Check: GEN005800

AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE: GEN005800 (in versions v1 r14 through v1 r10)

Title

All NFS-exported system files and system directories must be owned by root. (Cat II impact)

Discussion

Failure to give ownership of sensitive files or directories to root provides the designated owner and possible unauthorized users with the potential to access sensitive information or change system configuration which could weaken the system's security posture.

Check Content

Check for NFS exported file systems. Procedure: # exportfs -v This will display all of the exported file systems. For each file system displayed, check the ownership. Procedure: # ls -lLa <exported file system path> If the files and directories are not owned by root, this is a finding.

Fix Text

Change the ownership of exported file systems not owned by root. Procedure: # chown root <path>
