The Cyber Incident Data Detection and Analysis Center (CIDDAC) is a non-profit organization that integrates private, public and government cooperation to facilitate the real-time sharing of cyber attack data. It is the first real-time cyber threat sharing system implemented to protect the nation's critical infrastructure. It fundamentally changed the way the U.S. responds to criminal and terrorist use of the Internet by providing voluntary automated incident reporting to law enforcement when security breaches occur, while protecting the identity and privacy of its members and their data.
