WASHINGTON (AP) — The White House is warning foreign adversaries that the U.S. is preparing to step up its offensive cyber capabilities as part of a new government-wide strategy.

President Donald Trump on Tuesday is signing a National Cyber Strategy that furthers his lifting of Obama-era constraints on offensive actions.

National Security Adviser John Bolton says, "We're going to do a lot of things offensively," adding, "Our adversaries need to know that."

Bolton says the reason for the new strategy is that "Americans and our allies are under attack every day in cyberspace."

The strategy directs federal agencies to work with state and local governments to shore up government systems, and to coordinate with private-sector companies to address threats.

Bolton says the U.S. is aiming "to create the structures of deterrence" in cyberspace.
