Check Text ( C-53393r3_chk )
To check the permissions of "/boot/grub/grub.conf", run the command: $ sudo ls -lL /boot/grub/grub.conf If properly configured, the output should indicate the following permissions: "-rw-------" If it does not, this is a finding.

Fix Text (F-55743r3_fix)
File permissions for "/boot/grub/grub.conf" should be set to 600, which is the default. To properly set the permissions of "/boot/grub/grub.conf", run the command: # chmod 600 /boot/grub/grub.conf Boot partitions based on VFAT, NTFS, or other non-standard configurations may require alternative measures.
