DDoS flood attacks detection based on fuzzy theory
基于模糊理论的分布式拒绝服务攻击检测

To resolve the problem of detecting Distributed Denial of Service(DDoS) attacks, a dynamic threshold detection method based on fuzzy logic was proposed.Through fuzzy compound operation analysis and according to nearest neighbor principle,a decision was got,which is the attack level(trust degree) of detected packet.Web security masters can make responses betimes according to the result,and the responses can save furthest the loss under real time attacks.
