Check Text (C-269239r1050121_chk)
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.
Fix Text (F-73171r1048094_fix)
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.
