Fix Recommendation

Configure the file integrity tool to check file and directory ACLs.

If AIDE is installed, ensure the "acl" rule is present on all uncommented file and directory selection lists.

Check Contents

Verify that that AIDE is verifying ACLs with the following command:

$ grep acl /etc/aide.conf

All= p+i+n+u+g+s+m+S+sha512+acl+xattrs+selinux

If the "acl" rule is not being used on all uncommented selection lines in the "/etc/aide.conf" file, or ACLs are not being checked by another file integrity tool, this is a finding.
