======5.4.3 Ensure default group for the root account is GID 0 (Scored)======
=====Profile Applicability=====
Level 1 - Server
Level 1 - Workstation
=====Description=====
The usermod command can be used to specify which group the root user belongs to. This affects permissions of files that are created by the root user.
=====Rationale=====
Using GID 0 for the ''root'' account helps prevent root-owned files from accidentally becoming accessible to non-privileged users.
=====Audit=====
Run the following command and verify the result is 0:
# grep "^root:" /etc/passwd | cut -f4 -d:
0
=====Remediation=====
Run the following command to set the ''root'' user default group to GID 0:
# usermod -g 0 root
