Payment Card Industry (PCI) Data Security Standard (DSS)

PCI DSS overview

The Payment Card Industry (PCI) Data Security Standards (DSS) is a global information security standard designed to prevent fraud through increased control of credit card data. Organizations of all sizes must follow PCI DSS standards if they accept payment cards from the five major credit card brands — Visa, MasterCard, American Express, Discover, and the Japan Credit Bureau (JCB). Compliance with PCI DSS is required for any organization that stores, processes, or transmits payment and cardholder data.

Microsoft and PCI DSS

Microsoft completed an annual PCI DSS assessment using an approved Qualified Security Assessor (QSA). The auditors reviewed Microsoft Azure, Microsoft OneDrive for Business, and Microsoft SharePoint Online environments, which include validating the infrastructure, development, operations, management, support, and in-scope services. The PCI DSS designates four levels of compliance based on transaction volume. Azure, OneDrive for Business, and SharePoint Online are certified as compliant under PCI DSS version 3.2 at Service Provider Level 1 (the highest volume of transactions — more than 6 million a year).

The assessment results in an Attestation of Compliance (AoC), which is available to customers and Report on Compliance (RoC) issued by the QSA. The effective period for compliance begins upon passing the audit and receiving the AoC from the assessor and ends one year from the date the AoC is signed.

Customers who want to develop a cardholder environment or card processing service can use these validations in many of the underlying portions, thereby reducing the associated effort and costs of getting their own PCI DSS certification.

It is important to understand that PCI DSS compliance status for Azure, OneDrive for Business, and SharePoint Online not automatically translate to PCI DSS certification for the services that customers build or host on these platforms. Customers are responsible for ensuring that they achieve compliance with PCI DSS requirements.

Frequently asked questions

Why does the Attestation of Compliance (AoC) cover page say “June 2018”?

The June 2018 date on the cover page is when the AoC template was published. Refer to Section 2 for the date of the assessment.

Why are there multiple Azure Attestations of Compliance (AoCs)?

The Azure AoC package has AoCs corresponding to Azure Public, Germany, and Government cloud. Customers should use the AoC that corresponds with their Azure environment.

What is the relationship between the PA DSS and PCI DSS?

The Payment Application Data Security Standard (PA DSS) is a set of requirements that comply with the PCI DSS, and replaces Visa’s Payment Application Best Practices, and consolidates the compliance requirements of the other primary card issuers. The PA DSS helps software vendors develop third-party applications that store, process, or transmit cardholder payment data as part of a card authorization or settlement process. Retailers must use PA DSS certified applications to efficiently achieve their PCI DSS compliance. The PA DSS does not apply to Azure.

What is an acquirer and does Azure use one?

An acquirer is a bank or other entity that processes payment card transactions. Azure does not offer payment card processing as a service and thus does not use an acquirer.

To what organizations and merchants does the PCI DSS apply?

PCI DSS applies to any company, no matter the size, or number of transactions, that accepts, transmits, or stores cardholder data. That is, if any customer ever pays a company using a credit or debit card, then the PCI DSS requirements apply. Companies are validated at one of four levels based on the total transaction volume over a 12-month period. Level 1 is for companies that process over 6 million transactions a year; Level 2 for 1 million to 6 million transactions; Level 3 is for 20,000 to 1 million transactions; and Level 4 is for fewer than 20,000 transactions.

Where do I begin my organization’s PCI DSS compliance efforts for a solution deployed on Azure?

The information that the PCI Security Standards Council makes available is a good place to learn about specific compliance requirements. The council publishes the PCI DSS Quick Reference Guide for merchants and others involved in payment card processing. The guide explains how the PCI DSS can help protect a payment card transaction environment and how to apply it.

Compliance involves several factors, including assessing the systems and processes not hosted on Azure. Individual requirements vary based on which Azure services are used and how they are employed within the solution.

Are there plans for OneDrive for Business and SharePoint Online to be PCI DSS-compliant outside of the United States?

Currently OneDrive for Business and SharePoint Online is PCI-DSS compliant only in the United States (US). Microsoft will evaluate the requirements and timelines for regions outside of US and provide updates when and if other regions are added to the roadmap.

What is in-scope for OneDrive for Business and SharePoint Online?

Currently, only files and documents uploaded to OneDrive for Business and SharePoint Online will be complaint with PCI DSS.
