        IODEF-extension for structured cybersecurity information
                       draft-ietf-mile-sci-13.txt

Abstract

   This document extends the Incident Object Description Exchange Format
   (IODEF) defined in RFC 5070 [RFC5070] to exchange enriched
   cybersecurity information among security experts at organizations and
   facilitates their operations.  It provides a well-defined pattern to
   consistently embed structured information, such as identifier- and
   XML-based information.
