What are STIX/TAXII standards?

STIX (Structured Threat Information Expression) is a standardized format for representing threat intelligence: indicators, attack patterns, threat actors, and relationships. Machine-readable structure enables automated processing.

TAXII (Trusted Automated Exchange of Indicator Information) defines how to share STIX data: transport protocols, sharing models, and access controls. Together, they enable interoperable threat intelligence exchange.

Adoption: major security platforms support STIX/TAXII, enabling sharing across vendor boundaries. Standards facilitate intelligence sharing that would be difficult with proprietary formats.
