You may want to reference the Security Hardening Checklist which has instructions on how to disable previous versions of TLS (v1 and v1.1)
By default the highest available version of TLS in the browser will be used to make the connection to Tableau Server. Thus if TLS 1.2 is enabled in the browser, the connection will be made using TLS 1.2.
Thank you for the quick response. I’m wondering if there is a way to determine which versions are currently enabled. We have external users that access server and I do not know their browser settings. If the older versions are already disabled and I run the command referenced in the Security Hardening Checklist there should be no impact to users. And truthfully I probably would not run it at all if I knew the older versions were already disabled.
If some of my users do not currently have TLS 1.2 enabled on their browsers and I disable the older versions they may have a negative experience. If there was an easy way to know the current state of these settings it would be helpful for planning.
To clarify, unless the command referenced in the Security Hardening Checklist is executed, then you should consider the old versions of TLS as enabled on Tableau Server. If you want to disable specific versions, the command must be run to disable them explicitly.
Sounds good. I will proceed as if the old versions are currently enabled. Thank you.
