Abilitare le valutazioni delle vulnerabilità nei database SQL di Azure con la configurazione rapida
Questo script di PowerShell consente la configurazione rapida delle valutazioni delle vulnerabilità in un'istanza di SQL Server di Azure.
Se la valutazione della vulnerabilità è già stata configurata usando la configurazione classica, questo script esegue la migrazione alla configurazione rapida e copia tutte le definizioni di base preesistenti. La cronologia dell'analisi non viene copiata nella nuova configurazione. La cronologia di analisi rimane accessibile nell'account di archiviazione usato in precedenza dalla configurazione classica.
Prerequisiti
Questo esempio richiede Azure PowerShell Az 1.0 o versioni successive. Eseguire Get-Module -ListAvailable Az per determinare le versioni installate.
Se è necessario installarlo, vedere Installare il modulo Azure PowerShell.
Eseguire Connect-AzAccount per accedere ad Azure.
Se non si ha una sottoscrizione di Azure, creare un account Azure gratuito prima di iniziare.
L'utente deve avere
Storage Blob Data Readeril ruolo nell'account di archiviazione.Archiviazione le impostazioni di rete devono essere configurate per consentire l'accesso al computer che esegue il comando.
È necessario disporre dell'autorizzazione per creare cartelle nella directory di lavoro usata dallo script.
Script di esempio - MigratingToExpressConfiguration.ps1
Nota
È consigliabile usare il modulo Azure Az PowerShell per interagire con Azure. Per iniziare, vedere Installare Azure PowerShell. Per informazioni su come eseguire la migrazione al modulo AZ PowerShell, vedere Eseguire la migrazione di Azure PowerShell da AzureRM ad Az.

.SYNOPSIS
This script configured an Azure SQL Server to the express configuration Vulnerability Assessment feature, scans all databases that belong to the selected server and set baselines (if defined in classic configuration) from the storage that is configures in the policy.
.DESCRIPTION
This script migrates Azure SQL Server to express configuration Vulnerability Assessment feature by executing the following steps:
- It deletes the current Vulnerability Assessment settings (if exists).
This step will reset all the Vulnerability Assessment scans and baselines for all databases.
- It copies the current baselines (if exist) from the customer's storage.
In order to revert this script follow the instructions as mentioned here: https://learn.microsoft.com/azure/defender-for-cloud/sql-azure-vulnerability-assessment-manage?tabs=express#revert-back-to-the-classic-configuration.
.PARAMETER ServerSubscriptionId
The Subscription id that the server belongs to
.PARAMETER ServerResourceGroupName
The Resource Group that the server belongs to
.PARAMETER ServerName
The SQL server name that we want to apply the new SQL Vulnerability Assessment policy to.
.PARAMETER Force
Will remove the old Vulnerability Assessment setting without asking for confirmation.
