              XMPP Protocol Extensions for Use with IODEF
                      draft-ietf-mile-xmpp-grid-02

Abstract

   This document describes the extensions made to Extensible Messaging
   and Presence Protocol (XMPP) [RFC6120]that enables the use of XMPP as
   a transport protocol for collecting and distributing any security
   telemetry information between and among network platforms, endpoints,
   and most any network connected device.  Specifically, this document
   will focus on how these extensions can be used to transport the
   Incident Object Description Exchange Format (IODEF) information.
