Fix Recommendation

Configure the "/etc/fstab" to use the "nosuid" option on file systems that are being imported via NFS.

Check Contents

Verify that file systems being imported via NFS are mounted with the "nosuid" option with the following command:

$ sudo grep nfs /etc/fstab | grep nosuid

UUID=e06097bb-cfcd-437b-9e4d-a691f5662a7d /store nfs rw,nosuid,nodev,noexec 0 0

If a file system found in "/etc/fstab" refers to NFS and it does not have the "nosuid" option set, this is a finding.
