Certified Ethical Hacker (CEH v12) — Question 167

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?

Answer options

• A. Disable the network's SSID broadcast
• B. Enable encryption on the wireless network
• C. Enable MAC address filtering
• D. Reduce the signal strength of the wireless router

Correct answer: B

Explanation

The correct answer is B, as enabling encryption on the wireless network, such as WPA3 or WPA2, is the most effective way to protect data from being intercepted by unauthorized users. Options A, C, and D offer limited security benefits; disabling SSID broadcast might hide the network's presence, MAC address filtering can be bypassed, and reducing signal strength only limits coverage without securing the data.
