SIEM Operations — The SIEM Funnel

A hands-on mid-level course that runs the daily operation of a SIEM - onboarding sources, keeping parsing and normalization correct, enriching events with context, correlating signal into meaningful alerts, and tuning and retaining data without losing detection value. Work the SIEM funnel - eight stages raw logs pass through: Onboard, Parse, Normalize, Enrich, Correlate, Alert, Tune, and Retain - with real source coverage mapping, parser and timestamp fixes, schema mapping, enrichment pipelines, risk-based correlation, alert routing and SLAs, precision-tracked tuning, and tiered, immutable retention. Four hands-on activities in every lesson.

What you'll learn

• Onboard log sources against a real coverage map and keep parsing, timestamps, and schema mapping correct.
• Enrich events with asset, identity, geo, and threat-intel context automatically before they reach correlation.
• Write correlation rules that combine signal across identity, endpoint, and network with risk-based alerting.
• Keep alerts high-quality and routed, tune false positives narrowly, and retain data by real need, cost, and integrity.
