![]() ![]() ![]() Enable use of TLS 1.2 by default for client and server connection.Disable the ability to use TLS 1.1 (you can still allow it if that’s your preference later).Since you have to do this on multiple servers it becomes difficult to manage and track which server has what TLS version and running regex queries all the time is not very convenient but very time consuming.īelow I outline an approach how to achieve the same result with using a GPO (Group Policy Object.) The GPO will be scoped to a computer group so that you may enforce TLS 1.2 simply by adding a computer account to a group and rebooting the computer. For VMware, Hyper-V or XenServer hosted computers you can still initiate a remote session in console mode and change the settings back, but for Azure hosted VMs (Virtual Machines) it is more difficult as there is no console, so you would have to revert the TLS settings using remote PowerShell or CLI. However, if you make this change logging on to the computer remotely via RDP and the new TLS settings negatively impact your ability to RDP back to the computer, it may be difficult to revert those changes. Microsoft provides recommendation on TLS enforcement using Registry settings in the following article: TLS, DTLS, and SSL protocol settings This document outlines how to set up a GPO (Group Policy Object) to disable TLS 1.0 and enforce TLS 1.2 based on an AD (Active Directory) security group. It is recommended to use a more recent and secure version of TLS, such as TLS 1.2 or TLS 1.3, for all secure communications. ![]() Industry security standards organizations, such as PCI Security Standards Council, have required that all entities handling credit card information discontinue the use of TLS 1.0 as of June 30, 2018. ![]() Most major browsers and operating systems stopped supporting TLS 1.0 as of around 2020. TLS 1.0 has been deprecated for a while now, and its use is discouraged due to security vulnerabilities. ![]()
