Universities handle countless credit card transactions – from tuition payments and dining halls to athletic ticketing and donations. This high volume of payments across diverse campus units makes colleges prime targets for data breaches​
Source: arrowpayments.com
Ensuring Payment Card Industry Data Security Standard (PCI DSS) compliance is not optional; it’s an essential duty to protect student, parent, and donor information. Non-compliant institutions can face hefty fines, legal penalties, and reputational damage that impact student enrollment and alumni trust​.
In our earlier discussion of higher-ed PCI challenges, we noted how decentralized campus payments create a complex compliance scope​.
The good news is that by following a clear roadmap of best practices tailored to university environments, campus leaders can safeguard cardholder data and streamline compliance efforts. This guide outlines proven strategies – from network segmentation to staff training – to help university procurement teams, CTOs, and IT security leaders build a robust PCI compliance program.
Understanding the University PCI Landscape
Higher education faces unique hurdles in achieving PCI compliance. Unlike a single-unit business, a university may have dozens of departments (e.g. bookstores, cafeterias, ticket offices, online portals) accepting cards, often on different systems. Mapping out every process, person, and technology handling card data is challenging​, which can lead to blind spots in security. Many colleges operate as Level 3 merchants (20,000–1M transactions/year), allowing self-assessment questionnaires – but a data breach can instantly elevate them to Level 1, requiring annual on-site audits by a Qualified Security Assessor (QSA)​.

In short, the scope and stakes are high. To tackle this, universities must move beyond checkbox compliance to a security-first mindset.​
PCI DSS isn’t just a list of requirements; it’s a framework for protecting payment data. By treating PCI standards as baseline measures and fostering a culture of security, institutions can not only pass audits but actually reduce risk.
Below, we present a roadmap of PCI DSS best practices tailored for university payment systems. These practices address common vulnerabilities in campus environments and align with the latest PCI DSS guidelines (including new emphasis areas in PCI DSS 4.0​). From technical controls like network segmentation and encryption to process improvements like vendor management and staff training, each component is crucial in fortifying your university’s payment security.

PCI Compliance Best Practices Roadmap for Universities
The following best practices form a comprehensive approach – a “to-do list” for higher education PCI compliance. Implementing these strategies will help universities protect cardholder data across all departments and maintain continuous compliance.
1. Segment Your Network to Isolate Cardholder Data
Network segmentation is the practice of dividing your campus network so that sensitive payment systems (the Cardholder Data Environment or CDE) are isolated from other campus networks (e.g. academic networks or student Wi-Fi). This is a foundational best practice to limit the exposure of card data. The PCI Security Standards Council recommends starting with the assumption that everything is in PCI scope until proven otherwise, and then using segmentation to carve out a smaller secure network for card data​.
Source: pcisecuritystandards.org
Proper segmentation can reduce the number of systems subject to PCI controls​, making compliance more manageable. For example, a university might keep all POS terminals and payment servers on a separate VLAN or subnet that’s locked down from the rest of the campus network.
Importantly, segmentation is not a one-time set-and-forget solution. Testing your segmentation controls is critical. Under PCI DSS 4.0, if you use network segmentation to reduce scope, you must perform penetration tests of those controls at least annually (and after any significant network changes) to ensure they are effective​.
Source: campusguard.com
This means hiring internal or external pen testers to attempt to breach the CDE from other network segments, verifying that firewalls and ACLs truly block unauthorized access​. Many universities rely on segmentation because fully securing an entire campus network is impractical​
By isolating the CDE, even if a hacker infiltrates a less secure segment (say a student network), they cannot easily pivot into payment systems​.
Source: pcisecuritystandards.org
Just remember: unsegmented systems aren’t off the hook – they should not be left unprotected simply because they are “out of scope,” as attackers often exploit those to reach in-scope targets​. In summary, implement strong network segmentation to shrink your PCI footprint and regularly test it to maintain its integrity.
