How to Enable TLS 1.3 on IIS Web Server with Windows Server 2022 for Enhanced Cloud Service Security?

Hello everyone,

I’m currently working on improving the security of my web applications hosted on IIS with Windows Server 2022. As we know, using TLS 1.3 can significantly enhance security, especially when dealing with sensitive data in a cloud service environment. I wanted to share my findings and seek any additional advice or tips from the community.

First, I’ve verified that my server is up to date with the latest Windows updates. I understand that TLS 1.3 is supported on Windows Server 2022, but enabling it requires a few specific configurations. Here’s the step-by-step process I followed:

  1. Registry Configuration: I opened the Registry Editor and navigated to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols. Here, I created a new key named TLS 1.3 and added two subkeys: Client and Server.
  2. Enabling the Protocol: Within the Client and Server keys, I created a DWORD value named Enabled and set it to 1. I also added a Disabled DWORD value and set it to 0.
  3. Restarting the Server: After making these changes, I restarted the server to apply the new settings.
  4. Verifying the Configuration: Finally, I used an online SSL checker to confirm that TLS 1.3 was enabled successfully.

I’m curious if anyone else has implemented TLS 1.3 on their IIS servers and if you faced any challenges. Additionally, I’d love to hear your thoughts on the impact of using TLS 1.3 for applications interacting with cloud services. Has it improved performance or security in your experience?

Thank you for any insights you can share! I’m looking forward to enhancing our server security together.
