In a move that represents a significant milestone and evolution in payment data security, the Payment Card Industry Data Security Standard (PCI DSS) is updating from v3.2.1 to v4.0.

If your organisation deals with payment data in any way, it will need to adhere to the new standard, as it is crucial for safeguarding sensitive payment information.

Organisations have until March 31st to become compliant with 13 requirements of the new PCI DSS, with a further 51 more technical requirements to follow in a second phase in 2025.

Updating the standards

PCI DSS v4.0 is a dramatic leap in security standards, demanded by an increasingly dangerous and continuously changing IT landscape.

These changes are not just a by-the-numbers standard update, but instead, reflect the need for organisations to strengthen their defences against evolving threats and vulnerabilities.

These include things like:

• Software vulnerabilities in payment processing applications or systems.
• Sophisticated cyber attacks like malware, phishing, and social engineering attacks targeting payment systems.
• Insider threats posed by employees, contractors or third-parties with access to payment data.

The updated standard underlines the industry’s commitment to staying ahead of malicious actors and cybercriminals, ensuring the safety of sensitive payment information.

It’s crucial that organisations recognise the importance of this transition and allocate resources accordingly, so that the adaptation to the new standards is a seamless one.

What are the key changes in PCI DSS v4.0?

The transitions to PCI DSS v4.0 bring significant changes to data security standards, including:

• The introduction of 13 new broad requirements by March 31st, 2024.
• A further 51 new technical requirements to be implemented by April 2025.
• Updated Self-Assessment Questionnaires (SAQ) to reflect the evolving payment security landscape, with additional requirements to address emerging threats.

New requirements effective March 31st 2024

Your organisation needs to align its practices with these new changes, to ensure compliance, with 13 broad requirements becoming mandatory.

These 13 requirements revolve around protecting cardholder data, maintaining a vulnerability management program, implementing strong access controls, regularly monitoring and testing networks, and maintaining an information security policy.

Navigating the new PCI DSS requirements

The effective dates for these changes are non negotiable.

Organisations must understand and align their practices with these new changes to ensure compliance, and thorough assessment will be necessary for your organisation to measure the impact on your existing infrastructure and processes.

For a more detailed and granular breakdown of the requirements your organisation will need to follow, please check the official Payment Card Industry Data Security Standard version 4.0 guidance.

Addressing common questions

As your organisation transitions to PCI DSS v4.0, you may have questions about assessment validity, and the compliance of your service provider.

These include payment processors, hosting providers, managed service providers (MSPs) and any third party that handles payment information on your behalf.

It’s crucial to get clarity on any issues you may be facing to ensure a smooth transition. These questions could include:

• Will assessment results under PCI DSS v3.2.1 remain valid after the retirement date?
• How should organisations handle meeting PCI DSS v4.0 requirements if their service providers haven't made the transition yet?
• Are there any other important things to consider regarding assessment validity during the transition?
• What steps can organisations take to make sure they're communicating effectively with their service providers during this transition?
• How can organisations reduce risks associated with service provider compliance during the transition?

Effective communication and collaboration with your service provider will be the key to a smooth transition process.

To sum it all up

The transition to PCI DSS v4.0 is a critical step for organisations that in any way deal with payment data and security, and by March 31st, your organisation needs to be ready to comply with the 13 broad requirements of the new standard.

Understanding the key changes, updating SAQs for compliance, and addressing any common questions will be integral to the success of this process.

By effectively implementing all of these measures, organisations can stay compliant with industry standards and strengthen their overall data security posture around payment data and security.
