Correlate IOC Skill
Check for existing SIEM alerts and cases related to specific Indicators of Compromise.
Inputs
IOC_LIST- Single IOC or list of IOCs (e.g.,["198.51.100.10", "evil-domain.com"])- (Optional)
TIME_FRAME_HOURS- Lookback period for SIEM alerts (default: 168 = 7 days) - (Optional)
SOAR_CASE_FILTER- Additional filter for SOAR cases (e.g.,status="OPEN")
Workflow
Step 1: Correlate SIEM Alerts
Search for alerts containing any IOC in the list:
secops-mcp.get_security_alerts(
query=IOC_based_query,
hours_back=TIME_FRAME_HOURS
)Store summary in RELATED_SIEM_ALERTS:
- Alert count
- Alert types/names
- Severity distribution
- Affected assets
Step 2: Correlate Cases
Search for cases containing any IOC:
secops-soar.list_cases(
filter=IOC_based_filter + SOAR_CASE_FILTER
)Store summary in RELATED_SOAR_CASES:
- Case IDs and names
- Case status
- Case priority
Required Outputs
After completing this skill, you MUST report these outputs:
| Output | Description |
|---|---|
RELATED_SIEM_ALERTS | Summary of SIEM alerts related to the IOC(s) |
RELATED_CASES | Summary of cases related to the IOC(s) |
CORRELATION_STATUS | Success/failure status of the correlation |
MALICIOUS_CONFIDENCE | Derived confidence based on alert history: high, medium, low, or none |
Use Cases
- Before Investigation - Check if IOC is already under investigation
- During Enrichment - Understand internal activity for an IOC
- Threat Hunt - Find all alerts/cases related to campaign indicators
- Incident Response - Identify scope of compromise across cases
