information will apply to earlier versions of SQL Server, back to SQL Server 2005, because that's where Microsoft revolutionized security in the product. But I will also discuss features only in SQL Server 2012 and later versions

Encryption on SQLServer built-in encryption on SQLServer is used to protect various types of sensitive data. In many cases, this encryption is completely transparent to you. When data is stored, it is encrypted and used automatically. In other cases, you can choose whether the data is encrypted. SQLServer can encrypt the following components:

When a user database is available and TDE is enabled, encryption is implemented at the page level when it is written to disk. Decrypts when the data page is read into memory. If a database file or database backup is stolen, the original certificate that is not used for encryption will not be accessible. This is almost the most exciting feature of the

secure than its previous version, it is possible for an attacker to obtain stored data. As a result, data encryption becomes a more thorough data protection strategy, and even if an attacker is able to access data, it has to be decrypted, thus adding a layer of protection to the data.
