Dell C7765dn Supplementary Manual page 8

• If the machine is on the internal network that connects to external networks,
configure the network properly to block any unauthorized external access.
• Set passcode and encryption key according to the following rules.
- Do not use an easily guessable passcode.
- A passcode needs to contain both numeric and alphabetic characters.
• Administrators need to set the account policies on the remote authentication
server as follows.
- Set password policy to 9 or more characters.
- Set account lockout policy to 5 times.
• Users need to set a user ID and a passcode in [Accounting Configuration] via the
printer driver.
• For secure operation, all of the remote trusted IT products that communicate with
the machine must 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 must 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:
• 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
• TLS_RSA_WITH_AES_128_CBC_SHA256
• TLS_RSA_WITH_AES_256_CBC_SHA256
(The recommended browser is Microsoft
S/MIME
For the machine and E-mail clients, select an Encryption Method/Message Digest
Algorithm from the following:
• 3Key Triple-DES/168bit, AES/128bit, AES/192bit, AES/256bit
• SHA1, SHA256
IPSec
For the IPSec host that communicates with the machine, select an Encryption
Method/ Message Digest Algorithm from the following:
• AES(128bit)/SHA1
• 3Key Triple-DES(168bit)/SHA1
SNMP v3
The encryption method of SNMPv3 is DES/56bit or AES 128bit. Set [Message Digest
Algorithm] to [SHA1].
