Michael Chertoff spoke recently at a security conference in the United Kingdom and said that the uncertainty behind cyber war protocol is a weakness that could possibly be exploited by enemies.
"It's the least understood threat and the one where our doctrine is least developed," the BBC quotes Mr Chertoff as saying.
"The greatest stress you can have on security is when there is uncertainty," he later added. "We are now in a state of uncertainty."
Chertoff is right in saying we need to establish a set of rules for how we respond to cyber security, especially as reports of cyber attacks become more common. Chertoff believes a big issue is that people committing these kinds of crimes are unaware of the consequences they face if they are caught. In light of Stuxnet, and other more sophisticated types of cyber warfare, it might be nice to know what the government plans on doing if the U.S. comes under attack.
"It's a real problem and it's growing," Chertoff said. "If we do not address it then we are going to be confronted by an event that's so catastrophic that it cannot be shrugged off."
