摘要
SNMP代理端维护着被管设备的管理信息库(MIB),为有效控制网管站对MIB库的访问,SNMP对外采取了对来访的网管用户进行身份验证的措施,对内借用了数据库管理中视图的概念,用以限制不同身份的用户可访问的管理信息。本文纵向论述了SNMP安全机制的实现,其中着重阐述了SNMPv3的实现机制。
SNMP Agent maintains the Management Information Base（MIB）,in order to control effectively the network manager to visit managed objects in the MIB,SNMP authenticates the identity of the users,and introduces the concept of view originated from Database to give different users different accessible subset of the MIB,This paper demonstrates the implementation of security mechanism in the three versions of SNMP, especially in SNMPv3,
