Users and administrators need to set passcode and an encryption key according to the
following rules for the client PC login and the machine’s setup.
- Do not use an easily guessed character strings passcode.
- A passcode needs to contain both numeric and alphabetic characters.
z
Administrators need 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.
z
Users and administrators need to manage and operate the machine so that their user IDs
and passcodes may not be disclosed to another person.
z
The users need to set a user ID and a passcode certainly on [Accounting Configuration] of
printer driver.
z
For secure operation, all of the remote trusted IT products that communicate with the
machine shall implement the communication protocol in accordance with industry
standard practice with respect to RFC/other standard compliance (SSL/TLS, IPSec, SNMP
v3, S/MIME) and shall work as advertised.
SSL/TLS
For the SSL client (Web browser) and the SSL server that communicate with the machine,
select a data encryption suite from the following.
z
SSL_RSA_WITH_RC4_128_SHA
z
SSL_RSA_WITH_3DES_EDE_CBC_SHA
z
TLS_RSA_WITH_AES_128_CBC_SHA
z
TLS_RSA_WITH_AES_256_CBC_SHA
z
TLS_RSA_WITH_AES_128_CBC_SHA256
z
TLS_RSA_WITH_AES_256_CBC_SHA256
(The recommended browser is Microsoft
®
Internet Explorer
®
7/8/9/10)
S/MIME
For the machine and E-mail clients, select an Encryption Method/Message Digest Algorithm
from the following.
z
3Key Triple-DES/168bit, AES/128bit, AES/192bit, AES/256bit
z
SHA1, SHA256
IPSec
For the IPSec host that communicates with the machine, select an Encryption Method/
Message Digest Algorithm from the following.
z
AES(128bit)/SHA1
z
3Key Triple-DES(168bit)/SHA1
