Virtual Network Computing (VNC)

In computing, Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network. VNC is a solution for remote visualisation.

Virtual Private Network (VPN)

Proof that we can adapt flexibly to meet our clients’ security requirements: setting up a VPN is often the basic prerequisite for the existence of a contract. A VPN enables an encrypted connection to be set up in an insecure network, with the aid of VPN gateways. This involves the creation of a site-to-site tunnel, confined by two permanently installed VPN firewalls at two locations. All the data traffic intended for the remote network runs through this “tunnel”.

Another possibility is to install VPN client software on a computer, thereby setting up a tunnel to the VPN gateway of a particular location, through which the encrypted data runs.
