Introduction:
Payment security is a growing priority in higher education as universities process thousands of credit card transactions for tuition, donations, ticket sales, and more
The Payment Card Industry Data Security Standard (PCI DSS) helps safeguard these transactions by setting rigorous security requirements. In March 2022, the PCI Security Standards Council released PCI DSS version 4.0, the first major update to the standard since 2018. This new version introduces significant changes that university IT leaders, security teams, and finance administrators must understand and implement. Non-compliance can lead to hefty fines, data breaches, and reputational damage, so adapting to PCI DSS 4.0 is both a compliance mandate and a strategic move to protect students, faculty, and the institution’s financial health.
Why PCI DSS 4.0 Matters for Higher Education:
Colleges and universities are unique environments with decentralized departments and complex IT systems. They are also prime targets for data breaches due to the high volume of payments and diverse payment channels on campus. PCI DSS 4.0 is designed to address modern threats and technologies, making compliance a critical task for higher ed. By embracing PCI DSS 4.0, universities will not only meet the updated requirements but also strengthen their overall security posture, maintain the trust of students and donors, and ensure continuity of campus operations.
PCI DSS 4.0 Overview and Timeline
PCI DSS is a global security standard that any organization handling cardholder data must follow. Version 4.0 continues this mission with updated goals that emphasize flexibility, continuous security, and robust validation. Notably, PCI DSS 4.0 retains the same 12 core requirement categories as 3.2.1, but it introduces new sub-requirements and modifications to address the evolving threat landscape. The standard was developed with extensive industry feedback and is geared toward helping organizations keep pace with changes in payments technology and cybercrime tactics.
Universities must pay close attention to the implementation timeline for PCI DSS 4.0. The new standard was officially released on March 31, 2022, kicking off a transition period through March 31, 2024.
During this period, institutions could choose to be assessed under PCI DSS 3.2.1 or 4.0 while preparing for the new requirements. As of March 31, 2024, PCI DSS v3.2.1 is retired and PCI DSS 4.0 becomes mandatory for all compliance assessments. However, not all new requirements took effect immediately – a subset of “future-dated” requirements remain best practices until March 31, 2025, when they become fully mandatory.
This phased timeline gives universities time to implement changes while maintaining compliance. In summary:
- March 31, 2022: PCI DSS v4.0 released (v3.2.1 remains active during transition)
bdo.com
- March 31, 2024: PCI DSS v3.2.1 retired; compliance must use v4.0 moving forward.
arrowpayments.com - March 31, 2025: All new “future-dated” PCI DSS 4.0 requirements become effective and mandatory.
Universities should use this timeline to plan their compliance upgrades, ensuring critical controls are in place by 2024 and more advanced or optional controls by 2025.

Major Changes from PCI DSS 3.2.1 to 4.0
PCI DSS 4.0 brings a series of updates designed to modernize the standard. Understanding these key changes is the first step in a successful transition:
- Greater Flexibility and Customization: PCI DSS 4.0 introduces a more flexible, outcome-based approach to meeting security objectives. In prior versions (3.2.1), requirements were very prescriptive, often a one-size-fits-all checklist. In 4.0, organizations have the option of a “customized implementation” for controls, allowing alternative methods to meet the intent of a requirement.
360advanced.com
This means universities can leverage different technologies or processes that suit their complex environments, as long as they achieve the same security outcome. For example, 4.0 provides increased allowance for things like group or shared accounts under strict conditions, which previously were discouraged

Any customized approach must be thoroughly documented and justified with risk analysis and testing to prove it meets the intent
360advanced.com
- Security as a Continuous Process: A cornerstone of PCI DSS 4.0 is treating security as an ongoing, continuous process rather than a once-a-year checkbox.
In 3.2.1, many organizations approached PCI compliance with an annual audit mentality. The new standard emphasizes continuous monitoring and regular testing of critical systems.
This shift is crucial given that threats evolve constantly and a lapse in security for even a short time can lead to an incident. For universities, this means moving to year-round vigilance – conducting frequent reviews, scans, and updates to remain compliant at all times, not just at audit time.
- Enhanced Validation and Reporting Requirements: To support that continuous security mindset, PCI DSS 4.0 strengthens validation methods and reporting. There is a push for clearer evidence of compliance: organizations are expected to maintain more thorough documentation, perform formal risk assessments, and align their reporting more closely with the requirements. For instance, PCI 4.0 introduces assigned roles and responsibilities for each requirement and additional guidance within the standard to aid in implementation
posrg.com
The reporting process (such as Self-Assessment Questionnaires and Reports on Compliance) has been refined for better transparency and consistency – information reported in the SAQ/ROC is now more explicitly tied to the Attestation of Compliance
While these changes mean more work preparing documentation, they ultimately help universities identify gaps and demonstrate their security efforts more clearly to assessors and bank partners.
