Set the owner and group of your boot loaders config file to the root user. These instructions default to GRUB stored at /boot/grub/grub.cfg.
Rationale:
Setting the owner and group to root prevents non-root users from changing the file.
Parameter:
[0, perm_600]
Technical Mechanism:
Run the following to change ownership of /boot/grub/grub.cfg:
# chown root:root /boot/grub/grub.cfg
