基于模糊模型的网络社会场系统的安全评估

摘要

Network is a virtual world where all behaviors can be used to cover up the virtual identity, so it is easy to breed fraud and other illegal phenomena. More and more network security has aroused widespread con-cern. The existing security assessment methods, applied to most security assessment problems, are simplex framework for security assessment and not targeted at network security, which are used to assess security from the technical, functional and mechanism perspectives. Based on soft structure of sociology, this paper proposes social network field system theory, divides social network into levels according to procedures in the theory of so-cial network field system. By combining unique nature of the social network security, based on the fuzzy mathe-matical mode, it conducts the network security assessment in view of the network structure and integrity.%网络是个虚拟的世界,所有行为都可以用虚拟的身份进行,所以容易滋生诈骗等违法现象,网络安全引起了人们的普遍关注.现有的网络安全评估方式可以应用于大多数问题的安全风险测评,都是单一的的安全评估框架,对于网络安全的评估没有针对性,并且这些方法更多的是从安全技术、功能和机制的角度来进行评估.文章基于社会软结构学提出了网络社会场系统理论,并按照网络社会场系统论工作的步骤进行分层,结合网络社会安全特有的性质从社会学的角度出发建立模糊数学模型来评估网络社会场系统的安全等级,从网络社会的结构化与完整性的新视角进行网络安全评估.
