Organization of corporate networks based on VPN: building, management, security

Abstract

A VPN is a corporate network that is based on a public network and provides similar services for a home network. The
main VPN functions are: a personalized numbering project, providing high-level security and instant access to the abbreviated
number.
A virtual private network (VPN) is a private network, primarily that connects networks, such as the Internet, to public
communication structures. These networks provide security for individual networks through tunneling protocols, such as data
encryption and security measures. For example, VPN can also be used to provide secure access to the network at the head office.
VPN can also connect different, but the same type of network, for example, IPv6 over an IPv4 network.
Typically, there are two types of VPN: remote VPN and VPN for websites. Remote VPN allows individual users to connect
to a remote network, for example, roaming on their company’s internal network. The VPN website takes into account connections of
several users, for example, partner access to the company's network. Virtual networks, of course, reduce costs, because they increase security by reducing the demand for leased lines using existing structures.
