Spring Security

Spring Security is a framework that helps protect web applications built with the Spring framework. It provides essential security features like user authentication (verifying who you are) and authorization (determining what you can do). Think of it as a security guard for your website, ensuring that only the right people can access certain parts of the site and that sensitive data is kept safe. It can integrate with various authentication methods, including usernames and passwords, social logins, and more. By using Spring Security, developers can build robust, secure applications more easily.
