Title: Novel method of evaluating network security based on attack graphs
Abstract: In order to improve networks' total security,this paper presented a novel method of assessing network security based on attack graphs.Firstly,it proposed a definition of vulnerability dependence graph based on attack graphs.Secondly,it divided the factors which impact network vulnerability assessment into three parts: the vulnerability character by itself,the network environment and the relationship between vulnerabilities.Finally,according to the size of network topology,using the evaluation policy from bottom to top and from local to global,it gave the vulnerability assessment intuitively in three levels: the vulnerability,the host and the network.Through a large number of repeated laboratory tests,the experimental results show that this method can assess network security efficiently,help network security managers guard the network,which improves networks viability,and improves the ability of responding to sudden attacks.So it has great theoretical value,economic value and social significance.
