PCI DSS 4.1.2: Assign Transmission Protection Roles & Responsibilities
Effective transmission protection requires clear ownership and accountability. PCI DSS 4.1.2 mandates that organizations document, assign, and communicate roles and responsibilities for all Requirement 4 activities to prevent unauthorized data exposure during cardholder information transmission.
What this means
This control requires you to create and maintain formal documentation that defines who is responsible for transmission protection activities within your organization.