- Stronger Authentication Standards: Perhaps one of the most significant technical changes is the increased focus on authentication. Under PCI DSS 3.2.1, multi-factor authentication (MFA) was required for admin accounts with remote access and for any user accessing card data remotely.
PCI DSS 4.0 expands MFA “everywhere” – all access into the cardholder data environment (CDE) now requires MFA, even for local access by internal personnel.
cpl.thalesgroup.com
In addition, password policies have been updated: the minimum password length increases from 7 to 12 characters and aligns with modern guidelines (e.g. encouraging passphrases over complex, hard-to-remember strings).
360advanced.com
The new standard also leans on guidance from NIST, meaning practices like 90-day password expiration are no longer mandated if strong passwords and MFA are in place.
arrowpayments.com
These changes address the reality that weak authentication is a common breach point, and they are critical for universities where many users (sometimes including student workers) access payment systems.
Universities will need to update campus password policies and ensure MFA is in place for any system touching payment data.
- Emerging Technologies and E-commerce Security: Higher education has rapidly adopted cloud services, mobile payments, and even Voice over IP (VoIP) for handling payments. PCI DSS 4.0 explicitly addresses these emerging technologies with new guidance and requirements.
For example, there are new requirements around e-commerce payment pages to mitigate online skimming and phishing attacks.
One notable change is for universities using hosted payment pages or iFrames (qualifying for SAQ A compliance). PCI DSS 4.0 now requires quarterly vulnerability scanning of all e-commerce pages that redirect or embed third-party payment forms– a step not required under 3.2.1. This change was introduced because even fully outsourced payment pages can be targets for web skimming attacks (Magecart-style breaches). Additionally, institutions must ensure new technologies like VoIP (used in call centers for phone payments) are included in scope and secured under PCI 4.0 controls.
The bottom line: universities need to inventory any new tech handling card data and apply the appropriate PCI 4.0 controls, such as encryption, secure configuration, and regular testing, to those systems.
In total, PCI DSS 4.0 includes more than 60 new or modified requirements, although many are best practices until 2025. The table below summarizes some of the key differences between PCI DSS 3.2.1 and 4.0, with context for higher education:
PCI DSS 3.2.1 vs 4.0: Key Differences (Higher Ed Context)
| Aspect | PCI DSS 3.2.1 (Legacy Standard) | PCI DSS 4.0 (Current Standard) |
| Compliance Mindset | Emphasized annual audits/assessments – a point-in-time evaluation of security controls.Compliance often treated as a once-yearly project. | Emphasizes continuous security monitoring and improvement. Treats compliance as an ongoing process with regular testing and reviews. This requires universities to integrate PCI tasks into daily/weekly operations, not just annual checkups.
|
| Authentication | MFA required for remote or admin access to the CDE; 7-character min password with periodic rotation
Basic authentication controls in place, but some shared accounts still existed in campus settings (against best practices). |
MFA required for all access into the cardholder data environment (including internal access) . Passwords must be 12+ characters with modern password policies (aligning with NIST guidelines). Shared or group accounts are only allowed with rigorous compensating controls and risk justification. Strong authentication reduces risk of account breaches in university systems.
|
| Risk Assessments | Annual risk assessment recommended, but less integrated into each requirement. Limited flexibility – organizations often followed a fixed testing frequency (e.g. quarterly scans) without variation.
|
Risk-based approach with targeted risk analyses to determine control frequencies.
Universities can adjust how often they perform certain activities (like scans, training) based on documented risk assessments. This adds flexibility (and responsibility) to set frequencies that suit campus risk profiles, rather than strictly following generic schedules. |
| Requirement Flexibility | Prescriptive controls with a one-size-fits-all approach. Alternatives had to be justified as compensating controls (often difficult to document and get approved). | Customized Implementation option: allows different methods to meet a requirement’s objective, enabling use of new technologies or approaches.Requires detailed documentation and QSA validation, but helpful for universities with unique IT environments. Greater flexibility to use third-party solutions or cloud services as long as security outcomes are met.
|
| E-commerce & Web Payments | Outsourced web payments (SAQ A) had minimal technical requirements – no vulnerability scans required for hosted payment pages. Focus was on network security for self-hosted systems, less on content of externally hosted pages.
|
New e-commerce security requirements: Even hosted payment pages must undergo quarterly vulnerability scans and integrity checks.
PCI 4.0 recognizes that universities’ online payment portals are targets for skimming, so it adds requirements to regularly scan and promptly fix web vulnerabilities. Also adds anti-phishing and user awareness measures to protect against social engineering.
|
| Logging & Reporting | Logging of access and regular log reviews were required (e.g. daily log review) under requirement 10, but compliance reporting was mostly about meeting each control at audit time. Attestation of Compliance was separate from detailed ROC/SAQ content. | Enhanced logging, reporting, and governance: PCI 4.0 adds clarity that security must be continuously validated. It introduces new controls like more frequent testing of controls, and better alignment of assessment reports with the attestation. Universities must assign clear responsibilities for each requirement and maintain documentation to prove compliance throughout the year. The Attestation now closely reflects the actual controls in place, ensuring more accountability in reporting.

