一种基于攻击图模型的网络安全评估方法

随着网络的深入和快速发展,网络安全问题日益严峻,研究网络安全的评估方法,具有重要的现实意义。安全漏洞的大量存在是安全问题的总体形势趋于严峻的重要原因之一。详细介绍了攻击图建模方法,给出了攻击图自动生成算法,提出了一种利用数学模型分析攻击图,并对网络系统进行安全评估的方法,最后通过一个虚拟网络环境对网络安全评估方法进行了验证。该方法对攻击图的研究具有现实意义。

An Approach based on Attack Graph for Security Assessment 0f Network

A large amount of security loophole is one of the important causes leading to the severe general security situation. The study on network security assessment is thus of significant practical importance. This paper describes in detail the method for building up the attack graph model, and gives an auto-generating algorithm of attack graph. An approach by using mathematic model to analyze attack graph for security assessment of network is proposed. With a virtual network environment, the method is verified. T...
