Aktivera sårbarhetsbedömningar i Azure SQL-databaser med expresskonfigurationen
Det här PowerShell-skriptet möjliggör expresskonfiguration av sårbarhetsbedömningar på en Azure SQL Server.
Om sårbarhetsbedömning redan har konfigurerats med den klassiska konfigurationen migrerar det här skriptet till expresskonfigurationen och kopierar alla befintliga baslinjedefinitioner. Din genomsökningshistorik kopieras inte till den nya konfigurationen. Din genomsökningshistorik är fortfarande tillgänglig för lagringskontot som tidigare användes av den klassiska konfigurationen.
Förutsättningar
Det här exemplet kräver Azure PowerShell Az 1.0 eller senare. Kör Get-Module -ListAvailable Az för att se vilka versioner som är installerade.
Om du behöver installera kan du läsa Installera Azure PowerShell-modulen.
Kör Anslut-AzAccount för att logga in på Azure.
Om du inte har en Azure-prenumeration skapar du ett kostnadsfritt Azure-konto innan du börjar.
Användaren bör ha
Storage Blob Data Readerrollen för lagringskontot.Inställningar för lagringsnätverk måste konfigureras för att tillåta åtkomst till den dator som kör kommandot.
Du måste ha behörighet att skapa mappar i arbetskatalogen som används av skriptet.

Kommentar
Vi rekommenderar att du använder Azure Az PowerShell-modulen för att interagera med Azure. Se Installera Azure PowerShell för att komma igång. Information om hur du migrerar till Az PowerShell-modulen finns i artikeln om att migrera Azure PowerShell från AzureRM till 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.
