Security, privacy, and trust converge across five control pillars of PCI 3DS compliance.
Establish governance structures to enforce policies, responsibilities, and risk-driven oversight mechanisms.




Data protection and cryptographic controls are central pillars of PCI 3DS security compliance.
Sensitive data must be encrypted when stored to prevent unauthorized access or tampering.
Data moving across networks requires strong cryptographic safeguards to ensure confidentiality and integrity.
Robust key lifecycle procedures prevent misuse, compromise, or accidental exposure of cryptographic material.
Clearly defined categories guide how different data types should be protected and handled.
Track system activity to detect anomalies, prevent breaches, and ensure PCI 3DS accountability.
Logs must be stored securely and retained per compliance mandates and audit needs.
Mechanisms must ensure log integrity—no unauthorized modifications, ever.
Only authorized personnel may view, modify, or manage sensitive log files.
Systems must record who did what, when, and from where.
Implement tools to detect and alert suspicious or unauthorized activity instantly.
