Check Text ( C-46212r2_chk )
To verify the "nodev" option is configured for all NFS mounts, run the following command: $ mount | grep "nfs " All NFS mounts should show the "nodev" setting in parentheses, along with other mount options. If the setting does not show, this is a finding.

Fix Text (F-43601r1_fix)
Add the "nodev" option to the fourth column of "/etc/fstab" for the line which controls mounting of any NFS mounts.
