Nmap Scan Types

Nmap offers various scanning techniques to meet different network discovery and security assessment needs.

TCP SYN Scan (-sS)

Fast and stealthy scan that sends SYN packets to determine port status without completing the TCP handshake.

# TCP SYN scan example nmap -sS -p 1-1000 192.168.1.0/24
Open Closed Filtered

TCP Connect Scan (-sT)

Standard TCP connection scan that completes the full three-way handshake to determine port status.

# TCP Connect scan example nmap -sT -p 80,443,22,21 192.168.1.1

UDP Scan (-sU)

UDP port scanning to identify open UDP ports and services running on target systems.

# UDP scan example nmap -sU -p 53,67,123,161 192.168.1.1

Service Version Detection (-sV)

Advanced service and version detection to identify specific software versions running on open ports.

# Service version detection nmap -sV -p 80,443,22 192.168.1.1
