• Documents in mailboxes
• Address book data
Important
Be sure to save all necessary settings and documents before starting to use the
data encryption feature or changing the settings. An error will occur if the connected
hard disk does not match the encryption settings.
1.6. 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.
• 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 need to set their passcode and encryption key based on
the following rules:
- Set a passcode containing both numeric and alphabetic characters.
- Do not set a passcode consisting of a string of characters that can be easily
guessed.
• 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 same settings are required as the machine’s configuration described as
follows:
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、recommended browser is Microsoft internet Explorer 6/7、Netscape
7.x、Mozilla Firefox 2.x/3.x)
2. S/MIME
Set the machine and mail clients as following Shared Key/hash function.
・RC2(128bit)/SHA1
・3Key Triple-DES(168bit)/SHA1
3. IPSec
Set the IPSec host that communicate with the machine as following Shared
Key/hash function.
・AES(128bit)/SHA1
・3Key Triple-DES(168bit)/SHA1
4. SNMPv3
Shared key encrypt system of SNMPv3 is DES fixed. Hash function is select to
SHA1.
