OASIS members and other interested parties,
The OASIS Cyber Threat Intelligence (CTI) TC [1] members have recently approved a Committee Specification Draft (CSD) and submitted it for 30-day public review:
STIX™ Version 2.0
Committee Specification Draft 01 / Public Review Draft 01
24 February 2017
What is STIX and why is it important?
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.
About the TC:
