A mid-sized organization generates logs from dozens of systems — firewalls, servers, applications, cloud services. No analyst can manually check all of it. SIEM aggregates that data into one place and applies rules to surface what actually matters.
Analysts write and refine queries against the aggregated log data, build detection rules, and investigate the alerts those rules generate. The SIEM doesn't replace judgment — it makes the raw material searchable enough for judgment to be possible.
A SIEM is only as good as its configuration. Poorly tuned rules generate alert fatigue — so much noise that real threats get missed in the flood. Tuning a SIEM well is itself a significant skill.
This article is the short version. The full program covers it hands-on, in labs, with a mentor reviewing your work.
