The federal government is launching an expansive program dubbed "Perfect Citizen" to detect cyber assaults on private companies and government agencies running such critical infrastructure as the electricity grid and nuclear-power plants, according to people familiar with the program.

The surveillance by the National Security Agency, the government's chief eavesdropping agency, would rely on a set of sensors deployed in computer networks for critical infrastructure that would be triggered by unusual activity suggesting an impending cyber attack, though it wouldn't persistently monitor the whole system, these people said.

Some industry and government officials familiar with the program see Perfect Citizen as an intrusion by the NSA into domestic affairs, while others say it is an important program to combat an emerging security threat that only the NSA is equipped to provide.