Case Study: Transitioning to PCI DSS 4.0 at Fictional State University
To illustrate how a university might approach PCI DSS 4.0, consider Fictional State University (FSU), which operates dozens of merchant accounts across its campus (in the bursar’s office, athletics, university store, and online portals). FSU knew that PCI DSS 4.0’s deadlines were approaching and convened a cross-functional PCI 4.0 Task Force led by IT security, the treasury office, and departmental finance staff.
Assessment and Planning: The task force began in early 2023 with a comprehensive assessment of current PCI compliance. They reviewed FSU’s payment systems against PCI 3.2.1 requirements and identified gaps relative to 4.0’s new standards. For example, they found that while MFA was used for remote admin access, it was not yet enabled for certain internal users who access cardholder data on campus. Their e-commerce donation site, managed by a third-party, qualified for SAQ A – under 3.2.1 it required no scanning, but under 4.0 it would need quarterly vulnerability scans that FSU had never conducted. These findings helped FSU prioritize areas to address.
Implementation Phases: FSU developed a phased roadmap to meet PCI DSS 4.0:
- Phase 1 (2023): Address high-priority technical controls. The university’s IT team rolled out MFA for all staff who access payment systems, including cashiers and business office personnel, satisfying the expanded authentication requirement
arrowpayments.com
cpl.thalesgroup.com
They also updated password policies in the campus identity management system to require 12-character passwords and educated users about using passphrases instead of simple words. The network team reviewed firewall (now “network security controls”) configurations to ensure they met 4.0’s stricter guidelines and documented a formal cryptographic architecture (encryption key management scheme) as required by the new standard. FSU’s web developer coordinated with their payment gateway to arrange for quarterly scans of the donation website, ahead of the mandatory date. - Phase 2 (Late 2023): Enhance monitoring and processes. FSU invested in a security information and event management (SIEM) system to aggregate logs from all cardholder systems, making it easier to perform the daily log reviews and detect anomalies continuously. They implemented an automated tool for file integrity monitoring on critical servers to catch unauthorized changes in real-time. Recognizing the emphasis on continuous compliance, FSU scheduled quarterly internal audits of PCI controls (simulating portions of the annual assessment) to ensure no control would fall out of compliance between yearly reviews. The task force also began drafting expanded documentation – updating network diagrams, asset inventories, and writing a procedure for conducting targeted risk analyses. For instance, they did a risk analysis on how often to run internal network scans, ultimately deciding to increase from semi-annually to monthly based on the risk to student data.
- Phase 3 (Early 2024): Policy, Training, and Final Touches. FSU updated its official PCI compliance policy to incorporate 4.0 changes, clearly assigning responsibility for each requirement to specific roles (IT security manager for technical controls, Finance director for ensuring quarterly user training, etc.). They ran training sessions for department cashiers and IT staff to familiarize everyone with new security procedures – including how to respond to vulnerability scan reports and stricter physical security checks of payment terminals. Before the March 2024 deadline, FSU engaged a Qualified Security Assessor (QSA) to perform a gap assessment. The QSA’s feedback was used to remediate any last minor issues. By the time PCI 4.0 became mandatory, Fictional State University had transitioned all required controls and even some future-dated best practices well ahead of the 2025 final deadline.
Outcome: The fictional case study demonstrates that with early planning, stakeholder buy-in, and a phased approach, universities can achieve compliance with PCI DSS 4.0 on time. FSU not only met the requirements but also improved its overall security—implementing MFA broadly, gaining better visibility through continuous monitoring, and fostering a culture of proactive risk management. When FSU underwent its official PCI assessment under 4.0, it passed with flying colors, giving leadership and the campus community confidence that payment data is well protected.
Practical Next Steps for PCI DSS 4.0 Compliance in Higher Ed
Achieving PCI DSS 4.0 compliance may seem daunting, but a clear action plan will guide universities through the transition. Here are practical next steps for university IT and compliance teams:
- Stay Informed on Requirements: Keep up with PCI SSC guidance, FAQs, and industry updates on PCI DSS 4.0
Regulatory details can evolve, so designate a team member to monitor any new guidance or clarifications from the PCI Council or higher-ed security forums. Understanding the fine print of new requirements (e.g. exact MFA rules or encryption updates) is crucial before making changes. - Perform a Gap Assessment: Conduct a thorough review of your current cardholder data environment and security controls against the PCI 4.0 requirements. Identify where you are not meeting the new standard. Common gaps to check include password length, MFA coverage, whether you have processes for continuous log monitoring, and if all required documentation (like risk assessment records or cryptographic diagrams) is in place.
