摘　　要：随着经济全球化深入发展,科技革命不断取得突破,其中以信息网络技术为最,信息网络化的进程也不断将人类推向新的历史高度.但与此同时网络入侵率也随之增加,成为了网络技术的一大弊端.为了降低攻击者对网络的入侵和减少攻击手段,在原算法的基础上采用CUSUM算法来检测网络入侵,并优化其期望值和警告阈值.经检测发现,改善后的算法比原算法更具检测精度.With the in-depth development of economic globalization,the revolution of science and technology constantly breakthroughs,with the greatest information network technology,the progress of the information network will also constantly human beings into a new historical height.But at the same time the network invasion rate also increased,become the one big drawback of network technology.In order to reduce the invasion of the attacker to network and reduce the attack means,and on the basis of the original algorithm using CUSUM algorithm to detect network intrusion,and optimize their expectations and warning threshold（s）.After testing found that the improved algorithm are more accuracy than the original algorithm.
