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