Spring Security is a powerful and highly customizable framework designed to manage authentication, authorization, and other security features for Java-based applications. Whether you’re building a small application or a large-scale enterprise system, Spring Security provides a robust foundation for protecting your application from unauthorized access.
In this blog, we’ll cover the basics of Spring Security, including its architecture, key concepts, and how to implement it in a Spring Boot application.
