What is Spring secruity?

Spring Security is a powerful and widely-used framework in the Java ecosystem, designed to handle security concerns in Spring-based applications. It provides comprehensive authentication, authorization, and access control features to safeguard web applications and RESTful services.

With Spring Security, developers can easily integrate various authentication mechanisms, such as username/password, OAuth, and more. It also enables the management of roles and permissions to control user access to different parts of the application. Spring Security plays a crucial role in ensuring the confidentiality, integrity, and availability of resources within a Spring application.

The older versions of sprint security 5 are deprecated, the new versions from 5 are re written to add more security and perform better. old versions are 2.4.x and 2.5.x, but new version is named as 0.0.1 which normally confuses people.
