Have you only used Spring Security features to ensure security?

Spring Security provides a powerful set of tools for securing Java applications, including authentication, authorization, CSRF protection, session management, and more. However, in real projects, additional security measures are often applied, such as:

• Using HTTPS and configuring SSL/TLS at the server level.
• Validating and sanitizing input data to prevent XSS and SQL injection.
• Integrating with external authentication systems (OAuth2, LDAP).
• Monitoring and security auditing.

Thus, Spring Security is often used as a foundation, but other approaches and tools are also employed for comprehensive security.
