| Description |
|---|
| 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. |
| ℹ️ Check |
|---|
| 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 |
|---|
| 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 |
