1.4.1 Ensure bootloader password is set


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.

Requiring a boot password upon execution of the boot loader will prevent an unauthorized user from entering boot parameters or changing the boot partition. This prevents users from weakening security (e.g. turning off SELinux at boot time).


Create an encrypted password with grub2-setpassword :

# grub2-setpassword

Enter password: <password>
Confirm password: <password>


If password protection is enabled, only the designated superuser can edit a Grub 2 menu item by pressing "e" or access the GRUB 2 command line by pressing "c"

If GRUB 2 is set up to boot automatically to a password-protected menu entry the user has no option to back out of the password prompt to select another menu entry. Holding the SHIFT key will not display the menu in this case. The user must enter the correct username and password. If unable, the configuration files will have to be edited via the LiveCD or other means to fix the problem
