1 Security
1.1 Introduction
Thank you for purchasing our product.
This User's Guide contains the operating procedures and precautions to be used when using the security
functions offered by the bizhub C658/C558/C458 machine. To ensure the best possible performance and ef-
fective use of the machine, read this manual thoroughly before using the security functions. The administrator
of the machine should keep this manual for ready reference. The manual should be of great help in finding
solutions to operating problems and questions.
This User's Guide (version 1.01) covers the following.
Administrators
<Administrator of the machine>
There are two types of administrators; one who is implemented on the machine in advance, and the other
who is registered by the implemented administrator. The former is called the built-in administrator and the
latter is called a user administrator. Below, the administrator of the machine means the build-in administrator.
<User administrator>
The user administrator is a user who is given the authority to operate the machine as an administrator. The
administrator of the machine or the user administrator can register the user administrator. Be sure that "Pre-
cautions for Operation Control" applies to the user administrator. For details, see page 1-9.
The differences from the administrator of the machine are as follows:
-The same procedure as a user applies to the user administrator when he or she changes the password
or fails authentication.
-To change password, log on to the User Mode.
<Note>
Below, the administrator collectively means both the administrator of the machine and the user administrator.
Compliance with the ISO15408 Standard
When the Enhanced Security Mode on this machine is set to [ON], more enhanced security functions are
available.
This machine offers the security functions that comply with the ISO/IEC15408 (level: EAL2) and U.S. Govern-
ment Approved Protection Profile - U.S. Government Protection Profile for Hardcopy Devices Version 1.0
(IEEE Std 2600.2TM-2009).
Operating Precautions
The machine gives an alarm message or an alarm sound (peep) when a wrong operation is performed or a
wrong entry is made during operation of the machine. (No "peep" alarm sound is issued if a specific sound
setting in Sound Setting of Accessibility Setting is set to [OFF].) If the alarm message or alarm sound is given,
perform the correct operation or make the correct entry according to the instructions given by the message
or other means.
The administrator must not leave the machine with each setting screen left displayed before, during, and after
access to each mode. If he or she has to leave the machine, make sure that he or she logs out and returns
the screen to the authentication screen.
The administrator must make sure that each individual general user logs out and returns the screen to the
authentication screen if he or she leaves the machine with each mode screen left displayed before, during,
and after access to each mode.

1.2 Security Functions 1
1.2 Security Functions
Setting the Enhanced Security Mode to [ON] will validate the security function of this machine. For details of
the settings of different security functions to be changed by turning [ON] the Enhanced Security Mode, see
page 2-12.
The following the major security functions when the Enhanced Security Mode is set to [ON].
Check Count Clear Conditions
In the Enhanced Security Mode, the number of wrong entries at the time of authentication is checked. The
following is the conditions for clearing or resetting the number.
<Administrator Authentication>
-Authentication of Administrator of the machine is successful.
<User Authentication Mode>
-Authentication of User Administrator is successful.
-User Authentication mode is successful.
-Release of Prohibited Functions When Authentication Error is executed.
<Account Track Mode>
-Account Track mode is successful.
-Release of Prohibited Functions When Authentication Error is executed.
Function Description
Identification and au-
thentication function
Access control is then provided through password authentication for any ac-
cess to the Administrator Mode, User Authentication mode, User Box, a User
Box data file, and a Secure Print document. Access is thereby granted only
to the authenticated user. A password that can be set must meet the Pass-
word Rules. The machine does not accept setting of an easily decipherable
password. For details of the Password Rules, see page 1-13.
If a wrong password is entered, during password authentication, a predeter-
mined number of times (once to three times.) or more set by the administra-
tor, the machine determines that it is unauthorized access through Prohibited
Functions When Authentication Error, prohibiting any further entry of the
password. By prohibiting the password entry operation, the machine pre-
vents unauthorized use or removal of data. The administrator is responsible
for resetting the prohibition of the password entry operation. For details, see
page 2-25.
