This guide covers advanced security techniques to protect your applications and data. Whether you're securing APIs, managing user authentication, or implementing encryption, these strategies will help you build a robust defense system.

Key Concepts 🔒

  • Authentication & Authorization: Use OAuth 2.0 or JWT for secure user access control.
  • Data Encryption: Always encrypt sensitive data at rest and in transit (e.g., TLS 1.3).
  • Input Validation: Prevent injection attacks by sanitizing all user inputs.
  • Rate Limiting: Mitigate DDoS attacks with middleware like NGINX or Cloudflare.

Best Practices 🛡️

  1. Regular Audits: Conduct penetration testing and vulnerability assessments.
  2. Least Privilege Principle: Restrict permissions to the minimum required for tasks.
  3. Secure Headers: Implement Content-Security-Policy and X-Content-Type-Options.
  4. Logging & Monitoring: Use tools like ELK Stack for real-time threat detection.

Tools & Techniques 🛠️

  • SSL/TLS: Configure secure connections for HTTPS.
  • Firewalls: Use iptables or cloud-based WAFs (Web Application Firewalls).
  • Two-Factor Authentication (2FA): Add an extra layer of security for user logins.
