Abstract: This paper studies computer network security vulnerability assessment in network security field, and presents an approach for network vulnerability evaluation based on attack graph and security metric. The vulnerability analysis is made with comprehensive simulation of malefactor’s actions and construction of attack graphs. A series of security metrics are computed, with risk assessment techniques to realize the qualitative and quantitative evaluation of network vulnerability.

Key words: vulnerability evaluation, attack graph, security metric, risk assessment