User limiting function Specific functions to be used by each user/account may be limited. For de-
tails, see page 2-39.
HDD encryption function By setting the Encryption Key, the data stored in the HDD is encrypted, there-
by protecting the data in the HDD. For details, see page 2-66.
Auditing function Information including operations performed on the machine and a job history
can be stored in the HDD. Setting the Job Log (Audit Log) allows an illegal
act or inadequate operation performed on the machine to be traced. The ob-
tained Job Log can be downloaded and viewed from the Web Connection.
For details, see page 2-77.
Residual information de-
leting function
When the machine is to be discarded or use of a leased machine is terminat-
ed at the end of the leasing contract, setting of the Overwrite HDD Data func-
tion while the machine was in use allows residual unnecessary data to be
deleted, because the machine overwrites a specific overwrite value over the
unnecessary data. This prevents data leakage. (Passwords, addresses, and
other data set while the machine was in use should, however, be deleted
manually.) For details, see page 2-72.
To delete data including the passwords, addresses, and other data all at
once, the Overwrite All Data function overwrites and erases all data stored in
all spaces of the HDD. The function also resets all passwords saved in the
flash memory and eMMC to factory settings, preventing data from leaking.
For details, see page 2-74. For details of items to be cleared by Overwrite All
Data function, see page 1-16.
Network communication
protecting function
Communication data transmitted to or from the machine and client PC can
be encrypted using the IPsec, which prevents information leakage through
sniffing over the network. For details, see page 2-95.

1.3 Precautions for Operation Control 1
1.3 Precautions for Operation Control
This machine and the data handled by this machine should be used in an office environment that meets the
following conditions. The machine must be controlled for its operation under the following conditions to pro-
tect the data that should be protected.
Roles of the Owner of the Machine
The owner (an individual or an organization) of the machine should take full responsibility for controlling the
machine, thereby ensuring that no improper operations are performed.
-The owner of the machine should have the administrator recognize the organizational security policy
and procedure, educate him or her to comply with the guidance and documents prepared by the man-
ufacturer, and allow time for him or her to acquire required ability. The owner of the machine should
also operate and manage the machine so that the administrator can configure and operate the machine
appropriately according to the policy and procedure.
-The owner of the machine should have users of the machine recognize the organizational security policy
and procedure, educate them to follow the policy and procedure, and operate and manage the machine
so that the users acquire the required ability.
-The owner of the machine should vest the user with authority to use the machine according to the or-
ganizational security policy and procedure.
-The owner of the machine should operate and manage the machine so that the administrator checks
the Job Log (Audit Log) data at appropriate timing to thereby determine whether a security compromise
or a faulty condition has occurred during an operating period.
-If the Job Log (Audit Log) data is to be exported to another product, the owner of the machine should
ensure that only the administrator performs the task. The owner of the machine should also operate and
manage the machine so that the Job Log (Audit Log) data is not illegally accessed, deleted, or altered.
Roles and Requirements of the Administrator
The administrator should take full responsibility for controlling the machine, thereby ensuring that no improp-
er operations are performed.
-A person who is capable of taking full responsibility for controlling the machine should be appointed as
the administrator to make sure that no improper operations are performed.
-When using an external authentication server, an SMTP server (mail server), or a DNS server, each serv-
er should be appropriately managed by the administrator and should be periodically checked to confirm
that settings have not been changed without permission.
Password Usage Requirements
The administrator must control the Administrator Password, Encryption Key, FW Update (USB) Password,
and User Box Password appropriately so that they may not be leaked. These passwords should not be ones
that can be easily guessed. The user, on the other hand, should control the Secure Print Password and User
Password appropriately so that they may not be leaked. Again, these passwords should not be ones that can
be easily guessed.
<To Achieve Effective Security>
-Make absolutely sure that only the administrator of the machine knows the Administrator Password.
-Make absolutely sure that only the administrator knows the Encryption Key, FW Update (USB) Pass-
word, and User Box Password.
