After installing a cumalitive update on Exchange 2013 SSL3.0 is weer enabled.
With the following script you can disable SSL3.0
DisableSSL3.0.ps1:
$keyPathRoot = “HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols”;
$keyPath = $keyPathRoot + “\SSL 3.0\Server”;
if (!(Test-Path $keyPath))
{
New-Item -path $keyPathRoot”\SSL 3.0″ -ItemType key -Name “Server” -Force;
}
Set-ItemProperty -path $keyPath -name “Enabled” -value 0x0 -Type DWORD -Force;
Thnx Andy David for the tip
