All AIX files and directories must have a valid group owner.

Failure to restrict system access to authenticated users negatively impacts operating system security.

Determine if any file on the system does not have a valid group owner using command: # find / -nogroup -print

If any such files are found, this is a finding.

Change the group owner for each file without a valid group owner using command: # chgrp <a-valid-group> /tmp/a-file-without-a-valid-group-owner
