Discussion

Files without a valid group owner may be unintentionally inherited if a group is assigned the same Group Identifier (GID) as the GID of the files without a valid group owner.

Check Content

Verify all files and directories on OL 8 have a valid group with the following command: 
 
$ sudo find / -nogroup 
 
If any files on the system do not have an assigned group, this is a finding.

Fix Text

Either remove all files and directories from OL 8 that do not have a valid group, or assign a valid group to all files and directories on the system with the "chgrp" command: 
 
$ sudo chgrp <group> <file>
