基于动态规划的序列情节告警挖掘

摘要

序列模式挖掘在网络安全领域有非常广泛的应用,特别是对告警数据进行序列情节挖掘,能有效发现未知的异常攻击序列.论文提出了一种基于动态规划的频繁序列求解方法.实验表明,该方法能有效挖掘出告警序列中的频繁情节,并且提高了算法的效率.%Sequential pattern mining is widely used in network security fields,especially applying mining skills to alarm da?ta,with which unknown attacking sequences can be found. This paper proposes a method based on dynamic programming to mine se?quential pattern. The experiments show that this new method can mine the frequent episodes effectively,and it's more efficient.
