I'm preparing ahead-of-time for the avalanche (inevitable from what I read) of BYOD requests as shadow IT starts appearing around the place (e.g Tablets that just 'turn up') and users want to be able to access data via smart phones in the field etc
I'm looking towards the 'enclose the keep' model - ie protect the servers and their data and services and let the LAN and the devices on it fend for themselves (within reason)
Anyway, WEBDAV seems to offer a pretty good way for any device to access data shares from anywhere using the same URL as you can put it over SSL to protect the credentials and encrypt the stream, plus it still uses NTFS permissions at the back end to limit what a user can see or do.
As a standard windows user, you can map a URL as a network drive (or have it mapped for you) so it looks like a standard SMB share.
So what are the downsides and yawning security holes I'm not aware of (e.g. transfer speeds of http vs smb, limits to connections, overheads in processing, anything else?)