2. Use PCI-Validated Point-to-Point Encryption (P2PE)
Encryption is one of the most powerful tools for protecting cardholder data, and Point-to-Point Encryption (P2PE) is the gold standard for payment security in universities. A PCI-validated P2PE solution ensures that card data is encrypted the moment it’s swiped, dipped, or entered, and stays encrypted until it reaches the payment processor. Effectively, the customer’s card data never enters your campus network in plain text​
Source: arrowpayments.com
Instead, the data is immediately encrypted on a certified device and transmitted securely to the payment provider, which then returns a token to your systems to represent the transaction​.
Your systems only handle the token, not the actual card number. Even if a hacker breaches a university server or database, any stolen payment data is useless gibberish. As Arrow Payments describes, with P2PE in place, a breach of your network would yield unreadable data with no value to attackers​.
Beyond dramatically improving security, P2PE also simplifies PCI compliance for campus merchants​.
When you use a PCI-listed P2PE solution, many PCI requirements are reduced because your systems never see actual card numbers. This can shrink your compliance scope and even allow use of shorter Self-Assessment Questionnaires (SAQ P2PE-HW) instead of the full SAQ D, saving time and cost. A validated P2PE solution “reduces PCI compliance scope and costs” by preventing clear card data from ever touching your environment​.
Universities should work with their payment providers or vendors to implement P2PE for card-present transactions (e.g. new payment terminals that support encryption) and look for P2PE options in e-commerce as well. Ensure the P2PE solution is on the official PCI SSC list of validated solutions. By locking down data with encryption, you protect your campus transactions at the source and greatly ease the burden of keeping those transactions PCI compliant.
3. Conduct Regular Vulnerability Scans and Penetration Testing
Staying PCI compliant is not a one-time project – it requires ongoing vigilance. Regular vulnerability scanning and penetration testing are essential to proactively find and fix weaknesses before attackers or auditors do. PCI DSS mandates both: Requirement 11.2 calls for internal and external vulnerability scans at least quarterly (every 90 days) and after any major network changes​
Source: pcidssguide.com
These scans, often done with tools or via Approved Scanning Vendors (ASVs), probe your systems for known flaws – outdated software, misconfigurations, missing patches, etc. A university environment with many networked devices should schedule scans for all in-scope systems (servers, payment applications, terminals) on a recurring basis. When scans identify vulnerabilities (e.g. an unpatched server), IT teams must prioritize remediating them and then re-scan to verify the fix. Treat scanning as a routine “health check” for your payment environment.
In addition to vulnerability scanning, annual penetration testing is a best practice (and required for many campuses under PCI rules). A penetration test is an active simulation of attacks on your systems, ideally performed by qualified external experts. They will attempt to exploit vulnerabilities and gain access to card data, providing a real-world assessment of your defenses. Pen tests should cover the CDE and any connected systems, and as noted above, must include segmentation tests if you segment your network​
Source: campusguard.com
Many institutions perform an external pen test and an internal one at least once per year, and also whenever significant changes occur (new payment application, infrastructure overhaul, etc.). The results give you a clear roadmap of what to fix to prevent breaches. By scheduling quarterly scans and annual pen tests, universities create a cycle of continuous improvement – discover issues, patch or mitigate them, and improve your security posture over time. This proactive approach is crucial because threats are constantly evolving, and PCI DSS 4.0 emphasizes continuous security monitoring rather than a yearly checklist​

In short, regular scanning and testing keep your guard up and demonstrate to assessors that you are maintaining diligent security between formal assessments.

4. Enforce Strict Access Controls in Payment Departments
Controlling who can access cardholder data and payment systems is a core pillar of PCI compliance. Universities must implement strict access controls for all departments and staff handling payments. The principle of least privilege should apply: each user (whether a cashier, department admin, or IT personnel) should have only the minimum access necessary to perform their job. Start by ensuring that every individual with access to payment systems has a unique user ID – no shared logins! – and that strong passwords are required​
Source: arrowpayments.com
For example, the finance office and bursar staff should each log in with their own credentials to payment processing systems, using complex passwords changed regularly​
This accountability is vital; if an account is compromised or misused, you can trace it to an individual.
