VPN Technology: A Guide

July 5, 20198min

Work on the internet requires a high level of data security, and setting up a VPN connection to the server will effectively solve this problem and ensure absolute confidentiality on any network.

Nowadays, this technology is actively used by both large companies and individual users, since it fulfils its task one hundred percent.

Key features of VPN technology

A virtual private network is technology that provides the creation of one or more tunnels, located on any other system when connected to the internet. The tunnel  is secured using robust cryptography algorithms, and according to VPN-review.com, such means as authentication, protection against a repetition of data, encryption, and critical public infrastructure are used.

Depending on the settings, a VPN provides a connection of three different types:

  • network-to-network
  • network-to-device
  • device-to-device

The network-to-network VPN connection is straightforward for clients and controlled by the framework manager on the server.  However, its fundamental disadvantage is the absence of encryption inside the system.

VPN compatibility with various operating systems

Creating and configuring a VPN connection is possible based on the most common frameworks. At times, you simply need to download and run a special program. For this situation, the VPN connection will be made with the servers for which the utility was made.

Protocols bolstered by working frameworks are involved in VPN connections with corporate systems. PPTP is utilised in Microsoft Windows customer and server versions. When using Linux, PPTP-Linux customer and PPTP server are required. Independently, an MPD server with PPTP and L2TP backing is executed.

For gadgets running Mac OS or Android, no outsider applications are required because the capacity to use VPN is incorporated into them. Installation and setup of VPNs should be possible not just on PCs or smartphones. As of late, L2TP and IPSec conventions are made by Cisco routers (from OS form 11.3T). Likewise, the capacity to utilise a VPN is available in individual firewalls.

Benefits of using a VPN connection

Connecting to a server through a VPN has several economic advantages. Since the work does not need a dial-up connection, there is no need for modems or a dedicated line. It’s enough for a user to have a device with Internet access to easily connect to his corporate network. The general availability of data does not mean that they are not protected. A VPN connection is a secure shield that protects all information from unauthorised access or interception.

The global development of the internet makes it possible to use limitless amounts of information present on various resources. The Virtual Private Network makes it possible to reduce the costs of internal corporate communications and make the transmitted and received information more secure and confidential.

Among the options for implementing a VPN are software and hardware products. A ready application installed on a computer refers to a software solution for VPN. Many companies offer to use this service by connecting to servers that belong to them. Some developers supply VPN packages that interact with software firewalls and operate on different operating systems.

Software products are relatively inexpensive. The hardware method of using VPN implies the presence of a computer, a private operating system, and specialised software. It has high performance, but its cost is also high.

The VPN device is located between the internal network and the web at the end of the connection. During transmission, data disappears at the point of origin. It is then encrypted and appears only at the destination. For guaranteed access to the data of individual users only, the private network can be amplified by an appropriate authentication protocol.

Moreover, VPN is often used by providers to control network access. Simply put, the user connects in the usual way, and then starts the VPN client for further work online. It helps to protect the connection from hackers and organise personal access.

Not all VPN services are equally useful

With free VPN services, you can save a lot of money, but only at the expense of your security. Other VPN services may have the most advanced security system and low connection speed (the more complicated the encryption, the lower the speed). Of course, this service is not well suited for those who want to work online and want to finish a job fast.

Therefore, be careful when choosing a VPN provider.
