Konfigurowanie punktów odniesienia na potrzeby ocen luk w zabezpieczeniach w bazach danych Azure SQL Database

Ten skrypt programu PowerShell konfiguruje punkty odniesienia na podstawie najnowszych wyników skanowania oceny luk w zabezpieczeniach dla wszystkich baz danych w programie Azure SQL Server.

Ten przykład wymaga modułu Az programu Azure PowerShell w wersji 1.0 lub nowszej. Uruchom polecenie Get-Module -ListAvailable Az , aby zobaczyć, które wersje są zainstalowane. Jeśli musisz zainstalować, zobacz Instalowanie modułu programu Azure PowerShell.

Uruchom polecenie Connect-AzAccount , aby zalogować się do platformy Azure.

<#
.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.
