Which PCI DSS requirement addresses ensuring current network diagrams identify all connections between the cardholder data environment and other networks, including wireless networks?

• A. Requirement 1.1
• B. Requirement 1.1.1
• C. Requirement 1.1.2
• D. Requirement 2.1

Answer: (C)

Maintaining a current network diagram that shows every connection between the cardholder data environment and other networks (including wireless) is all about clearly mapping the boundaries where data moves. This requirement ensures you can see every path cardholder data could travel, so you can enforce proper segmentation and apply firewall controls to every route. By having an up-to-date diagram, you can identify and manage all entry points and ensure wireless networks, remote connections, and partner links are accounted for and protected. Other aspects of firewall setup or security policies are important, but they don’t by themselves mandate keeping that complete, up-to-date map of network connections. The diagram provides the concrete, ongoing visibility that underpins effective boundary protection and change management, making it the best fit for this requirement.
