This taxonomy was designed with the aim of enabling desired sharing and preventing unwanted sharing between Thales Group security communities.

Install the Thales Group Taxonomy

The Thales Group Official taxonomy is now installed by default in MISP v2.4.146. For versions prior to v2.4.146, please install the taxonomy as described here.

[MANDATORY] Activate the taxonomy

  • Doucle click on the thales_group taxonomy
  • Click on (enable)
  • Go back to taxonomies/index
  • Click on (enable all)
  • Check Required checkbox (required for Event publication):
    • When publishing an Event, you will be required to use at least one TAG from the Thales Group taxonomy.

We also recommend to activate the TLP Taxonomy.

[MANDATORY] Filter Event publication using the taxonomy

Go to MISP Web GUI /servers/index and click on Edit icon on the MISP Thales Group Internal Server.

Then, modify the Push rules:

  • Add to Blocked Tags (AND NOT):
    • thales_group:tlp:black
    • tlp:red
    • thales_group:distribution="team_eyes_only"
  • Add to Allowed tags (OR):
    • thales_group:distribution="limited_distribution"
    • thales_group:distribution="external_alliances"
    • thales_group:distribution="customers"
    • thales_group:minarm
    • thales_group:acn
    • thales_group:sigpart
    • thales_group:to_block

[Required for versions prior to v2.4.146] Install from scratch

cd /var/www/MISP/app/files/taxonomies/
mkdir thales_group
cd thales_group

Copy the thales_group/machinetag.json file:

curl https://raw.githubusercontent.com/MISP/misp-taxonomies/main/thales_group/machinetag.json -o machinetag.json

Go to MISP Web GUI taxonomies/index and click on Update Taxonomies. The newly created taxonomy should be visible.

Usage

When using this Taxonomy, first, you need to be the more restrictive possible. Then, allow the sharing to the Thales Group Community or to specific entities.

Example:

When creating an Event:

  • Put the Event Distribution to Your organisation only
  • Select the TAG thales_group:distribution="team_eyes_only" from the Thales Group Taxonomy.

When you want to share the Event to the Thales Group Community ONLY:

  • Put the Event Distribution to All communities
  • Remove the TAG thales_group:distribution="team_eyes_only"
  • Select the TAG thales_group:distribution="limited_distribution"
  • Publish the Event
