Access Control Infrastructure for On-Demand Provisioned Virtualised Infrastructure Services

Cloud technologies are emerging as a new way of provisioning virtualised computing and infrastructure services on-demand for collaborative projects and groups. Security in provisioning virtual infrastructure services should address two general aspects: supporting secure operation of the provisioning infrastructure, and provisioning a dynamic access control infrastructure as part of the provisioned on-demand virtual infrastructure. Dynamically provisioned Access Control Infrastructure (DACI) reveals a wide spectrum of problems related to the distributed access control, policy and related security context management. Consistent security services design, deployment and operation require continuous security context management during the whole security services lifecycle, which is aligned to the main provisioned services lifecycle.
