Spring Security is the Spring Framework's application security solution. Spring Security can be used to secure URLs and method invocations. It is widely used to secure standalone web applications and REST APIs.
Spring Security is a powerful and highly customizable authentication and access-control framework. It also provides defense against several common web application attacks. It is the de-facto standard for securing spring-based applications.
Spring Security is one of the most mature and widely used Spring projects. It was founded in 2003 and has been actively maintained by the Spring Team since. Today it is used to secure numerous demanding environments including government agencies, military applications, and central banks. It is released under an Apache 2.0 license so you can confidently use it in your projects.
Spring Security is also easy to learn, deploy and manage. Its dedicated security namespace provides directives for most common operations, allowing complete application security in just a few lines of Java or XML.
Spring Security is also integrated with many other Spring technologies, including Spring MVC, Spring WebFlux, and Spring Messaging.
