计算机网络安全体系结构及其技术

侧重于技术层面，从网络安全的基本概念出发，具体阐述了国外主流网络安全体系结构，对网络安全面临的威胁进行具体分析，在讨论了保证网络安全技术的基础上，提了一些网络安全问题所对应的技术解决办法。最后提出了网络安全体系结构应该是融合了技术和管理在内的一个可以全面解决安全问题的体系结构作为本文的结束语。

Architecture & Technology for Security of Computer NetWork

The emphasis of this article is technology. So working with the basic ideas of security about network, we have illustrated some types of prevalent architecture of network security from forgien country. With analysing the threats to security of network practically and discussing technology for network, we improve a few ways to solve some security problems. At the end we give a safe architecture, which considers technology and management together. So we use this architecture that can solve security problems comprehensively as a end for this article.
