# Audit Powershell Scriptblock
## Setup

Some detection rules require enabling PowerShell Script Block Logging to record the content of processed script blocks in the Windows Event Log.
To collect these logs, use the [Windows Integration](https://www.elastic.co/docs/current/integrations/windows) and select the `Powershell Operational` channel on the integration setup page.

### Enable Audit Policy via Group Policy

To enable PowerShell Script Block logging across a group of servers using Active Directory Group Policies, administrators must enable the `Turn on PowerShell Script Block Logging` policy. Follow these steps to implement the logging policy:
```
Computer Configuration >
Administrative Templates >
Windows PowerShell >
Turn on PowerShell Script Block Logging (Enable)
```


### Enable Audit Policy via Registry

To configure the audit on servers that aren't domain joined, the EnableScriptBlockLogging registry key must be set to 1. Here is an example modification command:
```
reg add "hklm\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ScriptBlockLogging" /v EnableScriptBlockLogging /t REG_DWORD /d 1
```


## Event IDs

When this audit policy is enabled, the following event IDs may be generated in the `Microsoft-Windows-PowerShell/Operational` log:
- **4104**: Script block execution.
