局域网接入层安全保障技术应用

Application of LAN Access Layer Safety Guanrantee Technology

根据拓扑结构,可以将局域网分为主干层、汇聚层和接入层三个层次。接入层是最终面向用户的,是局域网用户进入网络的第一个接入点,在该层应用保障安全的策略,能为局域网安全运行提供保障。本文介绍了生成树增强特性、信任与身份认证、威胁防御等相关技术在接入层的应用,为构建一个安全可靠的局域网提供技术支持。

According to the topology structure, we can divide the LAN into three layers-arterial layer, converging layer and access layer. The access layer is facing the users finally and the first access point for the users to enter into the network. So we apply the safety guarantee technology in this layer will supply a guard for the LAN to nm in security. This article introduces the application of some techniques to supply a technology support for buiding a safe and reliable LAN.
