Building Threat Intelligence Feed Integration

When to Use

Use this skill when:

• SOC teams need automated ingestion of threat intelligence feeds into SIEM platforms
• Multiple TI sources require normalization into a common format (STIX 2.1)
• Detection systems need real-time IOC matching against network and endpoint telemetry
• TI feed quality assessment and deduplication processes need to be established

Do not use for manual IOC lookup — use dedicated enrichment tools (VirusTotal, AbuseIPDB) for ad-hoc queries.

Prerequisites

• MISP instance or Threat Intelligence Platform (TIP) for feed aggregation
• STIX/TAXII client library (taxii2-client, stix2 Python packages)
• SIEM platform (Splunk ES, Elastic Security, or Sentinel) with TI framework configured
• API keys for commercial and open-source feeds (AlienVault OTX, Abuse.ch, CISA AIS)
• Python 3.8+ for feed processing automation
