About this course

Learn how detection engineers move from an uncertain security concern to a bounded, testable claim without confusing data, framework mappings, or alerts with proof. 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: Evidence Is Not the Same as a Conclusion

Separate observed activity from interpretation, alerting, incident judgment, and response authority.

Module 2: Turn a Threat Concern into a Detection Hypothesis

Decompose behavior, identify invariants, and write a hypothesis that evidence can support or contradict.

Module 3: Write Requirements and Make Honest Coverage Claims

Define the consumer, evidence, timing, tests, and limits before claiming that a behavior is covered.
