TCP ko samajhna cybersecurity ka foundation hai — aur is
video mein hum sirf theory nahi, balke real packet captures
aur lab demonstrations ke zariye TCP ko andar se dekhenge.
Yeh AppSec aur Purple Teaming series ka doosra episode hai.

In this video, you will learn:
- What TCP is and why it's called a reliable protocol
- How the 3-Way Handshake works — step by step
- Reading real TCP packets in Wireshark
- What a SYN Scan is and how defenders detect it
- How SYN-based denial of service works conceptually
- The difference between offensive and defensive use of
the same protocol knowledge
- Lab environment used: Metasploitable 2 (deliberately
vulnerable VM for safe practice only)

This is Phase 1 — Networking — of the AppSec & Purple
Teaming series. Part 2 will cover UDP, TCP Flags, and
4-Way Termination.
