This document describes how to create and customize banners to login screens into the AlienVault USM Appliance Servers.
To show a banner each time someone tries to connect through ssh to USM Appliance , you need to modify the ssh configuration file by following the steps below:
- Edit the ssh config file: /etc/ssh/sshd_config
Add the configuration needed to load a banner from a given file, for example: Banner /etc/ssh_banner
Set the text needed to be showed as ssh banner, for example:
- Restart ssh service:
USM:/# /etc/init.d/ssh restart
[ ok ] Restarting OpenBSD Secure Shell server: sshd.
If you need to configure a banner to show when an user is logging in through the console (physical or VMWare), you need to modify the /etc/issue file. By default /etc/issue contains a message showing the USM Appliance version, but you can customize:
Web Interface Banner
And for the web interface, you need to modify the /usr/share/ossim/www/session/login.php file in order to show a custom banner or text in your USM Appliance web UI login.
Note: Custom files would be overwritten in the updates; check your custom files after each update to verify that they were not modified.
