层次化网络安全威胁态势量化评估方法

Quantitative Evaluation Method of Hierarchical Network Security Threat Situation

随着网络应用的日益广泛,随之而来的安全问题越来越严峻,系统性的信息安全风险带来的隐患已经得到全社会的共同关注。通过合理使用分层化安全危险状况定量评价方式,能够全面判断网络系统所存在的安全风险,便于建立安全预警对策。通过系统地认识安全危险,可以提供最合理的安全措施。本文分析了层次化安全危险状态定量评价方式,着重阐述了相应的建模方式,对网络安全的科学评估提供了有效的参考方法。

With the increasingly extensive application of network,the security problems are becoming more and more serious.The hidden dangers brought by systematic information security risks have attracted the common attention of the whole society.Through the rational use of layered quantitative evaluation of safety hazard status,we can comprehensively judge the safety risks existing in the network system and facilitate the establishment of safety early warning countermeasures.By systematically recognizing safety hazards,the most reasonable safety measures can be provided.This paper analyzes the quantitative evaluation method of hierarchical security risk state,and focuses on the corresponding modeling method,which provides an effective reference method for the scientific evaluation of network security.
