Personal SIEM Instance

https://github.com/anubis619/siem_project
This project is the implementation and day-to-day use of my own SIEM tool inside my home lab to monitor my infrastructure and gain exposure to using an SIEM tool. I opted for Wazuh because of the cost; it is open-source and can store data for a longer period. I looked at other tools like SumoLogic, but the free tier has a 7-day retention period.

While other tools like SumoLogic, Splunk, and Sentinel are a few of the most used SIEM tools by companies, they tend to come with a high price for personal use.
