**Documentation:** https://datatracker.ietf.org/doc/html/rfc3411

SNMPv3 Architecture (RFC 3411-3418) is one of 5 APIs that [SNMP](https://apis.io/providers/snmp/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include SNMPv3, USM, VACM, Security, and Authentication.

The modular SNMPv3 management framework. RFC 3411 defines the SNMP engine, Message Processing Subsystem, Security Subsystem, and Access Control Subsystem; RFC 3414 specifies the User-based Security Model (USM) with authentication and privacy; RFC 3415 specifies the View-based Access Control Model (VACM); RFC 3416 redefines protocol operations; RFC 3417 covers transport mappings; RFC 3418 contains the MIB for SNMPv3 itself. RFC 7860 extends USM with HMAC-SHA-2 authentication protocols.
