Security Without Sacrifice
Cause for Concern Everywhere –
Security Vulnerability
Konica Minolta Security Standards
Konica Minolta realized early on the importance of security issues in the digital
age, where the risk of seriously damaging security breaches rises dramatically
alongside rapidly growing worldwide communication possibilities.
In response to these threats, Konica Minolta has taken a leading role
in developing and implementing security-based information technology
in our multi-functional products. Ever since the introduction of the first
Konica Minolta MFP, Konica Minolta has striven to develop and implement
technology that safeguards the confidentiality of electronic documents.
The most important security standard in Europe is ISO 15408, also known
as Common Criteria certification. Konica Minolta has newly introduced
multi-functional bizhub products validated to Common Criteria EAL3
security standards. Common Criteria (CC) is the only internationally
recognized standard for IT security testing. Printers, copiers and software
with ISO 15408 certification are security evaluated, and guarantee the
security levels that companies look for today. With the CC certification
users can rest assured that on Konica Minolta’s multi-functional devices
their confidential data remains confidential.
This document discusses various generally important security requirements, and explains how Konica Minolta MFPs comply with the rules and
regulations set forth in ISO 15408 (Common Criteria).
ISO 15408 certification and IEEE P2600.1/P2600.2 protection profile for
hard copy devices.
It is important to note that the P2600 specification has been dropped by
NIAP. A new specification for MFPs is expected by the end of 2014.
Konica Minolta MFPs will continue to achieve ISO 15408 Common
Criteria certification at EAL 3+ together with IEEE P2600.1.
Generally MFPs offer a huge range of combined and single functions and
choices; therefore they represent a similarly wide range of potential security
loopholes. The scope of MFP security could be grouped into three main sections:
Access Control/Access Security
Despite security being high on the agenda in both public and corporate
domains, MFPs are often ignored as being a security risk at all. While
some risks are perhaps identified, they are often simply neglected,
especially where sensitive documents and information is concerned. This
is especially risky for those MFPs and printers located in public areas,
where they can be accessed by staff, contractors and even visitors.
Because the advanced features available on today’s MFPs deliberately
make it easy for information to be copied and distributed within and
beyond actual and virtual corporate boundaries, the first logical step is to
prevent unauthorized persons being able to operate an MFP. Preventive
measures are needed, firstly to control access to MFPs, and secondly to
establish some kind of security policy reflecting how the devices are actually used in real life - obviously none of these measures should restrict or
limit the user-friendliness of the systems. Konica Minolta is prepared for
this, offering various security features and solutions.
Document Security/Data Security
Reflecting the fact that MFPs and printers are often located in public areas,
where they can be easily accessed by staff, contractors and visitors, it is
necessary to implement appropriate data security policies. The situation
is after all that confidential data, for example stored on the MFP hard disk
over a period of time, or simply confidential documents lying in the MFP
output tray as printouts, are initially unprotected and could fall into the
wrong hands. Konica Minolta offers a range of tailored security measures
to ensure document and data security.
Network Security
ISO 15408 is divided into seven levels of EAL
(Evaluation Assurance Level) certification.
Standard off-the-shelf products can only achieve
up to EAL4 certification. Most IT-related products
are certified at EAL3. A certification lab in Japan
tests Konica Minolta products. Konica Minolta
certifications and related documentation can
be found at the following website:
In today’s corporate environment, indeed in today’s business world,
communications and connectivity are indispensable. Konica Minolta
office devices are designed to integrate into network environments. For
example, network printers and multi-functional peripherals (MFP) have
evolved to the point that they act as sophisticated document processing
hubs integral within the network, with the ability to print, copy and scan
documents and data to network destinations, send emails and more. This
scenario also means that this office technology must cope with and comply with the same security risks and policies as any other network device,
and represents a risk if unprotected. In order to avoid any vulnerability
from either internal or external network attacks, Konica Minolta ensures
that all equipment complies with the strictest security standards. This is
achieved using a number of measures.
With its comprehensive range of security features, Konica Minolta provides
professional solutions for the detection and prevention of security breaches.

