"Cyberspace is fundamentally a civilian space," Napolitano said. "There are some who say cybersecurity should be left to the market, and there are some who characterize the Internet as a battlefield. Both the market and the battlefield analogies are the wrong ones to use. We should be talking about this as, fundamentally, a civilian space and a civilian benefit that employs partnerships with the private sector and across the globe."
The DHS has taken the lead in the federal government on cybersecurity measures via its National Cyber Security Division. That group this year headed up a major international and inter-governmental cyber exercise, Cyber Storm III, and continued ramping up efforts to protect federal systems and critical infrastructure like power plants.
Napolitano has been an ardent supporter of DHS' leadership role, but while she implied a DHS-centered view of cybersecurity, she did admit that DHS can't do it alone. "It is our goal to build one of the very best teams that we can to tackle the cybersecurity challenge," she added. "No single industry or agency, quite frankly, can manage it. Cybersecurity is about effective partnerships and shared security."
This year, DHS has expanded partnerships with private industry, for example doing a substantial amount of investigative work on the Stuxnet worm that infiltrated power plant control systems earlier this year and working to build up liaisons with private sector industries it deems to be "critical."
DHS has also improved its partnerships with military and military intelligence this year. In October, DHS and the Department of Defense signed a cybersecurity pact to improve collaboration between the agencies and boost DHS' encryption and decryption capabilities by comingling National Security Agency (NSA) cryptologic analysts and DHS cybersecurity leadership in a move that signaled progress in a sometimes uneasy relationship with the military.
"We're working very closely along and across the federal family, particularly having worked out really the thorny issues involving how the NSA is to be used in a civilian context for protection and prevention, as well as in a military context," Napolitano said last week.
