Along with industry colleagues, Mastercard founded and developed the Payment Card Industry Data Security Standard (PCI DSS) in 2006. To help customers, merchants and service providers comply with this critical standard, Mastercard also offers the Site Data Protection (SDP) Program.
The SDP Program, with the PCI DSS as its foundation, details the data security and compliance validation requirements necessary to protect stored and transmitted Mastercard payment account data.
The PCI DSS is designed to identify vulnerabilities in security processes, procedures and website configurations. PCI DSS compliance and subsequent compliance with the SDP Program mandate, helps customers, merchants and service providers protect themselves against security breaches, while enhancing consumer confidence and protecting the overall integrity of the payment system.
The PCI Data Security Standard
With over 250 sub-requirements, the PCI DSS can be sorted at a high level into six goals and 12 main requirements.
Six Goals, 12 Requirements
|Goals||PCI DSS Requirements|
|Build and Maintain
a Secure Network and Systems
|1: Install and maintain a firewall configuration to protect cardholder data
2: Do not use vendor-supplied defaults for system passwords and other security parameters
|Protect Cardholder Data||3: Protect stored cardholder data
4: Encrypt transmissions of cardholder data across open, public networks
|Maintain a Vulnerability Management Program||5: Protect all systems against malware and regularly update anti-virus software or programs
6: Develop and maintain secure systems and applications
|Implement Strong Access
|7: Restrict access to cardholder data by business need-to-know
8: Identify and authenticate access to system components
9: Restrict physical access to cardholder data
and Test Networks
|10: Track and monitor all access to network resources and cardholder data
11: Regularly test security systems and processes
|Maintain an Information
|12: Maintain a policy that addresses information security for all personnel|
Payment application data security standard
The Payment Application Data Security Standard (PA-DSS) is for software developers and integrators of payment applications that store, process or transmit cardholder data as part of authorization or settlement when these applications are sold, distributed or licensed to third parties.
PA-DSS requires vendors of third-party payment applications to ensure proper security controls are in place to safeguard cardholder data. Many of the controls within PA-DSS are designed to specifically address common vulnerabilities that were identified as main causes in credit card data loss.
Mastercard PA-DSS mandate
Mastercard requires all merchants and service providers that use third party-provided payment applications to only use those applications that are compliant with the Payment Card Industry Payment Application Data Security Standard (PCI PA-DSS), as applicable. The applicability of the PCI PA-DSS to third party-provided payment applications is defined in the PCI PA-DSS Program Guide available on the PCI Security Standards Council (SSC) website.
Mastercard also recommends that merchants use a Qualified Integrator & Reseller (QIR) listed on the PCI SSC website to implement a PCI PA-DSS-compliant payment application.
