A '''distributed denial of service attack (DDoS)''' occurs when multiple systems distributed around the Internet send a large volume of bogus requests to a targeted system or systems, usually one or more web servers. When a server is overloaded with connections or if its bandwidth is saturated, new connections can no longer be accepted or old ones maintained, thereby denying service to the website's legitimate visitors. It's like having a discussion in a small group, when a large mob surrounds you and they all begin shouting loudly. The real communication ceases as it is lost in the noise. | A '''distributed denial of service attack (DDoS)''' occurs when multiple systems distributed around the Internet send a large volume of bogus requests to a targeted system or systems, usually one or more web servers.
