=====Description=====
Setting the boot loader password will require that anyone rebooting the system must enter a password before being able to set command line boot parameters.

=====Audit=====
Run the following commands and verify output matches:
# grep "^set superusers" /boot/grub/grub.cfg
set superusers=""
# grep "^password" /boot/grub/grub.cfg
password_pbkdf2

# grub-mkpasswd-pbkdf2
Enter password:

# update-grub
