At the recent Black Hat Federal IT security conference in Arlington, 
Va., former White House cybersecurity adviser Paul Kurtz called for a 
public discussion of what he called taboo subjects. If we are to have a 
comprehensive cybersecurity strategy, he said, we must begin thinking 
about how to effectively integrate the intelligence community and 
military services into the program.

A new war, somewhat akin to the Cold War, is simmering online, but the 
nation has yet to develop a strategic plan for using military and 
intelligence resources in defending its information infrastructure. This 
is not to say that the intelligence community is not gathering large 
amounts of information or that the Defense Department is not developing 
the capacity to defend itself, and retaliate, online. But intelligence 
data has not been integrated into the overall picture of what is going 
on online, and there are no protocols for determining what constitutes 
an act of cyber warfare and what the appropriate response would be, 
Kurtz said.

"We need to have a public discussion," he said, on sharing intelligence 
with law enforcement and the private sector and on the use of military 
weapons in cyberspace.

At the same conference, some companies demonstrated tools that enable 
secure information sharing, using cryptographic techniques that allow 
data mining across multiple databases without compromising privacy. 
Andrew Lindell, chief cryptographer at Aladdin Knowledge Systems, showed 
how to ensure privacy on both sides of the search so that data is not 
unnecessarily exposed to the searcher and the searcher does not have to 
reveal what he is looking for.

"It's a trivial solution," possible with commercial technology, Lindell 
said.
