       The Incident Object Description Exchange Format Version 2

Abstract

   The Incident Object Description Exchange Format (IODEF) defines a
   data representation for security incident reports and indicators
   commonly exchanged by operational security teams for mitigation and
   watch and warning.  This document describes an updated information
   model for the IODEF and provides an associated data model specified
   with the XML schema.  This new information and data model obsoletes
   RFCs 5070 and 6685.
