Napolitano Calls Cyber Security A Shared Responsibility

The Department of Homeland Security is ramping up its involvement with the private sector to secure cyberspace, an effort that is a "shared responsibility" of the federal government and technology companies alike, DHS Secretary Janet Napolitano said.

Likening cyberspace to a neighborhood, marketplace, or schoolyard, Napolitano said that the federal government sees it as a "civilian space." This idea informs how the DHS works to protect cyberspace by trying to keep critical infrastructure and its connections to that civilian space safe.Sec Napolitano said the DHS is currently building a "technical ecosystem" based on its concept of cyberspace as a "distributed, civilian space," and also is creating a policy ecosystem to support that.
