Encrypting Communications

Encrypt networks communications using SSL (Secure Sockets Layer). This function is useful for establishing secure connections and protecting communications from alterations and interceptions.

A: Prohibits spoofing

B: Prohibits tampering

C: Prohibits interception

There are 3 system SSL settings, listed here in order of least secure to most secure.

1. Using the system's default certificate

2. Using a certificate created on the system

3. Using a certificate provided by a CA (Certificate Authority) upon request

This section shows the creation of a certificate on the machine while logged in to Web Connection as the administrator.

Log in to Web Connection on the Image Controller as an administrator to configure the Image Controller SSL settings and perform setting using the procedure same as this system.
