The full form of SSH is Secure Shell.
Understanding Secure Shell (SSH)
According to the reference, the Secure Shell (SSH) Protocol is a cryptographic network protocol that enables secure operation of network services over an insecure network. It's commonly used for remote login and command-line execution. In simpler terms, SSH provides a secure tunnel for data transfer between two devices, ensuring confidentiality and integrity.
Key Applications of SSH:
- Remote Login: Allows users to securely access and control remote computer systems.
- Command-Line Execution: Enables the execution of commands on a remote server.
- Secure File Transfer: Facilitates secure transfer of files between systems.
- Port Forwarding: Tunnels other network traffic through the SSH connection.
Security Features
SSH employs several security mechanisms:
- Encryption: All data transmitted via SSH is encrypted, protecting it from eavesdropping.
- Authentication: SSH verifies the identities of both the client and the server, preventing unauthorized access.
- Integrity Checking: SSH ensures that data is not tampered with during transmission.
