Set User/Group Owner on bootloader config (Scored)
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.
Parameter:
[enable/disable]
Technical Mechanism:
Setting the owner and group to root prevents non-root users from changing the file.
Fix:
Run the following to change ownership of /boot/grub/grub.cfg:
# chown root:root /boot/grub/grub.cfg
