AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE: GEN005750 (in versions v1 r14 through v1 r10)

Title

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

Discussion

Failure to give group ownership of the NFS export configuration file to root or a system group 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

Check the group ownership of the NFS export configuration file. Procedure: # ls -lL /etc/exports If the file is not group-owned by root, bin, sys, or system, this is a finding.

Fix Text

Change the group ownership of the NFS export configuration file to root, bin, sys, or system. Procedure: # chgrp root /etc/exports
