通过 PowerShell 脚本启用 TLS 和禁用 SSL

Question

我希望在启用和执行 TLS 1.1 和 1.2 的同时自动禁用 SSL 协议 2 和 3 以及禁用 TLS 1.0。我根据我阅读的一些博客创建了一个 PowerShell 脚本，但是，我不喜欢我的脚本的外观。在规模和最佳实践方面，我喜欢以正确的方式构建脚本。我什至不知道如何开始，但我认为有更好的方法来写这个。

我已经很好地运行了脚本。完美运行。

function disable-ssl-2.0 {
    New-Item ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Server’ -Force
    New-ItemProperty -Path ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Server’ -Name Enabled -Value 0 –PropertyType DWORD
    Write-Host "Disabling SSLv2"
}
function disable-ssl-3.0 {
    New-Item ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Server’ -Force
    New-ItemProperty -Path ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Server’ -Name Enabled -Value 0 –PropertyType DWORD
    Write-Host "Disabling SSLv3"
}
function disable-tls-1.0 {
    New-Item “HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\PROTOCOLS” –Name “TLS 1.0”
    New-Item “HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\PROTOCOLS\TLS 1.0” –Name SERVER
    New-ItemProperty “HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\PROTOCOLS\TLS 1.0\SERVER” –Name Enabled –Value 0 –Type DWORD
    Write-Host "Disabling TLSv1.0"

function enable-tls-1.1 {
    New-Item ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Server’ -Force
    New-Item ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client’ -Force
    New-ItemProperty -Path ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Server’ -Name ‘Enabled’ -Value ‘0xffffffff’ –PropertyType DWORD

    Write-Host "Enabling TLSv1.1"
}
function enable-tls-1.2 {
    New-Item ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server’ -Force
    New-Item ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client’ -Force
    New-ItemProperty -Path ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server’ -Name ‘Enabled’ -Value ‘0xffffffff’ –PropertyType DWORD
    New-ItemProperty -Path ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server’ -Name ‘DisabledByDefault’ -Value 0 –PropertyType DWORD
    New-ItemProperty -Path ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client’ -Name ‘Enabled’ -Value 1 –PropertyType DWORD
    New-ItemProperty -Path ‘HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client’ -Name ‘DisabledByDefault’ -Value 0 –PropertyType DWORD
    Write-Host "Enabling TLSv1.2"
}

disable-ssl-2.0
disable-ssl-3.0
disable-tls-1.0
enable-tls-1.1
enable-tls-1.2

也许我应该通过分配变量来压缩注册表命令？只是不知道如何让这个脚本更专业。

Answer 1

这没有回答格式问题，但我为那些对更精细的注册表设置感兴趣的人添加了脚本，以删除旧的加密。
