Episode 31 — Validate E-Commerce and Web Payments Without Surprises.
This episode focuses on the e-commerce paths that create the most confusion on the QSA exam and in real assessments, because small design choices can drastically change scope, data exposure, and control responsibilities. You’ll learn how to distinguish common models such as fully outsourced payment pages, embedded iFrames, direct post methods, hosted fields, and merchant-hosted checkout flows, and how each model affects where cardholder data is transmitted or processed. We define what a QSA must confirm when a business claims “we never touch PAN,” including testing for hidden storage in logs, analytics tools, error traces, and customer support exports, plus validating that redirects and scripts do not reintroduce data handling into the merchant environment. Practical troubleshooting includes reconciling diagrams with packet captures, reviewing application configurations, and confirming third-party responsibilities and attestations. The outcome is a repeatable approach to validating web payment flows and answering exam questions that hinge on subtle scoping details.
