PowerShell Module

edit

The PowerShell module processes event log records from the Microsoft-Windows-PowerShell/Operational and Windows PowerShell logs.

The module has transformations for the following event IDs:

  • 400 - Engine state is changed from None to Available.
  • 403 - Engine state is changed from Available to Stopped.
  • 600 - A Provider is Started.
  • 800 - Pipeline executed.
  • 4103 - Module logging.
  • 4104 - Script block logging.
  • 4105 - Command started.
  • 4106 - Command completed.

Configuration

edit

By default, module and script block logging (event ID’s 410x) are disabled, to enable them you can do so through "Windows Powershell" GPO settings and set "Turn on Module Logging" and "Turn on PowerShell Script Block Logging" to enabled.

Alternatively they can be enabled setting the following registry values:

HKCU/HKLM\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ModuleLogging: EnableModuleLogging = 1
HKCU/HKLM\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ModuleLogging \ModuleNames: * = *
HKCU/HKLM\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ScriptBlockLogging: EnableScriptBlockLogging = 1
HKCU/HKLM\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ScriptBlockLogging: EnableScriptBlockInvocationLogging = 1
