#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Enable-DbaForceNetworkEncryption { <# .SYNOPSIS Enables Force Encryption for a SQL Server instance. .DESCRIPTION Enables Force Encryption for a SQL Server instance. Note that this requires access to the Windows Server, not the SQL instance itself. This setting is found in Configuration Manager. .PARAMETER SqlInstance The target SQL Server. .PARAMETER Credential Allows you to login to the computer (not SQL Server instance) using alternative Windows credentials .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .EXAMPLE Enable-DbaForceNetworkEncryption Enables Force Encryption on the default (MSSQLSERVER) instance on localhost. Requires (and checks for) RunAs admin. .EXAMPLE Enable-DbaForceNetworkEncryption -SqlInstance sql01\SQL2008R2SP2 Enables Force Network Encryption for the SQL2008R2SP2 on sql01. Uses Windows Credentials to both connect and modify the registry. .EXAMPLE Enable-DbaForceNetworkEncryption -SqlInstance sql01\SQL2008R2SP2 -WhatIf Shows what would happen if the command were executed. .NOTES Tags: Certificate Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = "Low", DefaultParameterSetName = 'Default')] param ( [Parameter(ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer", "ComputerName")] [DbaInstanceParameter[]] $SqlInstance = $env:COMPUTERNAME, [PSCredential]$Credential, [switch][Alias('Silent')]$EnableException ) process { foreach ($instance in $sqlinstance) { Write-Message -Level VeryVerbose -Message "Processing $instance." -Target $instance $null = Test-ElevationRequirement -ComputerName $instance -Continue Write-Message -Level Verbose -Message "Resolving hostname." $resolved = $null $resolved = Resolve-DbaNetworkName -ComputerName $instance -Turbo if ($null -eq $resolved) { Stop-Function -Message "Can't resolve $instance." -Target $instance -Continue -Category InvalidArgument } Write-Message -Level Output -Message "Connecting to SQL WMI on $($instance.ComputerName)." try { $sqlwmi = Invoke-ManagedComputerCommand -ComputerName $resolved.FQDN -ScriptBlock { $wmi.Services } -Credential $Credential -ErrorAction Stop | Where-Object DisplayName -eq "SQL Server ($($instance.InstanceName))" } catch { Stop-Function -Message "Failed to access $instance" -Target $instance -Continue -ErrorRecord $_ } $regroot = ($sqlwmi.AdvancedProperties | Where-Object Name -eq REGROOT).Value $vsname = ($sqlwmi.AdvancedProperties | Where-Object Name -eq VSNAME).Value $instancename = $sqlwmi.DisplayName.Replace('SQL Server (', '').Replace(')', '') $serviceaccount = $sqlwmi.ServiceAccount if ([System.String]::IsNullOrEmpty($regroot)) { $regroot = $sqlwmi.AdvancedProperties | Where-Object { $_ -match 'REGROOT' } $vsname = $sqlwmi.AdvancedProperties | Where-Object { $_ -match 'VSNAME' } if (![System.String]::IsNullOrEmpty($regroot)) { $regroot = ($regroot -Split 'Value\=')[1] $vsname = ($vsname -Split 'Value\=')[1] } else { Stop-Function -Message "Can't find instance $vsname on $instance." -Continue -Category ObjectNotFound -Target $instance } } if ([System.String]::IsNullOrEmpty($vsname)) { $vsname = $instance } Write-Message -Level Output -Message "Regroot: $regroot" -Target $instance Write-Message -Level Output -Message "ServiceAcct: $serviceaccount" -Target $instance Write-Message -Level Output -Message "InstanceName: $instancename" -Target $instance Write-Message -Level Output -Message "VSNAME: $vsname" -Target $instance $scriptblock = { $regpath = "Registry::HKEY_LOCAL_MACHINE\$($args[0])\MSSQLServer\SuperSocketNetLib" $cert = (Get-ItemProperty -Path $regpath -Name Certificate).Certificate $oldvalue = (Get-ItemProperty -Path $regpath -Name ForceEncryption).ForceEncryption Set-ItemProperty -Path $regpath -Name ForceEncryption -Value $true $forceencryption = (Get-ItemProperty -Path $regpath -Name ForceEncryption).ForceEncryption [pscustomobject]@{ ComputerName = $env:COMPUTERNAME InstanceName = $args[2] SqlInstance = $args[1] ForceEncryption = ($forceencryption -eq $true) CertificateThumbprint = $cert } } if ($PScmdlet.ShouldProcess("local", "Connecting to $instance to modify the ForceEncryption value in $regroot for $($instance.InstanceName)")) { try { Invoke-Command2 -ComputerName $resolved.fqdn -Credential $Credential -ArgumentList $regroot, $vsname, $instancename -ScriptBlock $scriptblock -ErrorAction Stop | Select-Object -Property * -ExcludeProperty PSComputerName, RunspaceId, PSShowComputerName Write-Message -Level Critical -Message "Force encryption was successfully set on $($resolved.fqdn) for the $instancename instance.