-Make sure that the administrator of the machine changes the Administrator Password regularly.
-The administrator must change the Encryption Key, FW Update (USB) Password, and User Box Pass-
word at regular intervals.
-The administrator of the machine should make sure that any number that can easily be guessed from
birthdays, employee identification numbers, and the like is not set for the Administrator Password.
-The administrator should make sure that any number that can easily be guessed from birthdays, em-
ployee identification numbers, and the like is not set for the Account Password, Encryption Key, FW
Update (USB) Password, and User Box Password.
-If a User Password has been changed, the administrator should have the corresponding user change
the password as soon as possible.
-If the Administrator Password has been changed by the Service Engineer, the administrator of the ma-
chine should change the Administrator Password as soon as possible.

bizhub C658/C558/C458 1-10
1.3 Precautions for Operation Control 1
-The administrator should have users ensure that the passwords set for the User Authentication, Secure
Print, and the box that can be used by the user are known only by the user concerned.
-The administrator should have users change the passwords set for the User Authentication at regular
intervals.
-The administrator of the machine should have the user administrator log on to the User Mode and
change his or her password in [Utility] - [User Settings] - [Change Password] if he or she changes the
password.
-The administrator should make sure that any user does not set any number that can easily be guessed
from birthdays, employee identification numbers, and the like for the passwords set for the User Au-
thentication and Secure Print.
-The administrator should disclose the Account Password to the user in accordance with the operating
environment of the machine and the security policies of the organization on his or her own responsibil-
ity.
External authentication server control requirements
The administrator and the server administrator are required to apply patches to, or perform account control
for, this machine and the external authentication server connected to the office LAN in which the machine is
installed to ensure operation control that achieves appropriate access control.
This machine can be used only after the user who uses this machine has been registered in the external au-
thentication server. The server administrator should also check registered users at regular intervals to thereby
ensure that any unnecessary users are left registered.
Security function operation setting operating requirements
The administrator should observe the following operating conditions.
-The administrator should make sure that the machine is operated with the settings described in the in-
stallation checklist made properly in advance.
-The administrator should make sure of correct operation control so that the machine is used with the
Enhanced Security Mode set to [ON].
-The administrator should make sure of correct operation control so that the appropriate FW Update
(USB) Password is used with [FW Update (USB) Permission Setting] set to [Password Priority].
-When the Enhanced Security Mode is turned [OFF], the administrator is to make various settings ac-
cording to the installation checklist and then set the Enhanced Security Mode to [ON] again. For details
of settings made by the service engineer, contact your service representative.
-When the machine is to be discarded or use of a leased machine is terminated at the end of the leasing
contract, the administrator should use the Overwrite HDD Data function and the Overwrite All Data
function to thereby prevent data to be protected from leaking.
Operation and control of the machine
The administrator should perform the following operation control.
-The administrator should log off from the Administrator Mode whenever the operation in the Adminis-

Precautions for Use of Various Types of Applications
Comply with the following requirements when using the Web Connection or an application of various other
types
The administrator should make sure that the user observes the following requirements.
-The password control function of each application stores the password that has been entered in the PC
being used. Disable the password management function of each application and perform an operation
without storing a password.
Use a web browser or an application of various other types that shows "*" or "-" for the password en-
tered.
-Once the password has been entered, do not leave your PC idle without logging on.
-Set the web browser so that cache files are not saved.
-Do not access any other site once you have logged onto the machine with the Web Connection. Ac-
cessing any other site or a link included in e-mail, in particular, can lead to execution of an unintended
type of operation. Whenever access to any other site is necessary, be sure first to log off from the ma-
chine through the Web Connection.
-Using the same password a number of times increases the risk of spoofing.
-If a web browser such as Internet Explorer is used on the client PC side, "TLS v1.0" or more should be
used for the SSL setting.
-Optional applications not described in this User’s Guide are not covered by certification of ISO15408.
