Introducing TAXII 2.1 and a fond farewell to the TAXII 2.0 Server
Brief
As mentioned in our 2024 Roadmap and the v15 release blog , we’re excited to introduce our new TAXII server and the latest addition to the ATT&CK Workbench software suite: the MITRE ATT&CK Workbench TAXII 2. 1 Server . We’ve open-sourced the TAXII 2. 1 code on GitHub , allowing you to set up your own servers within your organization and contribute to its improvement.
While you’re diving into the new 2. 1 server, don’t forget: our TAXII 2. 0 server is retiring on December 18.
To continue receiving updated ATT&CK data, you’ll need to migrate from cti-taxii. mitre. org to attack-taxii. mitre. org. However, this migration may involve more than just a URL change. Given the transition from STIX 2. 0 to STIX 2. 1, the complexity of your migration will depend on how deeply your applications are integrated with STIX 2. 0.
