%X To protect critical information resources in networked environment and evaluate the overall security of network, this paper paper proposed a approach to network security assessment based on probabilities of attack graph nodes. By improving individual probability's computational model of atomic attack and introducing cumulative reachable probability of nodes in the attack graph, it proposed the assessment model of network security risk. Experimental results show that the proposed approach can accurately assess the security level of target states and overall security risk of network.
