OASIS Members and other interested parties,
We are pleased to announce that TAXIIâ Version 2.1 csprd02 from the OASIS Cyber Threat Intelligence (CTI) TC  is now available for public review and comment. This is the second public review for these titles.
Trusted Automated Exchange of Intelligence Information (TAXII) is an application layer protocol used to exchange cyber threat intelligence (CTI) over HTTPS. It enables organizations to share CTI by defining an API that aligns with common sharing models.
TAXII is specifically designed to support the exchange of CTI represented in STIX. As such, the examples and some features in the specification are intended to align with STIX. This does not mean TAXII cannot be used to share data in other formats; it is designed for STIX, but is not limited to STIX.
The documents and related files are available here:
