Ensure Block Volumes are encrypted with Customer Managed Keys (CMK).

HochStufe 2Automatisiertoci

Beschreibung

Oracle Cloud Infrastructure Block Volume service lets you dynamically provision and manage block storage volumes. By default, the Oracle service manages the keys that encrypt block volumes. Block Volumes can also be encrypted using a customer managed key. Encryption of block volumes provides an additional level of security for your data. Management of encryption keys is critical to protecting and accessing protected data. Flags block volumes without a kms-key-id. Covers every subscribed region and every accessible compartment. Read-only OCI CLI calls; credentials and home region come from the CLI's normal configuration (~/.oci/config, OCI_CLI_PROFILE, OCI_CLI_AUTH). The tenancy OCID is taken from OCI_TENANCY or the first tenancy= line of the config file. A missing CLI or credential fails the check.

So wird behoben

Behebungsmethode: Anleitung oder Infrastruktur-Patch

oci bv volume-kms-key update --volume-id <ocid> --kms-key-id <vault-key-ocid> for each listed block volume.
