An anonymous reader writes "The Obama administration on Tuesday declassified part of the Comprehensive National Cybersecurity Initiative created during the Bush administration, outlining offensive and defensive strategies for protecting information networks. The initiative was originally intended to unify efforts of a number of government agencies into a comprehensive strategy to protect the nation's computer networks. 'One area in which the government did officially disclose new details was Einstein 3, a program to protect civilian government systems from intrusion by deploying sensors on the networks of private telecommunications companies. For the first time, the government disclosed officially that the program would use technology developed by the NSA, the nation's largest intelligence agency. It also said that the Department of Homeland Security, which would run the program, would share malicious code data with the NSA but not the content of communications, such as e-mails.'"
