The transition to PCI DSS v4.0 introduces a more rigorous, unified framework for protecting cardholder data (CHD) and sensitive authentication data (SAD). As attack surfaces expand, this checklist provides a practical roadmap to evaluate your 12 core requirements, identify root causes of non-compliance, and define critical corrective actions.
What You Will Learn
Network Security & Segmentation:
How to define CDE boundaries and validate segmentation to isolate cardholder data from out-of-scope networks.
Data Protection Standards:
Implementing strong cryptography (e.g., AES-256) and tokenization to render Primary Account Numbers (PAN) unreadable.
Modern Authentication Requirements:
Enforcing Phishing-resistant Multi-Factor Authentication (MFA) for all administrative and remote access into the CDE.
Continuous Compliance Monitoring:
Establishing a "PCI Compliance Calendar" to automate evidence capture and ensure controls remain effective year-round
