根据最大关键度优先的原则选择需要删除的安全要素。实例分析表明

应用该方法制定的增强策略能够提高网络的整体安全性

与传统方法相比

其可操作性更强。

Abstract

In order to improve the overall security of networks

a method of making strategies for the network security enhancement based on global attack graphs was proposed.The method calculated the probability of the network states transition by using global attack graphs.On this basis

the security loss of network states and the criticality of security elements were gotten.Finally

security elements were deleted based on maximum criticality first.The analysis of the ex-ample indicates that the enhancement strategies made by the method can improve the overall security of networks

and the operability is better than traditional methods.
