一种量化的网络安全态势评估方法

a approach for evaluating security situation of network system

本文根据网络中系统运行信息和系统配置信息,运用故障树模型对网络安全态势进行分层量化评估。经实验证实该评估方法能够较准确的反映网络安全运行态势。

In this paper, a novel approach for evaluating security situation is proposed. In this approach, system tuning information and system configuration information are used. In addition, the fault tree model is also adopted in order to describe the network security situation of a whole enterprise network in different layers such as service level, host level and network level. Experiment resulets show that this mehod can evaluate network security situation precisely
