摘要: 我国互联网面临的安全威胁越来越严重,为提高现有网络的防御能力,有必要研究科学合理的方法来及时评估我国互联网的安全状况。目前国内外在大规模网络安全评估方面还没有比较成熟的方法,将古林法与模糊评判法结合用于网络安全威胁评估,提出了一个基于古林-模糊综合评判的大规模网络威胁评估模型。实验表明,使用该模型能有效评估大规模网络的安全威胁状况。

Abstract: Chinese Internet is facing increasingly serious security threat.In order to enhance the defense capabilities of existing networks,there is great need to study a scientific and rational method to evaluate the security situation of Internet in China timely.However,there has not yet a mature way in large-scale network security assessment at home and abroad.This paper presents a threat evaluation model for large-scale network based on A.J.Klee and fuzzy evaluation method.Experiments show that using this model can effectively assess the security threat status of large-scale network.
