Drop support for TLS 1.0 and 1.1?

[theMusician]

Hi,

Our security scan noticed that TLS 1.0 and 1.1 are possibly active. Sometimes we get false positives but wanted to share it. Generally we would enable support for TLS 1.2 and 1.3, and disable support for TLS 1.0 and 1.1.

Thank you for looking at it.

Info from our scan

TLS Version 1.0 Protocol Detection

The remote service accepts connections encrypted using TLS 1.0. TLS 1.0 has a number of cryptographic design flaws. Modern implementations of TLS 1.0 mitigate these problems, but newer versions of TLS like 1.2 and 1.3 are designed against these flaws and should be used whenever possible.

As of March 31, 2020, Endpoints that aren't enabled for TLS 1.2 and higher will no longer function properly with major web browsers and major vendors. PCI DSS v3.2 requires that TLS 1.0 be disabled entirely by June 30, 2018, except for POS POI terminals (and the SSL/TLS termination points to which they connect) that can be verified as not being susceptible to any known exploits.

TLS Version 1.1 Protocol Deprecated

The remote service accepts connections encrypted using TLS 1.1. TLS 1.1 lacks support for current and recommended cipher suites. Ciphers that support encryption before MAC computation, and authenticated encryption modes such as GCM cannot be used with TLS 1.1 As of March 31, 2020, Endpoints that are not enabled for TLS 1.2 and higher will no longer function properly with major web browsers and major vendors.
