Episode 5 — Hunt cardholder data across every environment
This episode teaches you how to locate account data in the places teams forget to look, a skill that directly supports ISA exam questions about scope, evidence, and control design. You’ll define what counts as cardholder data and sensitive authentication data, and you’ll learn why confusing those categories leads to serious compliance and security failures. We’ll cover practical discovery methods across endpoints, servers, databases, file shares, log systems, SaaS platforms, and cloud storage, including how data ends up in unexpected locations through troubleshooting, exports, email, or poorly controlled integrations. You’ll also learn how to validate claims like “we don’t store card data” by checking retention settings, tokenization boundaries, and application behaviors that create shadow copies. To make this real, we’ll use scenarios such as support teams collecting screenshots, developers logging payloads, and finance systems storing receipts, and we’ll discuss best practices for remediation that reduce scope while improving security posture.
