in accordance with those publicized documents such as
“IT Security Evaluation and Certification Scheme”[2], “IT Security Certification
Procedure”[3] and “Evaluation Facility Approval Procedure”[4].

- Security functions of the TOE shall be satisfied with security functional
requirements described in the security design;
- This TOE shall be developed in accordance with the basic security design;
- Above mentioned three items shall be evaluated in accordance with the CC Part 3
and CEM.
More specific, the evaluation facility examined “bizhub 500 / bizhub 420 / ineo 500 /
ineo 420 Zentai Zentai Seigyo Software Security target” as the basis design of
security functions for the TOE (hereinafter referred to as “the ST”)[1], the evaluation
deliverables in relation to development of the TOE and the development,
manufacturing and shipping sites of the TOE. The evaluation facility evaluated if the
TOE is satisfied both Annex B of CC Part 1 (either of [5], [8] or [11]) and Functional
Requirements of CC Part 2 (either of [6], [9] or [12]) and also evaluated if the
development, manufacturing and shipping environments for the TOE is also satisfied
with Assurance Requirements of CC Part 3 (either of [7], [10] or [13]) as its rationale.
Such evaluation procedure and its result are presented in “bizhub 500 / bizhub 420 /
bizhub 360 / ineo 500 / ineo 420 /ineo 360 Zentai Seigyo Software Evaluation

CRP-C0094-01
1.4 Certification
The Certification Body verifies the Evaluation Technical Report and Observation
Report prepared by the evaluation facility and evaluation evidence materials, and
confirmed that the TOE evaluation is conducted in accordance with the prescribed
procedure. Certification review is also prepared for those concerns found in the
certification process. Evaluation is completed with the Evaluation Technical Report
issued in March 2007 submitted by the evaluation facility and those problems pointed
out by the Certification Body are fully resolved and confirmed that the TOE evaluation
is appropriately conducted in accordance with CC and CEM. The Certification Body
prepared this Certification Report based on the Evaluation Technical Report submitted
by the evaluation facility and concluded fully certification activities.
1.5 Overview of Report
1.5.1 PP Conformance
There is no PP to be conformed.
1.5.2 EAL
Evaluation Assurance Level of TOE defined by this ST is EAL3 conformance.
1.5.3 SOF
This ST claims “SOF-basic” as its minimum strength of function.
This TOE assumes the use in the general office environment that is protected from
the attack of the external network. The access via the panel or the internal network to
TOE is under the management by the administrator and does not assume the complex
attack. Therefore, it is reasonable to assume the attacking ability to attacker is
“low-level.”
Thus, it is adequate with the SOF-Basic.
1.5.4 Security Functions
Security functions of the TOE are as follows.
1) Administrator Function (F.ADMIN)
This is a series of security function that administrator operates, such as an
administrator identification and authentication function in an administrator

This is a check function to permit reading from and writing in the HDD only
when it is verified that the illegal HDD is not installed and is confirmed validity
when the HDD lock password is set to HDD.
When the HDD lock password is set to HDD, the status of HDD is confirmed in
the HDD operation verifying at the time of TOE starting. As a result of status
check, when the HDD lock password certainly being set is returned as the result of
status confirmation, the access to HDD is permitted. If the HDD lock password not
being set is returned, the access to HDD is refused because of an illegitimate
possibility.

2. Conduct and Results of Evaluation by Evaluation Facility
2.1 Evaluation Methods
Evaluation was conducted by using the evaluation methods prescribed in CEM in
accordance with the assurance requirements in CC Part 3. Details for evaluation
activities are report in the Evaluation Technical Report. It described the description of
overview of the TOE, and the contents and verdict evaluated by each work unit
prescribed in CEM.
2.2 Overview of Evaluation Conducted
The history of evaluation conducted was present in the Evaluation Technical Report as
follows.
Evaluation has started on January 2007 and concluded by completion the Evaluation
Technical Report issued in 2007 April. The evaluation facility received a full set of
evaluation deliverables necessary for evaluation provided by developer, and examined
the evidences in relation to a series of evaluation conducted. Additionally, the
evaluation facility directly already visited the development and manufacturing sites
on 2006 June,2006 September, and 2006 October and examined procedural status
conducted in relation to each work unit for configuration management, delivery and
operation and lifecycle by investigating records and staff hearing for other products
that have same assurance level as the TOE. And same processes are executed for the
TOE and the evaluation facility visited the development and manufacturing sites in
March 2007 and examined difference between the processes. Further, the evaluation
facility executed sampling check of conducted testing by developer and evaluator
testing by using developer testing environment at developer site on March 2007.
Concerns found in evaluation activities for each work unit were all issued as
Observation Report and were reported to developer. These concerns were reviewed by
developer and all problems were solved eventually.
As for concerns indicated during evaluation process by the Certification Body, the
certification review was sent to the evaluation facility. These were reflected to
evaluation after investigation conducted by the evaluation facility and the developer.
2.3 Product Testing
Overview of developer testing evaluated by evaluator and evaluator testing conducted
by evaluator are as follows.

