No previous permissions are preserved. That's your job. You're warned! You probably want `Grant-ServicePermission` or `Revoke-ServicePermission` instead. .LINK Get-ServicePermission .LINK Grant-ServicePermission .LINK Revoke-ServicePermission .EXAMPLE Set-ServiceDacl -Name 'Hyperdrive' -Dacl $dacl Replaces the DACL on the `Hyperdrive` service. Yikes! Sounds like something the Empire would do, though. #> [CmdletBinding(SupportsShouldProcess=$true)] param( [Parameter(Mandatory=$true)] [string] # The service whose DACL to replace. $Name, [Parameter(Mandatory=$true)] [Security.AccessControl.DiscretionaryAcl] # The service's new DACL. $Dacl ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -Session $ExecutionContext.SessionState $rawSD = Get-ServiceSecurityDescriptor -Name $Name $daclBytes = New-Object byte[] $Dacl.BinaryLength $Dacl.GetBinaryForm($daclBytes, 0); $rawSD.DiscretionaryAcl = New-Object Security.AccessControl.RawAcl $daclBytes,0 $sdBytes = New-Object byte[] $rawSD.BinaryLength $rawSD.GetBinaryForm($sdBytes, 0); if( $pscmdlet.ShouldProcess( ("{0} service DACL" -f $Name), "set" ) ) { [Carbon.Service.ServiceSecurity]::SetServiceSecurityDescriptor( $Name, $sdBytes ) } } |
