网络准入技术的发展与展望

The developments and predictions in network admission control technology

网络安全事件的源头产生于内网的情况越来越多,保障内网安全的前提和基础是网络准入技术。目前,实现网络准入有多种方法,从这些方法出发,不同的IT厂商各自推出了不同的实现方案。本文通过研究认为,这些方法与方案还在不断完善中。网络准入技术今后的发展方向将是适应各种不同的网络环境,以及在准入过程中实现灵活的网络安全控制策略。

As the attracks from network inside is more than from network outside,network admission control technology become the precondition of network security.In this paper,we have reviewed the developments of methods of network admission control technology and the plan from main IT companys.We think network admission technology should adapt the different network enviromental,and realize the flexible policy in network admission control process.