a. Test Configuration
The configurations of the tests performed by the developer are shown in
Figure 2-1. Developer testing is performed at the same TOE testing
environment with the TOE configuration identified in ST. However, local
connection unit (option parts) is eliminated from the configuration of Printer.
b. Testing Approach
For the testing, following approach was used.
① Check the change of setting values, the authentication method and the
check of access control, by using the external interface (panel, network, and
power supply OFF/ON) and check the change of output message and its
operation, and the behavior of them. In network, it can access using HTTPS
protocol, TCP Socket (API of TCP base using for the access from application),
Open API (API of XML base using for the access from application) and
SNMP (operate MIB) used by PageScope Web Connection (PSWC). Each
protocol can observe the behavior of security function by sending and
receiving the test data of each protocol using test tool. Also, it can check by
using the test tool that the session information of when using HTTPS
protocol or when using OpenAPI, is generated correctly.
.
②For the security function that cannot verify by using the interface of , it
performs the test procedure for each and checks the adequacy of the
behavior. Outlining of the concerned test is as follows.
・To check that all area overwrite deletion function operates correctly
(
HDD
is
deleted
by
“0x00⇒ 0xFF⇒ 0x00⇒ 0xFF⇒ 0x00⇒ 0xFF⇒ 0xAA⇒ verify,” area of use
for administrator is initialized,)it accepts the method to check by using
the tool to dump display of the HDD contents and to edit.
・To check that the encryption key is appropriately generated, it accepts
the method to refer directly the data on the memory on the terminal
screen connected directly to the machine.
・To check that HDD lock password functions effectively, it accepts the
method to check the error occurrence status by exchanging with other
HDD that is not set the HDD lock password.
・As the behavior of the service mode(separation setting function of telnet)
is restricted by service engineer, the method to observe the display of
operational panel is adopted to confirm the behavior of security
function.
c. Scope of Testing Performed
Testing is performed about 129 items by the developer.
The coverage analysis is conducted and examined to testing satisfactorily
all of the security functions described in the functional specification and the
external interface. Then, the depth analysis is conducted and examined to
testing satisfactorily all the subsystems described in the high-level design
and the subsystem interfaces
d. Result
The evaluator confirmed consistencies
and the actual test results provided by the
the developer testing approach performed
and confirmed consistencies between the
22
between the expected test results
developer. The evaluator confirmed
and legitimacy of items performed,
testing approach described in the
CRP-C0094-01
test plan and the actual test results.
2.3.2 Evaluator Testing
1) Evaluator Test Environment
The evaluator used test configuration that are identical to those used by the
developer.

Outlining of testing performed by the evaluator is as follow.
a. Test configuration
The configuration of the tests performed by the evaluator are shown in
figures 2-1 and 2-2. The evaluator tests were performed in TOE test
environment identical to the TOE configuration identified by ST.
b. Testing Approach
23
CRP-C0094-01
For the evaluator testing, the approach that is same as the developer test
was used.
c. Scope of Testing Performed
The evaluator performed 61 tests in total: 31 independent test and 30
sampled developer tests. As the selection criteria of the test, followings take
into account.
① Security function that is suspected to operate along the specifications
by the developer test.
② More important security function than other security function
③ Security function set as the object of strength of function
④ Function that is used from different interface
Also, intrusion tests performed by evaluator are conducted as follows.
TOE can perform three kinds of operations such as the operation by the
panel, the operation through the network by HTTPS protocol, TCP Socket,
OpenAPI and SNMP, and the operation by power supply OFF/ON of Printer.
The operation by the panel and the power supply OFF/ON of Printer can be
considered impossible to perform the unauthorized operations such as
operation other than assumed usage because of the physical restriction of
Printer and the operation panel. On the other hand, the operation via the
network has broad option and is easy to perform the operation other than
expected input.
With a focus on the items related to the network, 9 intrusion tests were
invented in consideration of the following 3 points.
① Verify the truth of insistence based on the vulnerability analysis of
developer.
② Verify the response to the clear vulnerability, that evaluator thinks.
③ Verify the truth of insistence of the strength of function of developer.
