CRA Incident Reporting to ENISA Guide

Building Automated ENISA Reporting

The CRA requires reporting actively exploited vulnerabilities to ENISA within 24 hours. Manual processes won’t scale. Here’s how to automate it.

The Reporting Workflow

Vulnerability Detected

Is it actively exploited? ──No──→ Standard vulnerability handling
  ↓ Yes

Technical Implementation

Monitoring for Exploited Vulnerabilities

import asyncio
from datetime import datetime, timedelta

class ExploitMonitor:
    SOURCES = [
        "https://www.cisa.gov/known-exploited-vulnerabilities-catalog",
        "https://api.vulncheck.com/v3/index/initial-access",
    ]
    
    async def check_for_exploits(self):
        for source in self.SOURCES:
            new_exploits = await self.fetch_updates(source)
            
            for exploit in new_exploits:
                # Check if our products are affected
                affected = await self.check_affected_products(exploit.cve_id)
                
                if affected:
                    await self.trigger_reporting_workflow(exploit, affected)
    
    async def trigger_reporting_workflow(self, exploit, affected_products):
        incident = CRAIncident(
            cve_id=exploit.cve_id,
            severity=exploit.cvss_score,
            affected_products=affected_products,
            deadline=datetime.utcnow() + timedelta(hours=24),
            status="early_warning_pending",
        )
        
        # Alert security team immediately
        await self.alert_security_team(incident)
        
        # Start automated reporting
        await self.enisa_reporter.submit_early_warning(incident)

ENISA Report Generator

class ENISAReportGenerator:
    def generate_early_warning(self, incident):
        return {
            "report_type": "early_warning",
            "timestamp": datetime.utcnow().isoformat(),
            "manufacturer": {
                "name": "Your Company",
                "eu_contact": "security@company.eu",
            },
            "vulnerability": {
                "cve_id": incident.cve_id,
                "severity": incident.severity,
                "actively_exploited": True,
                "exploitation_details": incident.exploit_description,
            },
            "affected_products": [
                {
                    "name": p.name,
                    "versions": p.affected_versions,
                    "estimated_users": p.user_count,
                    "regions": p.deployment_regions,
                }
                for p in incident.affected_products
            ],
            "initial_mitigation": incident.temporary_mitigation,
            "expected_patch_date": incident.estimated_patch_date,
        }

Deadline Tracking Dashboard

# Prometheus alerting for reporting deadlines
groups:
- name: cra-reporting
  rules:
  - alert: CRAReportingDeadlineApproaching
    expr: (cra_incident_deadline_timestamp - time()) < 7200  # 2 hours remaining
    labels:
      severity: critical
    annotations:
      summary: "CRA ENISA report due in {{ $value | humanizeDuration }}"
      
  - alert: CRAReportingDeadlineMissed
    expr: (cra_incident_deadline_timestamp - time()) < 0
    labels:
      severity: page
    annotations:
      summary: "CRA ENISA reporting deadline MISSED for incident {{ $labels.cve_id }}"

Key Requirements

1. 24/7 monitoring — vulnerabilities don’t wait for business hours
2. Automated SBOM scanning — know immediately when a CVE affects your products
3. Pre-written templates — don’t draft reports under time pressure
4. Clear escalation paths — who approves ENISA submissions?
5. Drill regularly — practice the 24-hour workflow quarterly
