Certified Ethical Hacker (CEH v12) — Question 66

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

Port 48101 is often associated with certain IoT devices and their management interfaces; blocking it can prevent unauthorized access. Ports 22 (SSH), 80 (HTTP), and 443 (HTTPS) are commonly used for secure and standard web traffic, so blocking these may disrupt legitimate use without necessarily addressing the compromise.
