Securing API endpoints against unauthorized access is crucial for protecting sensitive data and maintaining system integrity. Implementing robust authentication and authorization mechanisms, along with encryption and monitoring, are key strategies in this process.

Example Concept: To secure API endpoints, use OAuth 2.0 for authentication, ensuring that only authorized clients can access the API. Implement rate limiting to prevent abuse and DDoS attacks, and use HTTPS to encrypt data in transit. Additionally, regularly audit and log API access to detect and respond to unauthorized attempts promptly.

Additional Comment:

Use API gateways to manage and secure traffic effectively.
Implement IP whitelisting to restrict access to known and trusted sources.
Regularly update and patch API components to mitigate vulnerabilities.
Employ input validation to prevent injection attacks.
