TAXII overview

TAXII standardizes the exchange of cyber threat intelligence (CTI) over the internet, enabling organizations to share security threat information more efficiently and effectively. This improves threat detection, analysis, and response.

Trusted Automated Exchange of Indicator Information (TAXII) is a protocol used for the exchange of cyber threat intelligence (CTI) over the internet. TAXII is designed to support the distribution of CTI using a standardized methodology, enabling organizations to share information about security threats more efficiently and effectively.

TAXII is often used in conjunction with Structured Threat Information Expression (STIX), which is a language and serialization format used to exchange CTI. STIX enables organizations to convey the full range of potential threat information, from high-level attack patterns and technical indicators to detailed threat actor profiles and the tactics, techniques, and procedures (TTPs) that they use.

Together, TAXII and STIX facilitate the automated exchange, processing, and analysis of cyber threat information among various parties, including private sector organizations, government agencies, and other entities involved in cybersecurity defense. This leverages shared knowledge about existing and emerging threats to help improve the speed and accuracy of threat detection, analysis, and response.
