Abstract

   The Incident Object Description Exchange Format v2 [RFC7970] defines
   a data representation that provides a framework for sharing
   information commonly exchanged by Computer Security Incident Response
   Teams (CSIRTs) about computer security incidents.  Since the IODEF
   model includes a wealth of available options that can be used to
   describe a security incident or issue, it can be challenging for
   security practitioners to develop tools that can leverage IODEF for
   incident sharing.  This document provides guidelines for IODEF
   implementers.  It also addresses how common security indicators can
   be represented in IODEF and use-cases of how IODEF is being used.
   This document aims to make IODEF's adoption by vendors easier and
   encourage faster and wider adoption of the model by Computer Security
   Incident Response Teams (CSIRTs) around the world.
