Limiting Available Functions
To prevent unauthorized operation, you can specify who is allowed to access each of the machine's
functions. For details about limiting available functions for users and groups, see p.122 "Limiting
Available Functions".
Enhancing Network Security
Preventing Unauthorized Access
You can limit IP addresses or disable ports to prevent unauthorized access over the network and
protect the Address Book, stored files, and default settings. For details about preventing unauthorized
access, see p.145 "Preventing Unauthorized Access".
Encrypting Transmitted Passwords
We recommend you use one or more of the following security protocols: IPsec, SNMPv3, and SSL.
Using these protocols can enhance your machine's security by making login passwords harder to
break.
Also, encrypt the login password for administrator authentication and user authentication. For details
about encrypting transmitted passwords, see p.155 "Encrypting Transmitted Passwords".
Safer Communication Using SSL, SNMPv3 and IPsec
You can encrypt this machine's transmissions using SSL, SNMPv3, and IPsec. By encrypting transmitted
data and safeguarding the transmission route, you can prevent sent data from being intercepted,
analyzed, and tampered with. For details about safer communication using SSL, SNMPv3 and IPsec,
see p.157 "Protection Using Encryption" and p.166 "Transmission Using IPsec".
