Fix Recommendation

Edit /etc/vfstab and add the nosuid option for all NFS file systems. Remount the NFS file systems to make the change take effect.

Check Contents

Check the system for NFS mounts not using the nosuid option.

Procedure:
# mount -v | grep " type nfs " | grep -v nosetuid
OR
# grep nfs /etc/mnttab | grep -v nosuid | grep -v :vold

If the mounted file systems do not have the nosetuid/nosuid option, this is a finding. NOTE: Mount options for the volume management daemon (vold) are controlled by the /etc/rmmount.conf file.
