## Overview

This repository is a teaching package for an undergraduate cybersecurity course, not a software runtime. The documented learner journey is to use the course overview and chapter materials to study foundational theory and security domains, then deepen understanding through guided experiments. The README describes these relationships and the experiment resources; no source excerpts were supplied, so the graph represents documented access and learning flow rather than internal software calls.
