An authorization mechanism allows enhancement. The mechanism is applicable in a capability-based addressing system and allows definition of additional operation access rights to the existing system authorization model. Capability-based addressing systems are characterized by a resource-based approach toward computing. A resource in this instance refers to an identifiable and isolatable storage structure within a system (e.g., programs, files, processes). This is a method of structuring systems based on abstraction. These abstractions are composed of a set of resources and a specific set of operations for each type of resource (each type collectively referred to as a resource manager). By appropriate structuring of the system, the resource is isolated such that the resource is affected by operations defined on it.
