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.
Remediation:
Run the following command to set the root user default group to GID 0:
# usermod -g 0 root
Parameter:
[0]
Technical Mechanism:
Run the following command to set the root user default group to GID 0:
# usermod -g 0 root
