You are working for an IT consulting firm and have been tasked with setting up several SOHO wireless networks. Which of the following actions will best help protect the confidentiality of data transmitted over the wireless network?
Enabling modern wireless encryption (such as WPA2 or WPA3) scrambles every frame with strong cryptography, so intercepted traffic cannot be read without the key. Simply lowering the access point's transmit power, hiding or disabling the SSID broadcast, or enabling MAC address filtering may deter casual users, but they do not encrypt traffic and can be bypassed with freely available tools.
