The PCI Security Standards Council has published the PCI DSS Cloud Computing Guidelines Information Supplement, a product of the Cloud Special Interest Group (SIG).
The guide is an excellent introduction to the “cloud” and offers specific and helpful guidance on what to consider when processing payments involving the cloud as well as the storage of sensitive data.
One of cloud computing’s biggest strengths is its shared-responsibility model. However, this shared model can magnify the difficulties of architecting a secure computing environment,” said Chris Brenton, a PCI Cloud SIG contributor and director of security for CloudPassage. “One of this supplement’s greatest achievements is that it clearly defines the security responsibilities of the cloud provider and the cloud customer. With PCI DSS as the foundation, this guidance provides an excellent roadmap to crafting a secure posture in both private and public cloud.
The PCI DSS Cloud Computing Guidelines Information Supplement builds on the work of the 2011 Virtualization SIG, while leveraging other industry standards to provide guidance around the following primary areas and objectives:
- Cloud Overview – provides explanation of common deployment and service models for cloud environments, including how implementations may vary within the different types.
- Cloud Provider/Cloud Customer Relationships– outlines different roles and responsibilities across the different cloud models and guidance on how to determine and document these responsibilities.
- PCI DSS Considerations – provides guidance and examples to help determine responsibilities for individual PCI DSS requirements, and includes segmentation and scoping considerations.
- PCI DSS Compliance Challenges– describes some of the challenges associated with validating PCI DSS compliance in a cloud environment.
The document also includes a number of appendices to address specific PCI DSS requirements and implementation scenarios, including: additional considerations to help determine PCI DSS responsibilities across different cloud service models; sample system inventory for cloud computing environments; sample matrix for documenting how PCI DSS responsibilities are assigned between cloud provider and client; and a starting set of questions that can help in determining how PCI DSS requirements can be met in a particular cloud environment.
Merchants who use or are considering use of cloud technologies in their cardholder data environment and any third-party service providers that provide cloud services or cloud products for merchants can benefit from this guidance. This document may also be of value for assessors reviewing cloud environments as part of a PCI DSS assessment.
At the Council, we always talk about payment security as a shared responsibility. And cloud is by nature shared, which means that it’s increasingly important for all parties involved to understand their responsibility when it comes to protecting this data,” said Bob Russo, general manager, PCI Security Standards Council. “It’s great to see this guidance come to fruition, and we’re excited to get it into the hands of merchants and other organizations looking to take advantage of cloud technology in a secure manner.
