This skill covers designing TIP architecture using open-source tools (MISP, OpenCTI, TheHive, Cortex), configuring feed ingestion pipelines, establishing enrichment workflows, implementing STIX/TAXII interoperability, and building analyst dashboards for CTI operations.\n\n\n## When to Use\n\n- When deploying or configuring building threat intelligence platform capabilities in your environment\n- When establishing security controls aligned to compliance requirements\n- When building or improving security architecture for this domain\n- When conducting security assessments that require this implementation\n\n## Prerequisites\n\n- Docker and Docker Compose for deploying platform components\n- Python 3.9+ with `pymisp`, `pycti`, `thehive4py` libraries\n- Elasticsearch/OpenSearch cluster for data storage\n- Redis and RabbitMQ for message queuing\n- Understanding of STIX 2.1 data model and TAXII 2.1 transport\n- API keys for enrichment services (VirusTotal, Shodan, AbuseIPDB)\n\n## Key Concepts\n\n### TIP Architecture Components\n1. **Collection Layer**: Feed ingestion from OSINT, commercial, and internal sources\n2. **Storage Layer**: Elasticsearch/OpenSearch for indexed CTI data with STIX 2.1 schema\n3. **Analysis Layer**: OpenCTI for knowledge graph analysis and MISP for IOC correlation\n4. **Enrichment Layer**: Cortex analyzers for automated IOC enrichment\n5. **Response Layer**: TheHive for case management and incident response integration\n6. **Sharing Layer**: TAXII server for outbound intelligence sharing\n\n### Platform Integration Points\n- **MISP <-> OpenCTI**: Bidirectional sync via OpenCTI MISP connector\n- **OpenCTI <-> TheHive**: Alert/case creation from high-confidence indicators\n- **TheHive <-> Cortex**: Automated analysis and enrichment of case observables\n- **All <-> SIEM**: Real-time IOC push to Splunk/Elastic via API or Kafka\n\n## Workflow\n\n### Step 1: Deploy Platform with Docker Compose\n\n```yaml\nversion: '3.8'\nservices:\n  #
