The National Cyber Study Group (NCSG) was the original interagency group that was convened to do brainstorming and information-gathering as preparation for establishment of the Comprehensive National Cybersecurity Initiative (CNCI). In May 2007, the President directed the Director of National Intelligence to conduct a review of the federal government’s cybersecurity status. In response, the Director established the NCSG, composed of senior executives from over twenty agencies, led by ODNI. During the course of its work, the NCSG gathered information about major civilian, defense, and intelligence agencies to understand their roles and responsibilities in federal cybersecurity efforts. The NCSG met twice a week for several months to understand agencies’ roles in national cybersecurity, their capabilities, and the overall threats to federal networks.
