Cloud computing is emerging as a virtual model in support of “everything-as-a-service” (XaaS). There are numerous providers such as feeders, owners and creators who are less likely the same actor, and multiple platforms possibly with different security control mechanisms. Consequently, cloud resources cannot be securely managed by traditional access control models. In this paper, we propose a new security technique to enable a multifactor access control, and to cope with various deployment models where user’s network and system sessions may vary. Using the metadata of resources and access policies, the technique builds the privilege chains. The contribution of this paper includes a mechanism of the privilege chains that can be used to verify the trustiness of cloud resources and to protect the resources from unauthorized access.
