Description​

Enable Transparent Data Encryption on every SQL server.

Rationale​

Azure SQL Database transparent data encryption helps protect against the threat of malicious activity by performing real-time encryption and decryption of the database, associated backups, and transaction log files at rest without requiring changes to the application.

Audit​

From Azure Portal​
  1. Go to SQL databases.
  2. For each DB instance, under Security, click Data Encryption.
  3. Under Transparent data encryption, ensure that Data encryption is set to On.
From Azure CLI​

Ensure the output of the below command is Enabled:

az sql db tde show --resource-group <resourceGroup> --server <dbServerName> --database <dbName> --query status
From PowerShell​

Get a list of SQL Servers:

Get-AzSqlServer

For each server, list the databases:

Get-AzSqlDatabase -ServerName <SQL Server Name> -ResourceGroupName <Resource Group Name>

For each database not listed as a Master database, check for Transparent Data Encryption:

Remediation​

From Azure Portal​

  1. Go to SQL databases.
  2. For each DB instance, under Security, click Data Encryption.
  3. Under Transparent data encryption, set Data encryption to On.
  4. Click Save.

From Azure CLI​

Use the below command to enable Transparent data encryption for SQL DB instance:

az sql db tde set --resource-group <resourceGroup> --server <dbServerName> --database <dbName> --status Enabled

From PowerShell​

Use the below command to enable Transparent data encryption for SQL DB instance:

Set-AzSqlDatabaseTransparentDataEncryption -ResourceGroupName <Resource Group Name> -ServerName <SQL Server Name> -DatabaseName <Database Name> -State 'Enabled'

Note:

  • TDE cannot be used to encrypt the logical master database in SQL Database. The master database contains objects that are needed to perform the TDE operations on the user databases.
  • Azure Portal does not show master databases per SQL server. However, CLI/API responses will show master databases.
