As more and more of us work on the go, from home or from the personal devices we carry to work, it is becoming increasingly important to adopt the technology behind a VPN that allows us to access office networks “remotely” from our freedom to use work practices flexibly. The following article provides a brief guide on how this works.

Quick Definition:

However, before doing that, it’s worth taking some time to look at what a VPN is and what it does. VPN stands for Virtual Private Network and is a term that includes a set of technologies that allow users to remotely connect to a network securely over a public network, which in practice usually means the Internet.

There are two types of VPNs in total. The former can be called remote access and allows one user or device to access a network elsewhere on the Internet. The second can be referred to as site to site and involves linking a network in one place to a network at another.

The main characteristic of a VPN is that it enables secure communication between individual networks. That is, they allow data to move between networks without being seen or accessed by those who shouldn’t be able to with the proper connection stability (written as 연결 안정성 in the Korean language). To do this, a VPN must ensure that the right people have access to the virtual network at all and not allow people to intercept data while traveling over the Internet.

How Does It Work:

To achieve the former, devices must be authenticated at each end, mostly by the use of secure passwords, but also mechanisms such as digital and certificates biometric scanners for the devices themselves. This ensures that counterfeit devices cannot be set up at both ends to intercept data or break into the network, or to prevent fraudsters from accessing the device and network.

To achieve the second goal, VPNs create what are known as “tunnels” on the Internet, through which information can be removed from sniffing or sniffing ranges as they are called. In its simplest sense, a tunnel involves encrypting information at one end of the data transmission and then decoding the information at the other.
