Virtual Private Network, usually the abbreviation VPN is used. It is a secure connection established between the terminal device (personal computer, smart phone, tablet, etc.) and a server, which is inside the computer network of the organization.
Use of the VPN in practice: Virtual Private Network is used for remote access via the Internet (e.g. from home) into a computer network of the organization - through VPN user has all the options as if he was physically present in the organization. VPN connection is fully secure against disruption or eavesdropping.
