SNMP defines that how the information is exchanged between the management applications and the agents. It is used to manage the network performance, to find and solve the network problems and to plan the network growth. SNMP uses five messages like GET, GET-NEXT, GET-RESPONSE, SET, and TRAP to manage the devices and to communicate with the SNMP agent and SNMP Manager. It is simply a request-response protocol. The network management system issues request and the network devices send responses. SNMP agents can be setup to notify the network management stations.
SNMP lacks the authentication procedures, which results in the security threats and vulnerabilities. This includes the modification of information, timing modification, disclosure and masquerading occurrences. SNMP security settings can be configured as mentioned below.
