Day 7: Network Scanning with Nmap | Host Discovery, Port Scanning & Vulnerability Detection 🔍🌐

Welcome to Day 7 of the 15-Day Cybersecurity Workshop 2025 by Code for Change – Chitwan! 🧑‍💻🔎
Today, we unlock the power of Nmap, the must-have tool for network reconnaissance and vulnerability scanning. Learn how to discover hosts, scan ports, detect services, and identify security weaknesses in your target environment.

🔥 What You'll Learn in This Session:

⚡ 1. Nmap Basics
• Host discovery with nmap -sn to find live machines
• Different port scanning techniques:

TCP Connect Scan: nmap -sT

SYN Scan (stealth scan): nmap -sS

UDP Scan: nmap -sU
• OS detection and service version scanning: nmap -O -sV

🛠️ 2. Advanced Nmap Features
• Using NSE (Nmap Scripting Engine) scripts for vulnerability detection: nmap --script=vuln
• Scanning multiple targets or entire subnets
• Techniques to detect firewalls and bypass filters: nmap -PN, --badsum
• Exporting scan results in different formats:

Normal output: -oN

XML output: -oX

Grepable output: -oG
