    IODEF-extension to support structured cybersecurity information
                       draft-ietf-mile-sci-05.txt

Abstract

   This document extends the Incident Object Description Exchange Format
   (IODEF) defined in RFC 5070 [RFC5070] to exchange enriched
   cybersecurity information among cybersecurity entities and facilitate
   their operations.  It provides the capability of embedding structured
   information, such as identifier- and XML-based information.
