Security threats and crises faced by governments are different from what they were in the past. The mission and role of information in safeguarding national security and welfare are more important in an era of globalization. How governments utilize efficient intelligence mechanisms in peacetime and during crisis management, and grasp early warning intelligence and timely, correct information to promote policies of national interest and to resolve threats are essential to governance capacity. This paper aims to use intelligence theory for crisis management, and the principle of producer-consumer. It then analyzes the function of intelligence in national security, the relationship between intelligence and policy, and the interactive relationship between intelligence and policy makers. In addition, the cases of the 9/11 and the Boston Marathon bombings are discussed. Our national security intelligence system should enhance the function of intelligence integration and crisis management to handle traditional security and non-traditional security threats.
