Defense Secretary Cites 'New Threat of Warfare' Online

Cyberspace is the battlefield of the future, with attackers already going after banks and other financial institutions and developing the ability to strike U.S. power grids and government systems, Defense Secretary Leon Panetta said. "We confront a whole new threat of warfare in (cyberspace). ... This is an area we've got to pay close attention to. This is the battlefront of the future," he told a business group in Norfolk, Virginia, a city at the center of one of the largest concentrations of military power in the United States.
