6.1. About Security Domains
Security domains are part of the JBoss EAP 6 security subsystem. All security configuration is now managed centrally, by the domain controller of a managed domain, or by the standalone server.
A security domain consists of configurations for authentication, authorization, security mapping, and auditing. It implements Java Authentication and Authorization Service (JAAS) declarative security.
Authentication refers to verifying the identity of a user. In security terminology, this user is referred to as a principal. Although authentication and authorization are different, many of the included authentication modules also handle authorization.
An authorization is a security policy, which contains information about actions which are allowed or prohibited. In security terminology, this is often referred to as a role.
Security mapping refers to the ability to add, modify, or delete information from a principal, role, or attribute before passing the information to your application.
The auditing manager allows you to configure provider modules to control the way that security events are reported.
If you use security domains, you can remove all specific security configuration from your application itself. This allows you to change security parameters centrally. One common scenario that benefits from this type of configuration structure is the process of moving applications between testing and production environments.
