Настройка базовых показателей для оценки уязвимостей в базах данных SQL Azure

Этот скрипт PowerShell настраивает базовые показатели на основе последних результатов проверки уязвимостей для всех баз данных в SQL Server Azure.

Для этого примера требуется Azure PowerShell Az 1.0 или более поздней версии. Запустите Get-Module -ListAvailable Az для просмотра установленных версий. Если необходимо выполнить установку, см. статью об установке модуля Azure PowerShell.

Пример скрипта

<#
.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.
