接入控制器安全网络管理系统的设计与实现

Design and Realization of a Security Network Management System Based on Access Controller

在讨论了接入控制器 (AC)网络管理系统安全重要性的基础上 ,分析了SNMP协议的应用 ,包括对其 3个版本SNMPv1、SNMPv2及SNMPv3的优缺点的对比 ,并解释了该设备网络管理系统采用SNMPv3版本的原因。详细介绍了AC所实现的管理信息库的内容 ,包括RFC1 2 1 3协议、IEEE80 2 .1x协议、RMON协议、Web +DHCP、EAP_OTP、EAP_MD5、EAP_TLS、EAP_SIM等多种认证协议以及网络管理系统的五大功能。

The paper discusses the importance of the security management system based on access controller (AC) at first, then analyzes the application of SNMP protocol, including the advantages and drawbacks of SNMPv1, SNMPv2 and SNMPv3, and gives an application of SNMPv3. Secondly, this paper introduces specifically the realization of MIB, including RFC1213 protocol, IEEE 802.1x protocol, RMON protocol, web+DHCP, EAP_OTP, EAP_MD5, EAP_TLS, EAP_SIM authentication protocol and etc, and the five functions of the security management system. At last, it describes the design and realization of the architecture of the security management system.
