Secure Shell (SSH)

February 17, 2023

Secure Shell (SSH) is a cryptographic network protocol to secure network connections between computers. It is commonly used to remotely access, manage, and configure servers, routers, and other network devices and to transfer files securely over an insecure network.

Secure Shell (SSH) uses a combination of public key and symmetric key encryption to secure the client and server connection. The client and server exchange keys during the initial connection, and all subsequent communication is encrypted using these keys. This ensures that the data being transmitted is protected from eavesdropping and tampering.

SSH includes many features that provide a secure and flexible way to access and manage network devices remotely.

Features Of Secure Shell (SSH):

Authentication: SSH supports several authentication methods, including password-based and key-based methods, which provide a secure way to verify the user’s identity.

Encryption: SSH encrypts all data transmitted between the client and server, protecting from eavesdropping and tampering.

Tunneling: SSH can create secure tunnels between two networks, allowing secure communication.

SCP: Secure Copy Protocol (SCP) is a protocol that allows secure file transfer between computers using SSH.

SFTP: SSH File Transfer Protocol (SFTP) is a secure file transfer protocol that runs over SSH.
