Securely Accessing the Desktop of a Linux Workstation

A network technician wants to remotely and securely access the desktop of a Linux workstation.

The desktop is running remote control software without encryption.

Which of the following should the technician use to secure the connection?

A.

SSH in tunnel mode

B.

RDP set to console connection

C.

EAP-PEAP

D.

SFTP.

A.

The correct answer is A. SSH in tunnel mode.

SSH (Secure Shell) is a secure network protocol used to establish a secure connection between two computers. SSH provides strong encryption and authentication mechanisms, making it a secure way to access remote computers.

Tunneling is a technique used to encapsulate one protocol within another protocol. SSH tunneling (also called SSH port forwarding) is a way to encrypt traffic between two computers by encapsulating it within an SSH session. With SSH tunneling, a user can access a remote desktop securely by tunneling the desktop traffic through an SSH connection.

In this scenario, the network technician can use SSH in tunnel mode to secure the connection between their computer and the Linux workstation. By using SSH tunneling, the remote control software traffic will be encrypted, preventing anyone from intercepting and viewing the traffic.

Option B, RDP (Remote Desktop Protocol) set to console connection, is not applicable in this scenario since RDP is a Microsoft protocol and cannot be used to remotely access a Linux workstation.

Option C, EAP-PEAP (Extensible Authentication Protocol-Protected Extensible Authentication Protocol) is a security protocol used for wireless networks and is not applicable in this scenario.

Option D, SFTP (Secure File Transfer Protocol) is a secure way to transfer files between two computers, but it does not provide remote desktop access.
