The US strategy of "deterrence" for cyber-attacks could involve a wide range or responses, potentially including the use of conventional weapons, the nation's top cyber-warrior said Monday. Admiral Michael Rogers, who heads the US Cyber Command as well as the National Security Agency, told a Washington forum that the idea of cyber-deterrence is evolving but that there are many ways to get that message across. "Because an opponent comes at us in the cyber domain doesn't mean we have to respond in the cyber domain," Rogers told a cybersecurity forum at George Washington University.
"We think it's important that potential adversaries out there know that this is part of our strategy." He said the US administration demonstrated this recently by ordering economic sanctions against North Korea following a damaging cyber-attack against Sony Pictures.
