【摘要】 当前已有的信息系统风险评估方法,关注于对组成系统的各个组件的安全性分析,但是缺少对系统安全特性的整体把握。随着复杂网络理论研究的日渐成熟,越来越多的研究者利用复杂网络理论来解决现实系统的结构分析问题。本文将复杂网络理论应用到复杂信息系统的结构性风险分析领域,通过对信息系统网络的连通性和功效性两个方面的分析,实现了对复杂信息系统结构脆弱性分析。本方法通过对信息网络系统特有的网络流量特征研究,弥补了通用复杂网络理论对网络功效性评价的片面性,同时填充了对信息系统结构整体脆弱性分析的空白。更多还原

【Abstract】 The existing information systems risk assessment methodologies which concern about the safety analysis of the various components of the system, are lacking in grasp of the overall system security features. With the maturing of complex network theory, more and more researchers take advantage of this theory to solve structural analysis problems of reality system. In this article, the complex network theory has been applied to the field of structural risk analysis of complexity information systems. In order to analyses structural vulnerability of complex information systems, there do some research on connectivity and efficacy of the Information systems network. By study of the network traffic, which is the unique characteristic of information network system, this method makes up for the one-sidedness of the Universal complex network theory in evaluate efficacy of network. At the same time, it fills the blank in research of overall structure vulnerability of the information system.更多还原
