7장. Checking integrity with AIDE

Procedure

1. Install the aide package:

   # dnf install aide

2. Generate an initial database:

   # aide --init
   Start timestamp: 2024-07-08 10:39:23 -0400 (AIDE 0.16)
   AIDE initialized database at /var/lib/aide/aide.db.new.gz
   
   Number of entries:	55856
   
   ---------------------------------------------------
   The attributes of the (uncompressed) database(s):
   ---------------------------------------------------
   
   /var/lib/aide/aide.db.new.gz
   …
     SHA512   : mZaWoGzL2m6ZcyyZ/AXTIowliEXWSZqx
                IFYImY4f7id4u+Bq8WeuSE2jasZur/A4
                FPBFaBkoCFHdoE/FW/V94Q==

3. Optional: In the default configuration, the aide --init command checks just a set of directories and files defined in the /etc/aide.conf file. To include additional directories or files in the AIDE database, and to change their watched parameters, edit /etc/aide.conf accordingly.

4. To start using the database, remove the .new substring from the initial database file name:

   # mv /var/lib/aide/aide.db.new.gz /var/lib/aide/aide.db.gz

5. Optional: To change the location of the AIDE database, edit the /etc/aide.conf file and modify the DBDIR value. For additional security, store the database, configuration, and the /usr/sbin/aide binary file in a secure location such as a read-only media.
