Fix Recommendation

For any log file that contains ACLs, run the following command:

/usr/bin/sudo chmod -N [audit log file]

Check Contents

To check if a log file contains ACLs, run the following commands:

/usr/bin/sudo ls -le $(/usr/bin/sudo /usr/bin/grep '^dir' /etc/security/audit_control | awk -F: '{print $2}') | /usr/bin/grep -v current

In the output from the above commands, ACLs will be listed under any file that may contain them (e.g., "0: group:admin allow list,readattr,reaadextattr,readsecurity").

If any such line exists, this is a finding.
