The one problem with an encapsulated file share (either NFS or samba) is that it sets 
up a permanent link between your server segment and your internal network. Granted it 
is encrypted, but any breach of your server provides a sub directory where trojans can 
be left to become visible on your internal network.

The advantage of the SCP solution over this is that there is no long term connection. 
Each transfer  is for the wanted data and that data only. This lessens the risk of 
cracker monitoring traffic on the share and the channel between internal and server 
segment is not available unless you are actually transferring data (although such 
connections could be built from SSH/NFS with some scripts). SCP and NFS tunneling 
under SSH use the same basic encryption methodology so there is no difference in 
cryptographic strength.

This is probably what we'll end up doing.

However, after my post I cam across an article on using ssh and TCP NFS to
implement a "secure NFS", here's a link to the article,
http://www.samag.com/documents/s=4072/sam0203d/sam0203d.htm. I was
wondering if anyone had looked at or implemented this, and what their
opinion of it was.

Thanks,
Josh