- Prioritize Risks and Quick Wins: Not all gaps carry equal risk. Use a risk assessment to prioritize remediation efforts. For example, a missing MFA on an admin account is a high-risk issue to fix immediately, whereas a documentation shortfall might be important but lower risk. Focus first on high-risk vulnerabilities that could lead to breaches, such as insecure remote access or unscanned web apps, then tackle governance and paperwork requirements.
- Develop a Compliance Roadmap: Create a detailed plan with owners and deadlines for each remediation item.
Include the key dates from the PCI DSS 4.0 timeline in your planning. Your roadmap should ensure that by March 2024 all mandatory controls are in place, and set targets to implement the future-dated requirements well before March 2025. Breaking the work into phases (as shown in the FSU case study) can help manage resources and track progress. - Upgrade Security Controls and Tools: Implement the necessary technical controls and upgrades identified in your plan.
This may involve: deploying an MFA solution campus-wide; updating configurations on network devices to comply with new firewall (network security) rules; encrypting any stored cardholder data with strong cryptography; setting up vulnerability scanning services for web applications; and ensuring all card-reading devices are protected (e.g. using PCI-approved point-to-point encryption to reduce scope). Many universities will need to engage an Approved Scanning Vendor (ASV) for the first time for SAQ A websites – start that process early. - Policy and Documentation Updates: Revise your policies and procedures to reflect PCI DSS 4.0’s emphasis on continuous monitoring and risk analysis. Document everything – network diagrams, data flow diagrams, risk assessment reports, and compliance checklists.
Ensure that you have assigned responsibilities for each PCI requirement to specific roles or departments. University environments can be decentralized, so clarity in who is responsible for what (e.g. who reviews logs daily, who manages user access reviews, who coordinates scans) is key to ongoing compliance. - Train Staff and Stakeholders: Humans are a critical part of the compliance equation. Update your training programs to educate employees about the new PCI 4.0 requirements and why they matter.
This includes IT staff, cashiers, business office personnel, and anyone handling payment data. Training should cover secure authentication practices (no shared passwords, MFA usage), recognizing phishing attempts (since PCI 4.0 addresses social engineering threats), and the importance of following new procedures like responding to system alerts or scan findings. - Engage a QSA or External Expert: If resources allow, consult with a Qualified Security Assessor or a higher-ed focused PCI compliance partner (like Arrow Payments) for a pre-assessment or advisory services.
An experienced external assessor can validate your interpretations of the requirements, perform a readiness review, and ensure there are no blind spots in your compliance efforts. They can also help universities navigate the customized implementation options properly and efficiently. - Test, Monitor, and Iterate: Once changes are implemented, don’t wait for the official audit to test them. Perform internal audits or mock assessments to verify compliance. Set up continuous monitoring processes – such as automated alerts for any system out of compliance, monthly department check-ins, and periodic scans beyond the required minimum. Treat PCI DSS 4.0 compliance as an ongoing cycle: detect issues, fix them, and update processes. This continuous improvement approach will make the annual assessment a formality rather than a firefight.
- Plan for Future-Dated Requirements: Some of the new PCI 4.0 requirements labeled as “best practices until March 2025” might take more effort (for example, implementing sophisticated network segmentation or instituting phishing resistance measures). Don’t ignore them – incorporate them into your 2024 projects so that you’re not scrambling at the last minute.
Early adoption of these practices will further strengthen security in the interim.
By following these steps, university teams can confidently navigate the transition to PCI DSS 4.0. Remember that compliance is not just about passing an audit – it’s about protecting the campus community’s financial data every day. In the words of PCI SSC, security must be “a continuous process”
With PCI DSS 4.0, universities have an opportunity to modernize their payment security, reduce the risk of breaches, and demonstrate a strong commitment to safeguarding sensitive information.
Conclusion:
PCI DSS 4.0 represents a new era of payment security for higher education. By understanding the changes and taking proactive steps now, colleges and universities can ensure they remain compliant and secure as the deadlines approach. The effort invested in stronger authentication, continuous monitoring, thorough risk management, and staff training will pay off not only in compliance reports but in the prevention of costly security incidents. Universities that embrace PCI DSS 4.0 as a catalyst for improving their payment systems will be well-positioned to protect their students, parents, and alumni – building trust that extends far beyond the balance sheet. As we’ve discussed (and in [our earlier post on PCI compliance in higher ed]), maintaining PCI compliance is ultimately about upholding the trust and safety of your campus community. With a future-focused and solution-oriented approach, higher education institutions can turn PCI DSS 4.0 compliance into a strategic advantage, creating a safer environment for all transactions campus-wide.
