Episode 15 — Protect stored account data from unauthorized exposure
This episode explains how PCI thinks about protecting stored account data, with a focus on what the ISA exam expects you to verify: where the data lives, who can reach it, and what controls prevent misuse. You’ll review the definitions and handling rules around PAN, sensitive authentication data, and data retention, then learn how storage protections are validated through design and evidence rather than claims. We’ll cover practical controls such as data minimization, truncation, tokenization boundaries, access restrictions, and secure storage design, and we’ll discuss how backups, logs, exports, and analytics systems commonly reintroduce risk. You’ll work through scenarios like a database that stores full PAN for “business needs,” a reporting warehouse that receives transaction fields, or a support process that captures screenshots, and you’ll learn how to recommend changes that reduce exposure while maintaining business function. We’ll also cover what strong evidence looks like, including data discovery results, schema reviews, retention settings, and access trails that prove protections are real.
