Ensure Object Storage Buckets are encrypted with a Customer Managed Key (CMK).

ÉlevéeNiveau 2Automatiséeoci

Description

Oracle Object Storage buckets support encryption with a Customer Managed Key (CMK). By default, Object Storage buckets are encrypted with an Oracle managed key. Encryption of Object Storage buckets with a Customer Managed Key (CMK) provides an additional level of security on your data by allowing you to manage your own encryption key lifecycle management for the bucket. Every bucket must have a kms-key-id (customer managed key). 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.

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

oci os bucket update --bucket-name <bucket> --kms-key-id <vault-key-ocid> (Bucket details > Encryption key > Assign) after granting Object Storage use of the key.
