CEH - Certified Ethical Hacker Practice Questions

Master the IoT Hacking Domain

Test your knowledge in the IoT Hacking domain with these 5 practice questions. Each question is designed to help you prepare for the CEH - Certified Ethical Hacker certification exam with detailed explanations to reinforce your learning.

Question 1

You are tasked with assessing the security of an IoT camera. Which tool would you use to intercept and analyze the data packets being sent from the device to identify potential security flaws?

A) Metasploit

B) Wireshark

C) Nmap

D) Aircrack-ng

Show Answer & Explanation

Correct Answer: B

Explanation: Wireshark is a tool designed for network protocol analysis and can be used to intercept and analyze data packets, making it ideal for identifying security flaws in data transmission. Metasploit is used for developing and executing exploit code, Nmap is used for network scanning, and Aircrack-ng is used for wireless network security.

Question 2

In an IoT penetration test, you discover a vulnerability that allows remote code execution on a smart lock. Which action should you take first?

A) Inform the client immediately and provide a patch.

B) Exploit the vulnerability to demonstrate its impact and document it.

C) Attempt to access other devices on the network using the smart lock.

D) Notify the manufacturer and wait for an official response.

Show Answer & Explanation

Correct Answer: B

Explanation: Demonstrating the impact of the vulnerability by exploiting it is crucial for documentation and client awareness. While informing the client (A) and notifying the manufacturer (D) are ethical obligations, showcasing the vulnerability's impact provides evidence of its severity.

Question 3

You are tasked with securing an IoT-connected industrial control system (ICS). Which of the following measures should be prioritized to protect against remote attacks?

A) Segregate the ICS network from the corporate network.

B) Regularly update the operating system.

C) Use default firewall settings.

D) Conduct employee security training.

Show Answer & Explanation

Correct Answer: A

Explanation: Network segregation prevents unauthorized access from less secure networks, thereby protecting the ICS from remote attacks.

Question 4

During an IoT security assessment, you discover a device using outdated firmware. What is the primary risk associated with this finding?

A) Increased power consumption

B) Vulnerability to known exploits

C) Incompatibility with new devices

D) Decreased network bandwidth

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: Outdated firmware often contains known vulnerabilities that can be exploited. OPTION A: Increased power consumption is not a primary risk of outdated firmware. OPTION B: Vulnerability to known exploits is correct as outdated firmware may have unpatched vulnerabilities. OPTION C: Incompatibility with new devices is possible but not the primary security risk. OPTION D: Decreased network bandwidth is unrelated to firmware age.

Question 5

In a network containing IoT devices, you identify several using default factory settings. What is the most effective first step to secure these devices against unauthorized access?

A) Isolate the IoT devices on their own network segment.

B) Change default passwords to strong, unique ones.

C) Disable unnecessary services running on the devices.

D) Install a firewall to filter incoming and outgoing traffic.

Show Answer & Explanation

Correct Answer: B

Explanation: Changing default passwords is a fundamental security measure to prevent unauthorized access. Network isolation (A), disabling services (C), and firewalls (D) are beneficial but do not specifically address the risk of default credentials.
