Therefore, if either file is copied or stolen via a network, as in the above example, the attacker cannot read it. With TDE alone, the database files themselves are encrypted (as well as backup files of the TDE-encrypted databases). The copy of this file on the new drive is then not encrypted anymore. On the other hand, if someone gained access to the drive via a network a share or other services that share data from the drive, they could copy data (for example, an SQL Server backup file or a database file) unless it's locked from doing so by the running SQL Server process. But if the drive gets stolen, nobody can use the data without access to the key. The effect is that a user process, like SQL Server, running on the machine can access data on the drive as if it were not encrypted at all.

If a malicious party would be able to steal your data files, they still would not be able to use them at all because they would need the keys as well.īe aware that detaching or backing up a database to a different volume that is not protected by BitLocker causes any protection the file currently has to be lost.įor more information about BitLocker, see the overview and how it applies to Windows Server 2012 and later Defense in depth with BitLocker Drive Encryption and Transparent Data Encryption (TDE) combinedīitLocker encrypts the entire drive and is integrated in the OS. TDE can help the ability to comply with many laws, regulations, and guidelines established in various industries. TDE performs real-time I/O encryption and decryption of the data and log files to protect data at rest. With TDE you can encrypt the sensitive data in the database and protect the keys that are used to encrypt the data with a certificate. You can use Transparent Data Encryption (TDE) to encrypt SQL Server and Azure SQL Database data files at rest. SQL Server offers the Always Encrypted feature for this, but it's not supported for Business Central.
It also doesn't provide encryption while the data is in use.

For more information about how to encrypt data across the communication channel between the database and the Business Central Server, see Enhancing Business Server Security. Data encryption at rest does not provide encryption across communication channels.
