Check Text ( C-19382r376718_chk )
To check the ownership of "/boot/grub/grub.conf", run the command:

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

If properly configured, the output should indicate that the owner is "root".
If it does not, this is a finding.
Fix Text (F-19380r376719_fix)
The file "/boot/grub/grub.conf" should be owned by the "root" user to prevent destruction or modification of the file. To properly set the owner of "/boot/grub/grub.conf", run the command:

# chown root /boot/grub/grub.conf
