Episode 22 — Tell the Story of TCP, UDP, and Web Communication Handshakes
Reliable data transport is the backbone of digital communication, and this episode tells the story of the Transmission Control Protocol (T C P) and the User Datagram Protocol (U D P) through the lens of their unique handshake mechanics. We deconstruct the T C P three-way handshake—S Y N, S Y N-A C K, and A C K—which establishes a formal, connection-oriented session to ensure every packet arrives in the correct order and without errors. In contrast, U D P is described as a connectionless protocol that prioritizes speed and low overhead for real-time traffic like streaming or gaming, though it lacks the delivery guarantees and error-checking of its counterpart. The discussion extends to web communication, explaining how these transport protocols support the subsequent Secure Sockets Layer (S S L) or Transport Layer Security (T L S) handshakes used to encrypt H T T P traffic. For a security professional, understanding these handshakes is critical for detecting anomalies like S Y N floods or identifying which protocol is appropriate for a specific business application. This technical clarity ensures you can analyze network traffic and firewall logs with seasoned expertise.