General System Security
Security of RAM
There are three types of RAM currently used in bizhub products:
Protection Against Virus from USB Memory
Most of the Konica Minolta devices are equipped with an interface for
USB memory sticks. This offers the possibility to print documents directly
from the USB memory without a PC. It is also possible to scan documents
directly to the USB memory.
Generally, virus infection from USB memory is caused by program files
automatically executing when the USB memory is inserted in the device.
Konica Minolta devices do not support functionality to automatically execute files by inserting the USB memory. Therefore, Konica Minolta devices
are not affected by these types of viruses.
Security for Fax Line
Any communication via fax line uses only fax protocol and does not support any other communication protocol. If someone from outside attempts
to intrude with a different protocol via a public line, or tries to send data
that cannot be decompressed as fax data, Konica Minolta products
handle the event as an error and block such communication.

protocol protocol
Check whether
correct command
response by G3
protocol is made
or not.
If G3 protocol is used, the
communication is continued. But if anything
other than G3 protocol is
used, the communication
is blocked off.
Volatile RAM – typically volatile RAM would be:
• file memory
• electronic sorting
• work memory
• storing program parameters, temporary data and
image conversion of controller
• fax memory
• working RAM for fax
Data written to volatile RAM is held while the power is on. The data held
in this type of RAM is overwritten by the next page or job being printed.
Once the job is printed the data is deleted from the RAM. Also, as soon as
the power is turned off the data in volatile RAM is deleted. Volatile RAM is
secure: if RAM is removed after an engine is powered off, all the data on
that RAM chip will have already been deleted. It is impossible to remove
the RAM while the engine power is on. The only other way to possibly
extract data would be via an indirect route or a security hole.
These access points are evaluated and tested by independent security consultants before the Konica Minolta products are submitted for ISO 15408
certification. There are no indirect routes or security holes in bizhub MFPs.
Non-volatile RAM (NV-RAM) – typically non-volatile RAM would be:
• counter data
• job settings
Security of Remote Diagnostic Services
• utility settings
The remote diagnostic system uses a public telephone line for communication between the Konica Minolta system and the service center. With
this system, Konica Minolta devices send main-body data to the service
center; and the service center can transmit data to change the main-body
settings remotely. An ID preset on every main body and service center
ensures that communication is only enabled if the IDs match.
The data written to non-volatile RAM is not image or document data,
meaning the data is not confidential or private. Unlike volatile RAM this
data is not cleared when the power is turned off. It is important to note
that when the HDD is formatted, the user/account data in NV-RAM will be
deleted and reset to factory default.
Flash memory – typically flash memory is utilized with:
• machine firmware

1. Call for
registration of communication
• control panel data
• printer-resident fonts
• copy-protect watermarks
4. Check the password and then start
5. Send the data
describing device status
Flash memory is embedded on an MFP circuit board and cannot be erased.
The data stored in flash memory is not critical, confidential or private.
Password Handling
In general, all passwords are handled securely by the MFP following
several security rules:
1. Independent of the functionality the setting of a password always
has to be verified once.
2. All passwords entered via MFP panel, Web interface or application
appear on the screen as “xxx” to prevent illegal copying.
© Copyright. All rights reserved. 2016.
3. All passwords are encrypted for storage.
4. All passwords contain at least 8 to 64 alphanumeric characters.
Depending on the MFP functionality, passwords can be even longer.
Internal authentication at the machine can support up to 1,000 user
accounts. Passwords can have up to eight alphanumeric characters.
5. P asswords transferred via a network can always be transmitted
6. P asswords for user authentication and user boxes can only be reset
by the administrator.
7. Administrator passwords can only be reset by a Konica Minolta
certified engineer.
Password protection
Passwords can be created for administrators and users, and can be
alphanumeric with up to eight characters. An administrator can maintain
passwords. Passwords are protected by the Kerberos system or SSL.
Access Control
Copy/Print Accounting
Konica Minolta bizhub MFPs come with the ability to enable account
tracking as standard. When this function is activated, a user is required
to enter a 4–8 digit personal identification number (PIN) to gain access to
make a copy, send a print, or perform other functions at the MFP. If a user
does not submit or enter an authorized PIN (from the print driver), the print
job submitted will not be printed. If a user does not enter an authorized
PIN at the copier control panel, they will be denied access to the system.
When logged in, the user’s activities are electronically recorded onto a log
file inside the system. An administrator or key operator can access this file.
This is a very popular feature for many customers, who use this to invoice
departments and audit employees’ copier activities. In addition, it is possible
to configure individual copy and print limits per user.
These are examples of the authentication screen from the Konica Minolta
bizhub C654 control panel and printer driver.
User Authentication – Finger VeinScanner
This is an example of the accounting screen from the Konica Minolta
bizhub C654 control panel.
Besides authentication via user ID and password, use of a biometric
device is also possible. The data for the biometric authentication device,
is handled securely and cannot be used illegally.
User Authentication - ID and Password
The vein in the finger as biometric data:
The vein is located within the body and, unlike fingerprints, it cannot
be scanned/read without the person noticing. This makes it virtually
impossible to forge.
Supported external servers like Active Directory, Novell NDS, NTML
v.1 and NTLMv.2; a maximum of 64 characters can be utilized. Active
Directory can support up to 20 domains.
The process implemented in this system:

