IMF Tune v8 to support TLS 1.2

The Windows platform is currently in the process of deprecating the Transport Layer Security (TLS) 1.0 protocol. This is being replaced by the more secure TLS 1.2 protocol version.

This transition is relevant to the IMF Tune Quarantine functionality because of its reliance on an MS SQL Server database backend. Access to MS SQL is secured via TLS.

IMF Tune v7.x and earlier rely on database drivers that require TLS 1.0. Thus disabling this protocol causes them to fail.

IMF Tune v8 is being updated to work with SQL database drivers that support TLS 1.2

Windows Server 2019 Disables TLS 1.0

On Windows Server 2019, TLS 1.0 is disabled by default. This means the IMF Tune v7.x Quarantine components won't work unless this protocol is re-enabled manually.

Enablement of TLS 1.0 can be configured at the registry by switching the Client/Server Enabled value to 1:

HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client
"Enabled"=dword:00000000
"DisabledByDefault"=dword:00000001

HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Server
"Enabled"=dword:00000000
"DisabledByDefault"=dword:00000001

Note: IMF Tune v7.x has not been tested on Windows Server 2019. We do not recommend re-enabling the less secure TLS 1.0 protocol which may degrade the overall server security. We recommend upgrading to the upcoming IMF Tune v8 release that has been updated to work with TLS 1.2 and tested to run on Windows 2019.
