Fix Recommendation

Install AIDE, initialize it, and perform a manual check.

Install AIDE:
$ sudo zipper in aide

Initialize it (this may take a few minutes):
$ sudo aide -i

The new database will need to be renamed to be read by AIDE:
$ sudo mv /var/lib/aide/aide.db.new /var/lib/aide/aide.db

Perform a manual check:
$ sudo aide --check

Example output:
Summary:
Total number of files: 140621
Added files: 1
Removed files: 1
Changed files: 0

Done.

Check Contents

Verify that Advanced Intrusion Detection Environment (AIDE) is installed and verifies the correct operation of all security functions.

Check that the AIDE package is installed with the following command:
$ sudo zypper if aide | grep "Installed"
Installed: Yes

If AIDE is not installed, ask the System Administrator 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 aide --check

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