Check Text (C-215330r991589_chk)

Check the permissions on exported NFS file systems by running command: # exportfs -v /export/shared -ro,access=10.17.76.74 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 (F-16526r294442_fix)

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: # /usr/sbin/exportfs -a
