Security Center components use cryptographic protocols to communicate securely. All versions of Secure Sockets Layer (SSL), and early versions of Transport Layer Security (TLS) protocol are vulnerable, so we recommend disabling these protocols in Windows.

Best Practice: From 2019, disable SSL 3.0 and TLS 1.0. Only use TLS 1.1 if it is still required by other programs in your network.

Some vulnerable protocols might be disabled by default in your version of Windows. For more information on SSL and TLS support, see Protocols in TLS/SSL (Schannel SSP).

For instructions on how to disable cryptographic protocols in Windows, see "SSL 3.0", "TLS 1.0", and "TLS 1.1" in Transport Layer Security (TLS) registry settings.
