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

1. Input Validation 🛡️

Always validate and sanitize user inputs to prevent injection attacks.
Use frameworks like OWASP ESAPI for robust validation.

Input Validation

2. Secure Authentication & Authorization 🔐

  • Implement strong password policies (e.g., minimum length, special characters).
  • Use multi-factor authentication (MFA) where possible.
  • Regularly audit access controls.
Secure Authentication

3. Data Encryption 🔒

Encrypt sensitive data at rest and in transit using TLS 1.2+ and AES-256.
Refer to our guide on Data Protection Techniques for deeper insights.

4. Error Handling 🚨

Avoid exposing detailed error messages to users.
Log errors securely for debugging without revealing sensitive info.

Error Handling

5. Regular Updates & Patching 🔄

Keep dependencies and libraries up to date to mitigate known vulnerabilities.
Use tools like Snyk or OWASP Dependency-Check for tracking.

6. Security Testing 🔍

Incorporate automated testing (e.g., static/dynamic analysis) into your CI/CD pipeline.
Perform penetration testing before production deployment.
