【摘要】：随着信息技术广泛应用和互联网的迅猛发展，国民经济和社会信息化水平的高低已经成为衡量一个国家综合实力的重要标志。政府作为信息资源的最大拥有者理应成为信息社会的中心节点。电子政务成为推动国家信息化发展的重要力量，建设电子政府，开展电子政务无疑具有重要的理论价值和实践意义。电子政务将政府的机构管理和服务职能转移到网络上去完成，同时实现政府组织结构和工作流程的重组优化，超越时间、空间和部门分隔的制约，向全社会提供高效优质、规范透明和全方位的管理与服务。要充分发挥和展现电子政务信息网的特点和优势，最基本的要求就是确保政务网络安全可靠地运行。电子政务系统就政府转变职能、提高办事效率，建立公开、透明、科学、廉洁、高效的行政办事决策的重要手段。电子政务信息网同时又是一个相对独立的、信息的内外网分别交流但又与外部密切联系的专用信息系统，恶意攻击或无意泄密可来自内部和外部，正是由于电子政务信息网的特殊性质决定了系统网络的安全性显得尤为重要。本文从电子政务的基本概念、电子政务发展的现状、电子政务存在的问题出发，针对我国电子政务建设过程中存在的主要问题进行了分析,并提出了相应的对策,还借鉴了其他一些电子政务建设比较完善的国家经验,对电子政务的发展前景进行了积极地展望。为适应电子政务大发展大繁荣的需要，在构建电子政务信息网时必须高度重视其安全需求，积极完善安全防护策略，保障其优质高效、安全畅通的运行。本文首先通过研究和分析我国电子政务信息网发展历程和安全现状，提出电子政务信息网安全防护的概念；其次从多个角度探究了我国电子政务信息网络目前面临的主要安全威胁问题和发展瓶颈，阐述了建立电子政务信息网管理中心的重要意义和管理原则；再次依据信息安全管理的模型和标准，本论文从风险分析、安全标准、管理原则三方面解释了电子政务信息安全管理体系的基本模型；复次结合我国电子政务信息网的建设特点、发展现状等情况，描述了安全防护策略的相关内容，并有针对性地提出一系列的安全管理实践措施，从物理安全、访问控制、通信加密、数据备份、安全审计等方面对电子政务信息网的安全体系进行了分类研究;最后,作为一个研究应用工程实例，对典型的电子政务信息网络的安全方案进行了详细介绍。本文研究的电子政务信息网安全整体解决方案，对于保证电子政务系统的保密性、完整性、可用性、可控性、可审性等方面具有重要意义，，对于其他城市的电子政务系统建设实践也有一定的参考指导意义。
[Abstract]:With the wide application of information technology and the rapid development of the Internet, the level of national economy and social informatization has become an important symbol to measure the comprehensive strength of a country. Government as the largest owner of information resources should become the central node of the information society. E-government has become an important force to promote the development of national informatization. It is undoubtedly of great theoretical value and practical significance to build e-government and develop e-government. E-government transfers government organization management and service functions to the network to complete, and at the same time realizes the reorganization and optimization of government organizational structure and workflow, surmounts the constraints of time, space and division, and provides the whole society with high efficiency and high quality. Standardize transparent and comprehensive management and service. To give full play to the characteristics and advantages of E-government information network, the most basic requirement is to ensure the safe and reliable operation of E-government network. E-government system is an important means for the government to change its functions, improve its efficiency, and establish an open, transparent, scientific, clean and efficient administrative decision-making method. E-government information network is at the same time a relatively independent information network, the internal and external information exchange, but also closely related to the outside of the private information system, malicious attacks or inadvertent leaks can come from inside and outside, It is because of the special nature of e-government information network that the security of system network is very important. Starting from the basic concept of E-government, the present situation of E-government development and the problems existing in E-government, this paper analyzes the main problems in the process of E-government construction in China, and puts forward the corresponding countermeasures. It also draws lessons from other countries' experiences in the construction of e-government, and makes a positive prospect for the development of e-government. In order to meet the needs of the great development and prosperity of e-government, we must attach great importance to the security requirements of E-government information network, actively improve the security protection strategy, and ensure its high quality, high efficiency, safe and smooth operation. Firstly, this paper puts forward the concept of security protection of E-government information network by studying and analyzing the development course and security status of E-government information network in China. Secondly, this paper probes into the main security threats and the bottleneck of the development of the E-government information network in China from several angles, and expounds the significance and management principle of establishing the E-government information network management center. Thirdly, according to the model and standard of information security management, this paper explains the basic model of e-government information security management system from three aspects: risk analysis, security standard and management principle. Based on the characteristics and current situation of E-government information network construction in China, this paper describes the relevant contents of security protection strategy, and puts forward a series of practical security management measures, from physical security, access control, etc. The security system of E-government information network is classified and studied in the aspects of communication encryption, data backup, security audit and so on. Finally, as an example of research and application, The security scheme of typical e-government information network is introduced in detail. The whole security solution of e-government information network studied in this paper is of great significance to ensure the confidentiality, integrity, usability, controllability and reviewability of e-government system. For other cities, the construction of e-government system practice also has a certain reference significance.
