What is CORS and how does it affect API security?

CORS stands for Cross-Origin Resource Sharing. It's a security feature implemented in web browsers that allows or restricts web applications from making requests to a domain different from the one that served the web page.

Why is CORS important for APIs?

CORS is crucial for APIs because it helps prevent malicious websites from accessing sensitive data from another domain without permission, thus protecting user data.

How can I enable CORS in my API?

You can enable CORS in your API by setting the appropriate headers in your server response, such as 'Access-Control-Allow-Origin' to specify which domains are allowed to access your resources.

Are there any security risks associated with CORS?

Yes, if not configured properly, CORS can expose your API to security risks, such as allowing unauthorized domains to access sensitive data.
