| 摘要: |
| 随着信息技术安全问题的日益突出，对网络系统进行安全分析日益重要。提出了一种基于图论的网络安全分析方法NEG-NSAM，在进行网络参数抽象和脆弱性关联分析的基础上，构造网络渗透图模型，刻画了威胁主体逐步渗透安全目标的动态过程。针对大规模网络环境，提出了渗透图简化算法。最后，运用NEG-NSAM方法进行了实例分析，验证该方法的可行性和有效性。 |

| Abstract: |
| As information technology security issues become more prominent, the network system security analysis is becoming increasingly important. The paper presents NEG-NSAM, a network security analysis method. Based on network parameters abstract and vulnerability correlation analysis, the network exploitation graph model was constructed, and the dynamic process of a gradual infiltration of the main threats to security objectives was characterized. For large-scale network environment, the simplified algorithm of network exploitation graph model was proposed. Finally, the NEG-NSAM was used to exemplify the network and verify the feasibility and effectiveness of the method. |
