In USA, the increase in the use of VPN is inevitably observed along with access barriers. This situation, which is not overlooked by international companies, results in some VPN service providers conducting special campaigns for our country.
VPN means virtual private network in English and connects you remotely to a physical network where you are not. Some people use this technology to connect to their company’s local network as if they were there, but because of some necessity, it is a miraculous solution that allows access to sites where VPN cannot be accessed for the citizen who has to learn the concept just like DNS.
1 – How does VPN work?
Although VPN uses many different protocols and technologies, it basically provides an encrypted (crypto) tunnel from where your computer is physically located to the opposite network. Information transmitted through this tunnel cannot be viewed externally because it is encrypted from the outside. Security experts who see the issue see encrypted data flowing, but cannot understand what the content is (unless it uses very weak security). VPN solutions install a customized network driver (or embedded on mobile devices) on your computer or mobile device, where it acts as a virtual network adapter, giving you an IP number from the opposite network. This allows you to access permitted applications or local addresses.
2 – What types of VPN systems and uses are there?
Nowadays, there are three different popular VPN usage. One of these is the basic mechanism in how it works, for example VPN systems that allow you to connect to your office computer, office systems, services or your computer from your home computer. With these systems, you can enter and operate a remote network as if you were there. You can do this very safely.
Cloud SolutionsThe second usage area is the systems which are very common in our country except for business use, collecting all traffic collectively and delivering to the internet environment from a different location (usually from another country). An advantage of this VPN technology is that it works especially in public networks. For example, you have a wireless network that you connect to, whether encrypted or unencrypted. If there is a password, other computers connected to the network, if there is no password, everyone in the area can see the data flowing here and use the social engineering techniques to create attack vectors related to you or your company. At this point, the VPN system provides almost complete security as it removes “sniffing” (sniffing, collecting and analyzing data packets) data from your computer or mobile device from the network to the internet. From this point on, you can browse the interent, synchronize your files in cloud services without showing which service you are using, and send files more securely over unsecured FTP services.
The last type of VPN is specialized systems that save players’ lives and reduce server response times due to routing problems. These systems solve the problem of your internet service provider from point to point without distinguishing the game data and draw you a shorter route and affect visibly and reduce nerve coefficients especially in multiplayer online games which we call MMO. They may be cheaper or more expensive than previous VPN solutions, but they are often life-saving because they have constantly updated settings from game to game.
