SSH | What is SSH? | SSH Protocol Stack | SSH Protocols explain with animation | Why SSH? | Secure Shell (SSH) Follow my blog: 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. 0:00 Introduction 0:15 Outline 0:39 Introduction of SSH 1:15 Introduction of SSH Protocol Stack 1:54 SSH Transport Layer Protocol 10:17 SSH User Authentication Protocol 14:53 SSH Connection Protocol 24:26 SSH Protocol Summary If you like my video contents, please LIKE, COMMENT, SUBSCRIBE & SHARE with your friends. -------------------------------------------------------------------------------------------------------------- Check out other videos on my channel: Web Security Threats and Approaches: SSL Architecture & Protocols: HTTPS: SSH: -------------------------------------------------------------------------------------------------------------- You can always connect with me at: Follow my blog: Like my Facebook page: Follow me on Instagram: Follow me on twitter: Join telegram group: Subscribe me on youtube: Follow me on Quora: -------------------------------------------------------------------------------------------------------------- Playlist available on my channel: Network Security (CNS, INS, IS): Computer Network (CN) with animation: VFX Animation & Fun Videos: Comupter Organization & Architecture (COA, CA,CO): Assembly Language Programming: Computer Graphics: #chiragbhalodia #chirag_bhalodia #networksecurity #cryptography #ssh #ssh_protocol_stack #ssh_protocols #SSH_connection_protocol #SSS_authentication_protocol #SSH_transport_layer_protocol #need_of_ssh #purpose_of_ssh Keep learning, keep supporting 🤝✨💯
