This paper presents a comprehensive survey on filtering-based defense mechanisms against distributed denial of service (DDoS) attacks. Several filtering techniques are analyzed and their advantages and disadvantages are presented. In order to help network security analysts choose the most appropriate mechanism according to their security requirements, a comparative classification of these methods is provided. The relevant research efforts are identified and discussed for rendering the current state of the art in the literature. This classification will also serve researchers to address weaknesses of these filtering methods, and thus mitigate DDoS attacks using more effective defense mechanisms.
