Check: GEN005810

SUSE Linux Enterprise Server v11 for System z STIG: GEN005810 (in versions v1 r12 through v1 r9)

Title

All Network File System (NFS) exported system files and system directories must be group-owned by root, bin, sys, or system. (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/exports For each file system displayed, check the ownership. # ls -ldL <exported file system path> If the directory is not group-owned by root, bin, sys, or system, this is a finding.

Fix Text

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