Remote-Protokolle

Remote protocols

Remote protocols are communication protocols that allow computers, servers or other IT systems to be controlled or managed remotely via a network. They enable access to devices as if you were sitting directly in front of them – even though they are physically located elsewhere.

 

What exactly are remote protocols?

Remote protocols regulate the way data is exchanged between a client (the device requesting access) and a server (the remote target device). Well-known examples of remote protocols are:

 

  • RDP (Remote Desktop Protocol) – commonly used in Windows to access remote desktops.
  • SSH (Secure Shell) – mainly used in Linux environments for secure control of servers via the command line.
  • VNC (Virtual Network Computing) – allows remote control of computers via graphical interfaces.
  • Telnet – an older protocol that is hardly used today because it does not offer encryption.

 

Why do you need remote protocols?

Remote protocols enable IT administrators to configure servers, troubleshoot problems or install software without having to be on site. Employees working from home or on business trips can also access their office computers via remote protocols.

 

Where do you encounter them in everyday life?

  • In IT support, when technicians remotely solve a problem on your computer.
  • In server administration, e.g. when installing updates on a web server.
  • In the home office, when you access your workplace in the office via Remote Desktop.
  • In the remote maintenance of machines, for example in industry or in cash register systems.

 

Security note:

Since remote protocols enable direct access, they are popular with cybercriminals. They should therefore always be secured with strong passwords, two-factor authentication and, where possible, encrypted protocols such as SSH or RDP via VPN.
