The Realization of SNMP Agent’s Security Module and Multi-manager Access Algorithm WANG Zhendong,SUN Minghai (Electronic Engineering Dept., Tsinghua Univ., Beijing 100084) Abstract:As networks increase in size and complexity, SNMP has being the most important management protocol in the multi-vendor environment. However, SNMP is considered that there exist limitations with its security and distributed management capability. To provide SNMP more enhancement,this paper presents a security module and a multi-manager access algorithm in the agent side, and makes some analysis at the same time. Key words:SNMP;agent;security;distributed management
