Policy: Azure > CIS v3.0 > 08 - Virtual Machines > 08.02 - Ensure Virtual Machines are utilizing Managed Disks

Configures auditing against a CIS Benchmark item.

Level: 1

Migrate blob-based VHDs to Managed Disks on Virtual Machines to exploit the default features of this configuration. The features include: 1. Default Disk Encryption 2. Resilience, as Microsoft will managed the disk storage and move around if underlying hardware goes faulty 3. Reduction of costs over storage accounts

Managed disks are by default encrypted on the underlying hardware, so no additional encryption is required for basic protection. It is available if additional encryption is required. Managed disks are by design more resilient that storage accounts. For ARM-deployed Virtual Machines, Azure Adviser will at some point recommend moving VHDs to managed disks both from a security and cost management perspective.
