Scenarios

Risk level
Default risk level: low.
You can change the risk level as required when you apply this rule.
Compliance evaluation logic

- If one or more ECS data disks are not attached to ECS instances, the evaluation result is non-compliant. For more information about how to correct the non-compliant configuration, see Non-compliance remediation.
