Python-based enrichment pipeline:
# Workflow:
Suricata Alert → Extract IPs → Query AlienVault OTX
→ Query AbuseIPDB → Calculate Threat Score
→ Assign Verdict → Generate ReportFeatures:
- ✅ Extracts IPs from Suricata alerts
- ✅ Queries AlienVault OTX for threat pulses
- ✅ Checks AbuseIPDB for reputation scores
- ✅ Calculates composite threat score (0-100)
- ✅ Assigns verdict (CRITICAL/HIGH/MEDIUM/LOW)
- ✅ Generates JSON report with full context
- ✅ Indexes enriched data to Elasticsearch
Sample Output:
{
"ip": "194.180.48.63",
"threat_score": 50,
"verdict": "HIGH",
"abuseipdb": {
"confidence_score": 100,
"total_reports": 14659,
"country": "PL",
"isp": "Neterra Ltd."
},
"alert_count": 11

-
Layered Defense - Multiple detection mechanisms (signatures + custom rules + threat intel) provided comprehensive coverage and caught threats that single-layer defenses might miss
-
Automation - Python scripts reduced manual threat enrichment time by 90%, allowing focus on analysis rather than data gathering
-
Open Source - Leveraged free/open-source tools (Suricata, ELK, OTX, AbuseIPDB) to build enterprise-grade capabilities without licensing costs
-
Documentation - Thorough documentation enabled knowledge transfer and made the project reproducible for portfolio and learning purposes
