Implementing STIX/TAXII Feed Integration

Overview

STIX (Structured Threat Information eXpression) and TAXII (Trusted Automated eXchange of Intelligence Information) are OASIS open standards for representing and transporting cyber threat intelligence. This skill covers implementing a STIX/TAXII 2.1 feed consumer and producer using Python, configuring TAXII server discovery, collection management, polling for new intelligence, parsing STIX 2.1 objects, and integrating feeds into SIEM and TIP platforms.

Prerequisites

• Python 3.9+ with taxii2-client, stix2, cti-taxii-client libraries
• Understanding of STIX 2.1 data model (SDOs, SCOs, SROs)
• Understanding of TAXII 2.1 protocol (discovery, API roots, collections)
• Network access to TAXII servers (MITRE ATT&CK TAXII, Anomali STAXX)
• Optional: medallion for running a local TAXII 2.1 server
