摘要
在对网络会话进行时序分析的基础上,提出基于数据流分簇处理的心跳包序列检测方法。对数据流进行时序分簇处理,按周期性特征扩充簇集合,筛除不符合特征的簇对象,根据稳定的簇集合检测心跳包序列。实验结果表明,该方法检测率较高、误检率较低,能够实现实时检测和处理。
Based on timing analysis of network sessions, this paper puts forward a detection approach of heartbeat packet sequence based on clustering processing. It processes the network data stream with time clustering, expands the cluster collection by periodic features, and screens out the clusters which do not meet the characteristics, and detects the heartbeat packet sequence within steady cluster collection. Experimental results show that this approach can achieve higher correct detection rate, real-time detection and processing.
