The "root" group is a highly-privileged group. Furthermore, the group-owner of this file should not have any access privileges anyway.

Check Text ( C-19383r376721_chk )
To check the group ownership of "/boot/grub/grub.conf", run the command:

$ ls -lL /boot/grub/grub.conf

If properly configured, the output should indicate the group-owner is "root".
If it does not, this is a finding.
Fix Text (F-19381r376722_fix)
The file "/boot/grub/grub.conf" should be group-owned by the "root" group to prevent destruction or modification of the file. To properly set the group owner of "/boot/grub/grub.conf", run the command:

# chgrp root /boot/grub/grub.conf
