Spring Security

Spring Security is a powerful and highly customizable authentication and access-control framework within the Spring ecosystem, providing a comprehensive solution for securing Java-based enterprise applications. It offers declarative security for handling authentication (verifying a user's identity) and authorization (enforcing access policies), integrating seamlessly with various mechanisms like form-based login, LDAP, and OAuth 2.0. Furthermore, it provides robust protection against common web vulnerabilities such as Cross-Site Request Forgery (CSRF), session fixation, and clickjacking, making it the de facto standard for implementing security within the Spring Framework.
