Military links between systems usually traverse the network over Internet (albeit in an encrypted manner, such as with a VPN). Energy firms link sites together via site to site VPNs on the Internet. I wouldn't be surprised if remote support for SCADA networks weren't linked in a similar manner, which would at least make for an interesting fluff article on zdnet. It's a bit like Madagascar in Pandemic 2. What are they going to do? Shut it all (or rather sections of it) down? Then what?
