If the NFS server is read-only, in support of unrestricted access to organizational content, this is not applicable. The related "root_squash" option provides protection against remote administrator-level access to NFS server content. Its use is not a finding. To verify the "all_squash" option has been disabled, run the following command: # grep all_squash /etc/exports If there is output, this is a finding. |

Remove any instances of the "all_squash" option from the file "/etc/exports". Restart the NFS daemon for the changes to take effect. # service nfs restart |
