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
