Certified Ethical Hacker (CEH v13) — Question 137

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 is the most effective way to protect data from being intercepted during transmission. While disabling SSID broadcast (A) and reducing signal strength (D) can offer some security benefits, they do not encrypt the data. MAC address filtering (C) can be easily bypassed by knowledgeable attackers, making it less effective than encryption.
