Checks whether the disk encryption feature is enabled for each ApsaraDB RDS instance. If so, the evaluation result is Compliant.
Scenarios
You can use the disk encryption feature provided by Alibaba Cloud on ApsaraDB RDS instances free of charge. The disk encryption feature helps you encrypt the data in the disks of your ApsaraDB RDS instances based on block storage. This way, backup data cannot be decrypted even if the data is leaked. This ensures data security.
Risk level

When you apply this rule, you can change the risk level based on your business requirements.
