What is SSH? Secure Shell Explained for Beginners | Remote Server Access in Linux
Secure Shell (SSH) is one of the most important tools used by Linux administrators, DevOps engineers, and cloud professionals to securely manage remote servers.
In this video, we explain what SSH is, how it works, and why it replaced older protocols like Telnet for remote server access.
SSH uses strong encryption to protect sensitive information such as usernames, passwords, and commands while communicating over a network. This makes it a secure and reliable way to manage servers from anywhere in the world.
You will also learn about the SSH client-server model, authentication methods, and how administrators use cryptographic key-based authentication to improve security.
Topics covered in this video:
• What is SSH (Secure Shell)
• Why SSH replaced Telnet
• SSH client and SSH server architecture
• Password vs SSH key authentication
• Default SSH port and configuration basics
• Real-world usage of SSH in Linux administration and cloud environments
Whether you are learning Linux administration, cloud computing, DevOps, or cybersecurity, understanding SSH is a fundamental skill for managing modern IT infrastructure.
