A Quick Introduction To The Types Of VPNs

Virtual private networks, or VPNs, have become commonplace for millions of users worldwide both in their personal lives and at work. Basically, they allow computers on separate local area networks (LANs) to connect to each other via a public Internet connection without other people being able to see or intercept the information being sent between them.

Type Of VPN:

There are three types of VPNs that provide users with the several features described above, and they fall into two categories: PC-to-network VPNs and network-to-network VPNs.

A PC-to-network VPN or RAS VPN connects individual device users to a remote network over the Internet as if their devices were actually on an in-situ network. The user simply installs the VPN program via (in the Korean language it is known as을 통해 VPN 프로그램을 설치하기 만하면됩니다.) on his computer that creates a secure connection to a VPN gateway or server on the local network. They are a solution for employees who work from home or on the move and are “moving” and need to have access to work networks, files, and systems.

A network-to-network VPN, or as it is commonly called, a site-to-site VPN briefly connects two separate LANs on the Internet to form a virtual network that uses VPN servers on each network instead of software on separate computers. They can be further divided into Intranet and Extranet VPN.

An intranet allows users/employees in the same organization to join a unified secure network with multiple offices. These intranets are not only password-protected to authenticate each user but they usually only accept connections from the specified network. This makes it ideal for businesses that are spread across multiple locations, so employees can seamlessly work on the same files, folders, and systems.

Extranets work in a similar way but are used to provide shared network space for users not only in different locations but also in different organizations. Therefore, the interconnected networks are under the control of each of these organizations and their respective network administrators. Virtual network coverage becomes more limited so that organizations do not have access to the entire network and internal networks.
