数据网络安全的评价技术
信息化和网络化是当今S界经济与社会发展的大趋势，信息资源的深入开发利用以及各行各业的信息化、网络化己经敏捷打开;全社会广泛使用信息技术，计算机域网络广泛使用为大家所重视。但与此同时，网络安全技术在大家的现实生活中有着广泛的使用。本论文要点研究很多安全技术中的防火墙技术，对防火墙技术做了全面的研究。第二章扼要介绍了网络安全的研究布景和基础，为今后各章做准备，对网络安全技术的基本知识进行了较为详细的评论。介绍了网络安全的研究目标及其等级。第三章，侧重介绍了防火墙技术概念、类型以及防火墙技术的系统结构及其关键技术，最终分析了防火墙技术的缺乏。?在论文最终给出了信息安全方面首要的技术。(Informatization and networking are the general trend of economic and social development in the world today. The in-depth development and utilization of information resources and the informatization and networking of all walks of life have been rapidly opened; information technology is widely used in the whole society, and computer domain networks are widely used. Everyone pays attention. But at the same time, network security technology is widely used in everyone's real life. The main point of this paper is to study the firewall technology in many security technologies, and make a comprehensive study of the firewall technology. The second chapter briefly introduces the research background and foundation of network security, prepares for future chapters, and reviews the basic knowledge of network security technology in detail. The research objectives and levels of network security are introduced. The third chapter focuses on the concept and types of firewall technology, the system structure and key technologies of firewall technology, and finally analyzes the lack of firewall technology. ?In the end of the paper, the primary technology in information security is given.)
