Episode 7 — Trace Every Cardholder Data Flow Without Guesswork.
This episode teaches you how to validate cardholder data flows as a working artifact for scoping, testing, and evidence, not as a diagram that exists only to satisfy a requirement. You’ll learn what a defensible data flow actually includes, such as entry points, processing steps, storage locations, transmission paths, and the people and systems that touch the data along the way. We define common terms that show up in exam questions, including “account data,” “cardholder data,” “sensitive authentication data,” and the risk implications of mixing them. You’ll also learn how to test a data flow for completeness by reconciling it with network paths, application architecture, logs, and operational procedures, and how to resolve contradictions when stakeholders disagree about what happens in production. Real-world examples include e-commerce redirects, payment gateways, call-center workflows, file exports, and third-party integrations that can introduce hidden storage or transmission.
