Check Text (C-282670r1200990_chk)
Verify all local files and directories on TOSS 5 have a valid group using the following command:
$ df --local -P | awk {'if (NR!=1) print $6'} | sudo xargs -I '{}' find '{}' -xdev -nogroup
If any files on the system do not have an assigned group, this is a finding.
Fix Text (F-87136r1200989_fix)
Either remove all files and directories from TOSS 5 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>