Beyond unique IDs and passwords, implement multi-factor authentication (MFA) for any admin or remote access to the CDE. PCI DSS 4.0 has placed a stronger emphasis on robust authentication, recognizing that compromised credentials are a common breach vector​.
Requiring a second factor (like an app code or token) for VPN access, payment portals, or management consoles greatly reduces the risk of unauthorized access. Additionally, set up role-based access controls so that only those working in payment roles can get into systems that handle card data. A dining services manager, for instance, shouldn’t have access to the development office’s donation payment system, and vice versa. Network segmentation (as discussed) also plays a role in access control by technically preventing unauthorized network access to sensitive systems.
Monitor and review access logs regularly to catch any suspicious access patterns. Remove or disable accounts promptly when staff leave or change roles. Physical access is important too – servers, POS devices, and paperwork with card info (if any) should be secured in locked areas with controlled access. By strictly limiting access to payment data, universities minimize insider risks and contain potential breaches. A strong access control program will ensure that even if credentials are stolen or an insider attempts something malicious, the blast radius is limited to only the systems they’re authorized for. This containment is key to protecting the wider campus. In summary: limit who can access card data, enforce strong authentication, and continuously monitor access – you’ll significantly reduce the likelihood of a costly incident stemming from human access.
5. Provide Annual PCI DSS Training for All Staff Involved
Technology alone cannot secure payment systems; people are a critical line of defense. Many breaches begin with human error or social engineering – a phishing email tricking an employee, or someone handling card data in an insecure way. That’s why regular security awareness and PCI DSS training for staff is paramount. In fact, PCI DSS Requirement 12.6 explicitly requires organizations to implement a formal security awareness program, including training upon hire and at least annually for all personnel involved in cardholder data handling​
Source: pcisecuritystandards.org
Universities should deliver role-based PCI training each year to anyone who processes payments or manages systems in scope (this could include cashiers, business office staff, IT admins, and even relevant student workers).
Effective training covers both PCI rules and practical security best practices. For example, staff should be taught that under no circumstances should they ever email a credit card number or store card data on a laptop or personal device. They should learn to recognize common fraud and hacking tactics – such as phishing attempts asking for passwords or card info – and how to respond (report it, don’t click links, etc.)​
Source: arrowpayments.com
Training should also remind employees of policies like not writing down card numbers on paper and ensuring payment terminals aren’t tampered with. Consider including interactive elements or real-world scenarios to keep it engaging. The goal is to instill a culture where everyone understands their role in protecting cardholder data. This extends beyond just the finance department; even IT staff who might handle systems indirectly connected to payments need to be aware of PCI implications.
An often overlooked aspect is testing and verifying knowledge – you might conduct phishing simulations or quizzes after training sessions to ensure the lessons stick. According to IBM’s research, the average cost of data breaches caused by human error is $3.33 million​.
Clearly, investing in training can pay for itself many times over by preventing just one such incident. Universities should track completion of annual PCI training as part of compliance evidence. By making PCI awareness an ongoing conversation – via annual training, monthly security tips, posters, etc. – higher ed institutions can greatly reduce risky behaviors. The result is a workforce that actively supports your compliance efforts rather than inadvertently undermining them. Remember, even the best technology can be defeated by an unaware user; training turns your people into allies for security.

6. Use Level 1 PCI-Compliant Service Providers
Another best practice for universities is to leverage Level 1 PCI-compliant vendors for payment processing and related services. “Level 1” service providers are those who meet the highest PCI DSS standards (typically processing over 6 million transactions annually or handling data for many merchants) and undergo rigorous annual audits by QSAs. When you outsource payment functions to such providers, you inherit their robust security controls and reduce your own compliance burden. For instance, a university can use a reputable third-party online payment gateway (that is Level 1 validated) for handling tuition payments or event registrations. By doing so, most of the sensitive data is hosted on the provider’s systems, not the university’s, shrinking the university’s PCI scope dramatically​.
