基于VaR-Copula的信息安全评价模型研究

近年来,我国信息安全面临的形势越来越严峻,而作为信息安全风险防范的最基础手段——风险评价理论和方法还没有得到有效发展和真正发挥作用.研究在深入分析信息安全风险理论基础上,采用VaR理论和Copula法,构建了一种信息安全评价模型,得到了从整体上来把握和衡量信息安全的VaR指标,解决了现有研究主要集中于构建指标体系及其基础上评价模型的弊端.最后,并采用实例验证了该模型的有效性.

Research on Information Security Risk Evaluation Based on VaR-Copula

In recent years,China’s information security has been facing severe situation. As the most basic risk prevention tools of information security,the information security risk assessment theory and methods has not been effectively developed and really work.In this study,with in-depth analysis of information security risks,the VaR theory and Copula method were used to build an information security evaluation model,to get up from the grasp of the overall information security VaR measure indicators.It solved the disadvantages of the existing research has focused on build index system and evaluation method.Finally, using examples verify the model effectiveness.
