Abstract: Distributed denial of services ( DDoS) is the most important security problem for IT managers. These attacks are very simple organized for intruders and hence so disruptive. Moreover, its serious damage has been increased, the detection and defense of this attack has specific importance among network specialists. A new taxonomy of DDoS attack and defense mechanism has been proposed in this paper. It comprises all types of attacks and provides a comprehensive point of view for DDoS attacks. We introduce a useful tool that can be employed to a sophisticated selection defense method for DDoS attacks. The comprehensive defense classification will help to find the best strategy to overcome the DDoS attack.
