Which statement best describes PA-DSS in the context of payment software?

• A. To secure payment application software
• B. To secure the network perimeter
• C. To enforce password policies
• D. To govern payment application software security standards

Answer: (A)

PA-DSS focuses on the payment application software itself—the programs merchants use to process card payments. It sets requirements for how the software is designed, developed, and implemented so that it securely handles cardholder data, minimizes opportunities to expose data, and can be used safely within the payment ecosystem. This means ensuring the app stores, processes, and transmits data in ways that protect card information and that it ships with secure defaults and appropriate data handling practices. It’s not about securing the network perimeter, enforcing password policies across systems, or governing security standards in a broad sense. Those areas are addressed by other PCI controls and governance. So, the statement that PA-DSS is about securing payment application software best captures its purpose.
