Who is ultimately responsible for the protection of cardholder data and PCI DSS compliance programs?

The ultimate responsibility for the protection of cardholder data and ensuring compliance with the Payment Card Industry Data Security Standard (PCI DSS) lies with Executive Management. This is because executive management sets the tone for data security culture within an organization and has the authority to allocate resources, influence policies, and enforce compliance measures. Their leadership is essential in ensuring that a robust framework for data protection is established and maintained.

While other roles, such as the IT Department, Chief Financial Officer, and Data Protection Officer, play significant parts in implementing and managing security measures and policies, they do so under the direction and oversight of Executive Management. This leadership role encompasses accountability for compliance, risk management, and strategic decision-making that directly impacts how cardholder data is protected. Therefore, it is crucial for executive leadership to actively engage in developing and supporting the organization's PCI DSS compliance program to protect sensitive cardholder information effectively.
