SSH, or RDP and VNC? — TechKnowSurge

About this interactive

A jump server, also called a jump box or jump host, is a machine inside the network that is the one thing outside users can reach through the firewall. They remote into it, and from it they reach other resources. That is good for security: the rest of the network is not opened to the outside, and anything downloaded from a server lands on the jump server, not on the user's laptop. All the laptop receives is data describing the desktop. There are several ways to connect to it. SSH, secure shell, gives a command line. It suits Linux and other machines that have no front end, where the work is done by typing commands. For a full desktop experience, use RDP, remote desktop protocol, or VNC, virtual network computing. Each has software that sets up the connection. To sort a card, ask whether the work needs a command line or a full desktop.

What you'll learn

Choose SSH for a command-line session to a jump server, and RDP or VNC for a full desktop session
Explain why a jump server protects a network: outside access reaches one machine inside, and the data stays on the network

Key terms

Jump Server: A hardened intermediary host used to provide controlled access to devices within a separate network segment, also known as a jump box or jump host.
Secure Shell: A cryptographic network protocol that provides secure remote login and command execution over an unsecured network.
Remote Desktop Protocol: Remote Desktop Protocol is a Microsoft protocol that enables remote graphical access to Windows systems; it is a frequent attack target commonly exploited via credential brute-forcing, session hijacking, and unpatched vulnerabilities such as BlueKeep.
Virtual Network Computing: Virtual Network Computing is a graphical remote desktop sharing system; in security contexts, unsecured VNC instances with weak or absent authentication are a common target for unauthorized remote access and lateral movement.
