Coordinating Accessibility versus Restrictions in Distributed Object Systems
نویسندگان
چکیده
This work aims to provide administrators with services for managing permissions in a distributed object system, by connecting business-level tasks to access controls on low level functions. Specifically, the techniques connect abilities (to complete externallyinvoked functions) to the access controls on individual functions, across all servers. Our main results are the problem formalization, plus algorithms to synthesize “least privilege” permissions for a given set of desired abilities. Desirable extensions and numerous research issues are identified.

Using Scoping Rules as a Distributed Coordination Language
Keywords: coordination languages, Scheme, distributed systems, lexical scoping, distributed objects. Essential to coordinating a distributed application is organizing and traversing the distributed application graph. Lexical scoping performs this function among modern high-level programming languages, but does not have the same distinction in distributed programming systems, where it competes w...
متن کاملCoordinating Distributed CLP-Solvers in Medical Appointment Scheduling
Research on monolithic logic-based systems has usually left out an important aspect of information technology systems supporting medical processes — distribution. Often social restrictions build up by questions of authority prohibit the implementation of global systems with omniscient view. Hence, IT in medical domains has to obey these restrictions by being distributed as well. The direct cons...
متن کاملA Hierarchical Distributed Coiitrol Model for Coordinating Intelligent Systeiiis
This paper describes a hierarchical distributed control (HDC) model for coordinating cooperative problem-solving among intelligent systems. The model was implemented using SOCIAL, an innovative object-oriented tool for integrating heterogeneous, distributed software systems. SOCIAL embeds applications in “wrapper” objects called Agents, which supply predefined capabilities for distributed commu...
متن کاملA Catalyst for Distributed Communities of Practice
Symbiotic computing leads to a proliferation of computing devices that allow linking people, favoring the development of distributed Communities of Practice (CoPs). Their members, being dispersed geographically, have to rely strongly on technological means to interact. In this context, coordinating distributed CoPs is more challenging than coordinating their collocated counterparts. Hence, the ...
متن کاملA Distributed Architecture for Environmental Information Systems
The increasing availability and variety of large environmental data sets is opening new opportunities for data mining and useful cross-referencing of disparate environmental data sets distributed over a network. In order to take advantage of these opportunities, environmental information systems will need to operate effectively in a distributed, open environment. In this paper, we describe the ...
