| 摘 要： | 分析DDoS攻击的形成及特征,对各种拒绝服务攻击的实现算法进行对比分析。重点研究可用于检测和防御基于HTTP协议的DDoS攻击的方法,消除或者减少HTTP-Flood攻击对Web服务器的影响,从而达到保护Web服务器的目的。最后,将这种检测防御方法移植到Web应用防火墙（WAF）的DDoS模块中,实现Web服务器防范DDoS攻击的最终解决方案。

| Abstract: | The paper analyzes formation and features of DDoS attacks, compares the algorithms of refusal service attacks. It focus- es on a method used to detect and defense HTFP protocol-based DDoS attack, to eliminate or reduce the impact of HTYP-Flood attack on web server, so as to protect web server. Then this method is applied in DDoS module of web application firewall （WAF） to get the solution on web server defensing DDoS attack. |
