Data on possible threats- ranging from viruses, to hoaxes, to random threats, to news events, and computer intrusions- must be continually collected and analyzed from a wide spectrum of globally distributed sources. Once an imminent threat is identified, appropriate warnings and response actions must be effectively coordinated among government agencies, the private sector, and other nations. It is important that this function be carried out as effectively, efficiently, and quickly as possible in order to ensure continuity of operations as well as minimize disruptions.
