PCI v1.1 Primer: How Does PCI Apply to Wireless LANs?
03/09/2007
The increasing adoption of WLANs creates a new set of security threats and vulnerabilities to networks in retail stores that carry credit card data. To this end, PCI DSS v1.1 provides specific security requirements for different wireless LAN applications -- from wireless in-store inventory applications to applications such as wireless Point-Of-Sale that wirelessly transmit payment card information. There are even requirements for retailers that do not operate wireless LANs, but may come in contact with them in ways that could impact the security of the retailer's connection to the credit card processing network. This paper describes the requirements and solutions for all requirements that relate to wireless LANs in the new PCI DSS v1.1.
