         Guidelines and Template for Defining Extensions to the
          Incident Object Description Exchange Format (IODEF)

Abstract

   This document provides guidelines for extensions to the Incident
   Object Description Exchange Format (IODEF) described in RFC 5070 for
   exchange of incident management data, and it contains a template for
   Internet-Drafts describing those extensions, in order to ease the
   work and improve the quality of extension descriptions.

1.  Introduction

   In the five years since the specification of IODEF [RFC5070], the
   threat environment has evolved, as has the practice of cooperative
   network defense.  These trends, along with experience gained through
   implementation and deployment, have indicated the need to extend
   IODEF.  This document provides guidelines for defining these
   extensions.  It starts by describing the applicability of IODEF
   extensions, and the IODEF extension mechanisms, before providing a
   section (Appendix A) that contains a template to be the starting
   point for any future Internet-Draft about an IODEF extension.

   This document is designed to give guidance on the extension of IODEF,
   especially for those extension authors who may be new to the IETF
   process.  Nothing in this document should be construed as defining
   policies for the definition of these extensions.

   At publication time, the Managed Incident Lightweight Exchange (MILE)
   working group of the IETF provides a home for work on IODEF
