Ontology based control of access to resources in a computing system

Abstract

A solution is proposed for controlling access to one or more resources of a computing system. A corresponding method comprises storing a knowledge base, which provides a knowledge of an access control to the resources in conformity with an access control ontology. In response to an update request, the access control ontology is updated according to update assertions obtained from the update request. In response to an access request (for a selected access to a selected resource), the selected access is granted or denied according to a result of an access query (for querying the access control ontology) obtained from the access request. A computer program and a computer program product for performing the method are also proposed. Moreover, a corresponding system (particularly, a control computing machine) is proposed.
