Adding a Login Banner
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.
