Demystifying PCI DSS 4.0: The Ultimate Guide to Protecting Your Business from Cyber Attacks!
PCI DSS (Payment Card Industry Data Security Standard) compliance is a set of security standards with which organizations who handle payment card data must comply. The purpose of these standards is to ensure that sensitive information like credit card numbers and personal data are protected from unauthorized access and theft.
The latest update to PCI DSS Standards, version 4.0, was released March 2022 by the PCI Security Standards Council (PCI DSS 4.0). This most recent version of the standard took four years to create and grew from 139 pages for PCI v3.2.1 to 360 pages for PCI v4.0. 64 additional requirements are present, 13 of which take effect in March 2024, when PCI DSS v3.2.1 is formally decommissioned. The remaining 54 requirements are “best practices” until March 2025. That doesn’t mean you can sit back and enjoy your current compliance status for the next 2 years. On the contrary, 2023 must be used as a transition period to assess the new standard and modernize your security controls. There is a lot of work to do and very little time. Do not assume because you are PCI 3.2.1 compliant that you will be PCI 4.0 compliant.
Failing to Comply
Failing to comply with these standards results in serious consequences for businesses. In this article, we detail the consequences of failing PCI DSS compliance and the steps businesses can take to avoid it.
Penalties and Fines
The most immediate consequence of failing PCI DSS compliance is the possibility of penalties and fines. The payment card industry takes data security very seriously, and non-compliance can result in significant fines that can range from thousands to millions of dollars, depending on the severity of the breach. These fines are usually imposed by the payment card brands, such as Visa, Mastercard, and American Express. Failure to pay these fines can make it difficult or impossible to process credit card transactions.
Failure to comply with the PCI DSS increases an organization’s legal liability in the event of a data breach and the offender may be held liable for the resulting damages and costs. This can include the cost of notifying affected customers, offering credit monitoring services, and paying legal fees. Furthermore, noncompliance increases the likelihood of regulatory investigations, which can result in additional fines, penalties, and legal fees.
The Catastrophic Cost of Non Compliance
Achieving and maintaining PCI DSS compliance is an added cost for businesses, but failure to comply can result in catastrophically higher costs. Fines, penalties, legal fees, and the cost of implementing new security measures to address vulnerabilities can all be incurred as a result of noncompliance. Furthermore, noncompliance raises the cost of doing business through lost revenue, reputational damage, and decreased customer loyalty.
A data breach can have serious consequences for an organization’s reputation. Consumers rely on businesses to safeguard their sensitive information, and failing to do so leads to a loss of trust and confidence. This lack of trust means decreased consumer loyalty, income, and damaged brand reputation. Even without a breach, the perception of a lack of security is damaging to a company’s brand.
Loss of Customers
Consumers have a choice about where they do business, and a breach impacts trust in an organization’s capacity to protect their sensitive information. This leads to a drop in consumer loyalty and a loss of revenue. It can take years to rebuild trust and confidence – devastating for most businesses.
How to Avoid PCI DSS Compliance Failure
Achieving and maintaining PCI DSS compliance requires a commitment to data security and ongoing efforts to stay up to date with evolving security threats. Compliance is typically a process that looks backward. The purpose of compliance requirements is to stop problems from happening again in the future. PCI DSS 4.0 has changed this. The 4.0 standard has been updated to take into account the use of emerging technologies and the changing threat landscape. It was created with a ZERO Trust strategy to meet the evolving needs of the payments industry. PCI DSS 4.0 enables organizations with a mature security posture the freedom to design and implement controls that achieve the goals. This modernized approach means compliance is now an ongoing, REAL-TIME process that depends on dynamic security measures and the proof of those measures rather than a one-time event.
Here are some steps businesses can take to avoid PCI DSS compliance failure:
Read and Understand the Standard
The first step to avoiding PCI DSS compliance failure is to understand the requirements and what they mean to your organization. The standards cover a broad range of security measures, including firewalls, encryption, access controls, monitoring and regular security testing. By understanding the requirements, you can identify areas where your organization may be falling short and take action to address any gaps.

Additionally, we assess and address potential vulnerabilities in your systems.
Strong Security Controls and Monitoring
For sensitive cardholder data to be protected, proper access controls are crucial. It is essential to ensure that all the required security configurations are in place to restrict access to cardholder data. Implementing strong access controls means only authorized individuals with permission can access sensitive data. One effective measure is to enforce strong password policies, requiring users to create complex and unique passwords coupled with multi-factor authentication that requires a second form of verification, such as a unique code sent to a registered device, further mitigating the risk of unauthorized access. XYPRO solutions, specifically designed for NonStop systems, assist in implementing and managing these access control measures effectively.
In addition to enforcing access controls, it is crucial to actively monitor for configuration drift and non-compliance. Conducting regular risk assessments identifies potential security threats and vulnerabilities. By proactively assessing the environment, you stay ahead of potential issues and take steps to address them before they escalate into significant problems.This approach helps identify and resolve security gaps, minimizing the risk of non-compliance and data breaches.
Monitoring user activity and access to sensitive data is a vital component of maintaining PCI DSS compliance. Access should be consistently monitored and reviewed to identify and prevent any unauthorized access attempts. Real-time monitoring detects suspicious activities or unusual patterns that may indicate a potential breach or unauthorized access. For HPE NonStop systems, XYGATE SecurityOne tracks and analyzes access logs, to promptly investigate any anomalies and take appropriate action. Monitoring access ensures that only authorized individuals are accessing cardholder data, reducing the risk of data breaches and non-compliance.
Maintain Evidence and Documentation
Maintaining thorough documentation supports transparency, accountability, and the capacity to manage and maintain PCI DSS compliance effectively. Documentation is a comprehensive record of the security measures and procedures implemented by an organization to safeguard cardholder data. It serves as evidence that the required controls and processes are in place and facilitates compliance demonstrations during audits and assessments. Documentation also facilitates the monitoring and tracking of changes, ensuring that security controls remain current and aligned with the evolving threat landscape. It serves as a reference for future evaluations and helps identify improvement areas.
Well-documented procedures and evidence aid forensic investigations, facilitate incident response, and demonstrate due diligence in protecting cardholder data in the event of a security breach or incident. For NonStop systems, the XYGATE SecurityOne Suite provides all the necessary components to generate the data, evidence and reports necessary to maintain proper documentation that will be accepted by PCI auditors.
