Subject: Invitation to comment on STIX™ v2.0 - ends June 1st


OASIS members and other interested parties, 

We are pleased to announce that STIX™ Version 2.0 from the OASIS Cyber Threat Intelligence (CTI) TC is now available for public review and comment. This release has been updated based on feedback from the first public review. The comments received in that review and their resolution can be found at http://docs.oasis-open.org/cti/stix/v2.0/csprd01/stix-v2.0-csprd01-comment-resolution-log.xlsx

Structured Threat Information _expression_ (STIX) is a language and serialization format used to exchange cyber threat intelligence (CTI). STIX enables organizations to share CTI with one another in a consistent and machine readable manner, allowing security communities to better understand what computer-based attacks they are most likely to see and to anticipate and/or respond to those attacks faster and more effectively. STIX is designed to improve many different capabilities, such as collaborative threat analysis, automated threat exchange, automated detection and response, and more.

In response to lessons learned in implementing previous versions, STIX has been significantly redesigned and, as a result, omits some of the objects and properties defined in STIX 1.2.1 (see STIX Version 1.2.1 Part 1: Overview at http://docs.oasis-open.org/cti/stix/v1.2.1/stix-v1.2.1-part1-overview.html). The objects chosen for inclusion in STIX 2.0 represent a minimally viable product (MVP) that fulfills basic consumer and producer requirements for CTI sharing. Objects and properties not included in STIX 2.0, but deemed necessary by the community, will be included in future releases.

STIX v2.0 is developed by the OASIS Cyber Threat Intelligence (CTI) TC. The CTI TC is developing information representations and protocols to help industries, organizations, and governments model, analyze, and share cyber threat intelligence.

STIX is published in five parts. The documents and related files are available here:
