Quick ProTip: Negotiate TLS Connections In Powershell With A Minimum TLS Version Requirement

1. Проверить текущие настройки поддерживаемых протоколов

[Net.ServicePointManager]::SecurityProtocol

Возможные варианты

[enum]::GetNames([Net.SecurityProtocolType])
[System.Net.ServicePointManager]::SecurityProtocol = 'Tls11, Tls12'

В моей системе Windows 10 с Powershell v5.1 это значение возвращает значение SystemDefault. Это значение было введено в .NET 4.7 (предыдущие версии .NET не возвращают значения по умолчанию, только перечисляемый список) и позволяет вашей операционной системе выбирать протокол, с которым лучше всего согласовывать соединение. При обычных обстоятельствах это лучший вариант для использования, поскольку значения по умолчанию меняются в зависимости от текущей ситуации с безопасностью.

Однако SystemDefault может быть слишком мягким в объявлении доступных протоколов. SSLv3?! - Да, нет, спасибо.

Мы видим, что по умолчанию

Set strong cryptography on 64 bit .Net Framework (version 4 and above)

Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

set strong cryptography on 32 bit .Net Framework (version 4 and above)

Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

3. Перезапустить Powershell и проверить настройки поддерживаемых протоколов [Net.ServicePointManager]::SecurityProtocol

Open Powershell (As Admin)

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

$Computers = @(
    "10.0.10.10",
    "10.0.10.11",
    "10.0.10.12"
)
 
 
$Timeout = 3000
$Ping = New-Object System.Net.NetworkInformation.Ping
 
$Results = Foreach ($Computer in $Computers) {
    $Response = $Ping.Send($Computer,$Timeout)
    [PSCustomObject]@{
        TimeStamp = Get-Date
        Address = $Computer
        Status = $Response.Status
        RTT = $Response.RoundtripTime
    }
}
<# Here's examples of what the results would look like if you wanted to do anything with that info
TimeStamp            Address          Status RTT

Foreach ($Result in $Results) {

        Write-Output "$($Result.Address) NOK"
        $OK = 0
    }
