Imposição do TLS 1.2 para o Microsoft Entra Connect
A versão 1.2 do protocolo Transport Layer Security (TLS) é um protocolo criptografia concebido para fornecer comunicações seguras. O protocolo TLS visa principalmente fornecer privacidade e integridade de dados. O TLS passou por muitas iterações, com a versão 1.2 a ser definida no RFC 5246. O Microsoft Entra Connect versão 1.2.65.0 e posterior suporta agora totalmente a utilização apenas do TLS 1.2 para comunicações com o Azure. Este artigo fornece informações sobre como forçar o servidor do Microsoft Entra Connect a utilizar apenas o TLS 1.2.
Nota
Todas as versões do Windows Server suportadas para o Microsoft Entra Connect V2.0 já estão predefinidas para o TLS 1.2. Se o TLS 1.2 não estiver ativado no servidor, terá de o ativar antes de poder implementar o Microsoft Entra Connect V2.0.
Atualizar o registo
Para forçar o servidor do Microsoft Entra Connect a utilizar apenas o TLS 1.2, o registo do servidor Windows tem de ser atualizado. Defina as seguintes chaves de registo no servidor do Microsoft Entra Connect.
Importante
Depois de atualizar o registo, tem de reiniciar o servidor Windows para que as alterações sejam afetadas.
