Leveraging STIX and TAXII for better Cyber Threat Intelligence (Part 1)

This article introduces STIX (a structured, JSON-based language for representing CTI) and TAXII (an HTTPS application protocol for exchanging CTI), outlining how they enable standardized, automatable sharing of threat information. It highlights STIX use cases (analyzing threats, defining indicator patterns, managing response), explains TAXII services (Collections and reserved Channels), and summarizes sharing models (hub-and-spoke, source/subscriber, peer-to-peer), with references for further reading.