Result of
Auto Log Off
Konica Minolta MFPs can be programmed to automati­­cally reset to a
state that requires password input after a predetermined time of inactivity.
This ensures that the MFP will reset to a secure state if a user forgets to
log off from an MFP when finished. Note that the reset timer can be set
from 1 to 60 minutes. Some Konica Minolta MFPs can be programmed to
reset in as little as 30 seconds. If the machine has the account tracking
function enabled the machine will enter a state (after a pre-programmed
period of inactivity) that requires a user to enter a unique PIN
or password. This function should satisfy most concerns about users
forgetting to log off after they have finished scanning or copying
documents at the MFP.
Reconstruction of the biometric data:
The only data registered on the HDD are random numbers calculated
on the basis of the feature of the scanned data, and it is theoretically
impossible to reconstruct the original vein data from the data in the HDD.
Structure of the data on the HDD:
The structure of the data on the HDD is not made public. This makes it
impossible to forge.
Erasing of data in the authentication device:
The data left in the device is encrypted when temporarily stored in the
RAM, and is erased after transferring to the MFP.
User Authentication – IC Card Reader
As a third authentication solution, Konica Minolta MFPs can be equipped
with an IC card reader. The non-contact IC card contains a unique code
which is linked in the MFP authentication database to a user ID and password. The biometric data, the IC card code and user information are stored
in an encrypted form on the MFP hard disk, and are therefore protected.
This screen illustrates the administrator and user auto log-off timer setting
that is accessible via the MFP’s remote Web browser-based interface
(PageScope Web Connection).
Function Restrictions
An advanced level of user security allows or prohibits the use and
availability of specific machine features. A user and/or administrator can
control these features as needed throughout an organization of any size.
The specific features are:
• scanning from the bizhub as a walk-up function or a remote function
• user box from the bizhub as a walk-up function or a remote function
• copying from the bizhub as a walk-up function, including the
restrictions of only b/w copying or only color copying or neither b/w
nor color copying
• faxing from the bizhub as a walk-up function or a remote function
© Copyright. All rights reserved. 2016.
• printing as a remote function via the printer driver, including the
restrictions of only b/w printing or only color printing or neither b/w
nor color printing
Function restrictions can be set in general either as a walk-up functionality
or per user, depending on the user authentication.
Touch & Print/ID & Print
If the machine is set up with user authentication, server or MFP-based,
secure printing can be used via the Touch & Print or ID & Print feature.
Instead of an additional secure print ID and password, the user authentication data will be used to identify a stored secure print job, and will
release the job after authentication at the device. This will avoid print jobs
being released before the user can remove them from the output bin,
which will prevent confidential data being viewed by other persons.
Touch & Print is based on authentication via finger vein scanner or IC card
reader. ID & Print is based on user authentication via ID and password.
User Box Password Protection
This is an example of the function permission screen from the
Konica Minolta bizhub C654 control panel.
The user box offers the functionality to store commonly used copy, print,
scan or fax documents on the hard disk of the MFP. Besides the general
security features given to the hard disk, these user boxes can be set
with different access levels. On a walk-up MFP the user boxes can be
protected by an eight-character alphanumeric password.
Secure Print (Lock Job)
Konica Minolta MFPs offer a standard feature called secure printing. This
feature provides a user sending a print job with the ability to hold the job
in the memory of the system until the authorized user walks up to the
machine and releases the job by entering a unique secure PIN/password
at the control panel of the MFP. This code is first specified by the user
when he submits his print job from the PC workstation, ensuring that only
the sender of the job can access an electronic document that contains
sensitive electronic information. In addition, those MFPs equipped with a
hard drive have the ability to store digital data inside the system. When
these documents are stored – either by sending them from a PC or by
scanning them in at the copier – users cannot retrieve the document
unless a secure PIN/password is entered on the copier’s control panel.
This is an example of set user box registration on the bizhub C654 panel.
If the MFP is set up with authentication, the user boxes can be set as a
personal box (only vis­ible for the linked authenticated user), group box
(only visible for users who are set up to view the box) or public box.
The access to the user box is automatically given via
the authentication. But the additional security keeps
all users from seeing the box; therefore they have no
opportunity to hack into it by trying out passwords.
This is an example of the secure print screen from
the Konica Minolta bizhub C654 printer driver.

