Secure Integration Patterns

Secure Integration Patterns are essential for ensuring that different components of a software system can communicate securely. This lesson covers various integration patterns and their implications on security.

• Authentication - Verifying the identity of a user or system.
• Authorization - Determining what an authenticated user or system is allowed to do.
• Encryption - Protecting data by converting it into an unreadable format for unauthorized users.
• Secure Communication - Ensuring that the data in transit is protected against eavesdropping and tampering.

1. API Gateway Pattern

The API Gateway is a single entry point for all client requests. It facilitates the management of user authentication, routing, and data aggregation.

2. Service Mesh Pattern

A service mesh provides a dedicated infrastructure layer for managing service-to-service communication. It handles load balancing, service discovery, and encryption of data in transit.

3. Event-Driven Architecture

In this pattern, services communicate by producing and consuming events, which enhances decoupling and scalability.

const eventEmitter = require('events');
const myEmitter = new eventEmitter();

myEmitter.on('event', () => {
  console.log('An event occurred!');
});

myEmitter.emit('event');

1. Always validate and sanitize inputs to prevent injection attacks.
2. Use HTTPS for all communication to encrypt data in transit.
3. Implement token-based authentication (e.g., JWT) for APIs.
4. Monitor and log all access to services for auditing purposes.
5. Regularly update and patch dependencies to mitigate vulnerabilities.
