Can I disable TLS 1.1 protocol and earlier arcgis enterprise

DiegoLlamasOlivares — Thu, 21 Jul 2022 18:11:03 GMT

Hello everyone,

The IT department has notified us that they are going to enforce TLS 1.2. communications only on all windows servers (they will disable the 1.1 or earlier versions). Reading the Esri documentation on this, I understand that all of our ArcGIS Enterprise 10.8.1 and 10.9.0 implementations will not be affected by this action. I need to confirm if I am correct, so that I can notify IT to make these changes.

I found this, and i should be able to disable TLS 1.1 and before, but just to be 100% sure

HI @DiegoLlamasOlivares

I have kind of similar issue. IT team has notified security vulnebralities on scanning the server. Advised to disable TLS 1.0 and 1.1 . Can you guide how to disable this?

Regards,

Isaki

Hello,

I used some power shell code like this to disable some TLS protocols,
