What is VPN and its features
In the global Internet is quite a lotinformation on the VPN connection, but most of the data has a technical tint, which is not easy for a simple user to understand. VPN (Virtual Private Network) is an additional secure network that is located in the World Wide Web. One can imagine that "inside" the Internet there are several third-party protected VPN networks.
To understand what a VPN connection is, you shouldclarify for yourself how it works. There are two points A (virtual private network client) and B (VPN server), between which there is an exchange of encrypted data, thereby providing protection for the tunnel.
Capabilities
The use of such encryptedconnection is very much. Let us dwell on a couple of the most common and understandable to a simple user. The VPN-network hides the real IP-address of the user, which reveals a lot of opportunities. After all, you have access to downloading or viewing video content from a site that is denied access from your country. Well and the main thing - good encryption from the client to the server that provides excellent safety of the transmitted data and packets over the VPN-network.
In practice, one can imagine that access to yourpasswords, credentials, mail and other confidential information can be obtained by using unprotected wireless Wi-Fi data transfer systems, which are almost everywhere (in the metro, cafe or university). In these networks, data transmission is not protected. If you have some data and technical education, dishonest users can do you enough harm.
What is a VPN connection on public networks?
To do this, there is Virtual Private Network to make Internet access secure in public places with Wi-Fi access points. What is VPN, it is easy to disassemble on the following example.
Before you give the password to an attacker or an unscrupulous user of an open public Wi-Fi network, think about it. Protecting your data is easy.
You must create a VPN connection within thisan unprotected network, and immediately after installation, a secure channel will be installed here. Nevertheless, if the data gets into the wrong hands, then the beginning hacker will find it rather difficult to decipher them. After simple manipulation, you can safely go to the post office or to a social network without worrying about data leakage.
The very question of what a VPN is, determine the propertiesnetwork and its advantages: high-quality encryption, user authentication, simple control of network access, low maintenance costs, reliability of communication facilities and large area coverage, ease of connection of new users and networks, simple network settings and control over all activities within it .
The result
We hope that such a VPN is at least a little bitmore clearly. But the main thing is to draw the right conclusion. VPN makes it easy to create a virtual network where computers are not physically connected to each other, but the properties and settings are slightly different from the local one.
Convenience is that you can createanalogue of a local network between computers of users who are in different countries and continents. The only downside is that such a network will not work without an Internet connection. But today most Internet operators offer constant and high-quality access to the world wide web. This is a new round in the development of local networks and the careful organization of corporate networks.
At this stage, this direction is usedand more and more companies are paying attention to their own virtual private network with all the attendant convenience of its use. Of course, a significant portion of the success and quality of this technology will be money investments.
