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 2-5.
Setting the Enhanced Security Mode to [ON] will enhance the authentication function. Access control is then
provided through password authentication for any access to the Administrator Settings, User Authentication
mode, and Secured Job file. Access is thereby granted only to the authenticated user.
A password that can be set must meet the requirements of the Password Rules. The machine does not ac-
cept setting of an easily decipherable password. For details of the Password Rules, see page 1-9.
If a wrong password has been entered three cumulative times during password authentication, the machine
determines that it is unauthorized access through Prohibited Functions When Authentication Error, prohibit-
ing any further entry of the password. By prohibiting the password entry operation, the machine prevents un-
authorized use or removal of data, thereby ensuring secured used of the machine. This function is not,
however, governed by authentication by the ISO15408.
When the machine is to be discarded, or use of a leased machine is terminated at the end of the leasing con-
tract, the data erase function overwrites and erases all data stored in all spaces of the HDD. The function also
resets all passwords saved in the memory area on the MFP board to factory settings, preventing leak of data.
For details of items to be cleared by data erase function, see page 1-11.
Check Count Clear Conditions
The following are the conditions for clearing or resetting the check count of the number of wrong entries at
the time of authentication.
NOTICE
The check count is cleared or reset by restarting the machine. If there is any user who frequently turns ON
and OFF the machine, warn him or her of the fact or take necessary steps.
<Administrator Settings>
-Authentication of Administrator Settings is successful.
-The machine is restarted
<User Authentication Mode>
-User Authentication mode is successful.
-The machine is restarted

1.3 Data to be Protected 1
1.3 Data to be Protected
The underlying concept of this machine toward security is "to protect data that can be disclosed against the
intention of users."
The following types of image files that have been stored in the machine and made available for use by its
users are protected while the machine is being used.
-Image files stored in the HDD by Secured Job
-Image files stored as "Personal" in the HDD by Scan to HDD
-Image files stored in the HDD by ID & Print
-Image files sent by an E-mail
The following data are also counted among the assets to be protected:
-Password
– User passwords and Secured Job passwords stored in the HDD, and Administrator passwords and
SNMP passwords stored in the memory area on the MFP board
-Encryption Key
– Encryption Key to be registered in the memory area on the MFP board
-User identification information
– User identification information stored in the HDD
-IC card information
– User IC card information stored in the HDD
-Trusted channel setting data
– Trusted channel setting data stored in the memory area on the MFP board
-External server identification setting data

-Destination recipient data
– Data including E-mail addresses and telephone numbers, serving as data identifying the recipients to
which the image registered in the HDD is sent
-S/MIME certificate data
– Certificate data registered in the HDD and used when the image is sent by E-mail
The following types of data stored in the HDD and memory area on the MFP board are protected when use
of a leased machine is terminated at the end of the leasing contract, the machine is to be discarded.
-Image files stored in the HDD by Secured Job
-Image files stored as "Personal" in the HDD by Scan to HDD
-Image files stored in the HDD by ID & Print
-Image files of a job in the queue
-Any image files stored in the HDD data space other than the Secured Job files, files stored as "Personal"
by Scan to HDD, and ID & Print files.
-Data files left in the HDD data space, used as image files and not deleted through the general deletion
operation
-Temporary data files generated during print image file processing
-Destination recipient data (e-mail address, telephone number)
-S/MIME certificate data
-Administrator passwords, SNMP passwords, Encryption Key, trusted channel setting data, and ma-
chine setting data stored in the memory area on the MFP board
-User identification information, user IC card information, User passwords, Secured Job passwords, and
external server identification setting data stored in the HDD
This machine offers the SSL function as a data protection method to ensure confidentiality of images (Scan
to HDD files) transmitted and received over the network.
When transmitting and receiving highly confidential image data (Secured Job files, Scan to HDD files, ID &
Print files, Image files sent by an E-mail) among different pieces of IT equipment within an office LAN, the
machine carries out communications with the correct destination via reliable paths or through anti-sniffing
measures, assuming an office environment that responds to most stringent security requirements.
NOTICE
Secured Job files and ID & Print files transmitted from the client PC to the machine are not encrypted. To
protect the Secured Job files and ID & Print files, take necessary anti-sniffing measures, including installation
of cryptographic communications equipment or a sniffing detector.

following conditions.
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.
<To Achieve Effective Security>
-A single individual 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 an SMTP server (mail server), a DNS server, a user information control system, or a WebDAV
server is to be used, the Administrator of the machine should periodically check that the corresponding
administrator of the server appropriately manages the server to allow no settings to be changed without
permission.
Password Usage Requirements
The Administrator must control the Administrator Password, auth-password, and priv-password appropriate-
ly 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 Secured Job 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 knows the Administrator Password, auth-password,
and priv-password.
-The Administrator must change the Administrator Password, auth-password, and priv-password at
regular intervals.
-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 Administrator Password, auth-password,
and priv-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 should
change the Administrator Password as soon as possible.
-The Administrator should have users ensure that the passwords set for the User Authentication and Se-
cured Job 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 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 Secured Job.
-Upon change of the Administrators, the old Administrator of the machine should promptly have the new
one change the Administrator password.
Network Connection Requirements for the Machine
