【摘要】：自上世纪90年代至今,电子政务的发展可谓日新月异,突飞猛进。随着网络技术和电子商务等新型通讯技术的不断兴起和改进,全世界各级政府部门也逐渐从完全的人工化走向智能化高精尖技术化,由此催生了电子政务这一新型事物。它作为电子信息技术与管理的有机结合,成为当代信息化的最重要的领域之一。目前,全球范围内的电子政务网络四通八达,随之而来的就是关于电子政务网络安全问题。本文通过对电子政务系统网络中的主机程序中会出现的如黑客入侵、数据资源窜改或丢失、信息资源遭窃听或修改等安全问题进行分析与研究,并提出电子政务系统网络安全的综合处理方案。从电子政务系统网络的安全进行分析,之后对电子政务网络安全解决方案进行分类研究,分别研究了防火墙技术,数据包过滤技术,数据加密技术,数字签名技术,PKI,SSL协议,入侵检测技术等。作为一个研究应用工程实例,通过对抚顺县城建局电子政务信息网络的风险分析及安全需求分析,对其网络安全的整体解决方案进行详细设计。工程分别做了访问控制设计,物理安全设计,通信机密设计,入侵检测设计,病毒防护设计,备份恢复设计以及安全管理设计等,以期为抚顺县城建局电子政务工作的有效开展提供理论依据。本文的工作内容为:(1)对现有的网络安全技术进行研究,总结出最适合城建局电子政务系统网络安全的技术方案。(2)对电子政务系统的网络安全进行需求分析,分别从可行性分析,模块需求,功能需求等方面来分析。(3)对抚顺县城建局电子政务系统的网络安全系统进行总体设计和详细设计。(4)对抚顺县城建局电子政务网络安全系统进行设计与实现。最后,通过分析国内外网络安全研究现状,分析现有网络的不足,缺点和漏洞,得出开发电子政务网络安全系统的必要性的结论。本文先从工程的需求出发,通过需求分析和系统设计得出系统的整体架构,之后再对系统进行详细的设计,得到每一部分的设计思路,最后对每一个模块分别的实现其功能。此外,还要在适当的环境中对系统进行测试,进而完善系统。
[Abstract]:Since the 1990 s, the development of e-government can be described as rapid and rapid progress. With the rise and improvement of new communication technology, such as network technology and electronic commerce, all levels of government departments in the world have gradually changed from completely artificial to intelligent and sophisticated technology, thus giving birth to e-government, a new kind of thing. As an organic combination of electronic information technology and management, it has become one of the most important fields of modern information technology. At present, the network of e-government all over the world, followed by the issue of e-government network security. In this paper, we analyze and study the security problems such as hacker intrusion, data resource tampering or loss, information resource eavesdropping or modifying, which will appear in the host program in the network of e-government system. And put forward the comprehensive processing scheme of network security of e-government system. This paper analyzes the network security of E-government system, then classifies the security solutions of E-government network, and studies the firewall technology, packet filtering technology, data encryption technology, digital signature technology and PKI / SSL protocol, respectively. Intrusion detection technology. As an example of research and application, through the risk analysis and security requirement analysis of the E-government information network of Fushun City Construction Bureau, the overall solution of its network security is designed in detail. The project has made access control design, physical security design, communication secret design, intrusion detection design, virus protection design, backup and recovery design and security management design, etc. In order to provide theoretical basis for the effective development of e-government work of Fushun City Construction Bureau. The content of this paper is: (1) researching the existing network security technology, summing up the most suitable technical scheme for the network security of the city construction bureau e-government system. (2) analyzing the demand of the network security of the e-government system, respectively from the feasibility analysis The overall design and detailed design of the network security system of Fushun City Construction Bureau E-government system are analyzed from the aspects of module requirement and function requirement etc.) the network security system of Fushun City Construction Bureau is designed and implemented. Finally, by analyzing the current situation of network security research at home and abroad, analyzing the shortcomings, shortcomings and loopholes of the existing network, the paper draws the conclusion that it is necessary to develop the network security system of e-government. Based on the requirements of the project, the whole structure of the system is obtained through the requirement analysis and system design, and then the detailed design of the system is carried out, and the design ideas of each part are obtained. Finally, the function of each module is realized separately. In addition, in the appropriate environment to test the system, and then improve the system.
