The C-STARR program was conducted with the intent to support establishment of a sustained regional initiative that would enable the development and maintenance of critical cyber capabilities and reduce the vulnerabilities of local government and the private sector to cyber attack. The program included participation from the public and private sector, recognizing that a number of regional cyber vulnerabilities and corresponding prevention, preparedness, response, and recovery capabilities are maintained across jurisdictional and administrative boundaries. This program was intended to leverage and expand upon the best practices and lessons learned through previous successful cyber security programs conducted in Southern California and attempted to address the evolving threats to cyber security by integrating timely and relevant subject matter to support its content. Over 100 personnel from 78 organizations participated in the C-STARR program, which included federal and local government agencies, as well as the private sector.
