# Stripe Integration Security Monitoring

> Comprehensive security monitoring and audit logging for the Stripe integration.

This document outlines the comprehensive security monitoring and audit logging system implemented for the Stripe integration in Connect Tech Global.

## Overview

The security monitoring system provides real-time tracking, alerting, and forensic analysis capabilities for all Stripe-related operations, ensuring compliance with security standards and enabling rapid incident response.

## Security Event Categories

### Event Types

* **STRIPE\_SYNC\_STARTED**: Synchronization process initiated
* **STRIPE\_SYNC\_COMPLETED**: Synchronization completed successfully
* **STRIPE\_SYNC\_FAILED**: Synchronization failed with errors
* **STRIPE\_CONNECTION\_ESTABLISHED**: New Stripe account connected
* **STRIPE\_CONNECTION\_REMOVED**: Stripe account disconnected
* **STRIPE\_TOKEN\_REFRESH**: Access token refreshed
* **AUTHENTICATION\_FAILURE**: Authentication errors
* **PERMISSION\_DENIED**: Authorization failures
* **RATE\_LIMIT\_EXCEEDED**: API rate limits hit
* **MANUAL\_ALERT\_GENERATED**: Manual security alerts

### Risk Levels

* **LOW**: Normal operations, successful syncs
* **MEDIUM**: Partial failures, warnings, retryable errors
* **HIGH**: Authentication failures, permission denials
* **CRITICAL**: System-wide failures, security breaches

### Categories

* **integration**: Stripe API interactions
* **authentication**: Login and token management
* **authorization**: Permission checks
* **data\_access**: Data retrieval and modification
* **system**: Internal system events
* **compliance**: Regulatory and audit events

## Database Schema

### Security Events Table

```typescript theme={null}
securityEvents: defineTable({
  organizationId: v.optional(v.string()),
  userId: v.optional(v.string()),
  sessionId: v.optional(v.string()),
  eventType: v.string(),
  category: v.string(),
  riskLevel: v.string(),
  source: v.string(),
  ipAddress: v.optional(v.string()),
  userAgent: v.optional(v.string()),
  location: v.optional(v.string()),
  resource: v.optional(v.string()),
  resourceType: v.optional(v.string()),
  action: v.optional(v.string()),
  success: v.boolean(),
  errorCode: v.optional(v.string()),
  errorMessage: v.optional(v.string()),
  metadata: v.optional(v.any()),
  processed: v.boolean(),
  processedAt: v.optional(v.number()),
  alertGenerated: v.boolean(),
  alertLevel: v.optional(v.string()),
  timestamp: v.number(),
  createdAt: v.number(),
})
```

### Indexes

* By organization and timestamp
* By user and timestamp
* By risk level and timestamp
* By event type and category
* By processed status

## API Endpoints

### GET /api/integrations/stripe/security

Retrieve security events and monitoring data.

**Query Parameters:**

* `eventType`: Filter by event type
* `category`: Filter by category
* `riskLevel`: Filter by risk level
* `limit`: Maximum number of events (default: 50)
* `since`: Timestamp to filter events from

**Response:**

```json theme={null}
{
  "events": [...],
  "highRiskEvents": [...],
  "stats": {
    "totalEvents": 1250,
    "highRiskEvents": 15,
    "failureRate": 0.02,
    "avgResponseTime": 450
  },
  "suspiciousActivity": [...]
}
```

### POST /api/integrations/stripe/security/alert

Manage security alerts and event processing.

**Actions:**

* `mark_processed`: Mark events as processed
* `generate_alert`: Generate manual alerts

## Circuit Breaker Integration

### GET /api/integrations/stripe/circuit-breaker

Monitor circuit breaker status and health.

**Response:**

```json theme={null}
{
  "organizationStats": {...},
  "globalStats": {...},
  "overallHealth": {
    "status": "healthy",
    "openCircuits": 0,
    "totalRequests": 15420,
    "failureRate": 0.01
  }
}
```

### POST /api/integrations/stripe/circuit-breaker

Manage circuit breaker states.

**Actions:**

* `reset`: Reset circuit breaker
* `force_open`: Force circuit breaker open
* `force_close`: Force circuit breaker closed

## Security Monitoring Features

### Real-time Event Logging

All Stripe operations are automatically logged with:

* Timestamp and duration
* Organization and user context
* Success/failure status
* Error categorization
* Performance metrics
* Retry information

### Suspicious Activity Detection

Automated detection of:

* Multiple authentication failures
* Unusual API usage patterns
* Rate limit violations
* Permission escalation attempts
* Abnormal sync frequencies

### Alert Generation

Automatic alerts for:

* High-risk events
* Authentication failures
* System errors
* Performance degradation
* Security policy violations

### Compliance Reporting

* Audit trail maintenance
* Data access logging
* Change tracking
* Retention policies
* Export capabilities

## Implementation Details

### Security Event Logging

```typescript theme={null}
await logSecurityEvent(convex, {
  organizationId,
  eventType: 'STRIPE_SYNC_STARTED',
  category: 'integration',
  riskLevel: 'low',
  source: 'system',
  resource: stripeAccountId,
  action: 'sync_invoices',
  success: true,
  metadata: { syncType: 'invoices', batchSize: 100 }
});
```

### Error Categorization

Errors are automatically categorized by type:

* Rate limit errors → HIGH risk
* Authentication errors → HIGH risk
* Network errors → MEDIUM risk
* Validation errors → LOW risk

### Circuit Breaker Protection

Organization-specific circuit breakers prevent cascading failures:

* Failure threshold: 5 failures in 60 seconds
* Recovery timeout: 30 seconds
* Half-open max calls: 3
* Success threshold: 2 consecutive successes

## Best Practices

### Event Logging

1. Log all significant operations
2. Include relevant context and metadata
3. Use appropriate risk levels
4. Avoid logging sensitive data

### Monitoring

1. Set up alerts for high-risk events
2. Monitor failure rates and patterns
3. Review suspicious activity regularly
4. Maintain audit trails

### Incident Response

1. Use security events for forensic analysis
2. Correlate events across systems
3. Generate compliance reports
4. Implement automated responses

## Configuration

### Environment Variables

* `SECURITY_LOG_LEVEL`: Minimum log level (default: 'low')
* `ALERT_THRESHOLD`: Alert generation threshold
* `RETENTION_DAYS`: Event retention period (default: 90 days)

### Monitoring Intervals

* Real-time event logging
* Hourly suspicious activity detection
* Daily compliance reporting
* Weekly security reviews

## Troubleshooting

### Common Issues

1. **High event volume**: Adjust log levels and retention
2. **False positives**: Tune detection algorithms
3. **Performance impact**: Optimize database queries
4. **Alert fatigue**: Refine alert criteria

### Debugging

1. Check security event logs
2. Review circuit breaker status
3. Analyze error patterns
4. Monitor system performance

## Future Enhancements

### Planned Features

* Machine learning-based anomaly detection
* Advanced correlation analysis
* Real-time dashboard
* Mobile alerts
* Integration with SIEM systems

### Compliance Improvements

* GDPR compliance features
* SOC 2 audit support
* PCI DSS requirements
* Industry-specific regulations
