Cyber ResilienceThe Payment Card Industry Data Security Standard (PCI DSS) is a set of security requirements for all entities that store, process, or transmit payment card data. The standard protects cardholders’ personal and financial information from unauthorized access, fraud, and identity theft. Compliance with the PCI DSS is not only a contractual obligation, but also a competitive advantage and a best practice for any organization that handles payment card data.
The PCI DSS is a dynamic standard that evolves with the changing threat landscape and emerging technologies. The PCI Security Standards Council (PCI SSC), the global body that oversees the development and maintenance of the PCI DSS, regularly updates and revises the standard to address new challenges and opportunities in the payment industry. The latest version of the PCI DSS, version 4.0, was released in March 2022 after several consultations and feedback from various stakeholders.
The PCI DSS 4.0 is not a complete overhaul of the standard but a refinement and improvement of the existing requirements and objectives. The PCI DSS 4.0 maintains the same 12 high-level requirements and six domains as the previous version but reorganizes and rephrases them to make them more concise. The PCI DSS 4.0 also retains the same scope and applicability as the previous version, covering all payment card brands and all types and sizes of entities that handle payment card data.
The PCI DSS 4.0 is already effective but not yet mandatory and enforceable. The PCI SSC has announced a two-year transition period from March 31, 2022, to March 31, 2024, during which both versions 3.2.1 and 4.0 will be valid and acceptable. This aims to provide organizations adequate time to acquaint themselves with the PCI DSS v4. 0 updates, update their reporting templates and forms, and plan and implement those updates.

Benefits and Challenges of Upgrading to PCI-DSS V4
1. Flexibility and Customization
One of the main benefits of PCI DSS 4.0 is that it provides more flexibility and customization for achieving compliance while maintaining the same level of security. Unlike the previous version, which was more prescriptive and rigid, the new version allows organizations to choose the most suitable and effective security controls for their specific environment and risk profile. This means that organizations can tailor their compliance strategy to their unique business needs and objectives rather than following a one-size-fits-all approach.
For example, PCI DSS 4.0 introduces the concept of customized approaches, which are alternative ways of demonstrating compliance with the requirements other than the standard testing procedures specified in the standard. This approach can be used when the standard testing procedures are not applicable, feasible, or sufficient for the organization’s environment. The approach also enhances and supplements the standard testing procedures to provide additional assurance or evidence of compliance.
2. Proactive Security Practice
Another benefit of PCI DSS 4.0 is that it encourages organizations to adopt a more proactive and continuous approach to security rather than a periodic and reactive one. The new version emphasizes the importance of validating and demonstrating the effectiveness of security controls rather than just implementing them. This means that organizations must continuously monitor and measure the performance and outcomes of their security controls and ensure that they align with their security objectives and risk appetite.
While upgrading to PCI DSS 4.0 provides all the benefits mentioned earlier and more, it also brings challenges and difficulties in implementation.
The new version requires more documentation and validation of security outcomes, which can increase the complexity and cost of compliance. PCI DSS 4.0 requires organizations to provide more evidence and justification for their security decisions and actions and ensure consistency and transparency across their environment. The standard requires organizations to document their security objectives, which are the specific goals and outcomes they want to achieve with their security controls. The objectives must align with the PCI DSS requirements and the organization’s risk assessment and management processes. They must also be communicated and understood by all the organization’s relevant parties and regularly reviewed and updated.
Another challenge of PCI DSS 4.0 is that it requires more involvement and collaboration from various stakeholders within and outside the organization, potentially posing communication and coordination issues. Organizations must engage and consult with different parties, such as business units, IT departments, service providers, QSAs, and auditors, to ensure that their security controls are appropriate and effective for their environment and risk profile. Organizations must also ensure that their security controls are consistent and compatible with other PCI standards and programs, such as the PCI SSF and the PCI P2PE program.

Practical Tips and Best Practices for Preparing and Implementing the Upgrade
The upgrade to PCI DSS 4.0 is not a trivial task but a strategic and complex project that requires careful planning and execution. Organizations that handle payment card data must prepare and implement the new requirements promptly and effectively to ensure that they achieve and maintain compliance and security. The following are some practical tips and best practices for preparing and implementing a smooth upgrade to PCI DSS 4.0.
Gap Analysis
One of the first steps to prepare for the upgrade is to conduct a gap analysis, a systematic process of identifying and assessing the differences between the current and desired state of compliance. A gap analysis can help organizations understand the scope and impact of the new requirements and prioritize and allocate the necessary resources and actions to close the gaps. It can also help organizations identify and mitigate any potential risks or issues during the upgrade.
To conduct a gap analysis, organizations can follow the following steps:
- Review and compare the PCI DSS 4.0 standard and guidance documents with the PCI DSS 3.2.1 standard and guidance documents.
- Identify and document the changes and enhancements in the PCI DSS 4.0 requirements, objectives, testing procedures, and guidance.
- Evaluate and document the organization’s current state of compliance and security based on the PCI DSS 3.2.1 requirements and objectives.
- Analyze and document the gaps and differences between the current and the desired state of compliance and security based on the PCI DSS 4.0 requirements and objectives.
- Prioritize and document the actions and tasks needed to close the gaps and achieve compliance and security based on the PCI DSS 4.0 requirements and objectives.
Review of Requirements
Another essential step to prepare for the upgrade is to review the new requirements and guidance in the PCI DSS 4.0 standard and guidance documents and understand how they apply and relate to the organization’s environment and risk profile. Organizations should familiarize themselves with the concepts and terms introduced in the PCI DSS 4.0, such as the customized approach, security performance indicators, security objectives, and security roles and responsibilities. Organizations should also understand the rationale and intent behind the changes and enhancements in the PCI DSS 4.0 and how they support and align with the organization’s security goals and outcomes.
To review the new requirements and guidance:
- Read and study the PCI DSS 4.0 standard and guidance documents, and pay attention to the changes and enhancements in the requirements, objectives, testing procedures, and guidance.
- Consult and discuss with the PCI SSC, QSAs, auditors, and other experts and peers, and seek clarification and guidance on any questions or doubts regarding the new requirements and guidance.
- Apply and test the new requirements and guidance in the organization’s environment, evaluate and validate their effectiveness and suitability for achieving compliance and security, and use the PCI DSS 4.0 SAQ or ROC as a tool.
Policy and Procedure Upgrade
One of the final steps to prepare for the upgrade is to update the policies and procedures that govern and guide the organization’s compliance and security activities and ensure that they reflect and incorporate the new requirements and guidance in the PCI DSS 4.0. Organizations should review and revise their existing policies and procedures and create new ones to align and comply with the PCI DSS 4.0 requirements and objectives. Organizations should also ensure that their policies and procedures are consistent and compatible with other PCI standards and programs, such as the PCI SSF and the PCI P2PE program.
To update the policies and procedures, organizations can use the following steps:
- Review and audit the existing policies and procedures, and identify and document the areas and aspects that need to be updated or created based on the PCI DSS 4.0 requirements and objectives.
- If needed, update and revise existing policies and procedures and create new ones to align and comply with the PCI DSS 4.0 requirements and objectives.
- Approve and publish the updated or new policies and procedures and communicate and distribute them to all relevant parties within and outside the organization, such as business units, IT departments, service providers, QSAs, and auditors.
Personnel Training
Another important step in upgrading to PCI DSS 4.0 is to train and educate the staff and personnel involved or affected by the compliance and security activities and ensure that they understand and follow the new requirements and guidance in the standard.
