Java EE Security API 1.0

Java EE Security API provides portable interfaces for HTTP authentication and identity stores, and a context aware SecurityContext which can be injected into other beans and allow you customize security programmatically.

HttpAuthenticationMechanism is used for authenticating users from applications.

IdentityStore is used for validating user credentials and retrieve its group information.

SecurityContext is used for querying the current security context in any context, eg. Servlet, JAX-RS, EJB etc.

Beside these, such as Authenticaiton, Authorization, UserPricinpal, Realm etc are very similar with the terminology from Apache Shiro.
