SQL Alerts

Events are generated by SQL Server and entered into the Microsoft Windows application log. SQL Server Agent reads the application log and compares events written there to alerts that you have defined. When SQL Server Agent finds a match, it fires an alert, which is an automated response to an event. In addition to monitoring... » read more

Note: Certificate is different for different databases. USE master database for TDE certificate. If expiration date not specified, default to 1 year. Note that there are several certificates listed, including one that looks like it’s for authentication (##MS_SQLAuthenticatorCertificate##). This is where SQL Server stores its certificates, in the master database. Obviously, if you create an... » read more

Database Master Key (DMK)

Note: Is is the Database Master Key (DMK). It is not the Service Master Key (SMK). The database master key is a symmetric key used to protect the private keys of certificates and asymmetric keys that are present in the database. When it is created, the master key is encrypted by using the AES_256 algorithm and a user-supplied password. Database master key is stored in both... » read more

Service Master Key (SMK)

Note: This is for Service Master Key (SMK). This is not the same as Database Master Key (DMK). The service master key is the root of the SQL Server encryption hierarchy. The service master key directly or indirectly secures all other keys in the tree. If a dependent key cannot be decrypted during a forced... » read more

TDE and Encryption Keys

SQL Server uses encryption keys to help secure data, credentials, and connection information that is stored in a server database. SQL Server has two kinds of keys: symmetric and asymmetric. Symmetric keys use the same password to encrypt and decrypt data. Asymmetric keys use one password to encrypt data (called the public key) and another to decrypt data (called... » read more

TDE and Database Backup and Recovery

Back up the master key and certificate that are used for TDE to a safe location. The master key and certificate are required to restore backups that were taken when the database was encrypted with TDE. After you remove the database encryption key, take a log backup followed by a fresh full backup of the... » read more

TDE and Always On Setup

TDE and Always On To configure the TDE on the TDE_Test database, we should first create a master key in the master database. Only one master key can be created per each SQL Server instance. All user databases that are hosted in the same SQL instance, and have the TDE enabled on it, will share... » read more
