SNMPv3: M2M protocol SNMP with improved security and privacy
SNMP version 3 supports secure communication. Unlike SNMP v1 and v2, it uses username/password authentication and SSL encryption.
SNMP v1 and v2 is based on UDP and does not support any real security.

SNMP version 3 is designed for secure management of networks with many devices. Typical applications include infrastructure monitoring (including the signal quality of microwave links, disk space on servers, battery states in UPS units, etc.).
