- PCI DSS v4.0.1 introduces clarifications and corrections without adding or removing any requirements, addressing stakeholder feedback since the release of PCI DSS v4.0.
- Notable updates include revisions to Requirements 3, 6, 8, and 12, focusing on encryption, vulnerability management, multi-factor authentication, and third-party service provider relationships.
- PCI DSS v4.0 will remain active until December 31, 2024, after which v4.0.1 will be the only supported version. The March 2025 compliance deadline for new requirements will not change.
The PCI Security Standards Council (PCI SSC) has released PCI DSS v4.0.1 as a limited update to the original PCI DSS v4.0, published in March 2022. This revision addresses formatting, typographical errors, and clarifications based on feedback from stakeholders. Importantly, no new or deleted requirements were introduced, making this update a refinement of the previous version rather than a significant overhaul. The PCI SSC Board of Advisors, Global Executive Assessor Roundtable, and Principal Participating Organizations were involved in reviewing the proposed changes during a Request for Comments (RFC) period held from December 2023 to January 2024.
Key changes in PCI DSS v4.0.1 involve clarifications across several requirements. In Requirement 3, applicability notes for issuers, and those supporting issuing services were refined, along with a clearer objective for organizations using keyed cryptographic hashes. Requirement 6 saw a return to PCI DSS v3.2.1 language, stating that the 30-day patching requirement applies only to critical vulnerabilities, and additional notes were added to clarify the management of payment page scripts. Requirement 8 introduced an applicability note that exempts user accounts using phishing-resistant authentication from multi-factor authentication requirements for non-administrative access. Updates in Requirement 12 clarified relationships between customers and third-party service providers (TPSPs). Additionally, some definitions and clarifications were added in the appendices.
PCI DSS v4.0 will remain active until December 31, 2024, after which only v4.0.1 will be supported. The March 31, 2025, deadline for compliance with new requirements remains unchanged. Supporting documents such as the Report on Compliance (ROC) template, Attestations of Compliance (AOCs), and Self-Assessment Questionnaires (SAQs) for PCI DSS v4.0.1 are expected to be published by Q3 of 2024. Organizations should reference the Summary of Changes document for detailed information on the revisions.
