If you do not explicit define the correct sourcetype, Splunk will display garbled characters after import EventLog evtx file. You will need to use the sourcetype preprocess-winevt. In other word, the nf should be deployed or defined on a windows machine in order to successfully import Event Log into Splunk.

Similarly, Splunk also use native Windows API to process the exported evtx file, you must use a Windows machine with Splunk installed (either Universal Forwarder or any full Splunk instance including All-in-one Splunk instance or Heavy forwarder instance) to process the evtx file.

In the view of Windows program design, you need to call Windows API and let Windows to complete the requested actions for you. To export evtx file, just open “Event Viewer”, and then right click to save evtx file. If you do this, you risk to corrupt the Windows Event Log evtx file. Therefore, you cannot directly edit or copy those evtx files for processing. I use Splunk just because there are some commands such as transaction, streamstats and eventstats which are difficult to replace with other tools, and we have some ready-to-use threat hunting query which we can speed-up our initial triage process.īy default, Windows EventLog evtx files are stored in C:\Windows\System32\winevt\Logs, and evtx files are protected by the Windows kernel. Of source, I am not trying to convince anyone to use Splunk during their incident response process. This way you might relatively easily get your logs and syslog is easy to receive but the events you get this way will be horribly mangled and not suitable for typical slplunk-side processing (meaning they will not be understandable by TA-windows).During my incident response engagement, I always need to import EventLog into Splunk for further analysis. The solution which can be used but honestly speaking should never even be considered is using a third party forwarder (typically a syslog one like kiwi, solarwinds or nxlog). Performance is not very good, you _must_ run the UF with domain account (which implies that it can only be used in domain environment) and there are often issues with permissions/privileges so it might be tricky to set up unless you have a very good windows admin team. WMI can be used to pull from remote computers but that's generally a last resort solution. Be aware of possible performance issues as you scale horizontally too far.

But it might create issues of scalability and windows admins might not be thrilled if you want to install third-party tools on domain controllers or other important servers.Īnother relatively well working idea is to use Windows Event Forwarding (easy to set up in a domain environment, can be also confuigured in domainless setup but then it gets complicated but still possible) and pull windows from a central eventlog collector. The easiest and most straightforward way is to install UF on a monitored server and pull events directly from local eventlog. There are several methods of collecting windows EventLogs. You can use WMI to pull EventLog from remote computer but you sitll have to install that windows splunk component which will be doing the pulling (UF or HF) somewhere.
