Transport Layer Security (TLS) Transport Model
for the Simple Network Management Protocol (SNMP)
Abstract
This document describes a Transport Model for the Simple Network
Management Protocol (SNMP), that uses either the Transport Layer
Security protocol or the Datagram Transport Layer Security (DTLS)
protocol. The TLS and DTLS protocols provide authentication and
privacy services for SNMP applications. This document describes how
the TLS Transport Model (TLSTM) implements the needed features of a
SNMP Transport Subsystem to make this protection possible in an
interoperable way.
This Transport Model is designed to meet the security and operational
needs of network administrators. It supports the sending of SNMP
messages over TLS/TCP and DTLS/UDP. The TLS mode can make use of
TCP's improved support for larger packet sizes and the DTLS mode
provides potentially superior operation in environments where a
connectionless (e.g., UDP) transport is preferred. Both TLS and DTLS
integrate well into existing public keying infrastructures.
This document also defines a portion of the Management Information
Base (MIB) for use with network management protocols. In particular,
it defines objects for managing the TLS Transport Model for SNMP.
