API Security: Best Practices and Tutorials

🔒 Protecting your API is critical to ensure data integrity, privacy, and system reliability. Here’s a guide to mastering API security concepts:

Key Security Measures

1. Authentication & Authorization

   • Use OAuth 2.0 or JWT to validate user identities.
   • Implement role-based access control (RBAC) to restrict permissions.
   • 📌 Learn more about authentication

2. Data Encryption

   • Always enable SSL_TLS for secure data transmission.
   • Encrypt sensitive data at rest using AES-256 or similar standards.
   • 🔐 Explore encryption techniques

3. Rate Limiting & Throttling

   • Prevent abuse by limiting request frequency.
   • Use tools like NGINX or Redis for efficient rate control.
   • ⚙️ Configure rate limits

4. Input Validation

   • Sanitize user inputs to avoid injection attacks.
   • Validate data types and formats before processing.
   • 🧠 Best practices for input validation

5. API Gateway Usage

   • Centralize security rules via an API gateway (e.g., AWS API Gateway, Kong).
   • Monitor and log all API activity for anomaly detection.
