PCI DSS 4.0: Overview and Guide

The growing reliance on digital transactions has increased the need for more robust security frameworks, such as the Payment Card Industry Data Security Standard (PCI DSS) 4.0. Trust is fundamental to every credit card transaction. When customers provide their credit card information to a company, they trust that their data will be processed, stored, and transmitted securely. To meet this expectation, Visa, MasterCard, American Express, Discover, and JCB formed the PCI Security Standards Council and created the Payment Card Industry Data Security Standard, or PCI DSS for short. Ensuring compliance with these evolving standards can be challenging, especially with the complexity of modern technologies such as artificial intelligence. This blog post will guide you on how to maintain PCI Data Security Standard compliance with version 4.0.

How to Ensure You’re in Compliance with PCI DSS v4.0 — and Beyond

By following four key steps — familiarize yourself with the next version of the standard, conduct a current state analysis of your compliance with PCI DSS, identify and resolve shortcomings quickly, and embrace the need for continuous improvement — your organization can ensure compliance with PCI DSS in its current form and as it evolves.

  1. Familiarize Yourself with the Next Version of the Standard

Ensuring compliance with a new standard starts with a thorough review of the latest version. Understand what’s being removed, added, and the overall changes to assess how these might impact your business and its ability to comply. Of the changes in PCI DSS v4.0, two notable areas are implementation and authentication.

Custom Implementation: PCI DSS v4.0 introduces customized implementation, allowing organizations to develop their own security controls to meet an objective. Custom implementation means meeting a control objective through the intent of the requirement, rather than performing the control as written. This shift from prescriptive to flexible requirements provides businesses more leeway in control procedures. For external assessors, PCI-DSS v4.0 documentation must be thoroughly reviewed, and each control tested for operational effectiveness in relation to how it supports the business. Organizations will need to adjust their PCI compliance efforts to accommodate custom implementation procedures.

Authentication: PCI DSS v4.0 focuses on stronger authentication standards, incorporating NIST password guidelines. Security groups must assess how these password standards will be implemented across the organization. NIST guidelines aim to reduce user burden and minimize human error, which can expose vulnerabilities to cyberattacks. Organizations will need to update their passwords to meet these new requirements.

PCI DSS v4.0 also addresses the shift to cloud computing, introducing enhanced methodologies to evaluate controls related to the cloud.

  1. Conduct a Current State Analysis of Your Compliance with PCI DSS

Before transitioning to a new standard, assess your compliance with the existing one. Most standards build upon previous versions. Organize your assessment by analyzing people, processes, and technology.

People: Assessing people can reduce the risk of insiders exploiting cardholder data. PCI DSS v3.2.1 requires limiting access to cardholder data on a need-to-know basis. If this isn’t currently in place, it will impact your compliance with PCI DSS v4.0.

Process: Understand your current processes for risk and compliance. Regular user access reviews (UAR) are essential for identifying and managing privileged accounts. Both security and IT leaders, as well as all employees, must be aware of their role in protecting sensitive information.

Technology: Evaluate your technology across the enterprise. PCI DSS v4.0 emphasizes continuous security monitoring. Implementing integrated compliance management software can help mitigate risks to your network, infrastructure, and data.
