Eclipse Exousia implements Jakarta Authorization, a technology that defines a low-level SPI for authorization modules, which are repositories of permissions facilitating subject based security by determining whether a given subject has a given permission, and algorithms to transform security constraints for specific containers (such as Jakarta- Servlet or Enterprise Beans) into these permissions.
Eclipse Exousia provides default implementations of these authorization modules and algorithms, as defined and mandated by the Jakarta Authorization specification.
