Check: GEN005840

AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE: GEN005840 (in versions v1 r14 through v1 r10)

Title

The NFS server must be configured to restrict file system access to local hosts. (Cat II impact)

Discussion

The NFS access option limits user access to the specified level. This assists in protecting exported file systems. If access is not restricted, unauthorized hosts may be able to access the system's NFS exports.

Check Content

Check the permissions on exported NFS file systems. Procedure: # exportfs -v If the exported file systems do not contain the rw or ro options specifying a list of hosts or networks, this is a finding.

Fix Text

Edit /etc/exports and add ro and/or rw options (as appropriate) specifying a list of hosts or networks which are permitted access. Re-export the file systems.
