For Optimal Performance of the Security
features
The manager (of the organization that the machine is used for) needs to follow the instructions below:
• Assign appropriate persons as system and machine administrators, and manage and train them properly.
• The manager and system administrators have to train users about the security policies and procedures of their
organization.
• The machine have to be placed in a secure or monitored area that provides protection from unmanaged
physical access to the machine.
• If the network where the machine is installed is to be connected to external networks, configure the network
properly to block any unauthorized external access.
• The users have to set a user ID and a passcode certainly on accounting configuration of printer driver.
• Users and administrators have to set passcodes and encryption key according to the following rule for the
client PC login and the machine’s setup.
・ Do not use an easily guessed character strings passcode.
・ A passcode has to contain both numeric and alphabetic characters.
• Users and administrators have to manage and operate it so that own user ID and passcode may not be
disclosed to another person.
• Administrators have to set the account policy in the remote authentication server as follows.
・ Set password policy to [9 or more characters]
・ Set account lockout policy to [5 times]
• For secure operation, all of the remote trusted IT products that communicate with the machine implement the
communication protocol in accordance with industry standard practice with respect to RFC/other standard
compliance (SSL/TLS, IPSec, SNMPv3, S/MIME ) and work as advertised.
• The settings described below are required same as the machine’s configuration.
1.) SSL/TLS
Set the SSL client (WEB browser) and SSL server that communicate with the machine as following data
encryption suite
・ SSL_RSA_WITH_RC4_128_SHA
・ SSL_RSA_WITH_3DES_EDE_CBC_SHA
・ TLS_RSA_WITH_AES_128_CBC_SHA
・ TLS_RSA_WITH_AES_256_CBC_SHA
(Specifically, the recommended browser is Microsoft internet Explorer 6/7/8, Mozilla Firefox 2.x/3.x )
2.) S/MIME
Set the machine and E-mail clients as following Encryption Method/Message Digest Algorithm.
・ RC2 (128bit )/SHA1
・ 3Key Triple-DES (168bit )/SHA1
