services can crash a PLC, and the safety rules differNmap Scanning Strategies:
# Quick TCP scan
nmap -sC -sV -oA scan 10.10.10.10
# Full TCP port scan
nmap -p- -T4 10.10.10.10
nmap -p- -sV -sC -A 10.10.10.10 -oA full-scan
# UDP scan (top 1000)
sudo nmap -sU --top-ports 1000 10.10.10.10
# Aggressive scan
nmap -A -T4 10.10.10.10
# Specific port scan with scripts
nmap -p 445 --script smb-* 10.10.10.10
nmap -p 21 --script ftp-* 10.10.10.10
# Service version detection
nmap -sV --version-intensity 9 10.10.10.10
# OS detection
sudo nmap -O 10.10.10.10
Fast Port Scanning:
# masscan - very fast
masscan -p1-65535 10.10.10.10 --rate=1000
# rustscan - fast with nmap integration
rustscan -a 10.10.10.10 -- -sC -sV
