Unencrypted managed disk detectedTF-AZU003
Azure managed disks automatically encrypt your data by default when persisting it to the cloud. Server-side encryption protects your data and helps you meet your organizational security and compliance commitments. Data in Azure managed disks is encrypted transparently using 256-bit AES encryption, one of the strongest block ciphers available, and is FIPS 140-2 compliant. By default, managed disks use platform-managed encryption keys. As of June 10, 2017, all new managed disks, snapshots, images, and new data written to existing managed disks are automatically encrypted-at-rest with platform-managed keys. You can choose to manage encryption at the level of each managed disk, with your own keys. Server-side encryption for managed disks with customer-managed keys offers an integrated experience with Azure Key Vault. You can either import your RSA keys to your Key Vault or generate new RSA keys in Azure Key Vault.
