What are effective methods for securing API endpoints?
Asked on Feb 19, 2026
Answer
Securing API endpoints is crucial to protect sensitive data and maintain system integrity. Effective methods include implementing authentication, authorization, encryption, and monitoring strategies to ensure that only legitimate requests are processed and data is protected in transit.
Example Concept: To secure API endpoints, use OAuth 2.0 for authentication to ensure that only authorized users can access the API. Implement rate limiting to prevent abuse and DDoS attacks. Encrypt data in transit using TLS to protect against eavesdropping. Regularly audit API logs to detect and respond to suspicious activities promptly. Additionally, apply input validation and sanitization to prevent injection attacks.
Additional Comment:
- Consider using API gateways to centralize security controls and manage traffic.
- Ensure that API keys and secrets are stored securely and rotated regularly.
- Implement CORS policies to control which domains can interact with your API.
- Regularly update and patch API software to mitigate vulnerabilities.
