Control: Azure > CIS v5.0 > 7 - Networking Services > 7.12 - Ensure the SSL policy's 'Min protocol version' is set to 'TLSv1_2' or higher on Azure Application Gateway

Configures auditing against a CIS Benchmark item.

Level: 1

The TLS (Transport Layer Security) protocol secures the transmission of data over the internet using standard encryption technology. Application gateways use TLS 1.2 for the Min protocol version by default and allow for the use of TLS versions 1.0, 1.1, and 1.3. NIST strongly suggests the use of TLS 1.2 and recommends the adoption of TLS 1.3.

TLS 1.0 and 1.1 are outdated and vulnerable to security risks. Since TLS 1.2 and TLS 1.3 provide enhanced security and improved performance, it is highly recommended to use TLS 1.2 or higher whenever possible.
