About this course

Learn how Sigma expresses portable intent and how detection-as-code turns that intent into reviewed, tested, traceable runtime content. The course is written for one reader and develops its ideas through continuous explanation, realistic thought experiments, and explicit distinctions between fact, assessment, and uncertainty.

What you'll learn

  • Reason from a security concern to evidence and a bounded analytical claim.
  • Explain assumptions, tradeoffs, and limitations in plain language.

Before you begin

You will get more from this course if these foundations are already familiar.

  • Detection Engineering: From Telemetry to Tuned Detections — You should understand the basic detection lifecycle and common telemetry sources.

Course content

Module 1: Portable Rules Preserve Intent, Not Identical Behavior

Understand rule structure and portability without assuming that one document behaves identically everywhere.

Module 2: Correlation and Filters Add State and Local Policy

Understand Sigma 2.1 correlation forms and reusable filters together with their timing and tuning assumptions.

Module 3: Detection-as-Code Is a Chain of Evidence

Use versioning, tests, provenance, staged deployment, and retirement to keep content trustworthy through change.
