ABSTRACT:
An authorization architecture for authorizing access to resource objects in an object-oriented programming environment. In one distributed environment, the permission model of JAAS (Java Authentication and Authorization Service) is replaced or enhanced with role-based access control. Thus, users and other subjects (e.g., pieces of code) are assigned membership in one or more roles, and appropriate permissions or privileges to access resource objects are granted to those roles. Permissions may also be granted directly to users. Roles may be designed to group users having similar functions, duties or similar requirements for accessing the resources. Roles may be arranged hierarchically, so that users explicitly assigned to one role may indirectly be assigned to one or more other roles (i.e., descendants of the first role). A realm or domain may be defined as a namespace, in which one or more role hierarchies are established.
