Dependst on your threat model. You could tunnel unencrypted NFS over some
VPN tunnel (open VPN, e.g.). You could do a network-block-device export,
whoch should be encryptable in the standard way. You could export NFS with
a file in it and have that file contain an encrypted LUKS container that
gets loop-mounted on the target. I am sure other options exist.
So ask yourself:
- What does the attacker have access to?
- What can the attacker do at the access point? (With regard to his
capabilities.)
- Does this need to be exported to one or several targets?
- Does the exporting host need access to the exported data?
