What minimum TLS version is required for Azure security compliance?

The minimum TLS version required for Azure security compliance is TLS version 1.2. This version of the Transport Layer Security (TLS) protocol offers enhanced security features compared to its predecessors. TLS 1.2 introduced significant improvements in encryption algorithms and security measures, making it more resistant to certain types of attacks. It also supports more secure cipher suites, which provide better protection for data in transit.

Using TLS 1.2 ensures that the communications between clients and Azure services are secured effectively, aligning with industry standards for security compliance, such as those set by various regulatory bodies. As a result, organizations utilizing Azure services are encouraged to implement TLS 1.2 as a baseline to maintain the integrity and confidentiality of their data, allowing them to meet compliance requirements.

While versions 1.0 and 1.1 were previously acceptable, they are now considered outdated and vulnerable to security risks, which is why they do not meet current compliance standards. TLS version 1.3, while offering additional improvements, is not the minimum requirement for compliance, so TLS 1.2 remains the baseline standard in use for current Azure services.
