Abstract

A resource access security system for use in a data processing system for controlling access to resources correspondingly assigned to addresses in an address space of the data processing system by the use of descriptors. The descriptors correspondingly identify the resources and access to the resources is controlled by requiring the input of a descriptor of the resource to which access is sought. The resource access security system controls access to the resources by translating each descriptor being taught to gain access to a resource by use of a plurality of tables having stored therein user/job information, domain information and page information and a descriptor translator which controls the descriptor translation process. The descriptors are virtual addresses of addresses assigned to the resources of the data processing system.
