# Windows Event Log

## Dump Logfile

Windows Event Logfiles can be dumped via

```sh
evtx_dump $EVENT_LOG > event.log
evtx_dump -o json $EVENT_LOG > event.log
```

## Query Windows Events

One method is to use the GUI Tool `Event Viewer`, another method is to use Powershell.

Use `Win-Event` to filter categories like Security or System (same categories
like in `Event Viewer`) and Event IDs throught the following line.

```sh
Get-WinEvent -FilterHashTable @{LogName='<Category>';ID='<Event IDs>'} | fl
```
