Certified Ethical Hacker (CEH v13) — Question 129

As a cybersecurity analyst at TechSafe Inc., you are working on a project to improve the security of a smart home system. This IoT-enabled system controls various aspects of the home, from heating and lighting to security cameras and door locks. Your client wants to ensure that even if one device is compromised, the rest of the system remains secure. Which of the following strategies would be most effective for this purpose?

Answer options

• A. Recommend using a strong password for the smart home system's main control panel.
• B. Suggest implementing two-factor authentication for the smart home system's mobile app.
• C. Propose frequent system resets to clear any potential malware.
• D. Advise using a dedicated network for the smart home system, separate from the home's main Wi-Fi network.

Correct answer: D

Explanation

The correct answer is D because using a dedicated network for the smart home system isolates it from the main Wi-Fi network, reducing the risk of lateral movement by attackers. Options A, B, and C enhance security but do not provide the same level of isolation and protection against an overall system compromise.
