理工大学城市学院本科生毕业设计（论文） 网络安全问题的探讨及研究 摘 要 在当今社会，计算机网络安全问题已经变得日常严峻。人类的社会已经进入到了互联网时代、计算机安全问题将直接关系到国家及社会的各个领域的安全和稳定。目前互联网安全事件频繁出现，平均每18秒之内全球内就会发生一起网络安全事件。因此当前阶段之内，我们只有增强网络安全意识、增强防范措施、加强安全管理、加强网络道德，才能最终有效解决计算机网络安全问题。从而最终保证国内网络信息产业的持续稳定发展。 本文首先讨论了安全信息网络的根本性的内涵，描述了其重要性。进一步阐述了网络拓扑的安全设计，包括网络拓扑分析和网络安全性分析等。然后系统的研究网络安全问题的分类，以及防火墙部署等专业问题。本文系统全面的分析了杀毒软件的主要特点，并一一阐述了防火墙部署的选择标准问题，全面系统的探讨了其安全系统的组成要点。最后对今后网络安全的趋势及发展展开了系统全面的分析。 关键词：网络；安全防火墙；RSA算法 Abstract Computer network security issues directly related to the security and stability of a countrys political, military, economic and other fields. Currently hackers rampant, once every 18 seconds on the world hacking incident occurred. Therefore, raising awareness of the importance of network security, and enhance awareness of prevention, strengthening preventive measures is to ensure sustained and stable development of the inforation industry an important guarantee and prerequisite of the enhance. This paper first discusses the connotation of a fundamental change in information network security occurred, described the importance of the need for the development of national information security system and to establish a network security system with Chinese characteristics, and network security management. Further elaborated the safety design of the network topology, including network topology analysis and network security analysis. Then elaborate on the classification and its main technical characteristics of the network firewall security technology, firewall deployment principles and elaborated on the selection criteria from the position firewall firewall deployment. While a brief kind of the exchine of the information classification and RSA encryption algorithm, discusses the composition of its security system. Key words: occurred ; characteristics ;firewall;RSA algorithm 目 录 摘要
