Understanding Secure Shell (SSH)

A type of cryptographic network protocol for secure data communication

Secure Shell (SSH) is a cryptographic network protocol that enables secure data communication, remote command-line login, and remote command execution between two networked computers.

applies cryptographic methods

SSH applies cryptographic methods to encrypt the data being transmitted between the client and server, ensuring that the information remains confidential and secure.

network services between two networked

SSH provides network services between two networked computers by creating a secure channel over an insecure network, allowing for secure communication and command execution.

sequences of cryptographic primitives

SSH uses sequences of cryptographic primitives to establish a secure connection and encrypt the data exchanged between the client and server, protecting it from unauthorized access.

Question:

What is the type of cryptographic network protocol used for secure data communication, remote command-line login, and remote command execution between two networked computers?

Answer:

The correct answer is Secure Shell (SSH).

Explanation: The protocol being referred to in this question is known as Secure Shell (SSH). SSH is a cryptographic network protocol that ensures secure data communication, remote command-line login, and remote command execution. It works by creating a secure channel over an insecure network to connect an SSH client application with an SSH server. The data sent over this channel is encrypted to maintain privacy and confidentiality.

For example, if a system administrator wants to access a remote server, they would use an SSH client to establish a secure connection to the SSH server running on that remote server. This connection would allow them to send commands and receive responses securely, without fear of the data being intercepted and read by others.
