Check Text (C-65033r996383_chk)

Verify all SLEM 5 files and directories on the system have a valid group with the following command:

Note: The value after -fstype must be replaced with the filesystem type. XFS is used as an example.

> sudo find / -fstype xfs -nogroup

If any files on the system do not have a valid group, this is a finding.

Fix Text (F-64941r995778_fix)

Either remove all files and directories from SLEM 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>
