Windows下基于IMD的NAT型防火墙的设计

Design and Implement of NAT Firewall Based on IMD in Windows

在防火墙技术中,单独使用一种技术总会出现性能瓶颈或安全隐患的问题,综合利用多种技术制作的防火墙能够满足需要高标准网络安全的环境.通过模块化的设计方法,在Windows网络体系结构的IMD层下把NAT技术、过滤技术、状态检测技术,以及不同的认证方法结合起来实现防火墙,以达到高效抵御各种网络攻击,极大提高网络安全性的目的,并且这种方法实现容易,更新方便.

Among the technologies of firewall, exploiting a single technology of firewall will result in the bottleneck of performance and the potential safety hazard. The firewall made of many technologies can meet the requirement of high-standard firewall. In the environment of Windows Intermediate Protocol Driver, we can easily incorporate Network Address Transfer, packet filtering, link state detecting and various authentication methods into firewall by modularization design procedures. This firewall can effectively resist all sorts of network attacks, promote network security dramatically and can be implemented easily and updated conveniently.
