 Datagram Transport Layer Security (DTLS) Transport Mapping for Syslog

Abstract

   This document describes the transport of syslog messages over the
   Datagram Transport Layer Security (DTLS) protocol.  It provides a
   secure transport for syslog messages in cases where a connectionless
   transport is desired.
