SNMP访问控制增强的设计与实现

Design and Implement of Enhanced SNMP Access Control

简单网络管理协议(SNMP)提供了一种监控和管理计算机网络的系统方法.在v3版本的基础上扩展了其访问控制方式,提供包括基于视图以及时间约束特性角色控制的两种访问控制方式,使之具有简单、灵活、表达力强、可用性强等特点.实际应用表明,增强后的SNMPv3在访问控制方面更符合实际需求,使用更方便.

SNMP provides a way to manage and monitor the computer network. By extending its access control model on the 3^rd version, the paper offers two methods ： view based access control model（vacm） and role based access control model. It enhances RBAC＇s power and function. In use SNMPv3 based on Time Enhanced RBAC is more efficient and useful.
