Enhanced Checkout with Shopify

Introduction

Keeping up with trade compliance requirements is a complex challenge. The introduction of new regulations, such as the anti-skimming protections of version 4 of the Payment Card Industry Data Security Standard (PCI DSS), has significant implications for merchants. Fortunately, stores upgrading to Shopify's Checkout Extensibility benefit from an advanced architecture that makes PCI DSS v4 compliance simple and straightforward.

Sandboxing: Future-Proofing Shopify's Checkout Architecture

Offering a fast, secure, and compliant checkout experience is a daunting task. Shopify simplifies this process through an innovative architecture that combines a robust backend and a customizable frontend. The backend, hosted on Shopify's servers, is designed to handle large-scale sales, while the frontend allows for customization through Shopify-managed extensibility.

Safety and Performance

Security is a top priority for Shopify. Using web sandboxing technologies, Shopify runs app-provided code in isolated JavaScript environments, communicating with the main page via a mediated bridge. This approach ensures that potentially untrusted code is isolated, keeping the checkout responsive and secure.

Upgradeability and Compliance

Sandboxing allows Shopify to update and maintain the platform without breaking extensions or web pixels. UI extensions and web pixels are implemented based on the API, providing protection from future updates. Additionally, Shopify ensures compliance with PCI DSS v4 regulations without requiring additional action from merchants.

PCI DSS v4 Requirements

PCI DSS version 4 introduces new requirements to ensure transaction security. These include maintaining an inventory of all scripts, ensuring only authorized scripts are loaded, and verifying the integrity of each loaded script. These requirements apply to both the main and payment pages, providing stronger anti-skimming protection.

Shopify Solutions for PCI DSS v4 Compliance

Shopify offers a number of solutions to ensure compliance with the new standards:

- Review and Review Dependencies: Shopify reviews all third-party dependencies used on the main page.
- Regular Script Updates: Regular updates are performed to incorporate the latest security patches.
- Change Management: Shopify maintains a rigorous change management process with approved reviews and testing.
- Content Security Policy (CSP): Use CSP to allow only authorized scripts and report any violations.
- Subresource Integrity (SRI): Ensures the integrity of loaded scripts.
- Payment Form Isolation: The payment form is loaded and isolated via iframe for added security.

Conclusion

Shopify's proactive approach to PCI DSS v4 compliance allows merchants to focus on growing their business without worrying about technical complications. Thanks to the protections provided by the managed runtime, merchants can continue to customize their checkout with confidence.
