网络安全体系结构的设计与实现

随着计算机网络的发展,网络安全也已成为网络建设的重大对策问题.该文首先说明网络安全的必要性,并在所提出的一种网络安全系统设计框架的基础上,对其中的网络安全体系结构设计与实现进行了详细的分析,给出了体系结构模型和策略管理执行模型,详述了其设计过程,把安全体系结构、安全策略管理的实现和网络安全的实现机制有机地结合在一起,保证从高级安全策略向网络安全实现机制的平滑过渡.

The Design and Implementation of Network Security Architecture

With the development of computer network, network security has also become an important issue. The necessary of network security was first developed and based on a framework for network security system design put forwarded, detailed analysis of the phase of network security design is made in this paper, and arehitecture model and policy management implemented model and proeess of design are given, which hangs security architecture, security policy implement and the enforced mechanism of network security together,and insures the transition between high - level ecurity requirement analysis and the low- level system implementation smoothly.
