Secure Shell (SSH)

What Is Secure Shell (SSH)?

Secure Shell (SSH) is a cryptographic network protocol used to secure data communications between two networked computers. It is used to authenticate and encrypt data sent over an unsecured network, such as the internet. SSH is commonly used to access remote servers, transfer files, and manage network services. It is also used to securely tunnel other network protocols, such as FTP, Telnet, and POP3. SSH is a secure alternative to the traditional Telnet protocol, which sends data in plain text and is vulnerable to interception.

Description

Secure Shell (SSH) is a network protocol used to securely transfer data between two computers over an unsecured network.

Usage and Examples

SSH is commonly used to access remote servers, transfer files, and manage network services. For example, a user can use SSH to securely connect to a remote server and execute commands, such as listing the contents of a directory or transferring files. SSH can also be used to securely tunnel other network protocols, such as FTP, Telnet, and POP3. SSH is a secure alternative to the traditional Telnet protocol, which sends data in plain text and is vulnerable to interception.
