Ensure TLS 1.1 is Disabled

TinggiLevel 1Otomatisiis

Deskripsi

The TLS 1.1 protocol is not considered cryptographically secure, therefore should be disabled. SCHANNEL\Protocols\TLS 1.1\Server and \Client must both have Enabled=0 and DisabledByDefault=1. Affects every SCHANNEL service; a reboot is required after changes. PowerShell 5.1; reads the registry (run elevated).
