 EvtxECmd - this tool will help us to convert event logs into csv format. Later we can use timeline analysis tool to analysis the csv data more efficiently.  This tool also help us to convert logs into json format.  Download the tool first. https://ericzimmerman.github.io/#!index.md Command : evtxecmd --sync evtxecmd -f E:\C\Windows\System32\winevt\logs\Security.evtx --csv g:\Labs\event-logs --csvf security.csv evtxecmd -f "e:\C\Windows\System32\winevt\logs\Microsoft-Windows-TaskScheduler%40Operational.evtx" --csv G:\Labs\event-logs --csvf taskscheduler.csv Windows have so many event logs and so many event id's. Not all the event id's are important. Of course you can use your own but Mark Hallman created a script that will parse all the important event id's that is discussed in SANS FOR508 course. You can use mark hallman's Process-EventLogs.ps1 tool that will parse important event id's from bulk event logs leveraging evtxecmd tool.  https://github.com/ma...
