Abstract: Access to data and resources in a multi-tenant computing system is managed by tagging the data and resources with attributes, as well as by tagging users with attributes. Tenant-specific access policies are configured. When an access request is received from a workload, a policy decision engine processes the attributes that are tagged to the requesting workload (e.g., user, application, etc.) as well as those tagged to the requested data or resource, given a relevant tenant-specific policy. An access decision is provided in response to the access request, and the access decision can be enforced by a tenant-specific enforcement system.

Abstract: Double key encryption encrypts sensitive data using a content key, obtains a user public key from a key management service, encrypts the content key using the user public key, and encrypts the result using a cloud service provider key. Data confidentiality is protected efficiently through multilevel encryption and also by utilizing keys that are managed by different entities. Sensitivity labeling allows analytics to track sensitive data without compromising confidentiality. Compliance mechanisms may use attribute-based access control to support storage of sensitive data in a cloud, but only inside a permitted region, and without giving the cloud service provider access to the sensitive data.