Source: arrowpayments.com
Arrow Payments notes that “outsourcing credit card processing to a PCI-compliant third party can reduce scope and make it easier for universities to maintain compliance.”​
This is a highly effective strategy, especially for smaller campus departments that lack dedicated IT security staff.
Vendor due diligence is key here. Universities should require any payment-related service provider to show proof of PCI compliance (e.g. an Attestation of Compliance). Many schools even mandate that web payment pages or forms be hosted by a Level 1 PCI provider – for example, Harvard University’s policy states that any part of a payment page handling card data “must be hosted by a Level 1 PCI Compliant service provider.”​
Source: hcsra.sph.harvard.edu
This ensures that no card data touches an unvalidated environment. Common areas to use Level 1 vendors include payment gateways, cloud payment applications, credit card processors, and P2PE solution providers. When using such vendors, the university’s responsibility shifts to managing the relationship and ensuring the vendor maintains compliance (PCI DSS Requirement 12.8 covers monitoring service providers). Always keep an updated list of all third-party services that involve card data and confirm their PCI status annually. By partnering with top-tier compliant vendors, higher ed institutions can take advantage of expert security infrastructure and significantly lower the risk of a breach on campus. It’s a win-win: you offload heavy lifting to the experts, and focus your internal resources on the remaining areas under your direct control.
7. Establish Continuous Compliance and Monitoring
Lastly, universities should view PCI compliance as an ongoing program rather than a one-time project. This means instituting processes to continuously monitor your payment systems and compliance status throughout the year. Regularly review and update your PCI compliance policies and procedures – for example, ensure incident response plans are in place (PCI Requirement 12.10) and test them with drills. Perform periodic internal audits or readiness assessments ahead of the official yearly PCI validation to catch any lapses early. It’s wise to assign clear ownership of PCI compliance (e.g. a PCI compliance committee or a coordinator in the treasury or IT department) to drive these ongoing efforts.
Continuous monitoring includes keeping an eye on system logs, network traffic, and intrusion detection systems for any suspicious activity in the CDE. Setting up alerts for anomaly detection (like an unexpected device connecting to the payment network, or a surge in declined transactions) can give early warning of potential issues. Apply software patches and updates promptly to all systems in scope – unpatched vulnerabilities are a common cause of breaches. Ensure any new payment technology or project on campus goes through a PCI impact review before launch (for instance, if the athletics department wants a new mobile payment app, loop in the PCI team to assess compliance implications). As PCI DSS evolves (such as the transition to PCI DSS 4.0 by 2025, bringing new requirements and flexibility​), continuous adaptation is necessary. The mindset should be: PCI compliance is business-as-usual. This approach aligns with PCI 4.0’s push for “continuous compliance” rather than a yearly snapshot​.
Source: er.educause.edu
By embedding compliance into daily operations – from change management processes to new employee onboarding (include PCI in orientation training) – universities can avoid the scramble of annual assessments and be confident in their security year-round. In essence, make PCI compliance part of the campus culture, with leadership support and periodic reporting on compliance status to senior management. This sustained attention ensures that no requirement slips through the cracks and that the university’s payment systems remain secure against evolving threats.

