Certified Ethical Hacker (CEH v11) — Question 40

What is the port to block first in case you are suspicious that an IoT device has been compromised?

Answer options

• A. 22
• B. 48101
• C. 80
• D. 443

Correct answer: B

Explanation

The correct answer is B, as port 48101 is often used for IoT communications and could be a target for attackers. Blocking this port first helps prevent potential unauthorized access. The other ports (22, 80, and 443) are more commonly associated with SSH and web traffic, which might not be the immediate concern in this scenario.
