Network attack graph was an important tool for network security analysis. With inefficient generating algorithm, previous attack graphs for network assessment and analysis were in large-scale. As building model more reasonably, a simple, flexible and efficient method to generate host-based attack graph was proposed. Based on the generated host-based attack graph, an approach of analyzing network security by using theory of iterative matrix was described. It is proved to be intuitive, efficient and accurate, as it describes the overall security situation of network and facilitates network security administrator to identify the key hosts.
