The US military announced a new "cyber command" designed to wage digital warfare and to bolster defenses against mounting threats to its computer networks. The move reflects a shift in military strategy with "cyber dominance" now part of US war doctrine and comes amid growing alarm over the perceived threat posed by digital espionage coming from China, Russia and elsewhere.
President Barack Obama has put a top priority on cyber security and announced plans for a national cyber defense coordinator. A recent White House policy review said that "cybersecurity risks pose some of the most serious economic and national security challenges of the 21st century." Obama has promised privacy rights would be carefully safeguarded even as the government moves to step up efforts to protect sensitive civilian and military networks.
