Title

All NFS exported system files and system directories must be group-owned by root, bin, or sys. (Cat II impact)

Discussion

Failure to give group ownership of sensitive files or directories to root provides the members of the owning group with the potential to access sensitive information or change system configuration which could weaken the system's security posture.

Check Content

List the exports. # cat /etc/dfs/dfstab OR # more /etc/dfs/sharetab For each export, check the ownership information. # ls -ldL <export> If the directory is not group-owned by root, sys, or bin this is a finding.

Fix Text

Change the group owner of the export directory. # chgrp root <export>
