Abstract: SNMPv3, tbe latest network management protocol, came into being in 1998. Security of network management is one of the main issues it cares. SNMPv3 employs MAC, time stamp, encryption and access control to secure network management. This paper describes its primary threats and introduces its security mechanisms. Then the paper analyzes security of SNMPv3 from different aspects such as algorithm and key management. Finally, the paper points out potential security problems and issues that need noticing in implement.Also corresponding proposals are put forward.
