Azure SQL Database에 대한 취약성 평가를 위한 기준 설정

이 PowerShell 스크립트는 Azure SQL Server의 모든 데이터베이스에 대한 최신 취약성 평가 검사 결과를 기반으로 기준을 설정합니다.

이 샘플에는 Azure PowerShell Az 1.0 이상이 필요합니다. Get-Module -ListAvailable Az를 실행하여 설치된 버전을 확인합니다. 설치해야 하는 경우 Azure PowerShell 모듈 설치를 참조하세요.

.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.
