Architecting Dependable Access Control Systems for Multi-domain Computing Environments

摘要: Modern computing systems are built based on Service Oriented Architectures and made up of multiple distributed components. They often span separate autonomous domains administration involve dynamic collaboration. Resources services exposed as Web Services that a natural choice for achieving interoperability in heterogeneous environment. Access control ensure protected against unauthorised access. Architecting such multi-domain environments poses numerous challenges must be considered. Such modular, extensible should have reusable Authorisation needs to administration, scale large user resource bases efficient enough handle even fine-grained interactions between highly components. In this paper we present requirements analysis architecting dependable access environments. In particular, address those SOA use the underlying connection technology. We refer relevant standards technologies significant importance when
