JSIR helps teams address PCI DSS 6.4.3 and 11.6.1 with automated script inventory, owner mapping, Dynamic SRI integrity monitoring, payment page change detection from the end-user browser, and evidence for QSA review.
Integration without heavy rework
Real-session monitoring
Webhooks to SOC/SIEM
Automated catalog of DOM scripts and third-party sources, including GTM and widgets, with owners, justification, and review status for 6.4.3.
Dynamic SRI support: hash and digital signature generation for static resources to reduce substitution risk and verify delivery integrity.
Comparison of HTML, JavaScript, and HTTP headers from the end-user browser against the approved baseline, with deviations recorded and notifications sent.
Exports for inventory, change logs, and check results. JSIR prepares practical evidence for QSA and internal audit reviews.
Client-side threat coverage
Web skimming, formjacking, and third-party script injections are captured as the customer's browser renders the page.
Low operational overhead
Sensors and crawlers are optimized for low conversion impact and predictable cost of ownership.
SOC/SIEM integration
Ready webhooks and SIEM log export can route events into SOC workflows and keep investigation artifacts reproducible.
| Task | Requirement | JSIR functions |
|---|---|---|
| Script and owner registry | 6.4.3 (a) | DOM, GTM, and widget catalog with roles and business justification |
| Integrity monitoring | 6.4.3 (b) | Dynamic SRI, signatures, and CDN delivery checks through CI/CD |
| End-user browser comparison | 11.6.1 | Browser-side HTML, JS, and header comparison against the baseline |
| Notification and response | 11.6.1 | Operational notifications, SIEM/SOC webhooks, response workflow |
| Audit artifacts | 4.0.1 | Export of comparisons, inventory, and logs for QSA or acquirer review |
PCI DSS 4.0.1 keeps the focus on payment page security and makes client-side script governance and change detection operationally important for e-commerce environments.
Requirement 6.4.3 expects organizations to manage scripts loaded and executed on payment pages, including authorization, business justification, and integrity controls.
Requirement 11.6.1 emphasizes change detection and response for payment pages, with notification to authorized personnel when unauthorized modifications are detected.
These changes reinforce continuous risk management for payment data security. Preparing the processes, controls, and evidence for 6.4.3 and 11.6.1 helps teams avoid late audit findings.