Encrypting communications
This machine guarantees encrypted communication via IPsec.
IPsec setting
This machine offers a choice of two authentication methods of [Pre-Shared Key] and [Digital Signature] for
authenticating the remote machine with which to communicate.
When [Pre-Shared Key] is to be used, control the pre-shared key appropriately to ensure that it is not leaked
to any third party other than the remote machine with which to communicate. For the shared key, set a value
that consists of a combination of eight or more alphanumeric characters and that cannot be easily guessed.
Do not set a value that can be easily guessed from your birthday, employee identification number, and the
like.
[Digital Signature] has a higher security strength than [Pre-Shared Key].
The ISO15408 evaluation for the machine is performed on the basis of the [Pre-Shared Key].
[Main Mode] and [Aggressive Mode] are available in [Negotiation Mode] of [IKE Settings]. The default setting
is [Main Mode]. The administrator should operate the machine with the [Main Mode] setting.
Leaking the pre shared key for IPsec set on the MFP increases the risk of spoofing of the MFP, etc. Therefore,
set machine-specific pre shared keys and manage them safely.
Note that unencrypted communication can be established if the IPsec setting is not made over the whole ad-
dress range (0 to 255 for IPv4) and an IP address outside the range is assigned to a client PC.
NOTICE
The administrator of the machine should make sure that SSL encryption communication is not performed with
the SSL set in SSL v3.
Do not use an SSL certificate that is electronically signed by MD5, as an increased risk results of data to be
protected being tampered with or leaked.
To eliminate the risk of the data to be protected being tampered with or leaked, refer to the recommended
ciphers list disclosed by, for example, NIST and CRYPTREC and use the appropriate cryptographic tech-
nique.

1.4 Miscellaneous 1
Use the following browsers to ensure safety. Use of any of the following browsers achieves communication
that ensures confidentiality of the image data transmitted and received.
Microsoft Internet Explorer
-9/10/11
Mozilla Firefox
-20 or later
Microsoft Internet Explorer 11 is used for the ISO15408 evaluation for this machine.
Print functions
Only the following procedures are guaranteed for the print functions performed from the client PC.
-Use IPPS printing for the print functions performed using the printer driver.
-Use direct printing from the Web Connection for the print functions not performed via the printer driver.
IPP printing
IPP (Internet Printing Protocol) is a function that allows printing via the Internet by using the HTTP (HyperText
Transfer Protocol) of the TCP/IP Protocol. IPPS (IPP over SSL/TLS) is the type of IPP that performs the SSL
encryption communication.
<Installing printer driver>
To perform IPPS printing, the printer driver must be installed. Start the printer addition wizard of the Windows
Vista/7/8/8.1/Server 2008/Server 2008 R2/Server 2012/Server 2012 R2 and type [DNS Host Name] and
[Default DNS Domain Name] of this machine in the following format in the "URL" field.
https://[DNS host name].[default DNS domain name]/ipp
For [DNS host name] and [default DNS domain name], specify the names set with the DNS server.
<Registering the certificate in Windows Vista or later>
Windows Vista or later, which offers enhanced security functions, gives a certificate error message if the SSL
certificate is one that is not issued by a certification body. In such cases, it becomes necessary to register
the certificate of this machine as that issued by a reliable party for the computer account.
First, register Host Name and IP address of this machine in the DNS server in advance. Then, in TCP/IP Set-
tings of Web Connection, set the DNS Host Name and DNS Default Domain Name registered with the DNS
server.
It should also be noted that, for the certificate to be imported, a certificate for SSL encryption communication
should be registered in Web Connection and exported in advance as the certificate including the public key.
1From "Continue to this website," call the Web Connection window to the screen.
2Click "Certificate Error" to display the certificate. Then, click "Install Certificate" to install the certificate.
3Display the physical stores. Then, deploy the certificate, which has earlier been exported, in "Local
Computer" of "Trusted Root Certification Authorities" to thereby import the certificate.
