The Payment Card Industry Security Standards Council released its updated version of its Data Security Standards on March 31, 2022, its first update since version 3.2.1 in 2018. PCI DSS v4.0’s larger goals include:
The council allowing for flexibility does not mean that everything is a free-for-all. On the contrary, the new standards provide stricter guidelines for certain initiatives and tighter definitions for timelines that will make continuous vigilance even more important—not just at audit time, but throughout the year.

The PCI DSS v4.0 includes expanded requirements for multi-factor authentication (MFA). In the new data standards, MFA is required for all non-console access into the cardholder data environment (CDE) for personnel with administrative access. The goal is to reduce the probability that a malicious actor can gain access to CDE systems by requiring authentication via multiple means. These means should include at least two of the following three:
The guidelines also specify that the length of a password or passphrase should increase from 7 to 12 characters and must include both numbers and alphabetical characters. This expanded use of MFA could create issues related to both cost and complexity for your organization. By reviewing your options now, you will have the time and space to choose the best option for your team.
Phishing attacks will continue to pose a threat for organizations as long as humans have computer access. Phishing attacks grow more sophisticated and remain relentless—so your efforts to protect against them must grow and remain too.
You will need automated anti-phishing mechanisms to meet the requirements and to keep the cardholder information you hold more secure. Parameter’s Advisory Services can help you choose the anti-phishing platform that is the right fit for your organization.
In the new PCI standards, timelines are more specifically designed and thus stricter. Whereas, before, an annual scan could mean doing the scan in January of one year and December of the next. That is to say, the time between activities was not specified. Now, an annual scan means that it must take place on the same day of every year.
Likewise, a company looking to meet past PCI standards might have conducted a quarterly action in January of the first quarter and May of the second. Now, a quarterly scan must happen: once every three months; between 90 and 92 days; or the nth day of every three months. In a similar vein, actions required daily could be interpreted as needing to happen every business day—to the exclusion of nights, weekends, and holidays. The new standards in PCI v4.0 define daily as every calendar day to avoid confusion or interpretation. For activities required periodically, the organization hoping to demonstrate compliance must submit its own specific definition for how frequently it will complete these activities. The organization can fail the assessment if it is not completed by the timeline.
Organizations should update their PCI DSS scope frequently (at least annually) to help ensure that the PCI DSS scope continues to align with the organization’s current business objectives and processes. Annual requirements for PCI v4.0 include identifying:
A policy advisor can help you craft these policies and procedures—not only to prepare you for an annual PCI audit but to keep your cardholder data safe year-round.
No matter your company size, you will need to adapt to the new timeframes. For larger teams, vacations, sick time, and meetings for your leadership will make running more regular compliance program more challenging. Smaller teams will have to put programs in place to track. Mid-sized organizations will have trouble bridging this gap. Staying vigilant is key to sticking to compliance requirements.
But you need to start sooner. Now is the time to do a gap analysis to determine how ready your organization is for the new changes, where you will need adjustments and improvements, as well as how to prepare for them. It takes to build up inertia in decision making, budgeting, and procurement to meet the new requirements. By starting now, you will have a leg up on the competition and the bad actors and will have the appropriate amount of time for review and implementation.
