TLS 1.2 afdwingen voor Microsoft Entra Connect

De TLS-protocolversie 1.2 (Transport Layer Security) is een cryptografieprotocol dat is ontworpen om beveiligde communicatie te bieden. Het TLS-protocol is voornamelijk gericht op het bieden van privacy en gegevensintegriteit. TLS heeft veel iteraties doorlopen, waarbij versie 1.2 wordt gedefinieerd in RFC 5246. Microsoft Entra Connect versie 1.2.65.0 en hoger biedt nu volledige ondersteuning voor alleen TLS 1.2 voor communicatie met Azure. Dit artikel bevat informatie over het afdwingen van uw Microsoft Entra Connect-server om alleen TLS 1.2 te gebruiken.

Belangrijk

Voor versie 2.3.20.0 of hoger is TLS 1.2 vereist. Zorg ervoor dat TLS 1.2 is ingeschakeld voordat u deze versie bijwerkt.

Notitie

Als TLS 1.2 niet is ingeschakeld op uw server, moet u dit inschakelen voordat u Microsoft Entra Connect V2.0 kunt implementeren.

Het register bijwerken

Als u wilt afdwingen dat de Microsoft Entra Connect-server alleen TLS 1.2 gebruikt, moet het register van de Windows-server worden bijgewerkt. Stel de volgende registersleutels in op de Microsoft Entra Connect-server.

Belangrijk

Nadat u het register hebt bijgewerkt, moet u de Windows-server opnieuw opstarten om de wijzigingen van kracht te laten worden.

PowerShell-script om TLS 1.2 te controleren

U kunt het volgende PowerShell-script gebruiken om de huidige TLS 1.2-instellingen op uw Microsoft Entra Connect-server te controleren.
