VPNs or Virtual Private Networks are the most recent advancement in the field of networking and since there are so many types of network VPN available, it becomes imminent to become aware of what VPNs are and the different types of network VPN available for us in the market.
Internet is becoming such an integral part of our lives now that it becomes very difficult to envision a life without any internet access whatsoever. VPNs allow users to securely access a particular intranet from outside the premises of a building. They securely and cost effectively connect two organizations by creating one virtual network. VPN technology is also used by day to day internet users to connect to proxy servers and thus, protect their identity on the world wide web. Hence, VPNs are a very important technology and one should know everything there is to know about it. To achieve this goal, ‘TypesOf.com’ is publishing this article.
A Virtual Private Network, or VPN, is a group of computers or networks that are networked together over a public network, that is, the internet. Thus it encompasses a private network over a public network. It becomes possible to share and use resources via a public network as if using a private network. Because the private networks tend to be more secure, functional and are better managed than most public networks, the user of VPNs is benefiting a lot.
A Virtual Private Network is established by a virtual point to point connection using dedicated connections and encryptions. Once someone is connected to a VPN, a VPN client needs to be launched. Then one needs to log in with their credentials and the computers exchange trusted keys with a server. Once both computers have identified each other to be authentic, the internet communication henceforth is encrypted and secured from people not authorized to listen to it. It is vital to use a Virtual Private Network especially when working on an untrusted network.
There are many different types of network VPNs available for use today but which is the right one for us is a major question. The best VPNs offer good features, good server locations, correct and convenient connectivity protocols and all of this comes at a very good price.
There are different types of VPNs. The most commonly used are ‘virtual private dial-up networks (VPDNs)’more commonly known as ‘remote access VPNs’. If the employees of a company who are working from an isolated location require the private network of the company, these User to LAN networks are utilized. The company wishful of remote-access VPN subcontracts to an ESP that is the ‘Enterprise Service Provider’. The ESP puts up a Network Access Server or NAS and provides the company’s employees with a number and sets up software. All the employees then have to do is dial the NAS on a number that is toll free and have admission to the network. VPNs services are used when encrypted and secure connections are required.
The next two VPNs are ‘site to site’, which implies that two or more sites are fixed and connected on a network which is public like the internet. This type of a VPN requires devoted equipment and heavy encryptions. . An intranet is a password-protected site based VPN is used to connect LAN to LAN when a company wishes to network many isolated connections on one private network. Multiple LANs between multiple companies are connected using an extranet VPN which enables efficient work in shared environments.
The benefit of VPNs is that the control is in our hands. They offer security, privacy and anonymity. With the exponential increase in the use and capability of internet, there is an exponential increase in cyber-crimes as well. Knowing the right types of network VPNs thus becomes important in protecting ourselves from such crimes.
