Troy LeachApril 2012 The PCI Security Standards CouncilHello! My name is Troy Leach and I am the Chief Technology Officer of the PCI Security Standards Council.

First let me thank you for inviting me to speak with you today. What we are going to discuss today is important not only for your business, but for the entire global payment chain.

About the CouncilOpen, global forumFounded 2006Responsible for PCI Security StandardsDevelopmentManagementEducationAwareness2The PCI Security Standards Council is an open global forum, launched in September of 2006, for the ongoing development, enhancement, storage, dissemination and implementation of security standards for account data protection.

Very simply, this means that we want to protect not just consumers, but industry players such as merchants, processors, financial institutions, and other organizations that store, process and transmit cardholder data.

The Council is currently responsible for developing and evolving several standards we manage. One of my top priorities is to raise awareness of our standards globally by educating merchants, acquirers, processors and anyone else who stores, transmits or processes payment card data. These are the standards that will help you secure your data.ManufacturersPCI PTSPin Entry DevicesEcosystem of payment devices, applications, infrastructure and usersSoftware DevelopersPCI PA-DSSPayment ApplicationsPCI SecurityMOBILE PAYMENTSMerchants & Service ProvidersPCI DSSSecure EnvironmentsPCI Security StandardsProtection of Cardholder Payment Data3Many of you are already aware of the PCI Security Standards. We know that together these standards provide the best baseline protection for protecting payment account data in your organization.

This is a graphic representation of the suite of standards that we manage; PTS, PA-DSS, P2PE, and the PCI DSS.

As you can see now, it includes everything from point of entry of account data to how the data is processed through secure payment applications.

And most significant is the PCI DSS which is really a solid foundation for a defense in depth security strategy.

Areas of Focus for MobileDevicesTamper-resistance, Secure Card Readers, POI & P2PEApplicationsRequirements and/or Best Practices for authorization and settlementService ProvidersService provider protection of cardholder data and validationMOBILEPeripheral Device EncryptionThe mobile device is just a conduit. It has no ability to decrypt the encrypted data and therefore will never have access to clear-text account data.New PTS approval class for Secure (Encrypting) Card Readers (SCR)SCR and other POICardholder data is only input using an encrypted solution and transmitted encrypted through a mobile device.

Focused on identifying and clarifying the risks associated with accepting payments via mobile solutions and validating mobile payment acceptance applications to version 2.0 of the PA-DSS. Mobile Update Announcement and FAQ This is why we needed to clarify it and this is what we did to clarify itApplications eligible for PA-DSS are defined as:Those that store, process, or transmit cardholder data as part of authorization or settlement, andAre sold, licensed, or distributed to 3rd partiesClarification was needed - not all applications involved in payments transactions are eligible for PA-DSSThe Council received many questions about PA-DSS eligibilityPA-QSAs submitted PA-DSS reports for assessments of ineligible applications

Additional information on the Councils evaluation of mobile payment acceptance applications designed for communication devices may be found the PCI Security Standards Council Update on PA-DSS and Mobile Payment Acceptance Applications and accompanying FAQ. These resources provide guidance for vendors and merchants using mobile-based payment acceptance applications

The FAQ addresses a number of questions including - the defined categories of mobile payment acceptance solutions - the next steps for evaluating Category 3 applications Where do consumer-facing mobile payment applications and contactless technologies such as NFC fit into this classification And, additional guidance on what does this mean for merchants and vendors? 9Mobile Application CategoriesApplications for category 1 and 2 devices are eligible for PA-DSSApplications for category 3 devices pending development of further guidance and/or standardsCategory 2:Purpose Built POS DevicesCategory 3:General Purpose Smart DeviceCategory 1:PTS Approved PED DevicesMobile Working Group (MWG) Identified and clarified risks associated with accepting payments via mobile solutionsDetermined applicability of PA-DSS for validating mobile acceptance applicationsThree categories for mobile payment acceptance applications to address: The mobile application operating environmentThe ability of a mobile acceptance application to support merchant PCI DSS compliance

Mobile Payment Acceptance Application Category 1 Payment application operates only on a PTS-approved mobile device

Mobile Payment Acceptance Application Category 2 Payment application meets all of the following criteria; i. payment application is only provided as a complete solution bundled with a specific mobile device by the vendor; ii. underlying mobile device is purpose built (by design or by constraint) with a single function of performing payment acceptance; and iii. payment application, when installed on the bundled mobile device [as assessed by the Payment Application Qualifed Security Assessor (PA-QSA) and explicitly documented in the payment applications Report on Validation (ROV)], provides an environment which allows the merchant to meet and maintain PCI DSS compliance Bundled solutions are defined as the validated payment application being provided to the customer together with specific version(s) of both the mobile device and the devices operating system/firmware. Mobile Payment Acceptance Application Category3 Payment application operates on any consumer electronic handheld device (e.g., smart phone, tablet or PDA) that is not solely dedicated to payment acceptance for transaction processing

Application Security within Smart DevicesScenario 2: Guidance/best practices for protecting clear-text PAN within mobile applications Mobile Task Force commenced in JulyEvaluating potential guidance/best practices for mobile payment transactions where account data is input using a non-encrypted solution

Mobile Task Force To examine and provide guidance/best practices for mobile payment transactions for category 3 where account data is input using a non-encrypted solution.
