MISP is not only a software but also a series of data models created by the MISP community. MISP includes a simple and practical information sharing format expressed in JSON that can be used with MISP software or by any other software.

MISP Core Format

The MISP core format is a simple JSON format used by MISP and other tools to exchange events and attributes. The JSON schema 2.4 is described on the MISP core software and many sample files are available in the OSINT feed.

The MISP format is described as Internet-Draft in misp-rfc. The MISP format are described to support the developer or organisation willing to build your own tool supporting the MISP format (as import or export). The standard is built from practical use-cases and the implementation references within the MISP project. The standard is quickly evolving following the MISP implementation.

MISP objects

MISP objects are in addition to MISP attributes to allow advanced combinations of attributes. The creation of these objects and their associated attributes are based on real cyber security use-cases and existing practices in information sharing. MISP objects are standardised under a simple templating format and are automatically available in MISP. A series of relationships are also defined along with the objects which can be used to create relationships between objects.

The objects available can be browsed via the web site or downloaded as PDF or directly via the MISP software.

MISP Taxonomies

Along with the core format, MISP taxonomies provide a set of already defined classifications modeling estimative language, CSIRTs/CERTs classifications, national classifications or threat model classification. The fixed taxonomies provide a practical method to tag efficiently events and attributes within a set of MISP instances where taxonomies can be easily cherry-picked or extended to meet the local requirements of an organization or a specific sharing community. When using MISP, the MISP taxonomies are available and can be freely used based on the community practises.

The taxonomies can be browsed via the web site or downloaded as PDF or via the MISP software.

MISP Galaxy

MISP galaxy is a simple method to express a large object called cluster that can be attached to MISP events or attributes. A cluster can be composed of one or more elements. Elements are expressed as key-values. There are default vocabularies available in MISP galaxy but those can be overwritten, replaced or updated as you wish. Existing clusters and vocabularies can be used as-is or as a template. MISP distribution can be applied to each cluster to permit a limited or broader distribution scheme. Many MISP galaxy clusters are already available like Exploit-Kit, Microsoft Activity Group actor, Preventive Measure, Ransomware, TDS, Threat actor or Tool used by adversaries.

The galaxy can be browsed via the web site or downloaded as PDF or directly via the MISP software.
