What are effective methods to secure API endpoints against unauthorized access?
Asked on Jan 07, 2026
Answer
To secure API endpoints against unauthorized access, implement authentication, authorization, and encryption mechanisms. Use HTTPS to encrypt data in transit and apply security headers to protect against common vulnerabilities.
Example Concept: API security involves multiple layers, including authentication (verifying the identity of users), authorization (ensuring users have permission to access resources), and encryption (protecting data in transit). Security headers like "Content-Security-Policy", "X-Content-Type-Options", and "Strict-Transport-Security" can further enhance protection by mitigating risks such as cross-site scripting and data sniffing.
Additional Comment:
- Use OAuth 2.0 or JWT for robust authentication and authorization.
- Implement rate limiting to prevent abuse and DDoS attacks.
- Regularly update and patch API dependencies to fix vulnerabilities.
