A banking application handles highly sensitive information such as account details, transaction records, passwords and personal data. Therefore, strong authentication and authorization are essential to prevent unauthorized access and financial fraud. Spring Security provides a comprehensive framework for implementing these security requirements in web applications. Authentication is the process of verifying the identity of a user. Spring Security supports several authentication mechanisms, including username-password authentication, form-based login, HTTP Basic authentication, OAuth2, OpenID Connect and integration with LDAP or other identity providers. For a banking application, multi-factor authentication can be added so that users provide a password along with an OTP, authenticator code or biometric verification. This provides stronger protection than passwords alone. Authorization determines what an authenticated user is permitted to do. Spring Security supports role-based and authority-based access control. For example, a normal customer may be allowed to view account balances and transfer money, while an administrator may have access to account-management functions. Method-level security using annotations such as `@PreAuthorize` can protect sensitive business
