Previous Question Next Question

To secure API endpoints against unauthorized access, implement authentication, encryption, and protective headers to ensure only authorized users can access your resources.

Example Concept: Securing API endpoints involves using authentication mechanisms like OAuth 2.0 or API keys, ensuring data is encrypted with HTTPS, and applying protective headers such as "Content-Security-Policy" and "Strict-Transport-Security" to prevent unauthorized access and data interception.

Additional Comment:

Always use HTTPS to encrypt data in transit, preventing eavesdropping and man-in-the-middle attacks.
Implement rate limiting to protect against brute force attacks and abuse.
Regularly rotate API keys and tokens to minimize the risk of compromised credentials.
