The Perfect Citizen project is purely a research-and-engineering effort, not an attempt to monitor companies against cyberattack, the National Security Agency said Thursday.

The NSA issued a brief explanation of the new project in response to a Wall Street Journal story that described Perfect Citizen as a government system designed to monitor vital agencies and private utilities against potential cyberthreats. The project would establish a series of sensors installed throughout various computer networks that would raise an alarm in case of a pending cyberattack, according to the Journal.

But in an e-mail statement attributed to NSA spokeswoman Judith Emmel, the … Read more
