Security Best Practices

1. API Key Management

   • Store API keys in environment variables.
   • Rotate keys regularly.
   • Use different keys for each environment.

2. Access Control

   • Implement rate limiting.
   • Configure IP whitelisting.
   • Apply the principle of least privilege.

3. Monitoring

   • Enable audit logging.
   • Monitor authentication failures.
   • Set up alerts for suspicious activities.

⚠️ Important Note

Ensure that all API keys are properly secured to avoid leakage.

💡 Usage Tip

Conduct regular security audits to prevent potential vulnerabilities and enable appropriate error handling mechanisms in the production environment.
