1. What is the purpose of CSRF protection in Spring Boot Security?
   • CSRF (Cross-Site Request Forgery) protection in Spring Boot Security safeguards against malicious attacks by generating and validating unique tokens for each user session, ensuring that requests originate from trusted sources.
2. How can you implement role-based access control (RBAC) in Spring Boot Security?
   • Role-based access control can be implemented in Spring Boot Security by assigning specific roles to users and configuring security rules to allow or restrict access based on those roles.
3. What is the difference between stateful and stateless authentication in Spring Boot Security?
   • Stateful authentication in Spring Boot Security involves storing user session information on the server, while stateless authentication relies on self-contained tokens (such as JWT) for authentication, eliminating the need for server-side session storage.
4. How can you customize the login form in Spring Boot Security?
   • The login form in Spring Boot Security can be customised by creating a custom login page and configuring the appropriate URL mapping and security settings in the security configuration.

   • The @CrossOrigin annotation is used to enable Cross-Origin Resource Sharing (CORS) in Spring Boot Security, allowing controlled access to resources from different origins or domains.
6. How can you handle authentication failure in Spring Boot Security?
   • Authentication failure in Spring Boot Security can be handled by implementing the AuthenticationFailureHandler interface and configuring it to perform specific actions, such as redirecting to a custom error page or returning an error message.
7. What is the purpose of the Remember Me feature in Spring Boot Security?
   • The Remember Me feature in Spring Boot Security allows users to remain authenticated even after their session expires.
   • It is achieved by storing a persistent token in a cookie or database to automatically log users back in.
8. How can you integrate Spring Boot Security with a database for user authentication?
   • Spring Boot Security can be integrated with a database for user authentication by implementing the UserDetailsService interface and configuring it to load user details from the database during the authentication process.
9. What is the purpose of the @PostAuthorize annotation in Spring Boot Security?
   • The @PostAuthorize annotation is used for method-level security to specify a post-authorization expression that is evaluated after the method is executed.
   • It can be used to further restrict access to method results based on certain conditions.
10. How can you handle access denied situations in Spring Boot Security?
    • Access denied situations in Spring Boot Security can be handled by implementing the AccessDeniedHandler interface and configuring it to perform actions such as redirecting to an error page or returning a customised error message.
