Transport Layer Security (TLS) are cryptographic protocols designed to provide communications security over a computer network, typically between a website and a browser.

TLS 1.0 and its deprecated predecessor, SSL are vulnerable to some well-known security issues such as POODLE and BEAST attacks. According to NIST, these vulnerabilities cannot be fixed or patched, therefore all companies, especially banks and other financial institutions who are notoriously slow in upgrading theirs systems, need to upgrade to a secure alternative as soon as possible, and disable any fallback to both SSL and the older TLS 1.0.

As of 30 June 2018, SSL and TLS 1.0 should be disabled and more secure encryption protocol such as TLS 1.2 (or at the minimum TLS 1.1) is required to meet the PCI Data Security Standard (PCI DSS) for safeguarding payment data.

The IRS requires TLS 1.1 TLS 1.2 in order to access their site any longer. I went and googled 'how to' however; the instructions for Google Chrome don't work for my system because under Advance Settings I don't have 'Network'. So I can't change my proxy settings that way. In M-84, Chrome will show a full page interstitial warning on sites that do not support TLS 1.2 or higher. TLS 1.2 was published ten years ago to address weaknesses in TLS 1.0 and 1.1 and has enjoyed wide adoption since then. These old versions of TLS rely on MD5 and SHA-1, both now broken, and contain other flaws.

The next question then how on do we enable TLS 1.2 on Windows Servers? Especially on older servers such as Windows Server 2008 as many companies are not on the latest and greatest operating systems?

This post will address what to look for and how to enable TLS 1.2 as the default protocol for Windows Server 2012 R2 or older.

IMPORTANT: As always and it’s worth repeating, you need to backup your current registry settings before attempting any of these changes on your servers.

Enable TLS 1.2 on Windows Servers 2008 SP2 or later

The blanket statement to enable your TLS 1.2 on your server from Windows Server 2008 SP2 or later. Microsoft provided an update to add support for TLS 1.1 and TLS 1.2 for Windows Server 2008, but it requires Windows Server 2008 SP2 installed.

So just to state the obvious, TLS 1.1 and TLS 1.2 are not supported for 32-bit Windows Server 2008 SP1.

  1. Launch regedit.exe.

  2. In registry, go to:

  3. Create a new DWORD entry with a name TLS 1.2 and create another subkey Client and Server.

  4. Under the subkey Server, create another DWORD Enabled with a value of 1.

  5. Still under the subkey Server, create a DWORD DisabledByDefault with a value of 0.

  6. You must create a subkey DisabledByDefault entry in the appropriate subkey (Client, Server) and set the DWORD value to 0 since this entry is set to 1 by default.

  7. Reboot the server and test.

Enable TLS 1.2 on .NET Framework 3.5 (including 2.0)

.NET Framework 3.5 or earlier did not originally provide support of applications to use TLS System Default Versions as a cryptographic protocol. However, for Windows Server 2012 R2, check if KB3154520 is installed (or KB3154519 for Windows Server 2012; KB3154518 for Windows Server 2008 R2; KB3154517 for Windows Server 2008 SP2).

How to check the KB updates

  1. Right-click on the Windows button and select Programs and Features.

  2. On Programs and Features window, click onthe View installed updates on the left pane.

  3. You will see a list of the updates that you can narrow down or do a very specific search by using the Search Installed Updates box. You can type in the KB number (i.e., “KB3154520”).

  4. If the corresponding KB is already installed, we just need to enable it via registry change. Otherwise, you need to install the patch from either of the links for Windows Server 2012 R2 (or use the same corresponding links above for earlier versions of Windows Server).

Registry Change

Enable Tls 1.2 On Chrome For Macsportfasr Pc

  1. Launch regedit.exe.

  2. Go to:

  3. Create a new entry SystemDefaultTlsVersions with a DWORD value set to 1.

  4. Create a new entry SchUseStrongCrypto with a DWORD value set to 1.

  5. Go to:

  6. Create a new entry SystemDefaultTlsVersions with a DWORD value set to 1.

  7. Create a new entry SchUseStrongCrypto with a DWORD value set to 1.

  8. For 64-bit OS, the same changes also needed for the following locations:

  9. Create a new entry SystemDefaultTlsVersions with a DWORD value set to 1.

  10. Create a new entry SchUseStrongCrypto with a DWORD value set to 1.

  11. Go to:

  12. Create a new entry SystemDefaultTlsVersions with a DWORD value set to 1.

  13. Create a new entry SchUseStrongCrypto with a DWORD value set to 1.

  14. Test.

Enable TLS 1.2 as default for WinHTTP

This may be applicable for any Classic ASP or VB6 applications that use WinHTTP. Prior to Windows 10 and Windows Server 2016, TLS 1.1 or 1.2 is not enabled by default for client-server communications through WinHTTP.

To set TLS 1.2 by default, do the following:

  1. Create a registry entry DefaultSecureProtocols on the following location:

  2. Set the DWORD value to 800 for TLS 1.2.

  3. For 64-bit OS, repeat step 1 and 2 on the following location:

  4. Reboot the server and test.

Windows 10 and Windows Server 2016 support TLS 1.2 for client-server communications by using WinHTTP.

Enable Tls 1.2 On Chrome For Macsportfasr Windows 8.1

Description
If this policy is not configured then Google Chrome uses a default minimum version, which is TLS 1.0. Otherwise, it may be set to one of the following values: 'tls1', 'tls1.1' or 'tls1.2'.When set, Google Chrome will not use SSL/TLS versions less than the specified version. An unrecognized value will be ignored.'tls1' = TLS 1.0'tls1.1' = TLS 1.1'tls1.2' = TLS 1.2
