Open source SIEM is where security careers get real. You can read about threat detection all day, but until you've deployed a SIEM, fed it logs, and caught a simulated attack, it's just theory. This category is built around that kind of hands-on security work, starting with Wazuh, the most widely used open source SIEM.
Our Wazuh SIEM workbook puts you in the analyst's seat. You stand up the platform, connect agents, tune rules, and run real lab scenarios: brute-force attempts, file-integrity changes, malware indicators, and compliance checks. Each lab gives you the goal, the steps, and a way to confirm the alert fired the way it should.
Two reasons. First, they're free, so you can build a full security lab at home without a licence. Second, employers actually run them. Wazuh, the Elastic Stack, and tools like them sit in real security operations centres every day. Learn them hands-on and you show up to interviews with skills a team can use on day one, not a certificate with nothing behind it.
This ties straight into the certs that matter for a SOC role. If you're aiming at a blue-team job, our CySA+ certification guide shows where SIEM skills fit, and our Security+ practice test covers the fundamentals you'll build on here.
Log collection and analysis, alert tuning, threat detection, incident triage, and compliance reporting. You'll wire up agents, write and adjust detection rules, and read the dashboard the way a working analyst does. By the end you'll know not just what a SIEM is, but how to run one when alerts are firing and the clock is ticking.
The point of every lab is a real outcome, not a checkbox. You trigger an attack, watch the wrong rule stay quiet, fix it, and see the alert land. That loop, break it then fix it, is what turns a nervous beginner into someone a SOC can trust with a live console. Tools change over the years, but the muscle of reading logs and chasing an alert to its source never goes out of date.
Aspiring SOC analysts, blue-team learners, sysadmins adding security to their skill set, and students who want a home lab that mirrors a real security team. If you learn by doing rather than watching, this is your track.
All you need is a Linux VM and a bit of RAM. Wazuh is free to download and runs happily on a modest home setup or a small cloud instance. We flag the resource requirements up front, so you can size your lab before you start. Spin it up, generate some events, and watch the alerts roll in.
Pick the workbook below, deploy your SIEM, and run the first detection lab today. Security skills stick when you've caught the alert yourself. Build it, test it, tune it. That's how you go from curious to hire-ready.
