KMS keys have rotation enabled

kms_key_rotation_enabled
Service: kmsSeverity: medium
OfficialBuilt-inVerified
Categories:encryption
Resource Type:NotDefined

Ensure that Huawei Cloud Key Management Service (KMS) keys have automatic key rotation enabled to regularly rotate the cryptographic material.

Prowler logoProwlerprowler-provider-huaweicloud

Risk

Without key rotation, the same cryptographic material is used indefinitely, increasing the risk of key compromise over time. If a key is compromised, all data encrypted with that key version is at risk.

Run this check with Prowler

Run in Prowler Cloud
Run
prowler huaweicloud --checks kms_key_rotation_enabled

Recommendation

Enable automatic key rotation for all KMS keys.

Remediation

CLI

hcloud KMS EnableKeyRotation --key_id=<key_id>

Other

1Log on to the **Huawei Cloud console**.
2Navigate to **Key Management Service**.
3Select the key.
4Click the **Rotation** tab.
5Enable **rotation** and set the rotation period.
6Click **OK**.
