摘　　要：本文详细介绍了基于小波变换的异常检测技术的原理和检测模块的实现,通过实验结果说明这是一种检测流量异常的有效手段。而且能识别出正常的突发流量和攻击流量,从而提高了报警的准确性。而且此方法较低的时间复杂度也适合大流量下的数据处理。This paper has introduced anormaly examination technology principle and the examination module realization based on the wavelet variance in details, through the experimental result explained this is a kind of effective method for current anomaly examination. Moreover can distinguish normal arise suddenly the current and the attack current, thus enhanced the accuracy for warnning. At last this method lower time consumption also suits for data processing under great current capacity.
