摘要
分析了对安全性进行定量评估的必要性和可行性,基于概率论和数理统计,给出了一个安全评估的量化模型。并通过模块分解提出了一种定量评估系统安全性的方法,最后结合实例对定量评估技术进行了有意义的研究与尝试,验证了上述体系的合理性与有效性。
In this paper, the necessity and feasibility of quantitative security evaluation are analyzed, in particular with regard to nowadays security requirements. Based on the probability and statistics, the quantitative security model is brought forward. And then a complete quantitative evaluating system is introduced, which is based on the modularization and the quantitative security model. Finally, the rationality and validity of this system are verified through experiments.
