PCI DSS 4.0.1 Compliance Automation
Continuous vulnerability scanning and automated evidence collection for PCI DSS 4.0.1.
What is PCI DSS 4.0.1?
PCI DSS 4.0.1 is the Payment Card Industry Data Security Standard for organisations that store, process, or transmit account data. Requirements 6.4.3 and 11.6.1 specifically address browser-delivered payment pages: merchants must manage and justify every script, assure script integrity, and deploy a change- and tamper-detection mechanism that evaluates payment pages and security-impacting HTTP headers at least weekly or at a frequency defined by targeted risk analysis.
How DygDog Maps to PCI DSS 4.0.1 Controls
DygDog builds a sanitised inventory of first- and third-party scripts, records integrity and crossorigin metadata, evaluates the effective Content Security Policy, and compares each scan with the latest tenant-isolated baseline. Findings map directly to Requirement 6.4.3 for script authorisation, justification, inventory, and integrity assurance, and Requirement 11.6.1 for payment-page change detection. DygDog provides external monitoring evidence; it does not by itself establish full PCI DSS compliance or replace a Qualified Security Assessor.
Key PCI DSS 4.0.1 Requirements Addressed
- Authorise and maintain an inventory of every payment-page script (6.4.3)
- Document why each script is necessary (6.4.3)
- Assure the integrity of payment-page scripts (6.4.3)
- Detect unauthorised changes to payment pages and security-impacting headers (11.6.1)
- Evaluate changes at least weekly or at the frequency established by targeted risk analysis (11.6.1)
Audit Readiness
Each Pro deep scan preserves a timestamped script inventory, aggregate fingerprint, page classification, CSP/SRI summary, and any added, removed, or changed scripts. Running this monitor at least weekly creates reviewable evidence for change detection, while unexplained payment-page drift is elevated for immediate investigation. Your organisation remains responsible for documenting script business justification, approval, response procedures, and the scanning frequency required by its targeted risk analysis.
