When security company RSA found itself the victim of a cyber attack recently, the Department of Homeland Security (DHS) was there working alongside the company and other law-enforcement agencies to mitigate the threat and ensure that other systems would not be threatened in the same way.
“We took our understanding of the tools, tradecraft, and techniques used by these malicious actors, and converted it into actionable information that … critical infrastructure sectors could use to employ mitigation measures that would lower their risk to the type of attack we saw at RSA,” DHS Secretary Janet Napolitano said this week.
The move shows the department 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, she said Monday, speaking at the University of California Berkeley College of Engineering. The text of her speech is posted online.
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.
“This is not something we can do by ourselves,” she said. “It requires a full range of partners–including other government agencies, the private sector, as well as individual users of the Internet.”
To that end, 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.
