You can still use a certificate that exceeds its expiration date to encrypt and decrypt data with TDE.

You also might need the certificate for some operations until you do a full database backup. Although the database isn't encrypted, parts of the transaction log might remain protected. Keep the encrypting certificate even if you've disabled TDE on the database.

If the certificate becomes unavailable, or if you restore or attach the database on another server, you need backups of the certificate and private key. For more information about certificates, see SQL Server Certificates and Asymmetric Keys.Īfter you enable TDE, immediately back up the certificate and its associated private key. Information applicable to SQL ServerĪfter you secure a database, you can restore it by using the correct certificate. For more information on using TDE with SQL Database, see transparent data encryption with Azure SQL Database. To move a TDE database on SQL Database, you don't have to decrypt the database for the move operation. When you use TDE with SQL Database V12, SQL Database automatically creates for you the server-level certificate stored in the master database. TDE doesn't increase the size of the encrypted database. The pages in an encrypted database are encrypted before they're written to disk and are decrypted when read into memory.

The SQL Server Security Blog on TDE with FAQĮncryption of a database file is done at the page level.

Use SQL Server Connector with SQL Encryption Features.

Move a TDE Protected Database to Another SQL Server.

Get started with transparent data encryption (TDE) in Azure Synapse Analytics.

Transparent data encryption for SQL Database, SQL Managed Instance, and Azure Synapse Analytics.

For more information about how to encrypt data across communication channels, see Enable Encrypted Connections to the Database Engine (SQL Server Configuration Manager). TDE doesn't provide encryption across communication channels.

This ability lets software developers encrypt data by using AES and 3DES encryption algorithms without changing existing applications. It lets you follow many laws, regulations, and guidelines established in various industries. TDE protects data at rest, which is the data and log files. It's secured by a certificate that the server's master database stores or by an asymmetric key that an EKM module protects. The database boot record stores the key for availability during recovery. The encryption uses a database encryption key (DEK). TDE does real-time I/O encryption and decryption of data and log files. But you must plan this kind of protection in advance. This solution prevents anyone without the keys from using the data. One solution is to encrypt sensitive data in a database and use a certificate to protect the keys that encrypt the data.

Building a firewall around the database servers.īut a malicious party who steals physical media like drives or backup tapes can restore or attach the database and browse its data.

To help secure a database, you can take precautions like: This encryption is known as encrypting data at rest. Transparent data encryption (TDE) encrypts SQL Server, Azure SQL Database, and Azure Synapse Analytics data files. You may be able to get away with seeing if the storage layer has encryption that can be implemented.Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW) Find out what is required by the business, not managements "everything must be encrypted" and work towards that. But if you have encrypted the data using CLR or the application then you cannot do that and must decrypt every row.Įncryption is hard, don't roll your own. The advantage to using TDE is that SQL understands the encryption and you can search on the encrypted data directly because it is only encrypted on disk. Using the application layer to encrypt/decrypt the data on read and Triggers and CLR functions to do the encryption/decryption for you. I think the confusion is where you are seeing that you can implement column/cell encryption using Enterprise edition OR through alternative methods.

You have other options as the articles you reference mention, but they require work on your part to implement. If you have SQL Server Standard edition then you do not have Encryption built into the product.
