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 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 passcodes.
・ Passcodes have to contain both numeric and alphabetic.
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
following data encryption suite
・
S SL_RSA_WITH_RC4_128_SHA
・
S SL_RSA_WITH_3DES_EDE_CBC_SHA
T LS_RSA_WITH_AES_128_CBC_SHA
・
T LS_RSA_WITH_AES_256_CBC_SHA
・
（
S pecifically, 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 Encryption Method/Message Digest Algorithm.
・
R C2(128bit)/SHA1
・
3 Key Triple-DES(168bit)/SHA1
3. IPSec
Set the IPSec host that communicates with the machine as following Encryption
Method/Message Digest Algorithm.
A ES(128bit)/SHA1
・
・
3 Key Triple-DES(168bit)/SHA1
4. SNMPv3
Encryption Method of SNMPv3 is DES fixed. Set the Message Digest Algorithm to SHA1.
Important:
For secure operation, while you are using the CentreWare Internet Services, please do not access other
web site.
