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
