Certified Ethical Hacker (CEH v10) — Question 34

What would you enter, if you wanted to perform a stealth scan using Nmap?

Answer options

• A. nmap -sU
• B. nmap -sS
• C. nmap -sM
• D. nmap -sT

Correct answer: B

Explanation

The correct answer is B, as 'nmap -sS' initiates a SYN scan, which is known as a stealth scan because it does not complete the TCP handshake. The other options represent different types of scans: A is a UDP scan, C is an M scan (not a standard option), and D is a TCP connect scan, which is not stealthy.
