Evaluating Network Security Based on Attack Graph
Xiang Yang Gao, Xue Qin Xu, Min Wang · Advanced materials research · 2013
By now, Attack Graph (AG) is widely applied to the field of network security assessment. In the AG, each vertex has a value that implies the probability of the exploit and each edge represents the relationship between the exploits. In this paper we design an AG model and propose an approach which integrates the AG model with the Dynamic Bayesian Network (DBN). The approach not only strengthens the rationality of uncertain reasoning, but also provides a quantitative assessment of network security status. We evaluated the approach by experiment. The results showed that our model is rather accurate and the performance of it is competitive.
