Secure coding is essential to protect applications from vulnerabilities. Here are key practices to follow:

1. Input Validation

Always validate user inputs to prevent injection attacks.
🚨 Use whitelists instead of blacklists for input sanitization.

2. Data Encryption

  • Encrypt sensitive data at rest and in transit 🔒
  • Use TLS 1.2 or higher for HTTPS connections
  • Implement AES-256 for data storage

3. Authentication & Authorization

  • Use OAuth 2.0 or JWT for secure access control 🛡️
  • Implement multi-factor authentication (MFA)
  • Regularly rotate API keys and credentials

4. Security Headers

Add these headers to your HTTP responses:

  • Content-Security-Policy
  • X-Content-Type-Options
  • X-Frame-Options
secure_headers

5. Dependency Management

  • Keep third-party libraries up to date 🔄
  • Use tools like OWASP Dependency-Check
  • Avoid deprecated or vulnerable packages

6. Logging & Monitoring

  • Enable detailed logging for security events 📜
  • Monitor logs for suspicious activity 🔍
  • Use SIEM tools for real-time threat detection

7. Incident Response

  • Have a clear plan for security breaches 🚨
  • Regularly test your response protocols
  • Document all security-related incidents
