Cybersecurity should be left neither to the free market nor to the military to solve, Department of Homeland Security (DHS) secretary Janet Napolitano said in a speech in Washington, D.C., last week as she reasserted her agency's role as the locus of cybersecurity authority in the federal government.
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."
