2025 PCI Compliance Checklist

In today’s rapidly evolving cybersecurity landscape, achieving and maintaining PCI compliance is more critical than ever. With the latest update to PCI DSS 4.0.1, businesses must adapt to meet new standards designed to enhance security and flexibility. This updated PCI Compliance Checklist outlines the essential steps for staying compliant while optimizing your organization’s security posture. 
 

What Is PCI DSS Compliance? 

PCI DSS (Payment Card Industry Data Security Standard) is a set of security requirements designed to protect cardholder data. Compliance is mandatory for businesses that process, store, or transmit credit card information. Non-compliance can result in hefty fines, reputational damage, and increased vulnerability to cyberattacks. 

Key Updates in PCI DSS 4.0.1 

Enhanced Security Requirements:

• Increased focus on risk-based approaches. 
• Strengthened authentication requirements, including multi-factor authentication (MFA) for all access to the cardholder data environment. 

Flexibility in Implementation:

• Customized implementation options allow organizations to meet security objectives using alternative methods tailored to their specific environments. 

Annual Scope Review:

• Organizations must annually review and document the scope of their cardholder data environments to ensure all components are adequately protected. 

Expanded Requirements:

• The total number of requirements increased to over 600, emphasizing continuous monitoring and automated security solutions. 

Updated Reporting and Documentation:

• Enhanced reporting templates now include additional details about customized implementations and specific requirements regarding the frequency of testing for controls, ensuring alignment with PCI DSS 4.0.1 standards.   

The 2025 PCI Compliance Checklist 

1. Understand the PCI DSS 4.0.1 Requirements

   1. Review the latest PCI DSS documentation. 
   2. Identify which requirements apply to your organization based on your role in storing, processing or transmitting cardholder data. 
   3. Highlight which of the new requirements are applicable to your organization. Assess if you have these in place and determine how to start implementing controls where necessary. 

2. Define Your Cardholder Data Environment (CDE)

   1. Map out all systems, networks, and devices that interact with cardholder data. 
   2. Use segmentation to isolate the CDE and reduce the scope of compliance. 

3. Review PCI 4.0.1 Requirements

   1. Required after March 31, 2025.  Companies must fully comply with new requirements by this date. 

4. Implement Strong Access Controls

   1. Enforce MFA for all access to systems within the CDE. 
   2. Use role-based access controls to limit privileges to only what’s necessary. 

5. Maintain Secure Network Systems

   1. Regularly update firewalls, routers, and other critical infrastructure. 
   2. Use intrusion detection and prevention systems (IDS/IPS) to monitor or block malicious activity. 

6. Encrypt Cardholder Data

   1. Ensure all stored cardholder data is encrypted using strong cryptography. 
   2. Use Transport Layer Security (TLS) for secure data transmission. 

7. Conduct Regular Vulnerability Scans and Penetration Testing

   1. Perform quarterly vulnerability scans and annual penetration tests. 
   2. Service providers leveraging segmentation must perform additional segmentation tests every 6 months.  
   3. Address any identified vulnerabilities promptly per vulnerability management standards. 

8. Monitor and Log All Activities

   1. Implement logging mechanisms to track access and changes to critical systems. 
   2. Retain logs for at least one year, with three months readily accessible for review. 

9. Train Employees on Security Best Practices

   1. Provide ongoing training to ensure employees and system administrators understand their role in protecting cardholder data. 
   2. Conduct simulated phishing tests and other awareness exercises. 

10. Engage a Qualified Security Assessor (QSA)

    1. Work with a QSA to validate compliance and identify areas for improvement. 
    2. Use their expertise to streamline the assessment process. 

11. Document and Maintain Compliance Efforts

    1. Keep detailed records of all compliance-related activities, including policies, procedures, change management, and technical implementations. 
    2. Conduct periodic reviews to ensure continued adherence to PCI DSS requirements. Service providers specifically must perform this quarterly per PCI DSS standards.
