A distributed denial of service (DDoS) attack is a multitude of compromised systems attacked by a single target. A flood of incoming messages sent to the target system forces it to shut down causing services to be denied to the legal user.
Two type of DDoS attacks, a network-centric attack which overloads a service by using up bandwidth and an application-layer attack which overloads a service or database with application calls.
Perpetrators of the DDoS attacks usually target sites or services hosted on web servers such as banks, credit card payment gateways, and even root name servers.
DDoS attacks have been used as a form of resistance. Richard Stallman has stated that DDoS is a form of Internet Street Protest.
