| 摘 要： | 针对传统方法难以实时有效地检测分布式拒绝服务攻击(DDoS)的问题,通过DDoS攻击的基本特征分析,从理论上严格区分了DDoS攻击流和正常突发流,并且在此基础上提出了一种基于特征参数相关性的DDoS攻击检测算法.该算法能在早期检测出DDoS攻击流,而这时的DDoS攻击包特征并不明显,并且该算法能有效地区分DDoS攻击流和正常的突发流.实验结果表明了该算法的有效性和精确性.

| Abstract: | As traditional methods can not effectively detect DDoS attacks in time,DDoS attacking traffic is distinguished from normal flash crowd traffic on theory by analyzing the basic features of a DDoS and a DDoS attack detecting algorithm based on that is proposed according to the analysis of the essential characteristic of DDOS.The scheme detect a DDoS attack traffic in its early stages when the attacking packet's attribute value has no distinct features.It can differentiate DDoS from normal burst traffic.The simulation shows the algorithm's validity and accuracy. |
