Associated Press | A top Pentagon official says a government computer security system that can thwart cyber attacks should be extended to private businesses.

Deputy Defense Secretary William J. Lynn III says discussions are in the very early stages to allow the government to extend technology from the Einstein 2 and Einstein 3 computer defense programs to private firms.

The idea raises a myriad of legal, policy and privacy questions, including how it would work and what information would be shared between the government and businesses.
