The US Navy will soon operate as a cyber warfighting platform, ready to attack rogue nations when ordered by the White House. A top military commander tipped the initiative at a defense conference, saying "you don't win a knife fight without swinging a knife." US intelligence services already launch limited cyber strikes, as they did against North Korea following the Sony hacking incident. But assigning such attacks to a military arm is a signal that the US wants a stronger deterrent against hacking aggression from China, Russia and other nations. There's no word on whether the Navy's new role is part of the new US Cyber Threat Intelligence Integration Center initiative.
