Scanning Networks

🛜 You've gathered intel. Now, it's time to knock on doors. Welcome to Phase 2: Scanning Networks.

In this video, we move from passive intelligence gathering to active discovery. Scanning Networks is where ethical hackers map the target's digital landscape, identifying live hosts, open ports, running services, and potential entry points. This is the critical bridge between reconnaissance and gaining access.

We’ll break down the core concepts of network scanning, from simple ping sweeps to advanced port scanning techniques with Nmap—the hacker's Swiss Army knife. Learn how to see what’s really on a network and how attackers (and defenders) use this information.
💡 Key Skills You'll Learn:
✅ How to use Nmap for fundamental network discovery.
✅ The difference between TCP and UDP scanning.
✅ How to interpret port states: Open, Closed, Filtered.
✅ The concept of "Stealth" vs. "Noisy" scans.
✅ How to identify running services and their versions (critical for finding exploits!).

⚠️ NON-NEGOTIABLE LEGAL WARNING:
ONLY scan networks you own or have EXPLICIT written permission to test. Scanning unauthorized networks (including your workplace, school, or public networks) is:

Likely ILLEGAL (Computer Fraud and Abuse Act, etc.)

Unethical.

Easily detected and will get you blocked or in serious trouble.
Practice on home labs, VulnHub, TryHackMe, or Hack The Box machines ONLY.
