Basislijnen instellen voor evaluatie van beveiligingsproblemen in Azure SQL-databases

Met dit PowerShell-script worden basislijnen ingesteld op basis van de meest recente scanresultaten voor de evaluatie van beveiligingsproblemen voor alle databases in een Azure SQL Server.

Voor dit voorbeeld is Azure PowerShell Az 1.0 of hoger vereist. Voer Get-Module -ListAvailable Az uit om te zien welke versies zijn geïnstalleerd. Als u PowerShell moet installeren, raadpleegt u De Azure PowerShell-module installeren.

Voer Connect-AzAccount uit om u aan te melden bij Azure.

Als u geen Azure-abonnement hebt, kunt u een gratis Azure-account maken voordat u begint.

Notitie

Het wordt aanbevolen de Azure Az PowerShell-module te gebruiken om te communiceren met Azure. Zie Azure PowerShell installeren om aan de slag te gaan. Raadpleeg Azure PowerShell migreren van AzureRM naar Az om te leren hoe u naar de Azure PowerShell-module migreert.

<#
.SYNOPSIS
    This script sets the results of the last successful scan as baseline for each database under the selected Azure SQL Server.

.DESCRIPTION
    This script check if the selected Azure SQL Server uses Vulnerability Assessment Express Configuration, iterates through all user databases under a server and sets the latest scan results as a baseline.
