OASIS Transition

DHS transitioned CybOX, STIX, and TAXII 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 CybOX subcommittee member-only lists are publicly archived for access by anyone at the following links:

Non-OASIS members can sign up for the public cti-users mailing list:

CTI Users List

A new mailing list,, has been created that is intended for discussing topics related to the effective use of STIX/TAXII/CybOX and the development of solutions that use these standards. Unlike the other CTI TC lists, this list will be open to anyone to join and post to.

If you are interested in joining the cti-users list you will need to explicitly subscribe. You may do that by sending a blank email message to and then replying to the list server's email response requesting confirmation.
