DDoS攻击分类与效能评估方法研究

DDoS attack is a common but difficultly defensive computer network attack mode. It threatens the normal operation of the Internet greatly. Study on taxonomy and effectiveness evaluation of DDoS attack is an important and urgent task in the field of computer network attack and defense. In this paper, principle, method, common concept and main object of DDoS attacks are introduced, a taxonomy method of DDoS attacks based on spread mode, communication method and effect mechanism of attack agents is studied, and indexes of DDoS attack effectiveness evaluation are analyzed. The specialties of DDoS attack effectiveness evaluation are also analyzed. Then a fuzzy evaluation model of DEloS attack effectiveness is brought forward.
