PCI DSS 4.0 Made Simple: A Comprehensive Guide to the Payment Card Industry Data Security Standard

Introduction

Payment card data remains one of the most targeted assets in the digital economy. As cybercriminals refine their tactics and payment ecosystems grow more complex, organizations that process, store, or transmit cardholder data face increasing pressure to strengthen security controls and demonstrate compliance.

PCI DSS 4.0 Made Simple: A Comprehensive Guide to the Payment Card Industry Data Security Standard by Willy Danenberg addresses this challenge by translating the latest version of PCI DSS into clear, actionable guidance. Rather than overwhelming readers with technical detail, the book explains what PCI DSS 4.0 requires, why the changes matter, and how organizations can implement controls with confidence.
