Homeland Security Secretary Janet Napolitano is calling for the formation of a special reserve of computer experts to help protect the nation from cyberattack. Napolitano noted that the power infrastructure could be brought down by attacks on control systems from hostile nations or terrorists or from severe storms. "If you think that a critical systems attack that takes down a utility even for a few hours is not serious, just look at what is happening now that Mother Nature has taken out those utilities," she said in reference to Hurricane Sandy and its remnants.
