Title

The NFS export configuration file must be group-owned by root, bin, or sys. (Cat II impact)

Discussion

Failure to give group ownership of the NFS export configuration file to root or system groups provides the designated group owner and possible unauthorized users with the potential to change system configuration which could weaken the system's security posture.

Check Content
