In older Windows systems (Windows Server 2012 or earlier), TLS 1.2 must be enabled systemwide by setting "SchUseStrongCrypto". SystemDefaultTlsVersions is a configuration switch in .NET Framework (starting from 4.6) that allows the application to use the default TLS version supported by the underlying Windows operating system instead of hardcoding a specific TLS version (like TLS 1.2). Check Registry: Use regedit to review the following Windows registry keys: For 32-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\ For 64 bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\ HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\ 1. If the "SchUseStrongCrypto" value name does not exist, or is not a REG_DWORD type set to "1", this is a finding. 2. For .NET Framework >4.6, use the default TLS version supported by the underlying Windows operating system. If the "SystemDefaultTlsVersions" value name does not exist, or is not a REG_DWORD type set to "1", this is a finding. Note: The SchUseStrongCrypto setting allows .NET to use TLS 1.1 and TLS 1.2. The SystemDefaultTlsVersions setting allows .NET to use the OS configuration.

1. SchUseStrongCrypto enabled: Use regedit to access the following registry key. For 32-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\ For 64-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\ HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\ Modify or create the following Windows registry value: SchUseStrongCrypto. Set SchUseStrongCrypto to a REG_DWORD value of "1". 2. SystemDefaultTlsVersions enabled (.NET Framework >4.6): For 64-bit Windows, create a .reg file with the following content and apply it: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319] "SystemDefaultTlsVersions"=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319] "SystemDefaultTlsVersions"=dword:00000001 3. Restart the system for changes to take effect.
