Banner

You can configure messages to show users when they connect to the device command line interface (CLI).

Procedure

1

Choose Devices > Platform Settings and create or edit the Firewall Threat Defense policy.

2

Select Banner.

3

Configure the banner.

Following are some tips and requirements for banners.

  • Only ASCII characters are allowed. You can use line returns (press Enter), but you cannot use tabs.

  • You can dynamically add the hostname or domain name of the device by including the variables $(hostname) or $(domain) .

  • Although there is no absolute length restriction on banners, Telnet or SSH sessions will close if there is not enough system memory available to process the banner messages.

  • From a security perspective, it is important that your banner discourage unauthorized access. Do not use the words "welcome" or "please," as they appear to invite intruders in. The following banner sets the correct tone for unauthorized access: 

    
You have logged in to a secure device. 
If you are not authorized to access this device, 
log out immediately or risk criminal charges.

Click Save.

You can now go to Deploy > Deployment and deploy the policy to assigned devices. The changes are not active until you deploy them.
