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

1. Authentication & Authorization

  • Use strong password policies 🔐 and multi-factor authentication (MFA) 🧾.
  • Implement role-based access control (RBAC) 🛡️ to limit permissions.
  • Always validate user input 🧪 to prevent injection attacks.

2. Data Protection

  • Encrypt sensitive data both at rest 🔒 and in transit 🚀 using TLS 1.3+.
  • Follow principle of least privilege 🛡️ when handling user data.
  • Use data masking 🔍 for non-essentials in logs or APIs.

3. Input Validation

  • Sanitize all user inputs 🧼 to avoid XSS or SQL injection attacks.
  • Use whitelists 📋 instead of blacklists for input validation.
  • Validate input length and format 📏 before processing.

4. Security Configuration

  • Keep software and dependencies up to date 🔄.
  • Disable unused features ⚫ in production environments.
  • Use environment-specific configurations 🌍 for secrets and credentials.
