Question 83

A pentester is trying to map the organization's internal network. The analyst enters the following command (nmap -n -sS -T4 -p 80 10.0.3.0/24). What type of scan is this?
  • A Quick Scan
  • B Intense Scan
  • C Stealth Scan
  • D Comprehensive Scan
Reveal correct answer

Correct answer: C

Explanation

OBJ-2.2: In nmap, the -sS flag signifies a stealth scan. This is also known as an SYN scan and is the most popular scan option for good reasons. It can be performed quickly, scanning thousands of ports per second on a fast network, and is not hampered by restrictive firewalls. It is also relatively unobtrusive and stealthy since it never completes TCP connections.
