Description
STIX 2.1 defines a set of STIX Domain Objects (SDOs). Each of these objects corresponds to a concept commonly used in cyber threat intelligence (CTI). Using the building blocks of SDOs alongside STIX relationship objects (SROs), entities can create and share broad and comprehensive CTI. This CSD provides the basis for CTI sharing and supplements the STIX 2.0 Committee Specification (CS) approved previously. The STIX 2.1 CSD01 language is provided in five parts: Part 1: STIX Core Concepts Part 2: STIX Objects Part 3: Cyber Observables Core Concepts Part 4: Cyber Observables Objects Part 5: STIX Patterning A Zip file of the 5-Part CSD01 can be found at: https://www.oasis-open.org/committees/document.php?document_id=63875&wg_abbrev=cti%20
