For maximum security, ensure that your Oracle Cloud Infrastructure (OCI) KMS Vaults are provisioned on an isolated partition of the Hardware Security Module (HSM) to achieve single-tenant isolation and prevent logical access or key compromise from other tenants sharing the physical hardware.
optimisation
Oracle Cloud Infrastructure (OCI) KMS Vaults should reside on an isolated partition within an HSM (using a Virtual Private Vault) when sensitive workloads require dedicated isolation and stringent compliance, as an OCI KMS Virtual Private Vault provides its own secure HSM partition, offering stronger isolation and backup capabilities, unlike shared vaults that trade isolation for lower cost and pay-per-key flexibility.
Audit
To determine if your Oracle Cloud Infrastructure (OCI) KMS Vaults are Virtual Private Vaults, perform the following operations:
Remediation / Resolution
To ensure that your OCI KMS Vaults are deployed to an isolated partition within a Hardware Security Module (HSM), you must re-create the vaults with the appropriate configuration. To create Virtual Private Vaults, perform the following operations:
