Which PCI DSS requirement is about establishing and implementing firewall and router configuration standards?

• A. Requirement 1.1
• B. Requirement 2.1
• C. Requirement 4
• D. Requirement 6

Answer: (A)

The concept being tested is identifying the PCI DSS requirement that governs setting and enforcing firewall and router configuration standards to protect the cardholder data environment. This focus is exactly what the firewall configuration requirement asks for—establishing and maintaining a documented standard for how network devices like firewalls and routers control traffic into and out of the cardholder data environment, ensuring only authorized connections are allowed and that segmentation is in place. Why the chosen option fits best: it directly addresses creating and maintaining firewall configurations to protect cardholder data, which is the core purpose of that requirement—to define rules, enforce them, and keep the network boundary secure. The other options don’t fit as well: one highlights avoiding vendor defaults (a hardening topic, not specifically about firewall configurations), another centers on encrypting data in transit (protection after traffic is allowed, not about establishing the traffic-control standards), and the last focuses on secure software development and patching (a separate area of security).
