What is SNMP ?
Stands for Simple Network Management Protocol and is used for monitoring and status informationon a network. SNMP can be used to monitor any device that is SNMP capable and this can includecomputers, printers, routers, servers, gateways and many more using agents on the target systems. Theagents report information back to the management systems by the use of “traps” which capture snapshotdata of the system. This trap information could be system errors, resource information, or otherinformation. The SNMPv2 standard includes enhancements to the SNMPv1 SMI-specific data types, such asincluding bit strings, network addresses, and counters. In SNMPv3 security was addressed. Because all ofthe trap information sent was in clear text, any monitoring information being sent and collected foroperational purposes could also be pulled off the wire by a malicious person
