Cisco Cisco Email Security Appliance C370D Technical References

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:

- RESTRICT - Specify IP addresses/Subnets/Ranges to be allowed access.
