Powner listed a number of criticisms of the DHS cyber efforts, including what GAO sees as a difficulty to develop relationships with other federal agencies, with state and local governments, and with private industry. DHS also has no generally accepted methodologies for analyzing Internet attacks, and it has not fully developed a plan to respond to such attacks on utility control systems, Powner said.
Asked if terrorists had capabilities to cause major Internet disruptions, Powner said organized crime and foreign intelligence groups seem to be involved in cybercrime, but he wasn't sure about current activities of terrorist groups.
"If we have a major disruption in the Internet today, the question is, who is in charge of reconstituting the Internet," Powner added.
"Who is?" Coburn asked.
"Multiple players, I think, is the answer," Powner said.
Purdy seemed to disagree, saying DHS would coordinate the rebuilding of the Internet after a major attack.
