TDE (Transparent Data Encryption) is a feature that helps to protect the data on the SQL database by encrypting the data that is being written to the disk and decrypting the data that is being read from the disk to memory. It was found that the instance '{AliCloudRdsDbInstance}' doesn't have TDE enabled and therefore the data at rest is might have a greater chance of being the subject of malicious activity.