Best Practices Quick Reference (Checklist)
For a concise overview, below is a checklist of PCI compliance best practices for university payment systems. University PCI teams can use this as a reference to ensure all critical areas are covered:
| Best Practice | Description/Action |
| Network Segmentation | Isolate the cardholder data environment (CDE) from the rest of campus networks. Use firewalls/VLANs to separate payment systems, limiting exposure of sensitive data. Test segmentation controls annually to ensure no crossover. |
| PCI-Validated P2PE | Deploy PCI-listed Point-to-Point Encryption so card data is encrypted at the point of capture. Encrypted data never touches university systems in plaintext, greatly reducing breach risk and PCI scope. |
| Vulnerability Scans & Pen Tests | Schedule quarterly vulnerability scans (internal & external) and annual penetration tests. Identify and remediate security gaps regularly. Include segmentation penetration testing for any isolated CDE networks. |
| Strict Access Controls | Limit access to payment systems on a need-to-know basis. Ensure unique user IDs for all staff, enforce strong passwords and multi-factor authentication, and promptly remove unused accounts. Monitor access logs for anomalies. |
| Annual PCI Training | Conduct PCI DSS and security awareness training at least once per year for all employees involved with payment processing. Emphasize safe handling of card data, phishing awareness, and incident reporting procedures. |
| Level 1 Compliant Vendors | Use third-party service providers who are Level 1 PCI DSS compliant for payment processing and storage. Outsource payment pages and card data functions to reduce on-campus handling of sensitive data (verify vendor compliance annually). |
| Scope Reduction Strategies | Aim to minimize systems and people that come into contact with card data. Use tokenization, outsourcing, and P2PE to keep card numbers off university systems. Fewer in-scope elements mean easier compliance management. |
| Continuous Monitoring | Implement continuous monitoring of security controls and network activity in the CDE. Keep software patched, review configurations, and perform periodic self-audits. Treat PCI compliance as an ongoing process, not a one-time event. |
By following the above checklist, universities can create a strong defensive posture and a streamlined compliance process. These best practices reinforce one another – for example, training staff supports better adherence to access controls, and using Level 1 vendors complements your network segmentation strategy. Together, they form a multi-layered approach to payment security on campus.
Case Study: How “State University” Improved Its PCI Posture (Fictional)
To illustrate these best practices in action, let’s consider a fictional example. State University, a mid-sized public institution, was struggling with PCI compliance. The university had over 25 departments handling payments, each with its own processes. An internal audit revealed several issues: too many computers had access to card data, some departments were using non-compliant payment applications, and staff awareness of security was low. State University’s CIO and Treasury Office decided to revamp their PCI compliance program using the strategies outlined above.
Initial Challenges: State U’s payment environment was sprawling. Every campus unit from the library to the athletics ticket office processed cards, meaning cardholder data was touching dozens of systems. They had little network separation – the bookstore’s payment terminals were on the same network as student computers. Training was ad-hoc, and there was no centralized oversight, leading to inconsistent practices. After a scare where a lost laptop containing some credit card spreadsheets fortunately did not result in a breach, leadership realized they were one incident away from disaster (and significant fines).
Steps Taken: The university formed a PCI Compliance Task Force including IT security, the campus treasurer, and key department managers. The task force executed a multi-pronged plan over 12 months:
- Scope Reduction & Segmentation: First, they identified every place card data was accepted. They eliminated obsolete or unnecessary payment points (some departments chose to stop handling cards entirely and routed payments through the central cashier instead). For the remaining ones, IT segmented the network – all payment devices and merchant applications were moved to a dedicated, firewalled network segment. For example, dining hall registers and the parking office card readers were put on a “Payment VLAN” isolated from academic networks. This immediately reduced risk and simplified compliance testing.
- P2PE and Secure Technologies: State U invested in a PCI-validated P2PE solution for all in-person payments. They replaced old card swipe terminals with new P2PE-enabled devices in the bookstore, dining, etc. Now, whenever a card was used on campus, the data was encrypted at swipe and no actual PAN (Primary Account Number) was stored on university systems. They also outsourced their online payments (tuition, donations, event ticketing) to a Level 1 PCI-compliant service provider. This meant web transactions were hosted on the provider’s secure platform, not on State U’s servers. With these changes, the university’s cardholder data environment shrank dramatically – most systems no longer handled raw card data at all.
- Policy and Access Control: The task force updated university policy to reflect strict PCI procedures. They instituted role-based access control for payment systems – only authorized treasury and IT staff could administer the payment servers, and department managers were limited to viewing their transactions. Unique logins were enforced everywhere and MFA was added to the remote management of payment systems. They also set up a procedure that any new payment technology or vendor had to be approved by the task force to ensure compliance from the start.
- Training and Awareness: A comprehensive training program was rolled out. All employees who handle credit cards (approximately 150 people across campus) attended a mandatory annual PCI compliance training session (with refreshers online). The training used relatable campus scenarios (like “What to do if a donor emails you their credit card number” and “How to spot a tampered card reader”). After training, employees demonstrated their knowledge via a short quiz. The university’s IT security team also began sending out quarterly cybersecurity newsletters with tips, keeping payment security on everyone’s radar.
- Ongoing Testing: State U contracted an Approved Scanning Vendor to conduct quarterly vulnerability scans on the in-scope systems (which were now mostly the payment network segment and a few servers). Initially, the scans found a couple of high-risk vulnerabilities – an out-of-date POS software version – which were promptly fixed. They also hired a security firm to perform an annual penetration test. In the first test, the firm attempted to breach the network from a student lab network; they were unable to penetrate the segmented payment network, validating the segmentation approach. The test did highlight a weakness in an outdated web payment form used by the library, which the university then migrated to the central online payment platform. This continuous improvement cycle became a new norm.
Results: One year later, State University’s PCI compliance posture was vastly improved. In their next PCI DSS assessment, they were able to use a shorter self-assessment (SAQ A for most departments that outsourced e-commerce, and SAQ P2PE for the card-present environments), making the process quicker and less costly. The number of systems in scope went down by 80%, and the university reduced its compliance management costs by an estimated 50% by consolidating vendors and systems. More importantly, their risk of breach plummeted – any would-be attacker breaching a campus network now would find almost no card data to steal, thanks to P2PE and tokenization. The staff felt more confident too; a follow-up phishing test resulted in a 60% reduction in clicks on a fake malicious email compared to before the training. The CIO reported to the board that State U had achieved full PCI compliance and was continuing with ongoing monitoring and improvements. The fictional State University’s journey shows that even a complex higher-ed environment can attain strong PCI compliance by applying best practices methodically: reduce scope, enforce security controls, educate people, and continuously verify.

Conclusion: Strengthening Security and Trust Through Best Practices
For university decision-makers, investing in PCI compliance best practices is not just about avoiding penalties – it’s about protecting the institution’s reputation, financial health, and the trust of your campus community. By implementing network segmentation, encryption (P2PE), rigorous testing, strict access control, staff training, and leveraging top-tier PCI-compliant vendors, universities create a multi-layered defense that significantly lowers the risk of a data breach. These measures also streamline the compliance process year after year, making annual audits or assessments far less painful to manage.
It’s important to remember that PCI compliance is an ongoing journey. Threats will continue to evolve, and the standards themselves (now PCI DSS 4.0) will adapt with new requirements and guidance.​
Source: arrowpayments.com
Higher education institutions should stay informed about updates from the PCI Security Standards Council and emerging trends in campus cybersecurity. Participation in higher-ed security forums (like Educause or the Treasury Institute’s PCI workshops) can provide valuable insights specific to university settings.
Above all, fostering a culture of security on campus is the best long-term strategy. When executives, IT teams, and departmental staff all embrace these best practices as part of their daily operations, compliance becomes second nature – “the way we do business” at the university. This proactive stance not only meets PCI DSS obligations but also positions the institution to handle other data security challenges with confidence. Colleges and universities are centers of innovation and learning; by applying that ethos to payment security, they can innovate in how they safeguard data and continuously learn from each security assessment to get even better.
In summary, PCI compliance best practices for universities boil down to: minimize what you must protect, lock down and watch over whatever is in your care, and educate the people involved. By following the roadmap and checklist provided here, higher education leaders can ensure their payment systems remain secure and compliant. This protects not just card data, but the broader mission of the institution by maintaining the trust of students, parents, alumni, and all stakeholders. With the right approach, universities can turn PCI compliance from a daunting task into a routine part of operational excellence in campus financial operations.
