摘要
DHCP的优点是具有强有力的动态IP地址分配机制;其缺点是没有任何安全认证机制系统就很容易受到攻击,给网络安全与网络管理带来隐患。针对DHCP存在的缺陷,设计了一种外部访问控制机制,用外部的认证来弥补这个不足。在简要介绍访问控制的概念后,给出一套具体的设计方案,即DHCP外部访问控制的方法。
DHCP is famous or its robust dynamic IP address configuration mechanism. But DHCP is lacking of safety authentication and easily attacked, which is a hidden trouble for network safety and management. The author designs an external visited control mechanism to remedy the shortcomings. The conception of visited control is given. Then it presents a set of practical scheme--DHCP external visited control.
