A Proposal for Access Control Models for Multi-tenancy

This deliverable will assess current approaches for access control and propose novel models, based on current progress in ABAC models, to cope with multi-tenancy requirements and in particular with distributed attributes. A mapping between these ABAC-based models to enforceable policy languages (e.g. XACML) will be proposed, including the design of an enforcement component to parse, interpret and execute access control policies.
