                            MISP core format
                   draft-dulaunoy-misp-core-format-09

Abstract

   This document describes the MISP core format used to exchange
   indicators and threat information between MISP (Malware Information
   and threat Sharing Platform) instances.  The JSON format includes the
   overall structure along with the semantic associated for each
   respective key.  The format is described to support other
   implementations which reuse the format and ensuring an
   interoperability with existing MISP [MISP-P] software and other
   Threat Intelligence Platforms.
