Episode 4 — Define PCI roles and nail precise scope

This episode clarifies the key PCI roles you’ll see on the ISA exam and in real programs, then uses those roles to explain why scope decisions succeed or fail. You’ll define the responsibilities and boundaries of merchants, service providers, assessors, internal stakeholders, and system owners, and you’ll connect those roles to shared responsibility models that often create gaps. We’ll walk through the practical meaning of a cardholder data environment and how scoping is determined by where account data is stored, processed, or transmitted, plus any connected systems that can impact security. You’ll learn common scoping errors, such as assuming a vendor “handles PCI,” ignoring admin pathways, or treating segmentation claims as facts without proof. We’ll also cover how to document scope decisions in a defensible way, using asset inventories, network diagrams, and data flow narratives that withstand scrutiny.
