An Attack Path Generation Methods Based on Graph Database

With the popularity of network technology and the expansion of network scale, the network security risks are increasingly serious. Network vulnerability assessment methods, a technology of active network security defense, have attracted many researchers. Most existing network vulnerability assessment methods store different types of data in different ways, which makes querying and analyzing inefficient, especially in the complex large-scale network environment. In order to solve this problem, this paper proposes a method of network vulnerability assessment based on graph database. The network host information, association relationship between hosts and vulnerability information of the target network are stored in the graph database, the query and analysis are carried out by using the graph database query language. Graph database stores the information of the network hosts, association relationship among hosts and vulnerabilities of the target network. The graph database query language supports querying and analysis. Visualizing the network topology, vulnerability information and all possible attack paths provides a reference to develop the network security protection strategy. Experiments' results illustrate that the method runs efficiently and helps with querying and analysis, which is applicable to large-scale complex network environment.
