Question

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 wireless communications. What would be the most effective first step to mitigate this risk, considering the simplicity and the residential nature of the network?

Options

  • ADisable the network's SSID broadcast
  • BEnable encryption on the wireless network
  • CEnable MAC address filtering
  • DReduce the signal strength of the wireless router

Why each option

Enabling encryption on the wireless network is the most effective and fundamental first step to mitigate Wi-Fi eavesdropping on a residential network.

ADisable the network's SSID broadcast

Disabling the SSID broadcast makes the network less visible but does not prevent a determined attacker from discovering it through other means and does not encrypt the traffic if they connect.

BEnable encryption on the wireless networkCorrect

Enabling strong encryption (like WPA2 or WPA3) on a wireless network scrambles the data transmitted over the air, making it unreadable to unauthorized individuals attempting Wi-Fi eavesdropping. This is a foundational security measure that directly addresses the concern of intercepting wireless communications and is simple to implement for a home user.

CEnable MAC address filtering

MAC address filtering can be bypassed by spoofing MAC addresses and adds administrative overhead, making it less effective and simple than encryption for a residential network.

DReduce the signal strength of the wireless router

Reducing signal strength might limit the physical range of eavesdropping but can also severely degrade network usability within the home and does not encrypt traffic for those within range.
