Using Extensible Messaging and Presence Protocol (XMPP)
for Security Information Exchange
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).

RFC 8600 XMPP Grid June 2019
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
