Nmap Command Examples for High School Cybersecurity Projects

📚 Quick Study Guide

• 🎯 Nmap (Network Mapper) is a free and open-source utility for network discovery and security auditing.
• 📡 Basic Scan: `nmap ` scans the most common 1000 ports.
• 🔍 Version Detection: `nmap -sV ` attempts to determine the version of the software running on open ports.
• 🛡️ OS Detection: `nmap -O ` tries to identify the operating system of the target.
• ⏱️ SYN Scan: `nmap -sS ` (default for privileged users) is a fast and stealthy scan.
• 🔥 UDP Scan: `nmap -sU ` scans for open UDP ports.
• 📜 Scripting Engine (NSE): `nmap --script= ` executes Nmap scripts for advanced tasks.
