Pentagon looks for weapons to wage cyber warfare

The US government needed "more and better options" to safeguard the country from assaults on sensitive computer networks and had to invest in both offensive and defensive tools, said Regina Dugan, director of the Pentagon's research arm, the Defence Advanced Research Projects Agency (DARPA) yesterday.

"Malicious cyber attacks are not merely an existential threat to our bits and bytes. They are a real threat to our physical systems, including our military systems," Dugan told a conference.

"To this end, in the coming years we will focus an increasing portion of our cyber research on the investigation of offensive capabilities to address military-specific needs," she said.
DARPA has proposed boosting funding in cyber research in the proposed 2012 budget from USD 120 million to USD 208 million and the Defence Department leadership has called for USD 500 million in funding for cyber security over the next five years, she said.

With other countries pursuing cyber warfare capabilities and the danger from digital attacks growing by the day, the United States had to look at developing "offensive" arms to protect national security, said Dugan, without specifying what weapons could be employed.

"Our first goal must be to prevent war. We do so in part by being prepared for it. Failing prevention, however, we must accept our responsibility to be prepared to respond," she said.

Even while preparing for possible digital war, US policy makers must protect civil liberties and the "peaceful shared use of cyberspace," she added.

A recent DARPA analysis of cyber security over several months concluded that the US government had to rethink how it defends cyberspace to keep up with a threat evolving at lightning speed.

"Why is it that despite billions of dollars in investment and the concerted efforts of many dedicated individuals, it feels like we are losing ground?"

The DARPA study found that security software had grown more and more complex over the past two decades -- involving up to ten million lines of code -- while various viruses and other digital assaults required an average of 125 lines of code for malware, according to Dugan.
