Network Security Labs

This repository contains walkthroughs, notes, and exploitation reports from the Network Security learning path.
The focus is on network reconnaissance, Nmap scanning, and protocol analysis, with hands-on examples and screenshots.

Labs Covered

• Passive Reconnaissance
  Using tools like whois, nslookup, dig, and search engines to gather intelligence without touching the target.

• Active Reconnaissance
  Leveraging tools like traceroute, ping, telnet, and web browsers to actively interact with targets.

• Nmap Basic Port Scans
  Performing TCP Connect, SYN, and UDP scans to identify open ports and services.

• Nmap Advanced Port Scans
  Using stealth techniques (FIN, XMAS, NULL, Idle scans) to bypass firewalls and intrusion detection systems.

• Net Sec Challenge
  Applying reconnaissance and scanning techniques in a real-world style lab challenge.
