In this video, I have explained introduction of SSH, need of SSH and SSH protocols explain with animation.

SSH stands for “Secure Shell”.

What is SSH?
Secure Shell (SSH) is a protocol for secure network communications designed to be relatively simple and inexpensive to implement.

Purpose of SSH (Need of SSH or Why SSH?)
SSH provides a secure remote logon facility to replace TELNET and other remote logon schemes that provided no security. SSH also provides a client/server capability and can be used for such network functions as file transfer and e-mail.

SSH Protocol Stack:
SSH is organized as three protocols that typically run on top of TCP. There are 3 protocol is SSH protocol stack: SSH User Authentication Protocol, SSH Connection Protocol, SSH Transport Layer Protocol.

SSH Transport Layer Protocol:
It is responsible for server authentication, data confidentiality, data integrity and data compression. SSH transport layer protocol focus on main 3 functions: Host Keys, Packet Exchange, Key Generation.

SSH User Authentication Protocol:
It is responsible for authenticates client (user) to the server. SSH user authentication protocol focus on main 3 functions: Message Types and Formats, Message Exchange and Authentication Methods.

SSH Connection Protocol:
It is responsible for multiplexes the encrypted tunnel into several logical channel. SSH user connection protocol focus on main 3 functions:
Channel Mechanism, Channel Types and Port Forwarding.
