Description
If the system allows a user to boot into single-user or maintenance mode without authentication, any user that invokes single-user or maintenance mode is granted privileged access to all system information.

Who does this work

17 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-261268r1184366_chk)

Note: If the system does not use UEFI, this requirement is not applicable. Verify that SLEM 5 has set an encrypted GRUB bootloader password with the following command: > sudo cat /boot/efi/EFI/BOOT/grub.cfg | grep -i password password_pbkdf2 root grub.pbkdf2.sha512.10000.03255F190F0E2F7B4F0D1C3216012309162F022A7A636771 If the GRUB bootloader password entry does not begin with "password_pbkdf2", this is a finding.

Fix Text (F-64905r1184365_fix)

Note: If the system does not use UEFI, this requirement is not applicable. Configure SLEM 5 to encrypt the GRUB bootloader password. Generate an encrypted GRUB bootloader password for root with the following command: > grub2-mkpasswd-pbkdf2 Enter Password: Reenter Password: PBKDF2 hash of your password is grub.pbkdf2.sha512.10000.03255F190F0E2F7B4F0D1C3216012309162F022A7A636771 Using the hash from the output, modify the "/etc/grub.d/40_custom" file and add the following two lines to add a boot password for the root entry: set superusers="root" password_pbkdf2 root grub.pbkdf2.sha512.03255F190F0E2F7B4F0D1C3216012309162F022A7A636771 Generate an updated "grub.conf" file with the new password using the following commands: > sudo grub2-mkconfig --output=/tmp/grub2.cfg > sudo mv /tmp/grub2.cfg /boot/efi/EFI/BOOT/grub.cfg
