Summary:

If you can type this, Findthis ~ With this EventLog Name(Not required) ~ EventID(Not required) into a text file (Searchs.txt) you can find the logs you want from a windows machine and send just those to your SIEM.

Why SWELF and how is it diffrent from anything out there? Well, are you having the to many log issue? Or maybe just cant        
find what you want from a log forwarder? Want to quickly get the logs you want from local evtx files or eventlog service and 
then get them in the order they where made? Maybe the other log forwarders are just too complicated and you want something  
simple that can do it all? SWELF might be able to help you. You tell SWELF the the key words and/or Event Log Name and/or the 
event ID and it will find it for you. You can event tell it things like the minimum number of characters in log, or the 
maximum length of the command-line arguments, or the length of the log itself, then the SWELF app will send just that log to 
your Log Collection location from a windows machine in a variety of formats. SWELF is designed to be as small,lightweight, and 
windows native as possible with very low requirements and setup and still be a powerful and useful tool. SWELF is designed to 
put you back in control of your log data and your log forwarder as much as possible. Also, an interesting case has come up 
recently, that red teamers could use this to help simulate a SIEM on a VM for testing on an endpoint. SWELF is designed to be

The details:

Now almost in full release.

SWELF is designed to be a simple enough for almost anyone to use for windows event log forwarding application with some speedy IR capabilities. As a forwarder the agent will 1st search your logs for what you want, then forward just those logs. Since SWELF is early release software this means there may be bugs that exist.

But this also means im taking almost any feature request (even if you dont code), deisgn recommendations, and basically any input you think is relavent. I will take it in the form of Twitter (https://twitter.com/Ceramicskate0?lang=en) or as Issue (Feature) request here on Github.

This app is a mainly a log forwarder with the ability to search, forward, and run your plugins. This means that you can tell your log forwarding agent (SWELF) exactly what logs to forward and it wont forward the rest (This will help with that pesky "to many logs", "we cant send those logs its to much noise", or "the SIEM cant handle all the logs" issues with SIEMs and IT Departments). ;D

For example, you want powershell logs (dont lie to yourself every security person does, or at least you better). You know what you want them to have in the log, or what they should looks like, or how long they are, or some keyword, then SWELF will forward in order just those logs.
