Meeting PCI DSS 4.0 as a Payment Processor

Payment processors face unique challenges under PCI DSS 4.0. Your iFrames must prevent unauthorized code execution while hosted on merchant websites, requiring continuous monitoring and protection of scripts during actual payment processing.

Illustration of PCI DSS 6.4.3 compliance, ensuring complete script inventory, documentation, and security justification for payment pages.

Payment Page Script Requirements

Requirement 6.4.3 mandates managing all scripts across payment pages and iFrames. Payment processors must inventory scripts, ensure integrity, and prevent unauthorized code execution as iFrames render in customer browsers – even when embedded on merchant sites.

Payment iFrame Protection

Your embedded payment iFrames must maintain integrity across thousands of merchant websites. Requirement 11.6.1 requires detecting and responding to tampering attempts in real-time during actual payment processing.

Script Management at Scale

As a payment processor, you must catalog and protect scripts across millions of transactions. This includes managing script integrity, detecting tampering, and preventing unauthorized code execution – all while maintaining processing efficiency.

Continuous Compliance Evidence

Payment processors must demonstrate continuous compliance for PCI assessments. This requires documenting script controls, monitoring unauthorized changes, and maintaining evidence of runtime protection during payment processing.
