Abstract: A tag-based policy architecture enforces information technology (IT) policy in a virtualized computing environment using cryptographically-verifiable metadata to authenticate compute resources coupled to a computer network and to authorize access to protected resources of the network. The compute resources are illustratively virtual machine instances (VMIs) provided by a virtual data center (VDC) of the environment, whereas the protected resources are illustratively virtualized storage, network and/or other compute resources of the VDC. Each VMI includes an intermediary manager, e.g., metavisor. The tag-based policy architecture includes an infrastructure having a centralized policy decision end point (e.g., a control plane of the VDC) and distributed policy enforcement endpoints (e.g.

Abstract: A technique implements data policy deployed in a tag-based policy architecture of a virtualized computing environment. Implementation of the data policy may include applying volume tags to data stored on virtualized storage resources, such as disks organized as volumes, based on instances that generate the data, contents of the data, and/or sensitivity of the data. The volume tags may be applied in a cryptographically strong manner to prevent tampering of the tagged data. To that end, the volume tags are cryptographically associated with the data, wherein such association is effected by binding the tags to a data encryption key stored on the volumes (disks) and used to encrypt/decrypt the data stored on the volumes.
