Cybersecurity chief: Congress must act to improve defenses against destructive cyberatttack

The head of the Pentagon’s Cyber Command on Monday called for swift action in Congress to sort out roles, standards and authorities for government agencies charged with defending against destructive computer attacks.

Army Gen. Keith Alexander, speaking at the American Enterprise Institute think tank, said the time for legislative action is now, before the nation is hit with a major cyberattack — an event he called increasingly likely.
