信息系统生存力研究

Research on Information System Survivability

针对信息系统的重要性和其面临的威胁挑战,分析了生存力对信息系统的重要意义。介绍了系统生存力的定义、理论层次、模拟模型及要素等基本概念,分析了信息系统面临的主要威胁,较为全面地介绍了信息系统生存力的内涵、主要指标,对先进的生存力保障机制如威胁识别机制、对抗机制和恢复机制进行了描述,阐述了重新配置和系统改造等生存力设计方法,并提出了深化开展信息系统生存力设计研究的思路,以期为提高我国信息系统的生存力提供支撑。

Aim at the importance and security challenge of information system, analyses system survivability＇s important significance. Introduces basal conception of system survivability, such as the definition, theoretical level, simulation model, elements etc., analyses the main threat facing information system, general introduces information system survivability meaning and main index, introduces advanced survivability guarantee mechanism, like threat identification mechanism, against mechanism and restore mechanism, introduces some survivability design method, such as reconfigure and system alteration, and presents some thoughts of more research on information system survivability design, expects provide support to improve our country＇s information system survivability.
