# MISP Taxonomies

[![Build Status](https://travis-ci.org/MISP/misp-taxonomies.svg?branch=master)](https://travis-ci.org/MISP/misp-taxonomies)

Taxonomies that can be used in [MISP](https://github.com/MISP/MISP) (2.4) 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.

![Overview of the MISP taxonomies](tools/docs/images/taxonomy-explanation.png)

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.

The following taxonomies are described:

Market operators and public administrations that must comply to some notifications requirements under EU NIS directive.

### [EUCI](./euci) classification

EU classified information (EUCI) means any information or material designated by a EU security classification, the unauthorised disclosure of which could cause varying degrees of prejudice to the interests of the European Union or of one or more of the Member States [as described](http://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32013D0488&from=EN).

### [Europol Incident](./europol-incident)

Information security indicators have been standardized by the [ETSI Industrial Specification Group (ISG) ISI](http://www.etsi.org/technologies-clusters/technologies/information-security-indicators). These indicators provide the basis to switch from a qualitative to a quantitative culture in IT Security Scope of measurements: External and internal threats (attempt and success), user's deviant behaviours, nonconformities and/or vulnerabilities (software, configuration, behavioural, general security framework).

### [TLP - Traffic Light Protocol](./tlp)

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.

### Vocabulary for Event Recording and Incident Sharing [VERIS](./veris)

Vocabulary for Event Recording and Incident Sharing is a format created by the [VERIS community](http://veriscommunity.net/).

# Reserved Taxonomy

The following taxonomy namespaces are reserved and used internally to MISP.

- [galaxy](./galaxy/) mapping taxonomy with cluster:element:"value".

# How to contribute your taxonomy?

It is quite easy. Create a JSON file describing your taxonomy as triple tags (e.g. check an existing one like [Admiralty Scale](./admiralty-scale)), create a directory matching your name space, put your machinetag file in the directory and pull your request. That's it. Everyone can benefit from your taxonomy and can be automatically enabled in information sharing tools like [MISP](https://www.github.com/MISP/MISP).

For more information, "[Information Sharing and Taxonomies Practical Classification of Threat Indicators using MISP](https://www.circl.lu/assets/files/misp-training/3.2-MISP-Taxonomy-Tagging.pdf)" presentation given to the last MISP training in Luxembourg.

# How to add your private taxonomy to MISP

~~~~shell
$ cd /var/www/MISP/app/files/taxonomies/
$ mkdir privatetaxonomy
$ cd privatetaxonomy
$ vi machinetag.json
~~~~

Create a JSON file Create a JSON file describing your taxonomy as triple tags.

Once you are happy with your file go to MISP Web GUI taxonomies/index and update the taxonomies, the newly created taxonomy should be visible, now you need to activate the tags within your taxonomy.

# MISP Taxonomies - tools

[machinetag.py](./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.

~~~~shell
% cd tools
% python machinetag.py

        admiralty-scale:source-reliability="b"
        admiralty-scale:source-reliability="c"
        admiralty-scale:source-reliability="d"
        admiralty-scale:source-reliability="e"
        admiralty-scale:source-reliability="f"
        admiralty-scale:information-credibility="1"
        admiralty-scale:information-credibility="2"
        admiralty-scale:information-credibility="3"
        admiralty-scale:information-credibility="4"
