The system must require authentication before allowing modification of the boot devices or menus. Secure the GRUB Menu (Intel).

Description
The flexibility that GRUB provides creates a security risk if its configuration is modified by an unauthorized user. The failsafe menu entry needs to be secured in the same environments that require securing the systems firmware to avoid unauthorized removable media boots.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-216218r959010_chk)

This check applies to X86 systems only. This check applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global", this check applies. # grep source /rpool/boot/grub/grub.cfg source $prefix/custom.cfg If the output does not contain "source $prefix/custom.cfg" on a line of its own, this is a finding. # grep superusers /rpool/boot/grub/custom.cfg. # grep password_pbkdf2 /rpool/boot/grub/custom.cfg If no superuser name and password are defined, this is a finding.

Fix Text (F-17454r373037_fix)

The root role is required. This action applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global", this action applies. Update GRUB to use a custom configuration file. # pfedit /rpool/boot/grub/grub.cfg Insert the line: source $prefix/custom.cfg Create a password hash. # /usr/lib/grub2/bios/bin/grub-mkpasswd-pbkdf2 Enter password: Reenter password: Your PBKDF2 is ....... Copy the long password hash in its entirety. # pfedit /rpool/boot/grub/custom.cfg Insert the lines: set superusers="[username]" password_pbkdf2 [username] [password hash] Restart the system.
