There's a happy medium in there somewhere; it's not clear that having (to use the examples given) air traffic control computers directly on the Internet has sufficient value to outweigh the risks. However, it seems that being able to securely gateway appropriate information between the two networks should be manageable, certainly a lot more manageable than the NxM complexity involved if you try to do it by securing each and every Internet-connected ATC PC individually.
What makes you think that isn't exactly what this "Cyber Shield" project is supposed to do? Heck, what makes you think that's not the way most of these systems already work today? Do people really think the guy in the airport control tower is really surfing Facebook while he's controlling aircraft on the same computer, or that capability is even what is under consideration? -- Brandon Ross AIM: BrandonNRoss ICQ: 2269442 Skype: brandonross Yahoo: BrandonNRoss
