Distributed denial of service (DDoS) attacks can cripple an organization, a network, or even an entire country, and they show no sign of slowing down. DDoS attacks may only make up a small percentage of security threats, but their consequences can be devastating. According to Imperva Research Labs, DDoS attacks tend to come in waves.
