- Facing hackers’ intelligent attacks and multi-source information from various security equipments, evaluating real-time risk of the network becomes more and more complicated to handle. This paper proposes a new attack graphs model(NAG)-based analysis method in order to assess the impact on the network system made by multiple vulnerabilities. Aiming at simplify the attack graphs, we combined attack graphs with Bayesian theory and put forward an optimized algorithm to remove the cycles in attack graphs. By importing Common Vulnerability Scoring System (CVSS) and attack evidence, the assessment method in this paper can dynamically evaluate the partial or entire network security. Experimental results show that the method can reflect the changing situation of the network security.
