TLS is a protocol that is used to safely communicate between the web browser and the Team Server. When you use the Team Server in combination with Java 11 Open JDK, TLS version 1.2 is enabled by default. Older versions of TLS, like 1.0 and 1.1 can be labeled as unsafe. If your company policy requires you to actively disable these protocols, there are two ways to do this. The first is the quick solution, the second is the recommended solution.

Add the correct protocol version to the wrapper.conf file

Add the following line to the wrapper.conf file in the conf folder of the Team Server installation and save the changes:

wrapper.java.additional.10 = -Dhttps.protocols=TLSv1.2

Disable older versions in Java

Disable older versions in Java, applying this change to all programs using your Java (so not only for the BiZZdesign Team Server). To do this, edit the java.security file. It can be found in the following location:

 ...../<java installation folder>/conf/security

Add the algorithms you want to disable to the jdk.tls.disabledAlgorithms property in the file and save the changes. For example, disabling TLS1.0 and TLS1.1 would look as follows:

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, \

EC keySize < 224, 3DES_EDE_CBC, anon, NULL, TLSv1, TLSv1.1
