MISP Taxonomies

Taxonomies that can be used in MISP and other information sharing tool and expressed in Machine Tags (Triple Tags). A machine tag is composed of a namespace (MUST), a predicate (MUST) and an (OPTIONAL) value. Machine tags are often called triple tag due to their format.

The following taxonomies can be used in MISP (as local or distributed tags) or in other tools willing to share common taxonomies among security information sharing tools.

Admiralty Scale

The Admiralty Scale (also called the NATO System) is used to rank the reliability of a source and the credibility of an information.

CIRCL Taxonomy - Schemes of Classification in Incident Response and Detection

CIRCL Taxonomy is a simple scheme for incident classification and area topic where the incident took place.

TLP - Traffic Light Protocol

The Traffic Light Protocol - or short: TLP - was designed with the objective to create a favorable classification scheme for sharing sensitive information while keeping the control over its distribution at the same time.

MISP Taxonomies - tools

machinetag.py is a parsing tool to dump taxonomies expressed in Machine Tags (Triple Tags) and list all valid tags from a specific taxonomy.
