What is CSRF and how does it affect Angular applications?

CSRF stands for Cross-Site Request Forgery. It's an attack that tricks the user into executing unwanted actions on a web application where they're authenticated. In Angular applications, CSRF can be a concern if proper security measures aren't implemented.

How can I protect my Angular app from CSRF attacks?

To protect your Angular app from CSRF attacks, you can implement anti-CSRF tokens, use the SameSite cookie attribute, and ensure that your backend validates requests properly.

Can you explain how anti-CSRF tokens work?

Anti-CSRF tokens are unique, secret tokens generated by the server and sent to the client. The client must include this token in subsequent requests, allowing the server to verify that the request is legitimate.

Are there any libraries that can help with CSRF protection in Angular?

Yes, libraries like Angular's built-in HttpClient can help manage CSRF tokens automatically. Additionally, you can use third-party libraries like ngx-csrf to simplify the implementation.
