Pentagon Will Help Homeland Security Department Fight Domestic Cyberattacks

The Obama Administration has adopted new procedures for using the Defense Department's vast array of cyberwarfare capabilities in case of an attack on vital computer networks inside the United States, delicately navigating historic rules that restrict military action on American soil.

The system would mirror that used when the military is called on in natural disasters like hurricanes or wildfires. A presidential order dispatches the military forces, working under the control of the Federal Emergency Management Agency. Under the new rules, the president would approve the use of the military's expertise in computer-network warfare, and the Department of Homeland Security would direct the work. Officials involved in drafting the rules said the goal was to ensure a rapid response to a cyberthreat while balancing concerns that civil liberties might be at risk should the military take over such domestic operations. The rules were deemed essential because most of the government's computer-network capabilities reside within the Pentagon -- while most of the important targets are on domestic soil, whether within the government or in critical private operations like financial networks or a regional power grid.
