As the lead security engineer for a retail corporation, you are assessing the security of the wireless networks in the company's stores. One of your main concerns is the potential for "Wardriving"…
The correct answer is A. Limit the range of the store's wireless signals. To mitigate the risk of Wardriving without impacting customer Wi-Fi experience in a retail store, limiting the range of the store's wireless signals is the most suitable measure.

Why each option
To mitigate the risk of Wardriving without impacting customer Wi-Fi experience in a retail store, limiting the range of the store's wireless signals is the most suitable measure.
Wardriving involves discovering wireless networks from outside the physical premises. By reducing the transmission power of the wireless access points, the signal strength and reach can be confined primarily to the store's interior. This makes it significantly more difficult for attackers outside the building to detect and map the network, thereby directly mitigating wardriving without affecting legitimate in-store customer access.
MAC address filtering is easily bypassed by MAC spoofing and creates significant management overhead for legitimate customer devices, thus interfering with the customer experience.
Disabling SSID broadcasting offers minimal security as the SSID can still be discovered with sniffing tools, and it complicates legitimate customer access, negatively impacting the user experience.
Implementing WPA3 encryption secures access to the network once found, but it does not prevent the network's existence from being detected from outside the premises, which is the core concern for Wardriving.
