Analysis on the security of MIB objects defined in network device

SNMP is currently the most widely used network management protocol which can examine the condition of network equipment and control them through visits MIB objects. It makes the network more convenient to manage while brings about new security challenges. Based on the analysis of the security threats brought by SNMP and the ways to attack a network through SNMP protocol, this paper designs several ways to analyze the security of MIB objects defined in a network device. At last it puts forward some corresponding security enhancement measures for management of SNMP, such as password setting, function selecting, software updating and proper SNMP configuring, etc. This article can be the reference of enhancing the security of the network managed by SNMP protocol.
