AIDE - Build, Store, and Test Database
Generate a new database:
# /usr/sbin/aide –init
By default, the database will be written to the file /var/lib/aide/aide.db.new.gz.
The database, as well as the configuration file /etc/aide.conf and the binary /usr/sbin/aide (or hashes of these files) should be copied and stored in a secure location. Storing these copies or hashes on read-only media may provide further confidence that they will not be altered.
Install the newly-generated database:
# cp /var/lib/aide/aide.db.new.gz /var/lib/aide/aide.db.gz
Run a manual check:
# /usr/sbin/aide –check
If this check produces any unexpected output, investigate.
