Configure AIDE

Edit /etc/aide/aide.conf. Enable the following options:

report_summarize_changes=true

Initialize the database

sudo aide --config /etc/aide/aide.conf --init

AIDE will indicate the location of the new database when it finishes:

New AIDE database written to /var/lib/aide/aide.db.new

Rename the file:

sudo mv /var/lib/aide/aide.db.new /var/lib/aide/aide.db

Trigger a check

sudo aide --check --config /etc/aide/aide.conf

Crontab

0 3 * * * aide --check --config /etc/aide/aide.conf

Update

Run AIDE after editing system files and install system updates or new packages so that AIDE can update their checksums in the AIDE database. This will help prevent false positives.

sudo aide --update --config /etc/aide/aide.conf
