Episode 23 — Classify data properly to drive the right privacy safeguards (Domain 2C-3 Data Classification)

This episode focuses on data classification as a decision tool that drives safeguards, access rules, retention, and sharing controls, not as a label exercise. You’ll learn how privacy classification differs from security-only classification by emphasizing identifiability, sensitivity, context, and potential harm, including re-identification and inference risk. We’ll cover practical classification methods that work across structured and unstructured data, and we’ll walk through examples like telemetry, chat logs, biometrics, health-related attributes, and financial signals to show how classification choices change control requirements. You’ll also practice exam-style situations where data is partially masked, tokenized, or aggregated, and you’ll learn how to choose answers that prioritize defensible criteria, consistent application, and measurable control enforcement.
