DDoS攻击分类与效能评估方法研究

DDoS攻击是一类常见而又难以防范的网络攻击模式，对Internet网络系统的正常运行构成了巨大威胁。DDoS攻击的分类方法和攻击效能评估是计算机网络攻防对抗研究的一项重要而紧迫的任务。本文介绍了DDoS攻击的原理、方法、一般概念和主要目标，研究了基于攻击代理的传播模式、通讯方式、作用机制等特征的DDoS攻击分类方法体系，分析了DDoS攻击的攻击效能评价指标体系。在分析了DDoS攻击效能评估的特点的基础上提出了DDoS攻击效能评估的模糊评价评估模型。

Study on Taxonomy and Effectiveness Evaluation of DDoS Attacks

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.
