Protection Using Encryption

When you access the machine using a Web browser or IPP, you can establish en-
crypted communication using SSL. When you access the machine using an ap-
plication such as SmartDeviceMonitor for Admin, you can establish encrypted
communication using SNMPv3 or SSL.
To protect data from interception, analysis, and tampering, you can install a
server certificate in the machine, negotiate a secure connection, and encrypt
transmitted data.
