Derivation and use of trust and risk management parameters in dynamic federated environments
Traditionally, the risks associated with granting customers and their users access to services and resources are mitigated by contractual frameworks, such as service level agreements (SLAs). However, in large and highly dynamic federated environments, also external and previously unknown users must be handled in an automated manner, which limits the available options to negotiate SLAs. In this paper we present how risk management on the service provider side and user trust level management frameworks can be combined and applied to policy-based access control mechanisms.
