摘 要: 为了能快速有效地识别出应用层DoS攻击,提出一种基于HMM的应用层DoS攻击检测方法。该方法以应用层协议关键词和关键词之间的时间间隔作为输入,采用隐马尔可夫模型来快速检测应用层DoS攻击。实验结果表明,该方法对应用层上的多种DoS攻击都具有很高的检测率和较低的误报率。 In order to quickly and effectively identify the application-layer DoS attacks, this paper presented a detection method based on HMM. In this method, the input was the application-layer protocol's keywords and their inter-arrival times. Then, it used the hidden Markov model to detect application-layer DoS attacks. The experimental results show that the proposed method is valid to discover several different application-layer DoS attacks with relatively high detection ratio and low false positive ratio.
