Fix Recommendation

Configure Amazon Linux 2023 to have the AIDE package installed.

Install AIDE:

$ sudo dnf install -y aide

Initialize AIDE:

$ sudo /usr/sbin/aide --init

The new database must be renamed to be read by AIDE:

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

Perform a manual check:

$ sudo /usr/sbin/aide --check
Example output:

2023-06-05 10:16:08 -0600 (AIDE 0.16)
AIDE found NO differences between database and filesystem. Looks okay!!

Check Contents

Verify Amazon Linux 2023 has the AIDE package installed with the following command:

$ dnf list --installed aide
Installed Packages
aide.x86_64 0.18.6-1.amzn2023.0.1 @amazonlinux

If AIDE is not installed, ask the system administrator (SA) how file integrity checks are performed on the system.

If there is no application installed to perform integrity checks, this is a finding.

If AIDE is installed, check if it has been initialized with the following command:

$ sudo /usr/sbin/aide --check

If the output is "Couldn't open file /var/lib/aide/aide.db.gz for reading", this is a finding.
