What is VPN? Setting, selection, recommendations
VPN (Virtual Private Network) is a technology that allows you to integrate computer devices into secure networks to provide their users with an encrypted channel and anonymous access to resources on the Internet.
In companies, VPN is mainly used to consolidate several branches located in different cities or even parts of the world into one local network. Employees of such companies using the VPN can use all the resources that are in each branch as their local, located at their side. For example, print a document on a printer that is in another branch in just one click.
Ordinary users of the Internet VPN come in handy when:
- the site is blocked by the provider, and you need to go;
- often have to use online banking and payment systems and want to protect data from possible theft;
- Do not want your sites to track
- there is no router, but it is possible to connect two computers to a local network to provide both access to the Internet.
How VPN works
Virtual private networks work through a tunnel, which they install between your computer and a remote server. All data transmitted through this tunnel is encrypted.
It can be represented in the form of an ordinary tunnel, which occurs on motorways, only paved through the Internet between two points – a computer and a server. Through this tunnel, data like cars sweep between points at the highest possible speed. At the entrance (on the user’s computer), these data are encrypted and go off in such a form to the addressee (on the server), at which point they are decrypted and interpreted: the file is downloaded, the request is sent to the site, etc. Then the data is again encrypted server and the tunnel are sent back to the user’s computer.
For anonymous access to sites and services, a network consisting of a computer (tablet, smartphone) and a server is sufficient.
In general, the data exchange via VPN looks like this:
- A tunnel is created between the user’s computer and the server with the software installed to create the VPN. For example OpenVPN.
- In these programs, a key (password) is generated on the server and computer to encrypt / decrypt data.
- The computer creates a request and is encrypted using the previously created key.
- Encrypted data is transmitted through the tunnel to the server.
- The data coming from the tunnel to the server is decrypted and the request is executed – sending the file, logging on to the site, starting the service.
- The server prepares a response, encrypts it before sending it and sends it back to the user.
- The user’s computer receives the data and decrypts it with the key that was generated earlier.
Devices that are part of a virtual private network are not geographically connected and can be located at any distance from each other.
For an ordinary user of VPN services, it is sufficient to understand that accessing the Internet through a VPN is complete anonymity and unlimited access to any resources, including those that are blocked by the provider or are not available for your country.
Who and why you need a VPN
Specialists recommend using the VPN to transmit any data that should not be in the hands of third parties – logins, passwords, private and working correspondence, work with Internet banking. This is especially true when using open access points – WiFi in airports, cafes, parks, etc.
The technology is also useful for those who want to freely enter any sites and services, including those blocked by the provider or open only to a certain circle of people. For example, Last.fm is free of charge only for residents of the United States, England and a number of other European countries. Using music services from Russia will allow connection via VPN.
The differences between VPNs from TOR, proxy, and anonymizers
The VPN runs on the computer globally and redirects through the tunnel all the software installed on the computer. Any request – via chat, browser, cloud storage client (dropbox), etc. before reaching the destination passes through the tunnel and is encrypted. Intermediate devices “confuse traces” through the encryption of requests and decrypt it only before sending it to the final destination. The final destination of the request, for example, the site, captures not user data – geographic location, etc., but the data of the VPN server. That is, it is theoretically impossible to track which sites the user visited and what sent the requests for a secure connection.
To some extent, VPN analogs can be considered anonymizers, proxy, and TOR, but they all somehow lose to virtual private networks.
The difference between VPN and TOR
Like VPN, TOR technology involves encrypting requests and passing them from the user to the server and vice versa. Only permanent tunnels TOR does not create, the paths of data transmission/reception vary with each access, which reduces the chances of interception of data packets, but not the best way for speed. TOR is free technology and is supported by enthusiasts, so expect stable work is not necessary. Simply put, go to the site blocked by the provider, it will, but the video in HD-quality with it will be loaded for several hours or even days.
The difference between a VPN and a proxy
Proxy, similar to VPN, redirects the request to the site, passing it through the intermediary servers. Only intercepting such requests is easy, because the exchange of information occurs without any encryption.
The difference between a VPN and an anonymizer
Anonymizer – a truncated version of the proxy, capable of working only within the open tab of the browser. Through it, you will be able to go to the page, but you will not be able to use most of the features, and no encryption is provided.
By speed of the indirect communication methods will win proxy, because it does not provide for encryption of the communication channel. In second place VPN, providing not only anonymity but also protection. The third place is for anonymizer, limited to work in an open browser window. TOR is suitable when there is no time or opportunity to connect to the VPN, but it’s not worth it to count on the high-speed processing of bulk requests. This gradation is valid for the case when unused servers located at the same distance from the tested server are used.
How to connect to the Internet via VPN
In the runet, VPN access services offer dozens of services. Well, around the world, probably hundreds. Basically, all services are paid. The cost ranges from several dollars to several tens of dollars a month. Experts who understand well in IT create a VPN server for themselves, using for this purpose servers that provide various hosting providers. The cost of such a server is usually about $ 5 per month.
To prefer a paid or free solution depends on requirements and expectations. Both options will work – hide the location, replace the ip, encrypt the data during the transfer, etc. – but problems with speed and access in paid services happen dramatically less frequently and are resolved much faster.
