**Id:** `ed6e3ba0-278f-47b6-a1f5-173576b40b7e`

#### Learn More{% #learn-more %}

- [Provider Reference](https://registry.terraform.io/providers/aliyun/alicloud/latest/docs/resources/kms_key#is_enabled)

### Description{% #description %}

Alicloud KMS must only include enabled Customer Master Keys (CMKs). This rule flags `alicloud_kms_key` resources when:

- `is_enabled` is explicitly set to false (`IncorrectValue`), or
- `is_enabled` is missing (`MissingAttribute`)

To remediate, set or update `is_enabled = true`.

## Compliant Code Examples{% #compliant-code-examples %}

```terraform
resource "alicloud_kms_key" "key" {
  description             = "Hello KMS"
  pending_window_in_days  = "7"
  status                  = "Enabled"
  is_enabled              = true
}
```

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

  pending_window_in_days  = "7"
  status                  = "Enabled"
  is_enabled              = false
