Public preview: Control the minimum TLS version used with Azure Service Bus
Publiseringsdato: 05 mai, 2022
Communication between a client application and an Azure Service Bus namespace is encrypted using Transport Layer Security (TLS). Transport Layer Security is a standard cryptographic protocol that ensures privacy and data integrity between clients and services over the Internet.
Azure Service Bus supports choosing a specific TLS version for namespaces. Currently Azure Service Bus uses TLS 1.2 on public endpoints by default, but TLS 1.0 and TLS 1.1 are still supported for backward compatibility.
Azure Service Bus namespaces permit clients to send and receive data with TLS 1.0 and above. To enforce stricter security measures, you can configure your Service Bus namespace to require that clients send and receive data with a newer version of TLS. If a Service Bus namespace requires a minimum version of TLS, then any requests made with an older version will fail.
