#STIX Version 1.2.1 by the OASIS Cyber Threat Intelligence (#CTI) TC is now available

OASIS is pleased to announce the availability of a new Committee Specification from the members of the Cyber Threat Intelligence (CTI) TC:

STIX Version 1.2.1
Committee Specification 01
05 May 2016

What is STIX and why is it important?

The Structured Threat Information Expression (STIX) is the result of a collaborative, community-driven effort to define and develop a framework for expressing cyber threat information in a way that enables cyber threat information sharing and cyber threat analysis. The STIX framework comprises a collection of extensible component specifications along with an overarching core specification and supporting specifications. STIX Version 1.2.1 provides an overview of those specifications and defines how they are used within the broader STIX framework.

About the TC:

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

The TC has transitioned STIX (Structured Threat Information Expression), TAXII (Trusted Automated Exchange of Indicator Information), and CybOX (Cyber Observable Expression) from the US Department of Homeland Security (DHS) for standardization under the OASIS open standards process. STIX Version 1.2.1 is the first of these to be released as an OASIS Committee Specification.

Members of the TC are currently working on the next generation of these specifications.

STIX, TAXII, and CybOX recently received the European Identity Conference (EIC) 2016 Award for Best Innovation/New Standard in Information Security.