view on the bizhub
C654 panel.
The encryption key can be set individually by the machine administrator
with a length of up to 20 digits. If the encryption key is not used by the
local user or the print server, print jobs will be printed anyhow. However,
confidential user access information might not be safe.
Password for Non-Business Hours
If an MFP is not set up with user authentication, but
instead is used as a walk-up device, basically anybody
can access the machine and print/send data that is not secure. To
prevent this happening, the administrator can program a “business time
frame”, during which the machine can be used as a walk-up device, while
outside this period a password is necessary to access the machine.
Event Log
All Konica Minolta MFPs offer the option to record all actions that have
happened on the MFP, e.g. a print job including sender name, document
name and password. These event logs or histories can be downloaded
and viewed by the administrator.
To automate the process of event-log downloading, the PageScope Log
Management utility is available to register and view any actions happening
on the MFPs in the network.
This is an example of MFP (bizhub C654) password entry during non-business hours.
Data Security
Hard Disk Password Protection
The built-in hard disk of the MFP is automatically protected by a password.
This password is stored in the hard disk BIOS and prevents access to the
hard disk data, as long as the correct password has not been entered.
Therefore, even the removal of the hard disk and installation into a PC,
This is an example of the Log Management Utility user interface.
Driver User Data Encryption
For secure printing, print authentication and print accounting it is necessary for the user to input certain information, e.g. user ID and password,
in the driver window for transmission to the MFP. To avoid network
information from being sniffed, such user data can be encrypted by the
printer driver and decrypted on the MFP.
This is an example of MFP password entry in the administration mode for
hard-disk protection (bizhub C654).

laptop or other MFP would not give access to the hard disk. The password
is allocated automatically but can be changed by the machine administrator.
Data Encryption (Hard Disk)
Konica Minolta offers either a standard hard drive encryption kit or an
advanced version as an optional extra. If desired, electronic documents
can be stored in a password-protected box on the hard drive. If an
organization is concerned about the security of such data, this can be
pro­tected by encrypting it with the HD encryption kit available. The stored
data is encrypted using the advanced encryption standard AES 256 key
size. Once a HDD is encrypted its data cannot be read, even if the HDD is
removed from the MFP.
Hard Disk Data Overwrite
When equipped with a hard disk drive (HDD), Konica Minolta MFPs can
store sensitive electronic information. The data can be deleted by those
users who own the documents that reside inside the MFP’s HDD in password-protected boxes. For added safety, a key operator, administrator or
technician can physically format (erase) the HDD if the MFP needs to be
relocated. The hard drives can be overwritten (sanitized) using a number
of different methods conforming to various (e.g. military) specifications,
as listed in the table below.
This is an example of the HDD overwrite settings of the MFP
(bizhub C654).

Network Security
Temporary Data Deletion
Depending on the file size for certain jobs, the MFP might use the hard
disk to swap data for copy, scan, print and fax information. As additional
security to protect the information stored on the hard disk, the machine
can be set to format and overwrite this data on a per-job basis. Under this
setting the temporarily swapped data is immediately deleted and overwritten as soon as the data is no longer necessary to end the job in action.
Mode 1
Overwrite with 0x00

IP Filtering
IP address filtering can be set at the machine where the network interface
card of the MFP can be programmed to permit or prohibit access to the
device for a specific range of IP addresses for client PCs.
For the temporary data deletion two modes are available.

Data Auto Deletion
The administrator can set an auto deletion timer for data stored in the
personal or public user boxes, as well as system boxes (e.g. secure print
box or encrypted PDF print box). The auto deletion setting will erase the
copy, print, scan or fax jobs stored in boxes, depending on the storage
period and the time frame selected for deletion.
The screen shot illustrates the PageScope Web Connection administrator
access to a bizhub C654. Here an administrator can set access permission
or refusal to a specific range of IP addresses.
Port and Protocol Access Control
To prevent unnecessary open communication lines on the MFP, open
ports and protocols can be opened, closed or enabled and disabled
through the administration mode at the machine or remotely via
PageScope Web Connection or PageScope Net Care.
This is an example of the MFP setting for user box document auto
deletion (bizhub C654).
The following ports can be opened or closed:
Port 20 – FTP
Port 123 – NTP
Port 21 – FTP
Port 161 – SNMP
Port 25 – SMTP
Port 389 – LDAP
Port 80 – HTTP
Port 631 – IPP
Port 110 – POP3
Port 636 – LDAP
Port 9100 – PDL
The following protocols can be enabled or disabled:
© Copyright. All rights reserved. 2016.
SSL/TLS Encryption (https)
The data communication via network to specific databases or applications
can be encrypted by SSL (Secure Sockets Layer) or TLS (Transport Layer
Security). Supported versions of encryption are SSL 2.0, SSL 3.0 and TLS 1.0.
The encryption of network communication is essential with regard to the
transmission of, for example, authentication data or administrator passwords.
Communication can be encrypted for:
• LDAP protocol
• PageScope Data Administrator
• SMTP protocol
• P ageScope Address Book
• POP protocol
• IPP (IPPS) protocol
• Windows Active Directory
• P ageScope Web Connection
• PageScope Enterprise Server
The MFP allows the programming of an SSL certificate via the administrator mode of PageScope Web Connection.
This is an example of MFP IPsec/IKE settings via the MFP panel
(bizhub C654).
IEEE 802.1x Support
IEEE 802.1x is a port-based authentication standard for network access
control to WAN and LAN networks.
The screen shot illustrates the PageScope Web Connection administrator
access to the security settings for SSL certificates.
IPsec Support
To complete the encryption of any network data transmitted to or from the
MFP, the bizhub devices also support IPsec
(IP security protocol). This protocol encrypts the whole network communication between the local intranet (server, client PC) and the device itself.
The IPsec protocol can be programmed via the IKE settings. Up to four
groups of IPsec/IKE settings can be stored.
This is an example of the MFP 802.1x authentication settings.
© Copyright. All rights reserved. 2016.
The IEEE 802.1x authentication standard generates a secure network by
closing any network communication (e.g. DHCP or HTTP) to unauthorized
devices except for authentication requests. This prevents devices gaining
access to a network by sim­­ply acquiring an IP address via DHCP and, for
instance, performing a man-in-the-middle attack to sniff data streams on
the network.
Only proper authentication, a password or certificate entered by the
authenticator will grant access to the secure network.
NDS Authentication
NDS authentication is a method of user identification that performs
authentication based on a specified server, an entered user name and
password for NDS (Novell Directory Services) run­ning on NetWare 5.1 or later.
Conventionally, NDS authentication only supported IPX/SPX communication
protocols. However, the most recent MFPs also support NDS authentication
via TCP/IP. NDS authentication can be performed by specifying either IPX/
SPX or TCP/IP protocols. NDS authentication via TCP/IP obtains the IP
address of the NDS authentication server by requesting the DNS server
for a specified tree and context.
OpenAPI Communication
Most of the Konica Minolta devices are equipped with OpenAPI. OpenAPI
is Konica Minolta‘s own application programming interface. This gives
users the option of integrating Konica Minolta devices into application-controlled workflows.

Communication by SSL
(Secure Socket Layer)
bizhub OpenAPI acquires and sets the data received from devices via
networks using the SSL encryption protocol. By using an original
password, communication is rendered more secure.
When managing the important data of the device (e.g. setting information
on user authentication), the data is safely protected.
Remote Panel
The latest generations of Konica Minolta devices offer the option of a remote
panel. This means administrators are able to have real time access to

