OL08-00-010150 - OL 8 operating systems booted with a BIOS must require authentication upon booting into single-user and maintenance modes.


If the system does not require valid authentication before it boots into single-user or maintenance mode, anyone who invokes single-user or maintenance mode is granted privileged access to all files on the system. GRUB 2 is the default boot loader for OL 8 and is designed to require a password to boot into single-user mode or modify the boot menu.


Configure the system to require a grub bootloader password for the grub superusers account with the grub2-setpassword command, which creates/overwrites the '/boot/grub2/user.cfg' file.

Generate an encrypted grub2 password for the grub superusers account with the following command:

$ sudo grub2-setpassword
Enter password:
Confirm password:
