Java EE Security is a framework that provides a set of APIs and services to secure enterprise applications built on the Java EE platform. It helps developers implement authentication, authorization, and secure communication, ensuring that only authorized users can access specific resources and data. The framework supports various security mechanisms, including role-based access control and integration with identity management systems. By using Java EE Security, developers can focus on building their applications while relying on established security practices to protect sensitive information and maintain compliance with industry standards.
