.# Abstract

This document describes the MISP taxonomy format which describes a simple JSON format to represent machine tags (also called triple tags) vocabularies. A public directory of common vocabularies called MISP taxonomies is available and relies on the MISP taxonomy format. MISP taxonomies are used to classify cyber security events, threats, suspicious events, or indicators.

{mainmatter}

Introduction

Sharing threat information became a fundamental requirements on the Internet, security and intelligence community at large. Threat information can include indicators of compromise, malicious file indicators, financial fraud indicators or even detailed information about a threat actor. While sharing such indicators or information, classification plays an important role to ensure adequate distribution, understanding, validation or action of the shared information. MISP taxonomies is a public repository of known vocabularies that can be used in threat information sharing.

Machine tags were introduced in 2007 [@?machine-tags] to allow users to be more precise when tagging their pictures with geolocation. So a machine tag is a tag which uses a special syntax to provide more information to users and machines. Machine tags are also known as triple tags due to their format.

In the MISP taxonomy context, machine tags help analysts to classify their cybersecurity events, indicators or threats. MISP taxonomies can be used for classification, filtering, triggering actions or visualisation depending on their use in threat intelligence platforms such as MISP [@?MISP-P].

Conventions and Terminology

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [@!RFC2119].

Format

A machine tag is composed of a namespace (MUST), a predicate (MUST) and an optional value (OPTIONAL).

Machine tags are represented as a string. Below listed are a set of sample machine tags for different namespaces such as tlp, admiralty-scale and osint.

tlp:amber
admiralty-scale:information-credibility="1"
osint:source-type="blog-post"

The MISP taxonomy format describes how to define a machine tag namespace in a parseable format. The objective is to provide a simple format to describe machine tag (aka triple tag) vocabularies.

Overview

The MISP taxonomy format uses the JSON [@!RFC8259] format. Each namespace is represented as a JSON object with meta information including the following fields: namespace, description, version, type.

namespace defines the overall namespace of the machine tag. The namespace is represented as a string and MUST be present. The description is represented as a string and MUST be present. A version is represented as a unsigned integer MUST be present. A type defines where a specific taxonomy is applicable and a type can be applicable at event, user or org level. The type is represented as an array containing one or more type and SHOULD be present. If a type is not mentioned, by default, the taxonomy is applicable at event level only. An exclusive boolean property MAY be present and defines at namespace level if the predicates are mutually exclusive.

predicates defines all the predicates available in the namespace defined. predicates is represented as an array of JSON objects. predicates MUST be present and MUST at least content one element.

values defines all the values for each predicate in the namespace defined. values SHOULD be present.

predicates

The predicates array contains one or more JSON objects which lists all the possible predicates. The JSON object contains two fields: value and expanded. value MUST be present. expanded SHOULD be present. value is represented as a string and describes the predicate value. The predicate value MUST not contain spaces or colons. expanded is represented as a string and describes the human-readable version of the predicate value. An exclusive property MAY be present and defines at namespace level if the values are mutually exclusive.

values

The values array contain one or more JSON objects which lists all the possible values of a predicate. The JSON object contains two fields: predicate and entry. predicate is represented as a string and describes the predicate value. entry is an array with one or more JSON objects. The JSON object contains two fields: value and expanded. value MUST be present. expanded SHOULD be present. value is represented as a string and describes the machine parsable value. expanded is represented as a string and describes the human-readable version of the value.

optional fields

colour

colour fields MAY be used at predicates or values level to set a specify colour that MAY be used by the implementation. The colour field is described as an RGB colour fill in hexadecimal representation.

Example use of the colour field in the Traffic Light Protocol (TLP):

"predicates": [
    {
      "colour": "#CC0033",
      "expanded": "(TLP:RED) Information exclusively and directly
                   given to (a group of) individual recipients.
                   Sharing outside is not legitimate.",
      "value": "red"
    },
    {
      "colour": "#FFC000",
      "expanded": "(TLP:AMBER) Information exclusively given
                   to an organization; sharing limited within
                   the organization to be effectively acted upon.",
      "value": "amber"
    }...]

description

description fields MAY be used at predicates or values level to add a descriptive and human-readable information about the specific predicate or value. The field is represented as a string. Implementations MAY use the description field to improve more contextual information. The description at the namespace level is a MUST as described above.

numerical_value

numerical_value fields MAY be used at a predicate or value level to add a machine-readable numeric value to a specific predicate or value. The field is represented as a JSON number. Implementations SHOULD use the decimal value provided to support scoring or filtering.

The decimal range for numerical_value SHOULD use a range from 0 up to 100. The range is recommended to support common mathematical properties among taxonomies.

Example use of the numerical_value in the MISP confidence level:

    {
     "predicate": "confidence-level",
     "entry": [
        {
          "expanded": "Completely confident",
          "value": "completely-confident",
          "numerical_value": 100
        },
        {
          "expanded": "Usually confident",
          "value": "usually-confident",
          "numerical_value": 75
        },
        {
          "expanded": "Fairly confident",
          "value": "fairly-confident",
          "numerical_value": 50
        },
        {
          "expanded": "Rarely confident",
          "value": "rarely-confident",
          "numerical_value": 25
        },
        {
          "expanded": "Unconfident",
          "value": "unconfident",
          "numerical_value": 0
        },
        {
          "expanded": "Confidence cannot be evaluated",
          "value": "confidence-cannot-be-evalued"
        }
     ]
     }
