Implementation Examples

1. Logging a Compliance Event

const AuditLogger = require('../compliance/auditLogger');

// Log proof issuance with compliance metadata
await AuditLogger.logProofEvent(
  'PROOF_ISSUED',
  {
    id: 'proof-123',
    hash: 'abc123...',
    issuer: 'GABC123...',
    sensitive: true
  },
  {
    id: 'user-456',
    name: 'John Doe',
    ipAddress: '192.168.1.100',
    sessionId: 'sess-789'
  },
  {
    encryptionUsed: true,
    privacySettings: 'restricted',
    correlationId: 'corr-001'
  }
);

2. Running GDPR Compliance Check

const RegulatoryComplianceChecks = require('../compliance/regulatoryChecks');

const gdprCheck = await regulatoryChecks.runComplianceCheck('GDPR', {
  dataProcessing: true,
  consentManagement: true,
  dataRetention: true
});

console.log(`GDPR Compliance: ${gdprCheck.overallCompliance}`);
console.log(`Findings: ${gdprCheck.findings.length}`);

3. Generating Compliance Report

const ComplianceReportGenerator = require('../compliance/reportGenerator');

const report = await reportGenerator.generateComplianceReport({
  reportType: 'GDPR_COMPLIANCE',
  period: {
    startDate: '2024-01-01',
    endDate: '2024-12-31'
  },
  standards: ['GDPR'],
  scope: ['user-data-processing', 'consent-management'],
  userId: 'admin-123',
  userName: 'Compliance Admin',
  format: 'PDF'
});

4. Configuring Automated Monitoring

const AutomatedComplianceMonitoring = require('../compliance/automatedMonitoring');

// Start monitoring for access pattern violations
const monitorId = monitoring.startMonitoring({
  monitorId: 'access-violation-monitor',
  type: 'ACCESS_PATTERNS',
  interval: 300000, // 5 minutes
  rules: {
    threshold: 10,
    failedThreshold: 5,
    timeWindow: 3600000 // 1 hour
  },
  severity: 'HIGH'
});

5. Frontend Integration

// Audit Trail Component
import AuditTrail from '../components/Compliance/AuditTrail';

function CompliancePage() {
  return (
    <div className="space-y-6">
      <AuditTrail resourceId="proof-123" />
      <ComplianceReports />
      <ComplianceDashboard />
    </div>
  );
}
