基于等级保护的地方政府网络信息安全告警设计研究

Research on Notification Alert Design of the Local Governments Network Information Security Based on Hierarchical Protection

政府网络是在物理通信网络连接的基础上,采用符合Internet技术标准的面向政府机关服务的网络,分为政务内网、外网、WEB网站。政府网络信息安全告警体系建设是具有战略性意义的项目,它的实施对政府机构转变管理职能和工作方式,提高服务管理水平,打造24小时服务型政府、建设高效规范的工作机制产生重要的影响。地方政府网络信息安全告警结合等级保护制度,采用人工神经网络计算模型及建立贝叶斯网络,并运用大规模并行处理和自学习自组织非线性动力学方法,探索出一套统一归一化的、具备五级告警机制的、可量化分析的政府网络信息安全告警体系。

The local governments network is a government agencies service-oriented network, which uses inter- net technical standards based on physical communication network connection. It consists of government internal network, external network and WEB sites. The construction of the governments network information security sys- tem is a project with strategic significance. Implementation of the system plays a key role in transformation of management functions and working styles, improvement of service management and development of a 24 hour- service-oriented government and high efficient and standard mechanism. By combining hierarchical protection system, using artificial neural networks computation model, developing Bayesian networks, and applying large- scale parallel processing and nonlinear dynamical methods of self-study and self-organization, a unified and nor- malized governments network information security system with five-level notification alert mechanism and indica- tive quantitative analysis is developed
