Distributed denial of service (DDoS) attacks aim to disrupt the service of information systems by overwhelming the processing capacity of systems or by flooding the network bandwidth of the targeted business.
Recently, these attacks have been used to deny service to commercial web sites that rely on a constant Internet presence for their business. The attacks differ from traditional DDoS attacks in the targeted nature and shear number of attacking hosts.
