About this course
Understand how activity becomes security evidence and how meaning, time, identity, lineage, and health can be preserved or lost along the way. 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: How Activity Becomes a Record
See why a log record is a constructed view of activity rather than the activity itself.
Module 2: Time and Identity Give Events Their Relationships
Learn to relate events without inventing order or merging different subjects.
Module 3: Preserve Meaning While Data Changes Shape
Use common schemas without losing source fidelity, and operate telemetry as a dependency rather than a passive feed.
