Title

RHEL 10 must enforce "root" ownership of the "/boot/grub2/grub.cfg" file.

Control

Verify RHEL 10 enforces ownership of the "/boot/grub2/grub.cfg" file with the following command: $ sudo stat -c "%U %n" /boot/grub2/grub.cfg root /boot/grub2/grub.cfg If the "/boot/grub2/grub.cfg" file does not have an owner of "root", this is a finding.

Discussion

The " /boot/grub2/grub.cfg" file stores sensitive system configuration. Protection of this file is critical for system security.
