Does the world need a peace treaty for cyberspace?

Hamadoun Toure, the Secretary General of the UN’s International Telecommunications Union, thinks so.

He’s circulating a proposal that would require countries to prevent their infrastructure from being used in a cyber attack. And signatories would have to pledge not to start a cyber-war themselves.

But what would a full-fledged conflict online look like? To find out, we talk with Roger Cressey, a senior counter-terrorism official at the National Security Council under the Clinton and Bush administrations. And we hear from Stewart Baker, assistant director at the Department of Homeland Security Department under Bush.

But many others believe the best way to think about online security isn’t really in terms of war and peace. We might be reading the wrong Russian author. How about crime and punishment?
