Networking Fundamentals Every Pentester Must Know (N-01 → N-10) | T4Threats

If you’re learning web application pentesting but your networking fundamentals aren’t solid, every vulnerability will feel like trial and error — you’ll be reproducing steps without actually understanding how the attack works.

In this video, we cover the full Networking Fundamentals foundation — from the Client-Server Model to Network Hardware, across 10 modules (N-01 → N-10):

• N-01: Client-Server Model — the request/response chain every attack sits on top of
• N-02: OSI & TCP/IP Model — every layer mapped to its attack surface
• N-03: IP Addressing — public/private ranges and NAT
• N-04: MAC Addressing & ARP Spoofing — the mechanics of the classic MITM attack
• N-05: TCP vs UDP — the 3-Way Handshake explained
• N-06: Ports & Protocols — the pentester’s cheatsheet
• N-07: DNS — a recon goldmine (zone transfers, dangling CNAMEs, crt.sh)
• N-08: DHCP DORA Process — rogue DHCP attacks
• N-09: Routing & Default Gateway — common lateral movement paths
• N-10: Network Hardware — comparing Hub, Switch, Router, and Modem sniffability

This series is built specifically for Red Team and Web/App Pentesting — theory paired with practical attack context at every step.
