Security Architecture for Open Collaborative Environment

Abstract. The paper presents proposed Security Architecture for Open Collaborative Environment (OCE) being developed in the framework of the Collaboratory.nl (CNL) project with the intent to build a flexible, customer-driven security infrastructure for open collaborative applications. The architecture is based on extended use of emerging Web Services and Grid security technologies combined with concepts from the generic Authentication Authorization and Accounting (AAA) and Role-based Access Control (RBAC) frameworks. The paper describes another proposed solution the Job-centric security model that uses a Job description as a semantic document created on the basis of the signed order (or business agreement) to provide a job-specific context for invocation of the basic OCE security services. Typical OCE use case of policy based access control is discussed in details.
