Surviving Distributed Denial-of-Service Attacks

Business organizations and government agencies that depend on an Internet presence but operate without effective DDoS protection mechanisms put their operations at unacceptable risk. Unfortunately, the varieties of DDoS attacks, the incomplete information we have about them, the difficulty of large-scale testing, and the need for a distributed response at many points make defending against DDoS attacks a challenge. Because no silver bullet exists, businesses and government entities should have comprehensive mechanisms in place if they hope to prevent an attack-or failing that, survive one.
