The U.S. desires to believe functioning with additional important country to build up rules of engagement in cyberspace, former director of the CIA Michael Hayden told at the Black Hat discussion. As the state by means of the major stake on the web, the U.S. has been fairly unwilling to engage in such dialogue because of fear that any international negotiations will oblige it to disclose or limit its cyber potential, Hayden said.

Though, the difficulty concerned in defining cyber variance, and in developing an effectual prevention and reaction strategy, are motivating the need for at least some high-level engagement with other country, he said. "We have been actually behind to any worldwide argue on arms constraint in cyberspace," Hayden said. "Our influence in this is going to get weaker as days go by."
