How can Spring Boot's built-in features help prevent DDoS attacks?

While Spring Boot itself doesn't have explicit DDoS prevention features, you can leverage rate limiting using Spring's AOP and filters. Implement custom filters to track request frequency from each IP address and block those exceeding a defined threshold. Integrate with caching mechanisms (like Redis) to efficiently store and retrieve request counts. Also, proper request validation and input sanitization will prevent malformed requests from overwhelming the application.
