My notes, things I have learned, and documentation I have created.

To update an AIDE database:

To check the filesystem against the current AIDE database:
aide –check

Modify the /etc/aide.conf configuration file with any changes.

Put new AIDE database into use:
cd /var/lib/aide
cp -p aide.db.new.gz aide.db.gz

Run check again to see if changes provide the expected result.
aide –check
