I’m currently a sysadmin for a small university and I’m trying to pivot into a more cybersecurity focused role. Our administration is security conscious but we’re understaffed and underfunded. I’m looking to implement an SIEM but it would need to be free/open source. Also, I’ll have to bring it up in a test lab in my free time before I can convince them to implement it so I’m really looking for the most straightforward option with the best documentation/support community. Thanks for your suggestions!
