Cisco Cisco Email Security Appliance C170 Referências técnicas

Example - Configuring Network Access List

You can configure the Email Security appliance to display a message called a “login banner” when a user 
attempts to log into the appliance through SSH, Telnet, FTP, or Web UI. The login banner is 
customizable text that appears above the login prompt in the CLI and to the right of the login prompt in 
the GUI. You can use the login banner to display internal security information or best practice 
instructions for the appliance. For example, you can create a simple note that saying that unauthorized 
use of the appliance is prohibited or a detailed warning concerning the organization’s right to review 
changes made by the user to the appliance.

The maximum length of the login banner is 2000 characters to fit 80x25 consoles. A login banner can 
be imported from a file in the 

/data/pub/configuration

 directory on the appliance. After creating the 

banner, commit your changes.

In the following example, the login banner “Use of this system in an unauthorized manner is prohibited” 
is added to the appliance:
