FireEye Cheat Sheet

Maintaining FireEye NX Appliances:

First it is highly recommended you remove retired guest images so you can backup your appliance.

• guest-images purge retired-version

Then backup the appliance. You can back up locally or to a remote location. If you don't need to keep the events you can just do a basic config backup and not the fedb. Two ways to do it... via web or cli... I will show you from commandline. Remove  +fedb to just backup your config.

• backup profile full to local prefix NXAPPLIANCENAME - Full local backup
• backup profile config+fedb to scp://UID:PASS@BACKUPSERVE/ - Remote config and fedb backup

Make sure content updates are occurring.
If you have a CMS make sure your NX is connected to it.

Rotate your password regularly. 60-90 days.
