Pentagon's new cyber strategy cites US ability to retaliate

PROTECTING HOME AND HEARTH: Carter said the primary focus of the cyber strategy was defence.

REDWOOD CITY, California: US Defence Secretary Ash Carter is due to unveil an updated cyber strategy that will stress the military's ability to retaliate with cyber weapons, a capability he hopes will help deter attacks. 

The strategy presents a potentially far more muscular role for the US military's cyber warriors than the Pentagon was willing to acknowledge in its last strategy rollout in 2011 and singles out threats from Russia, China, Iran and North Korea.
