Rule Text

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

Assessment Procedure

Check Text

Verify RHEL 10 enforces group ownership of the "/boot/grub2/grub.cfg" file with the following command:

$ sudo stat -c "%G %n" /boot/grub2/grub.cfg
root /boot/grub2/grub.cfg

If the "/boot/grub2/grub.cfg" file does not have a group owner of "root", this is a finding.

Implementation Procedure

Fix Text

Configure RHEL 10 to enforce group ownership of the "/boot/grub2/grub.cfg" file.

Change the group owner of the file "/boot/grub2/grub.cfg" to "root" by running the following command:

$ sudo chgrp root /boot/grub2/grub.cfg
