In: ServiceWave '08 - 1st European Conference on Towards a Service-Based Internet (Madrid, Spain, 2008). Proceedings, pp. 242 - 253. Springer-Verlag, 2008.
Access control techniques designed for single domain infrastructures, where users are known by domain administrators, provide considerable liberty in the usage of resources. This paradigm is not suitable for highly scalable and decentralised systems such as Grids and service oriented architectures (SOA), where resources are shared between domains, and users come from remote domains. One approach is to provide policy-driven autonomic solutions that operate a continuous monitoring of the usage of resources by users. This paper presents the services and tools offered by the GridTrust Security Framework (GSF). GSF addresses three layers of the next generation of grid (NGG) architecture: the Grid application layer, the Grid service middleware layer, and the Grid foundation layer. The framework is composed of security and trust services and tools provided at the middleware and Grid foundation middleware layers. Various business case studies are being developed to validate the GridTrust results.
