4.2.5 Ensure that Vulnerability Assessment (VA) setting 'Also send email notifications to admins and subscription owners' is set for each SQL Server (Automated)​

Profile Applicability​

• Level 1

Description​

Enable Vulnerability Assessment (VA) setting 'Also send email notifications to admins and subscription owners'.

Rationale​

VA scan reports and alerts will be sent to admins and subscription owners by enabling setting 'Also send email notifications to admins and subscription owners'. This may help in reducing time required for identifying risks and taking corrective measures.

Impact​

Enabling the Microsoft Defender for SQL features will incur additional costs for each SQL server.

Audit​

From Azure Portal​

  1. Go to SQL servers
  2. Select a server instance
  3. Click on Security Center
  4. Ensure that Microsoft Defender for SQL is set to Enabled
  5. Select Configure next to Enabled at subscription-level
  6. In Section Vulnerability Assessment Settings, Ensure Storage Accounts is configured.
  7. In Section Vulnerability Assessment Settings, Ensure Also send email notifications to admins and subscription owners is checked/enabled.

From Azure Powershell​

Get the list of all SQL Servers

Get-AZSqlServer

For each Server

Get-AzSqlServerVulnerabilityAssessmentSetting -ResourceGroupName <resource group name> -ServerName <server name>

Ensure that value for parameter EmailSubscriptionAdmin is set to true.

Sample Output:

ResourceGroupName : ResourceGroup01

ServerName : Server01

StorageAccountName : mystorage

ScanResultsContainerName : vulnerability-assessment

RecurringScansInterval : weekly

EmailSubscriptionAdmins : False

NotificationEmail : {}

Remediation​

From Azure Portal​

  1. Go to SQL servers
  2. Select a server instance
  3. Click on Security Center
    1. Select Configure next to Enabled at subscription-level
  5. In Section Vulnerability Assessment Settings, configure Storage Accounts if not already