the MFP panel remotely, e.g. via a Web browser. Every function which is
available on the MFP panel can also be executed remotely.
Scan Security
There are various settings with which the remote panel feature can be
configured, made secure or disabled.
To secure access of the MFP with the intranet email server, it is possible
to authenticate with an email account (POP3 – Post Office Protocol)
before an email is sent via the email server. This avoids the possibility
of unauthorized email traffic with the intranet email server, and with the
domain/email suffix respectively.
In addition to the above email security, APOP (Authentication for Post
Office Protocol) can be set. APOP is an authentication method with
encrypted passwords which ensures increased safety in comparison to
the usual unencrypted password exchange used by POP for the retrieval
of email messages.
SMTP Authentication (SASL)
SMTP (Simple Mail Transfer Protocol) authentication can be activated on
bizhub MFPs. This authorizes a device to send emails. For those customers who do not host their email services, the use of an ISP mail server is
possible and supported by the machine. SMTP authentication is required
by, for example, AOL and for the prevention of SPAM.
For email transmission, the MFPs support S/MIME (Secure/Multipurpose
Internet Mail Extensions) encryption.
S/MIME encryption is based on email certificates that can be registered on
the MFP for all stored email addresses. The encryption of the email information by the “public key” (given via the certificate) prevents the sniffing
and unauthorized decryption of email information at a high security level.
For example, if an email is sent accidentally to a wrong destination, the
email information can still only be opened by the intended recipient, who is
the only one in possession of the “private key” necessary for decryption.
Encrypted PDF
bizhub OP-based products can encrypt scanned files in PDF format
before sending them to a destination across the network. The user has
the ability to encrypt a scanned file by selecting the encryption key on
the bizhub’s control panel. The encryption option supports the PDF file

PageScope Web Connection.

type, and will require the decryption code to open the file from the recipient
of the scan. This feature is very similar to the Adobe Acrobat encryption
process where a password is utilized for encryption and opening
a file, as well as to access the permissions area of the encryption process.
PDF Encryption via Digital ID
PDF data that is attached to an email or sent to an FTP or SMB folder can
be encrypted by a digital ID. Digital ID encryption is based on the S/MIME
encryption using a public key for encryption and private key for decryption. Compared to S/MIME, the digital ID will only secure the attachment,
which also allows using this transmission process for other transmission
types than email. In addition to digital ID stored on the MFP, certificates
and/or public keys stored on the LDAP server can be used.
This screen shot is an example of a PDF document that has been signed
with a digital ID. The signature information shows that this document has
been altered since its creation and is no longer valid/trustworthy.
Manual Destination Blocking

This illustration shows the encryption process via digital ID.
PDF Digital Signature
To prevent tampering with MFP-created PDF documents, it is possible
to add a digital signature. The digital signature is based on the SSL
certificate installed on, or used by, the MFP.
The certificate information will be added to the PDF file without encryption.
However, changes to the PDF after creation (e.g. changing text, adding or
deleting items) will be recorded in the PDF security information which is
available in the PDF reading applications.
In addition to preventing documents from being tampered with, the PDF
signature gives information about the source of the document, helping the
program to recognize invalid document sources.
The selection of manual destination blocking will prevent the direct input
of, for example, email addresses for transmission of scan files from the
MFP. If it is set to “on”, the user only has the possibility to use destinations
stored on the MFP, on the PageScope Enterprise Server or a local email
database available via LDAP search.
In addition to preventing the direct input of destinations, the user can be
blocked from changing the FROM address for an email transmission. If
the machine is set to authentication, the user’s email address stored in
the authentication data or Active Directory will automatically be used.
Address Book Access Control
The destinations (e.g. email, SMB, FTP) stored in the MFP or PageScope
Enterprise Suite address book can be set with an access level. These
levels control the access/visibility of destinations for the user, depending
on their security level as given in the authentication data. Possible levels
are 0–5.

Additional Security Functions
MFP Audit Logs
Many Konica Minolta bizhub systems contain electronic job logs that
record all print, copy, scan and fax jobs sent to or from the MFP. For
example, the bizhub MFP Audit Log records all print jobs sent by named
users. The Audit Log records when the job was printed, how many copies,
the time it was printed, etc.

bizhub SECURE is a value added service that
Konica Minolta provides on behalf of our clients
who do not have the infrastructure or bandwidth
to enable and configure the hard drive protection
functions detailed in this white paper.

