TAXII Community

OASIS Transition

DHS transitioned TAXII, STIX, and CybOX to Organization for the Advancement of Structured Information Standards (OASIS), a non-profit consortium that drives the development, convergence, and adoption of open standards for the global information society. The Cyber Threat Intelligence (CTI) Technical Committee (TC) now leads the ongoing development of these standards. Organizations and individuals that wish to play a regular and active role in the shaping of these standards should consider joining OASIS and the CTI TC. Learn more about the transition:

Discussion Lists & Archives

Everything that the CTI TC does is public and the discussions around the evolution of the specifications are no exception. Therefore, the CTI TC and TAXII subcommittee member-only lists are publicly archived for access by anyone at the following links:
