PCI DSS V4.0 Frequently Asked Questions

What is PCI DSS version 4.0?2023-11-10T13:28:39+00:00
  • PCI DSS stands for the Payment Card Industry Data Security Standard.
  • PCI DSS compliance is mandatory for any business that accepts credit and debit cards.
  • It is a set of technical and operational requirements set by the PCI Security Standards Council (SSC) to protect payment card data.
  • Merchants need to show to their acquiring banks or payment service providers that they are processing the payments in such a way that does not leave their business at risk of a data breach, in line with the PCI DSS Compliance Programs set out by the card schemes (VISA, Mastercard etc.).

Version 4.0 marks the first significant change to the standard in nearly a decade. It is a response to both changes in technology and the evolving threat landscape facing businesses today. It aims to better support businesses in their efforts to secure payment card data and improve security measures to protect against potential risks.

What’s changing?2023-11-10T13:30:10+00:00

There are some new requirements for certain business types and some requirements have been removed. In addition, many of the existing requirements now include new controls. What will change for your business depends on your SAQ (Self-Assessment Questionnaire) type.

How these changes impact you will be determined by your Self-Assessment Questionnaire SAQ type. The portal journey has been updated to ensure that all changes have been factored in, to ensure that you are reporting against version 4.0.

How do I know my SAQ type?2023-10-25T16:49:13+00:00

Once you have completed your business profile on the portal, your SAQ type will be displayed on your dashboard, under “Your business profile, SAQ type” see image below. It is important that you answer as accurately as possible.

 

Portal Dashboard showing SAQ Type – This business is SAQ Type B-IP.

How do I know what’s changed in my SAQ type?2023-09-13T14:38:51+00:00

The portal will guide you through the changes. As you may have some new requirements, we recommend starting your assessment as early as possible in advance of your renewal date. If you need assistance, you can reach out to us using the support information available on your portal or email communications.

Can I validate against the current version of the standard?2023-11-10T13:31:11+00:00

From within our portal, you can validate against the current version of the standard version 3.2.1, up until the date that version 4.0 is implemented. After the update has been applied and version 4.0 is available, your reporting journey will be against version 4.0 of the standard. If you do have a valid Attestation of Compliance (AoC) for version 3.2.1 that you wish to upload, you can do so up until March 31st, 2024. After that date only version 4.0 will be accepted.

What happens if I have started but not completed my compliance journey when version 4.0 is implemented?2023-11-10T13:32:00+00:00

If you have started but not completed your compliance journey, you will need to restart once version 4.0 is implemented.

Will version 4.0 take longer to complete than the previous version?2023-11-10T13:32:52+00:00

Most requirements in PCI DSS version 4.0 have been re-worded and/or re-ordered so filling out your SAQ for version 4.0 may take a bit more time than usual initially. SAQ types that apply to ecommerce businesses as well as those using point-of-sale systems, or other payment application systems, connected to the internet have had a number of significant changes.

Completing version 4.0 assessment may take longer due to newly applicable requirements. It may help to be prepared in advance – know who to all in relation to the set up and security of your payment systems e.g., your eCommerce website, point-of-sale system etc.

Are all of the changes in version 4.0 applicable immediately?2023-11-10T13:34:28+00:00

No, some of the more advanced new requirements are designated with a future date to give businesses extra time to complete their implementation. Requirements that are future dated are considered as best practice until March 31, 2025, at which point they become effective. To remain compliant you must implement all applicable new requirements on or before the March 31, 2025. After this date, these requirements become mandatory. You will receive ample notification with instructions to help you meet future dated requirements applicable to your SAQ type.

Can my business be PCI DSS compliant using version 4.0, if I use a third party service provider (TPSP) that is validated to PCI DSS v3.2.1?2023-11-14T15:19:10+00:00

Yes, you can.

If your third party’s PCI DSS assessment is current (that is, completed within the last 12 months) and was against the version of the PCI DSS current at the time of that assessment (so v3.2.1), then your assessor may mark as “Not Applicable” those Requirements for which you rely upon the TPSP but for which they have not yet been assessed.

The other scenario is where your TPSP has been assessed to version 4.0 but that assessment was completed prior to the effective date of new Requirements. Those future-dated new Requirements – that the TPSP will be responsible for meeting on your behalf – were not included in the TPSP’s assessment; they are marked as Not Applicable. Which means for your own assessment, those new Requirements for which you will rely upon the TPSP can again be marked as ‘Not Applicable’ by your own assessor.

There are a couple of FAQs that explain the scenarios here: FAQ 1282 and 1564.

Our website uses a URL redirect/embedded iFrame so we now need to do ASV scans. Do I now need to complete an ASV scan?2023-11-10T13:39:25+00:00

Yes, If your website uses a URL redirect/embedded iFrame you will need to complete ASV scanning. ASV or External Vulnerability Scans is a non-intrusive website scan, that helps identify vulnerabilities that may lead to a compromise of your customers’ card data.

Are there any changes to External Vulnerability Scanning requirements?2023-11-10T13:42:31+00:00

If you are currently required to complete External Vulnerability Scanning, there are no changes. You will continue to scan and attest to your scans in exactly the same way. Please note, that some Ecommerce merchants who are classified as SAQ A may be required to perform External Vulnerability Scanning for the first time. If your website uses a URL redirect/embedded iFrame you will need to complete ASV scanning. If you are unsure, please check with your web developer. If scanning is required, you will receive detailed instructions.

If you meet the requirements for an External Vulnerability Scan, you must obtain a new scan within 90 days of a significant change to your website or web servers.
Note: The target environment for the external vulnerability scans must include your ecommerce web redirection servers.

Will previously attested, completed/submitted SAQ and scan pdf documents continue to be available from the portal?2023-11-10T13:43:24+00:00

Historical records relating to previously attested, completed/submitted SAQ and scan documentation will continue to be available from within the scan and SAQ widgets on your merchant dashboard, as they are today.

Will there be new policy and procedure templates?2023-11-10T13:43:58+00:00

Where applicable, policy and procedure templates have been updated. We recommend you review your existing policy and procedure documents and update them if necessary.

Where can I get help if I need assistance when completing version 4.0?2023-11-10T13:44:27+00:00

Each question in the Self Assessment Questionnaire (SAQ) has supporting guidance and applicability notes. If you need additional assistance, you can reach out to us using the support information available on your portal or email communications.

How is requirement 8.3.6 being presented given it is future dated but falls back on previous version 3.2.1 requirement 8.2.3?2023-11-16T17:20:57+00:00

In PCI DSS version 4.0 question 8.3.6 states that password complexity will require a minimum length of twelve characters (where twelve characters are supported, otherwise a minimum of eight characters is required), however this is a future dated requirement, best practice until after 31st March 2025. Until then, the PCI DSS version 3.2.1 version of this same requirement (8.2.3) should be applied.

8.2.3 asks: (a) Are user password parameters configured to require passwords/passphrases meet the following? – A minimum password length of at least seven characters – Contain both numeric and alphabetic characters Alternatively, the passwords/passphrases must have complexity and strength at least equivalent to the parameters specified above.

The version 4.0 SAQ question itself does not include any text from the version 3.2.1 question, and only refers to it in the applicability notes. Therefore, we have included a screen in the profile, that is presented to merchants of the following SAQ types: D, A-EP, C, C-VT and A.

“Do you enforce a minimum password length of seven characters, containing both numeric and alphabetic characters, for user accounts on all POS devices, computers and systems in your business?”

If the question is answered ‘Yes’, we auto-answer SAQ question 8_3_6 as ‘Yes’ and present a pop-up advising it is best practice until 31st March 2025.

Pop-up alert if answered yes: Please note: this is best practice until 31st March 2025, after which password complexity will require a minimum length of twelve characters (where twelve characters are supported, otherwise a minimum of eight characters is required)

If the question is answered ‘No’, we do not auto-answer SAQ question 8_3_6 and instead you will need to respond to this question directly in the SAQ.

Will my previous business profile answers be retained following the update?2023-11-16T17:21:23+00:00

Yes, all answers previously provided as part of your profile will be retained following the update so you can review what was previously submitted. You will be able to change these answers as you progress through the profile should anything with respect to how you store, process and/or transmit payment card data have changed. Depending on your processing methods, you may be asked additional questions that may or may not change the outcome of your subsequent profile questions, your SAQ type, SAQ auto-answering effects and requirement to perform ASV scanning on your environment.

Will my previous SAQ answers be retained for the same/similar requirements following the update?2023-11-16T17:21:46+00:00

On completion of your business profile, we will determine what answers from your previous assessment can be mapped and applied to the same or similar question in version 4.0 so you do not need to answer those questions again.

There are exceptions to this:

  • If we detect a change in SAQ type following completion of your business profile
  • If multiple version 3.2.1 requirements were merged into a single requirement in version 4.0, we will only apply your previous answers if all the answers to the merging questions in version 3.2.1 are the same. For example:
    • Requirement 3.2.2 in version 3.2.1 maps directly to requirement 3.3.1.2 in version 4.0, however,
    • Requirements 3.6.5(a), 3.6.5(b) and 3.6.5(c) in version 3.2.1 are merged into requirement 3.7.5 in version 4.0, so we will only apply your existing answers to 3.7.5 if 3.6.5(a), 3.6.5(b) and 3.6.5(c) are all answered and all answered with the same response.
  • If you previously indicated that you are not compliant with a particular requirement, you will be required to re-assess and provide a response to that question again.
  • Any of your previous assessment questions that were auto answered by the system, because of how you answered your business profile, will not be retained from version 3.2.1 to version 4.0. However, on completion of your business profile, a new set of auto-answer effects will be applied to your current assessment based on the new rules defined for version 4.0.
