You are a cybersecurity trainee tasked with securing a small home network. The homeowner is concerned about potential "Wi-Fi eavesdropping," where unauthorized individuals could intercept the…

Disabling the SSID broadcast only hides the network name from casual discovery but does not prevent determined attackers from finding the network or intercepting its traffic once connected or identified.

Enabling strong encryption, such as WPA2 or WPA3, on a wireless network scrambles the data transmitted between devices and the router. This mechanism ensures that even if an unauthorized party intercepts the wireless signals, the actual data payload is unreadable without the associated encryption key, thereby directly addressing the concern of Wi-Fi eavesdropping. For a residential network, configuring robust encryption is a straightforward process typically found in the router's settings.

MAC address filtering controls which devices are allowed to connect to the network but does not encrypt the data being transmitted, leaving communications vulnerable to interception by unauthorized parties within range.

Reducing the signal strength of the wireless router limits the physical range of the network, which might make eavesdropping more difficult from a distance, but it does not encrypt the data itself and can degrade service for legitimate users within the home.
