Defenses against botnet-based Distributed Denial-of-Service (DDoS) attacks must demonstrate that in addition to being technically feasible, they are also economically viable, particularly when compared with the two most widely deployed defenses - simple massive over provisioning of resources to absorb and handle DDoS traffic, and \"Scrubbing\" of incoming traffic by the victim's ISP. The authors argue that the key to cost-effective handling of DDoS attacks on a network such as the Internet is accountability, meaning that the sources of all traffic can be accurately and reliably identified, and receivers can effectively block traffic to them from any source.
