Displaying Messages to Administrative Users

Displaying a Message Before Login

You can configure the Email Security appliance to display a message before a user attempts to log into
the appliance through SSH, FTP, or the Web UI. The login banner is customizable text that appears above
the login prompt. 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.

Use the

adminaccessconfig > banner

command in the CLI to create the login banner. 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.

Displaying a Message After Login

You can configure AsyncOS for Email to display a welcome banner after a user successfully logs into
the appliance through SSH, FTP, or the Web UI. You can use the welcome banner to display internal
security information or best practice instructions for the appliance.

Use the

adminaccessconfig

welcome

command in CLI to create the welcome banner. The maximum

length of the welcome banner is 1600 characters.

You can import a welcome banner from a file in the

/data/pub/configuration

directory on your

appliance. After creating the banner, commit your changes.
