Earlier versions of Windows, such as Windows 7 or Windows Server 2012, don't enable TLS 1.1 or TLS 1.2 by default for secure communications using WinHTTP. For these earlier versions of Windows, install Update 3140245 to enable the registry value below, which can be set to add TLS 1.1 and TLS 1.2 to the default secure protocols list for WinHTTP. With the patch installed, create the following registry values:

Enable Opportunistic TLS in IIS SMTP Service - Tutorial¶. IIS SMTP Service is a Windows built-in SMTP service. It is widely used to relay email on Windows Server. TLS is a cryptographic protocol designed to provide communications security over a computer network. Most SMTP servers support TLS encryption to create a secure connection for email transmission. Sep 03, 2019 · Transport Layer Security (TLS), the successor to Secure Sockets Layer (SSL) which has been deprecated now, is a cryptographic protocol designed to provide communications security over a computer network. In other words, TLS protocol aims mainly to provide privacy and data integrity between two or more communicating computer applications. The code below is a complete implementation of a minimal TLS server. The first thing we do is initialise openssl in the init_openssl () function by loading the strings used for error messages, and setting up the algorithms needed for TLS. We then create an SSL_CTX or SSL context. Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing , email , instant messaging , and voice over IP (VoIP). When enabling TLS 1.2 for your Configuration Manager environment, start with enabling TLS 1.2 for the clients first. Then, enable TLS 1.2 on the site servers and remote site systems second. Finally, test client to site system communications before potentially disabling the older protocols on the server side.

When your server is up-to-date with all security patches offered by Microsoft, then you probably already have TLS 1.2 installed. In this case, you can jump to the next section and activate it. Should you not have all patches installed, you can manually download KB4019276 from the Microsoft Update Catalog .

Jun 24, 2020 · If the customer sets the agents to use TLS 1.2 to communicate with the server, refer to the Windows Server 2008 R2 section of KB 1117987 to install Windows Update. To resolve the issue: After the agent has installed Windows Update and the EasyFix, it will add the registry key "DefaultSecureProtocols"=dword:00000a00
