Simple Network ManagementProtocol (SNMPv3) is largely based on SNMPv2 and offers modularity with standardized individual elements. It is characterized by its simplicity and above all its security and can be configured remotely. In the architecture of SNMPv3, the User-based Security Model (USM) is introduced, as well as the View-based Access Control
Model (VACM). The SNMPv3 architecture supports the simultaneous operation of different security, access and message processing models. SNMPv3 is described as a draft standard in RFCs 2271 to 2275 and in RFC 3410.
