Migrating from TLS 1.0 to TLS 2.0

The Payment Card Industry has mandated that all PCI customers must migrate from SSL and TLS 1.0 to be considered compliant by June 30th 2018.  I want to migrate from TLS 1.0 and make TLS 1.1 and TLS 1.2 available for use.  I know that you can enable and disable both within the registry and in the "Internet Options Advanced Tab. On a Windows server 2008R2  through Windows 2012R2  where can I find the configuration for TLS 1.1 or 1.2 to be used whether an application, executable, or even the website? I have looked throughout IIS and cannot figure this out. Thanks in advance for any help available.

Have a look at this:


Payment Card Industry (PCI) requires TLS 1.1 or TLS 1.2 for compliance.

https://support.microsoft.com/en-ca/help/3140245/update-to-enable-tls-1-1-and-tls-1-2-as-a-default-secure-protocols-in

The DefaultSecureProtocols registry entry can be added in the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp
On x64-based computers, DefaultSecureProtocols must also be added to the Wow6432Node path:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp
The registry value is a DWORD bitmap. The value to use is determined by adding the values corresponding to the protocols desired.

DefaultSecureProtocols Value      Protocol enabled
0x00000008      Enable SSL 2.0 by default
0x00000020      Enable SSL 3.0 by default
0x00000080      Enable TLS 1.0 by default
0x00000200      Enable TLS 1.1 by default
0x00000800      Enable TLS 1.2 by default
For example:

The administrator wants to override the default values for WINHTTP_OPTION_SECURE_PROTOCOLS to specify TLS 1.1 and TLS 1.2.

Take the value for TLS 1.1 (0x00000200) and the value for TLS 1.2 (0x00000800) then add them together in calculator (in programmer mode), the resulting registry value would be 0x00000A00.

On Windows 2012 R2 the registry key you are after is here

HKey_Local_Machine\System\CurrentControlSet\Control\SecurityProviders \SCHANNEL\Protocols

and I believe this is the answer for 2008

I agree, just run this script:

It solves two vulnerabilities of that payment industry.
