What is CSRF protection in Laravel, and how is it implemented?
Answer: CSRF (Cross-Site Request Forgery) protection in Laravel is a security feature that prevents unauthorized commands from being transmitted from a user that a web application trusts. It helps protect against attackers trying to perform actions on behalf of a user without their consent.
In Laravel, CSRF protection is implemented automatically by generating a CSRF token for each active user session. This token is included in all forms submitted via POST requests. Laravel provides a helper function, `csrf_field()`, to include the CSRF token in forms, or you can use the `@csrf` Blade directive.
When a form is submitted, Laravel checks that the submitted token matches the token stored in the user’s session. If the tokens do not match, a `TokenMismatchException` is thrown, preventing the action from being executed.