Federal Information Processing Standard (FIPS)
Publication 140-2
The Federal Information Processing Standard (FIPS) Publication 1402, is a U.S. government computer security standard used to accredit
cryptographic modules. It is a benchmark that describes US Federal
government requirements that IT products should meet for sensitive, but
unclassified use. The criteria was published by the National Institute of
Standards and Technology (NIST). It is administered under the umbrella of
the Cryptographic Module Validation Programme (CMVP).
The certification ensures that the cryptographic modules contained in
bizhub MFP’s are the highest levels and meet US Government Regulatory
compliance. Konica Minolta is one of the only MFP manufacturers who
has obtained FIPS 140-2 certification for their products.
• Scan Destination
• Number of Pages
In addition, Konica Minolta now includes a new built-in audit trail security
feature in bizhub OP devices called the Image Log Transfer function. With
the Image Log Transfer function, you can transfer the image using the
Scan-to-FTP or WebDAV process to a registered server at the same time
that the device is reading an image in copy mode, reading an image in
scan mode, processing a print or image input for FAX RX (reception).
With this setting enabled all documents, whether electronic originals
or paper originals are converted to PDF and sent automatically to a
registered external server. Here is an example of a scanned job captured
and sent to the external log server:
Encryption and the authentication function has been attained by the using
the standard embedded Encryption modules, such as OpenSSL/MES (RSA
BSAFE Micro Edition Suite).
The following encryption functions are FIPS 140-2 certified on the latest
bizhub office models.
1. E ncrypted communication at the time of sending scanned data
from the bizhub MFP
• Scan to WebDav over SSL
• Scan to WebDav function is encrypted by using SSL

• Scan to email encryption
• At the time of S/MIME transmission of Scan to Email from the MFP
2. PDF encryption file generating function
• The MFP can encrypt the scanned PDF image prior to transmitting
the file as an email attachment or to a shared folder. The PDF
encryption is FIP 140-2 certified.
On the next page is an example of the registered location and the two
files that are automatically routed to the external server. The text
document is the log file, which is associated with the individual pdf
image file of the scanned document.

Unauthorized Access Lock
Like a cash terminal, the MFP can be set to reject a user if they attempt
to authenticate with the wrong password. The MFP administrator has the
choice of two modes to lock the machine:
The unauthorized access lock can be extended to the system user box for
confidential documents (secure print box).
The same modes will be applied in the case of unauthorized access to
this document storage location.
Mode 1
The machine lock-out will be released after a certain
time (1–60 minutes)
Mode 2
In addition to mode 1, the number of wrong attempts
can be specified (1–5)
Distribution Number Printing
To index a certain number of printouts, it is possible to print a distribution
number on every handout (first page or all pages). This allows the easy
identification of illegal copies made of this limited issue of documents.
All copies, prints and scans created on the MFP can be marked with
a watermark or overlay image. This enables easy and highly visible
classification of the document security level. The stamping of the different
document types can be set as default by the administrator or individually
as required by the user.
Service Mode/Administrator Mode Protection
The service mode and the administrator mode are protected by passwords or by codes. The service mode is only accessible via a special code
that is only known to Konica Minolta certified engineers.
The administrator mode is protected by an eight-digit alphanumeric
password. This password can only be changed by the service engineer or
in the administration mode itself. This avoids any changes to passwords,
destinations or other security-related functions being made by unauthorized users.
This is an example of the MFP watermark settings (bizhub C654).
Copy Protection via Watermark
This function adds an invisible pattern to the original printed document.
When the original document is copied, the message pattern (e.g. “Copy”)
comes up, and clearly distinguishes the copied document from the
original one.
This image shows the administrator login screen on the MFP panel
(bizhub C654).

In addition to the message, the MFP serial number, as well as the date
and time the copy was made, can be set for the pattern. The combination
of the information in the pattern and the audit log helps to trace the
person who made the illegal copy.
These are examples of the MFP copy security settings (bizhub C654).
Copy Guard Function/Password Copy Function
Fax Rerouting
Many of the Konica Minolta devices could be equipped with a security kit
which offers the Copy Guard and Password Copy functions.
Usually, incoming fax documents are immediately printed by a fax or
MFP device. This enables anyone to view the fax document in the output
tray. To prevent all unauthorized access to arriving fax documents, it is
possible to reroute incoming faxes to a secure location. This could be
any destination stored in the MFP address book (email, SMB, FTP or user
box). The user box is particularly suited as a destination for confidential
fax receipt, and can digitally receive incoming faxes with an F-Code.
Besides the fact that digital fax receipt can speed up the fax reception
process in general, it completely prevents unauthorized access to fax
information, confidential or not.
These functions allow administrators to embed a security pattern on
the output. If a user tries to make a secondary copy of the output, the
device will display a message that says “Copying Prohibited” and will
prohibit copying. The password copy function allows administrators to set
a password so the document can only be copied if the user enters the
correct password.
