基于关联分析的关键信息系统生存能力评估方法

A Critical Information System Survivability Assessment Method Based on Correlation Analysis

评估关键信息系统的生存能力是大幅提升我国安全防御能力的重要举措。针对关键信息系统,提出了一种基于关联分析的生存能力评估方法,通过综合分析系统面临的威胁、抵抗能力、恢复能力等因素之间的内在联系,量化系统的生存能力,为发现系统短板与安全管理决策提供依据和指导。实验证明了本文方法的有效性和可行性。

Assessing survivability of critical information system is one of the most important approaches to strengthen national network defense. A survivability assessment method is presented for critical information system. By analyzing the correlation relationship of threat,defensive ability and recovery ability,the survivability of system is qualified to find out drawbacks and provide security administration decision. At last,experiments are done to prove the validity and feasibility of this method.
