摘要
分析了网络熵在计算机防护攻击中的应用。在网络安全指标选取基础要求的前提下,分析基于网络熵效果评估,量化指标,得到安全性度量,构建定量评估模型,系统设置子模块包括基本参数、攻击目的以及服务类型。采用灰色关联度表示评价指标,利用Libpcap库函数进行数据采集,设计系统实现框架图。搭建安全评估系统,发动模拟攻击,验证效果评估模型有效性,计算机防护攻击评估模型能够反应网络攻击效果。计算机防护攻击模型能够定量评估网络攻击效果,可操作性强。
The application of network entropy in computer anti-attack is analyzed. On the premise of the basic requirement of network security indicator selection,the effect evaluation based on network entropy and quantitative index are analyzed to obtain the security metric. The quantitative evaluation model was constructed,in which the submodule of system setup is composed of basic parameters,attack purpose and service types. The framework diagram of the design system was implemented by taking gray correlation degree to express the evaluation index and using Libpcap library function to acquire the data. The security assessment system was built,and a simulation attack was launched to verify the validity of the effect evaluation model. The computer anti- attack evaluation model can react and quantitatively evaluate the network attack effect. The model has strong operability.
