Episode 21 — Protect Stored Account Data With Zero Doubt.
This episode covers the storage side of payment security, because PCI QSA exams routinely test whether you can distinguish what may be stored, what must never be stored, and what protections are required when account data exists in any form. You’ll define cardholder data versus sensitive authentication data, then work through practical storage locations that catch teams off guard, such as application logs, debug files, database replicas, data lakes, support exports, and backups. We explain core protection concepts, including data minimization, retention limits, truncation, masking, hashing, encryption, and access restrictions, and we focus on how a QSA verifies each claim with evidence rather than trusting statements. Troubleshooting guidance addresses messy realities like legacy fields, inconsistent masking, environment drift, and conflicting data maps, along with how to prove that storage is controlled across the full population. By the end, you should be able to evaluate stored data protections with a clean, defensible approach that matches both exam expectations and real assessment practice.
