What are best practices to secure an API from unauthorized access?
Asked on Dec 15, 2025
Answer
To secure an API from unauthorized access, implement authentication, use HTTPS, and apply protective headers. These measures help ensure that only authorized users can access your API while maintaining data integrity and confidentiality.
Example Concept: API security involves using authentication methods like OAuth 2.0 or API keys to verify user identity. Implementing HTTPS encrypts data in transit, preventing interception. Protective headers such as "Content-Security-Policy", "X-Content-Type-Options", and "Strict-Transport-Security" further enhance security by mitigating common web vulnerabilities.
Additional Comment:
- Always use HTTPS to encrypt data between the client and server.
- Implement rate limiting to prevent abuse and DDoS attacks.
- Regularly update and patch your API to protect against known vulnerabilities.
