Previous Question Next Question

To secure API endpoints from unauthorized access, you should implement authentication, encryption, and proper access controls. These measures ensure that only authorized users can interact with your API securely.

Example Concept: Use OAuth 2.0 for API authentication, which involves issuing tokens to clients after they authenticate. The client then includes this token in the Authorization header of each request. This ensures that only requests with valid tokens can access the API endpoints.

Additional Comment:

Always use HTTPS to encrypt data in transit, protecting it from eavesdropping.
Implement rate limiting to prevent abuse and potential denial-of-service attacks.
Regularly review and update access controls to ensure they align with the principle of least privilege.
