Imposição do TLS 1.2 para Microsoft Entra Connect
A versão 1.2 do protocolo TLS é um protocolo de criptografia que foi projetado para fornecer comunicação segura. O protocolo TLS tem como objetivo principal fornecer privacidade e integridade dos dados. O TLS passou por muitas iterações, com a versão 1.2 que está sendo definida em RFC 5246. O Microsoft Entra Connect versão 1.2.65.0 e posteriores agora têm suporte total para o uso apenas de TLS 1.2 para comunicação com o Azure. Este artigo fornece informações sobre como forçar o servidor do Microsoft Entra Connect a usar somente o TLS 1.2.
Importante
A versão 2.3.20.0 ou posterior requer TLS 1.2. Verifique se você tem o TLS 1.2 habilitado antes de atualizar para esta versão.
Observação
Se o TLS 1.2 não estiver habilitado no servidor, você precisará fazer isso antes de implantar o Microsoft Entra Connect V2.0.
Atualizar o Registro
Para forçar o servidor do Microsoft Entra Connect a usar somente o TLS 1.2, o registro do servidor Windows precisa ser atualizado. Defina as seguintes chaves de Registro no servidor do Microsoft Entra Connect.
Importante
Depois de atualizar o registro, você precisa reiniciar o servidor do Windows para que as alterações entrem em vigor.
