modeling-threats-with-opencti

Deploy OpenCTI (Filigran) via Docker Compose and use the pycti Python client to model threat actors, intrusion sets, campaigns, and indicators as a STIX 2.1 knowledge graph with relationships (uses, attributed-to, targets). Use when building a centralized threat-intel knowledge base, correlating IOCs from multiple feeds into one adversary graph, or producing STIX bundles for detection engineering.
