摘要:

基于蠕虫病毒传播时其前后被感染节点在传播路径上存在着隐含的因果关系, 提出一种使用贝叶斯网络关联方法在线推测网络蠕虫传播路径的算法, 并通过模拟实验进行验证. 实验结果表明, 该算法较不采用关联的算法提高10%正确率, 更适合在线工作方式.

Abstract:

Though worm is randomly spread, there exists implicit causality between adjacent infected nodes. Based on the analysis of causality, we presented an improved online tracing algorithmBayesian network correlation algorithm to acquire worm propagation path, and analyzed and verified its accuracy and performance through simulation experiments. Experiment result indicates that the detection accuracy of Bayesian network correlation algorithm has been increased by a factor of 10% compared to that of our previous work, this improved algorithm is more suitable for online detection.

Key words: worm, propagation path, correlation, Bayesian network
