Secure Messaging Infrastructure

The Secure Messaging Infrastructure provides reliable communication channels for GDPR compliance alerts, notifications, and event handling. This system ensures that important compliance events are reliably delivered and processed.

Architecture Overview

Core Components for GDPR Compliance

Secure Message Distribution

The secure message distribution system ensures reliable delivery of compliance-critical information:

Component	Function	GDPR Relevance
DPO Alert Service	Delivers time-sensitive notifications	Required for 72-hour breach notification
GDPR Report Distribution	Distributes compliance reports	Supports Article 30 documentation
Security Alert System	Delivers security notifications	Supports Article 32 security measures
Compliance Command System	Processes compliance actions	Enables timely remediation activities

Configuration for Data Protection

Security Settings

The system is configured with the following security features to support GDPR compliance:

• End-to-End Encryption: All messages are encrypted in transit and at rest
• Access Controls: Role-based permissions for message processing
• Audit Logging: Complete logs of all message events
• Geographical Constraints: EU-based message processing
• Retention Controls: Automatic message expiration according to policy

Notification Types for DPOs

1. DPO Alert Notifications

Urgent notifications for Data Protection Officers:

Notification Type	Purpose	Example
Data Breach Alert	Notifies of potential breach	"Unusual access pattern detected in customer database"
Regulatory Update	Informs of new requirements	"New EDPB guidance published on consent mechanisms"
Processing Risk	Highlights risk increase	"Processing volume exceeds threshold in German operations"

2. GDPR Compliance Reports

Automated distribution of compliance documentation:

Report Type	Content	Frequency
Processing Activity Summary	Changes to Article 30 records	Weekly
Data Subject Request Log	Record of rights exercises	Monthly
Cross-border Transfer Audit	Analysis of international transfers	Quarterly
Processor Compliance	Summary of processor compliance status	Monthly

3. Security Notifications

Alerts related to security measures required by Article 32:

Alert Type	Purpose	Priority
Access Control Events	Unauthorized access attempts	High
Encryption Status	Issues with encryption implementation	High
Backup Verification	Results of backup restoration tests	Medium
Vulnerability Scan	New vulnerabilities affecting systems	Variable

Implementation for DPOs

Compliance Workflow Integration

For Data Protection Officers, the messaging system integrates with key compliance workflows:

1. Breach Management: Automated notification workflow for potential data breaches
2. Documentation Updates: Triggered updates to compliance documentation
3. Supervisory Authority Communication: Prepared communications for authorities
4. Data Subject Request Handling: Coordinated processing of rights exercises

Customizing Notifications

DPOs can configure the notification system to match their specific needs:

• Priority Levels: Set different urgency levels for different notification types
• Delivery Channels: Configure email, SMS, in-app, or other notification methods
• Escalation Rules: Define automatic escalation for unacknowledged high-priority alerts
• Working Hours: Set different notification rules during and outside working hours
• Geographic Routing: Direct notifications to appropriate regional DPOs

Benefits for European DPOs

• Demonstrable Compliance: Comprehensive logs support accountability requirements
• Timely Awareness: Immediate notification of compliance issues
• Consistent Communication: Standardized formats for compliance communication
• Reliable Delivery: Guaranteed message delivery even during system disruptions
• Cross-Border Coordination: Coordinated notifications across multiple EU jurisdictions

GDPR Article Support

This system specifically supports the following GDPR articles:

• Article 33-34: Data breach notification requirements
• Article 30: Records of processing activities
• Article 32: Security of processing
• Articles 37-39: DPO responsibilities
• Article 5(2): Accountability principle }

// Send GDPR scan report command await serviceBus.gdprScanCommandGenerateReport({ scanId: 'scan_123', organizationId: 'org_456', });

### 3. Security Scan Reports

```typescript
interface ISecurityScanEventIssuesScanFinishedParams {
  scanId: string;
  issues: any[];
  // other parameters
}

// Send security scan completion event
await serviceBus.securityScanEventIssuesScanFinished({
  scanId: 'scan_789',
  issues: [],
});

Usage Examples

Initialize Service Bus

@Injectable()
class YourService {
  constructor(private serviceBus: ServiceBusService) {}

  async initialize() {
    // Service bus automatically initializes on construction
    // Senders and receivers are ready to use
  }
}

Send Messages

// Send WebSocket command
await serviceBus.websocketCommandEmit({
  to: `organization:${orgId}`,
  event: 'notification',
  payload: {
    type: 'update',
    message: 'Process completed',
  },
});

// Send GDPR scan report command
await serviceBus.gdprScanCommandGenerateReport({
  scanId,
  organizationId,
  timestamp: new Date(),
});

Receive Messages

// Setup message receiver
const receiver = serviceBus.daisyCommandCreateChargeReceiver;

// Subscribe to messages
receiver.subscribe({
  processMessage: async (message) => {
    try {
      await processChargeCommand(message.body);
      await message.complete();
    } catch (error) {
      await message.abandon();
    }
  },
  processError: async (error) => {
    logger.error('Error processing message', error);
  },
});

Best Practices

1. Message Handling

• Implement idempotent message processing
• Handle message completion properly
• Implement dead-letter handling
• Monitor message processing times

2. Error Handling

try {
  await serviceBus.websocketCommandEmit(params);
} catch (error) {
  logger.error('Failed to send message', {
    queue: 'websocket',
    params,
    error: error.message,
  });
  // Implement retry logic or fallback
}

3. Resource Management

• Monitor queue sizes
• Implement message TTL
• Handle backpressure
• Clean up resources

Performance Optimization

1. Message Batching

// Send multiple messages in batch
await sender.sendMessages([
  { body: message1 },
  { body: message2 },
  { body: message3 },
]);

2. Concurrent Processing

// Configure concurrent message processing
const receiver = client.createReceiver(queueName, {
  receiveMode: 'peekLock',
  maxConcurrentCalls: 5,
});

3. Message Sessions

// Use sessions for ordered processing
const sessionReceiver = client.createReceiver(queueName, {
  receiveMode: 'peekLock',
  sessionId: 'session1',
});
