It's most non-classified networks that allow http, https or dns access.
You can tunnel effectively through any of them. You could even tunnel
through SMTP if you were ballsy enough. Everyone's been doing this since
1992AD, and I assume that if anyone puts an anomaly detection
application firewall in place on HTTP and HTTPS, there'll be some public
research into covert channels. Maybe Joanna will release something to
explain how egress filtering without an air gap is just amusing.

I guess the whole point is that nothing you can deploy right now
actually protects you from targeted attacks. They just handle worms.
Worms are essentially a bandwidth problem. :>
