Dieser Artikel hilft Ihnen, bestimmte Protokolle zu deaktivieren, um PCI-Compliance-Scans (Payment Card Industry) mithilfe von Windows® PowerShell® zu bestehen.
Der folgende Skriptblock enthält Elemente, die Mechanismen zur Schwächung der Verschlüsselung mithilfe von Registrierungsänderungen deaktivieren. Einzelheiten finden Sie in den Kommentaren zum Skriptblock. Nachdem Sie irgendein Element des Skripts ausgeführt haben, müssen Sie den Windows-Server neu starten, um die Änderungen vollständig zu übernehmen.
