You can configure the Email Security appliance to display a message called a “login banner” when a user<br />

attempts to log into the appliance through SSH, Telnet, FTP, or Web UI. The login banner is<br />

customizable text that appears above the login prompt in the CLI and to the right of the login prompt in<br />

the GUI. You can use the login banner to display internal security information or best practice<br />

instructions for the appliance. For example, you can create a simple note that saying that unauthorized<br />

use of the appliance is prohibited or a detailed warning concerning the organization’s right to review<br />

changes made by the user to the appliance.<br />

Use the adminaccessconfig > banner command in the CLI to create the login banner. The maximum<br />

length of the login banner is 2000 characters to fit 80x25 consoles. A login banner can be imported from<br />

a file in the /data/pub/configuration directory on the appliance. After creating the banner, commit<br />

your changes.<br />

To set the System Time on your Cisco <strong>IronPort</strong> appliance, set the Time Zone used, or select an NTP<br />

server and query interface, use the Time Zone or Time Settings page from the System Administration<br />

menu in the GUI or use the following commands in the CLI: ntpconfig, settime, and settz.<br />

You can also verify the time zone files used by <strong>AsyncOS</strong> on the System Administration > Time Settings<br />

page or using the tzupdate CLI command.<br />

The Time Zone page (available via the System Administration menu in the GUI) displays the time zone<br />

for your Cisco <strong>IronPort</strong> appliance. You can select a specific time zone or GMT offset.<br />

Step 1 Click Edit Settings on the System Administration > Time Zone page. The Edit Time Zone page is<br />
