Ensure automatic rotation is enabled for customer created symmetric KMS keys

MediaNivel 2Automatizadaalibaba

Descripción

Automatic rotation limits the amount of data protected by one key version. In the profile's region, every Enabled symmetric (Aliyun_AES_256 / Aliyun_SM4) key created by the account must have AutomaticRotation Enabled; service-created default keys are skipped. Read-only aliyun CLI calls; credentials and default region come from the CLI's normal profile (aliyun configure, ~/.aliyun/config.json or ALIBABA_CLOUD_* environment variables). JSON output is parsed with grep/sed/awk. A missing CLI or credential fails the check.

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

aliyun kms UpdateRotationPolicy --KeyId <key-id> --EnableAutomaticRotation true --RotationInterval 31536000s (or a shorter interval) for each listed key.
