Disabling TLS 1.0 and 1.1 in Java 11
This article explains how to disable the TLS 1.0 and 1.1 protocols used by Java 11.
Oracle disabled the TLS 1.0 and 1.1 cryptographic protocols in Java 11 on April 20, 2021. It is recommended that you disable any enabled TLS 1.0 and 1.1 protocols in your on-premise installation of Java 11. This will provide more secure communication via TLS 1.2.
In addition, if you have any workflows that are using TLS 1.0 or 1.1 connections (e.g., DEP, VPP, and the App Store), it is recommended that you disable the TLS 1.0 and 1.1 protocols.
