Quickstart: Convert Group Policy into DSC

Applies To: Windows PowerShell 4.0, Windows PowerShell 5.0

You can generate a DSC configuration from a Group Policy or Azure Security Center baseline. The BaselineManagement module includes the following commands for accomplishing this task.

  • ConvertFrom-GPO - Converts Group Policies, stored as files. You can also specify a directory containing multiple policies that will be combined into one Configuration.
  • ConvertFrom-SCM - Converts Security Compliance Manager baselines, stored as .xml files.
  • ConvertFrom-ASC - Converts Azure Security Center baselines, stored as .json files.
  • Merge-GPOs - Converts Group Policies applied to a target computer.

The cmdlets listed above convert a baseline into a DSC .mof file. You can also choose to output a Configuration script (.ps1), that you can edit and recompile. The cmdlets detect compilation errors for missing resources, or duplicate resource blocks. Resource blocks that would cause compilation errors are commented out.

The following example converts a Microsoft Security Baseline into a DSC configuration script (.ps1) and .mof file.

Install-Module BaselineManagement
Import-Module BaselineManagement
ConvertFrom-GPO -Path '.\Windows 10 Version 1903 and Windows Server Version 1903 Security Baseline\GPOs\' -OutputConfigurationScript

After running the commands, you see two files in the default "Output" directory created under your current path.

Get-ChildItem -Path .\Output
    Directory:  C:\Temp

Each managed node will also need the following two modules:
