The landscape of digital transactions is constantly evolving, as are the associated threats. Responding to the dynamic nature of cybersecurity challenges, the Payment Card Industry Security Standards Council (PCI SSC) released v4.0 of the PCI Data Security Standard (PCI DSS) on March 31, 2022. This new iteration replaces version 3.2.1 and introduces several noteworthy changes and improvements to address emerging threats and technologies.
A Global Standard Evolving with Feedback
PCI DSS is a global standard establishing technical and operational criteria for safeguarding account data. The release of version 4.0 is a testament to the commitment of the PCI SSC to adapt to the ever-changing landscape of payment security. Over the past three years, feedback from more than 200 organizations worldwide has been incorporated, focusing on keeping the standard relevant in the complex realm of payment security.
Key Changes and Updates
1. Emphasis on Continuous Security
PCI DSS v4.0 places a strong emphasis on security as a continuous process. The updates aim to meet the evolving security needs of the payment industry, encouraging organizations to view security not as a one-time compliance requirement but as an ongoing commitment. This is reflected in more stringent requirements for multi-factor authentication (MFA) and updated password standards.
2. New Requirements and Guidance
The latest version introduces new requirements and assigns specific roles and responsibilities for each one. This provides clarity on how organizations should implement and maintain security measures. Additionally, PCI DSS v4.0 incorporates guidance to assist individuals in better understanding the implementation of security controls.
3. Enhanced Flexibility for Organizations
Recognizing the diverse methods organizations employ to achieve their security goals, PCI DSS v4.0 introduces new options to enhance flexibility. This includes permissions for group, shared, and public accounts and targeted risk analyses to help organizations determine the frequency of certain security activities. A customized approach is also introduced, providing innovative methods for organizations to meet PCI DSS requirements.
4. Improved Verification and Reporting
Detailed reporting options have been developed to enhance verification methods and procedures. This ensures increased congruence between information reported in Compliance Reports or Self-Assessment Questionnaires and the information summarized in the Attestation of Compliance.
Transition Period and Implementation
After the launch of PCI DSS v4.0, organizations have a two-year transition period, lasting until March 31, 2024. During this time, PCI DSS v3.2.1 remains operational, allowing organizations to familiarize themselves with the changes, update reporting templates, and plan and implement necessary adjustments. Assessors can choose to undertake assessments using either version after completing PCI DSS v4.0 training.
Organizations must understand that new best practice requirements identified in PCI DSS v4.0 must be fully implemented by March 31, 2025. Until then, compliance is not mandatory, but organizations prepared to meet these new requirements can audit through them.
Summary of Control Requirements
PCI DSS version 4.0 consists of 12 requirements and three additional Appendices. Altogether, there are 280 individual controls specified across the 12 requirements and three appendices.

Requirement 3: Protect Stored Account Data
While not focused on data encryption, CimTrak's FIM functionality promptly detects unauthorized changes or access to files storing sensitive data.
Requirement 4: Protect Cardholder Data with Strong Cryptography During Transmission Over Open, Public Networks
CimTrak's FIM can monitor and alert on configuration changes or software managing data transmissions, ensuring cardholder data security during transmission.
Maintain a Vulnerability Management Program
Requirement 5: Protect All Systems and Networks from Malicious Software
CimTrak's FIM detects changes caused by malicious software, facilitating rapid response to potential threats. It monitors critical system files to ensure they remain unaltered and uncompromised.
Requirement 6: Develop and Maintain Secure Systems and Software
CimTrak's FIM module monitors files, registries, databases, and more, providing real-time identification of system changes. Its continuous configuration audit ensures compliance with secure configurations and hardening standards.
Implement Strong Access Control Measures
Requirement 7: Restrict Access to System Components and Cardholder Data by Business Need to Know
CimTrak monitors access and changes to files, alerting on unauthorized access or modifications. 'Monitor Reads' mode creates an audit trail of all file access.
Requirement 8: Identify Users and Authenticate Access to System Components
CimTrak's monitoring capabilities track changes to authentication configurations, ensuring robust identity and access controls.
Regularly Monitor and Test Networks
Requirement 10: Log and Monitor All Access to System Components and Cardholder Data
CimTrak establishes an authoritative baseline, providing robust monitoring and logging of all access and changes to system components for a comprehensive audit trail.
Requirement 11: Test Security of Systems and Networks Regularly
CimTrak provides continuous audits and assessments to determine if systems comply with PCI DSS and other security standards.
Maintain an Information Security Policy
Requirement 12: Support Information Security with Organizational Policies and Programs
CimTrak supports policy enforcement by monitoring systems for compliance and detecting deviations from established security policies.
Appendix A Additional PCI DSS Requirements
