DDoS detection and defense: client termination approach

A Denial-of-Service attack (DoS) or Distributed Denial-of-Service (DDoS) is an attempt by an attacker to make a computer or network resource unavailable to its legitimate users. In general it is specified by an event in which legitimate user(s) is/are deprived from accessing certain services. Services may be web, mail or any other service which rely on network connectivity. In this paper the DoS or DDoS via incomplete HTTP request, its detection and defense techniques have been discussed with a new approach of detecting and preventing HTTP DoS, Client Termination approach. The approach is based on the fact that the idea of performing HTTP DoS or DDoS needs relatively less number of attackers than other conventional methods of DoS or DDoS, which is still very effective.
