Internet Engineering Task Force (IETF) W. Hardaker Request for Comments: 5953 SPARTA, Inc. Category: Standards Track August 2010 ISSN: 2070-1721 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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.
