              Using XMPP for Security Information Exchange
                      draft-ietf-mile-xmpp-grid-10

Abstract

   This document describes how to use the Extensible Messaging and
   Presence Protocol (XMPP) to collect and distribute security incident
   reports and other security-relevant information between network-
   connected devices, primarily for the purpose of communication among
   Computer Security Incident Response Teams and associated entities.
   To illustrate the principles involved, this document describes such a
   usage for the Incident Object Description Exchange Format (IODEF).

1.  Introduction

   This document defines an architecture, i.e., "XMPP-Grid", as a method
   for using the Extensible Messaging and Presence Protocol (XMPP)
   [RFC6120] to collect and distribute security incident reports and
   other security-relevant information among network platforms,
   endpoints, and any other network-connected device, primarily for the
   purpose of communication among Computer Security Incident Response
   Teams and associated entities.  In effect, this document specifies an
   Applicability Statement ([RFC2026], Section 3.2) that defines how to
   use XMPP for the exchange of security notifications on a controlled-
   access network among authorized entities.

   Among other things, XMPP provides a publish-subscribe service
   [XEP-0060] that acts as a broker, enabling control-plane functions by
   which entities can discover available information to be published or
