Certified Ethical Hacker (CEH v11) — Question 249

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

Answer options

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

Correct answer: C

Explanation

The correct answer is C, as the '-sS' option in Nmap initiates a SYN scan, which is a type of stealth scan that does not complete the TCP handshake. Option A, '-sM', represents a Maimon scan, which is not a stealth method, and Option B, '-sU', is for UDP scans, while Option D, '-sT', is a TCP connect scan that is not stealthy.
