Episode 56 — Classify Data That Matters: PII, PHI, Sensitivity Levels, and Handling Rules
This episode teaches data classification as the foundation for nearly every downstream control, because DS0-001 questions often assume you can decide how data should be handled based on its sensitivity and regulatory exposure. You’ll learn practical definitions for PII and PHI, and you’ll discuss how classification extends beyond those labels into sensitivity levels such as public, internal, confidential, and restricted, each with different access rules and protection expectations. We’ll cover classification workflows, including how to identify sensitive fields in structured tables and semi-structured documents, how to tag datasets and columns, and how to keep classifications current when schemas evolve or new sources are ingested. Handling rules will include how classification drives encryption decisions, masking requirements, auditing scope, retention schedules, and sharing restrictions, including what must change when data moves into analytics systems, test environments, or third-party platforms. Scenario examples will include determining whether a dataset used for fraud detection contains regulated identifiers, preventing accidental exposure through a view that joins sensitive and non-sensitive tables, and resolving disagreements between teams about whether a field is truly identifying when combined with other attributes. By the end, you should be able to classify data consistently and explain how that classification translates into specific controls that are defensible on an exam and in a real audit.
