Many things are interested in knowing what is a VPN connection and why it is necessary. Let's deal with this in a simple philistine, we will not pour professional terminology so that everyone can understand what it is. The VPN connection is a secure network (tunnel), created within the Internet, which is not protected. If we consider the easiest view, then this is a tunnel consisting of a VPN client, which is located on the user's PC, and the VPN server. In the tunnel occur:

Encryption;

Changing the information that the user's PC and sites are exchanged on the Internet.

Pluses of this protection

And what is his dignity? Sometimes VPN is required to conceal your IP address to become anonymous user. There are cases when it is necessary to download files from the network prohibiting this from the IP addresses of countries in which customers are located. There is also a need to encrypt traffic transmitting from a user's PC to a destination (destination point). It turns out that there are quite a few situations in which the VPN connection is used.

VPN connection mechanism

Let's consider the example with which you often have to face real life. Nowadays, the popularity of free and often open Wi-Fi networks. They are everywhere:

In restaurants;

In hotels;

In other public places.

The number of devices that can be connected to the Internet is constantly increasing. There are PDAs, mobile phones, netbooks and other devices. This makes me happy modern peopleSince it allows you to connect to your mail in many places, to go to social network, you can now work on vacation that combines pleasant with useful.

But did you think about how safe is it? We are confident that in the open space of unprotected networks, no one steals your credentials and passwords? Not everyone knows, but, analyzing such traffic, not protection, it is easy to access personal InformationBy setting control over your PC. Here it comes to the aid of the VPN connection. You need to install it before connecting through an unprotected network.

How to install VPN.

Windows 7 is not difficult. The principle of almost such as in any you will need a control panel, go to the section called "Network and the Internet", in which click on "Configuring a new connection or network". After that choose the connection option. Speech about the "Connection to Workplace" item, it will allow you to configure VPN. Then you need to specify information on how the VPN connection will be performed. On the existing connection on the Internet or by the dedicated phone number. If you doubt, stop your choice in the first version. At the next stage, enter the IP address (you can name the PC) to which the connection will be with a VPN tunnel. Learn this from then enter the credentials for access. Next Press the "Connect" button.

It is important to create a VPN connection, after installing the protected channel, the interception of data is not afraid. You can safely check your mail, go to the necessary sites under your password.

Imagine the scene from a plenty film in which the villain is surprised from the scene of the crime on the highway on a sports car. He is pursued by a police helicopter. The car enters the tunnel with several outputs. The pilot of the helicopter does not know what the car will appear from, and the villain leaves against the chase.

VPN is a tunnel connecting many roads. Nobody from the outside knows where there will be cars entering it. No one knows what is happening in the tunnel.

You probably have repeatedly heard of VPN. On the lifehaker about this thing too. Most often, VPN is recommended because with the help of the network you can access the content blocked by geographic trait, and in general, improve security when using the Internet. The truth is such that the Internet access via VPN may be no less dangerous than directly.

How does VPN work?

Most likely, you have a Wi-Fi router at home. The devices connected to it can exchange data even without the Internet. It turns out, you have your own private network, but to connect to it, you need to physically be in terms of the router signal.

VPN (Virtual Private Network) is a virtual private network. It works over the Internet, and therefore it can be connected to it from anywhere.

For example, the company in which you work can use a virtual private network for remote employees. With VPN, they are connected to working network. At the same time, their computers, smartphones or tablets are virtually transferred to the office and connect to the network from the inside. To enter the virtual private network you need to know the address of the VPN server, login and password.

Use VPN is quite simple. Usually the company raises the VPN server somewhere on local computer, server or in the data center, and the connection to it occurs with the VPN client on the user device.

Now embedded VPN clients are in all topical operating systems, including Android, iOS, Windows, MacOS and Linux.

The VPN connection between the client and the server is usually encrypted.

So VPN is good?

Yes, if you are the owner of the business and want to protect corporate data and services. Powder employees only via VPN and accountsYou will always know who did what and does.

Moreover, the owner of the VPN can monitor and control the entire traffic that comes between the server and the user.

Employees are sitting in "VKontakte"? You can close access to this service. Gennady Andreevich half of the working day spends on sites with memes? All its activity is automatically recorded in logs and will become an iron argument for dismissal.

Why then VPN?

VPN allows you to bypass geographical and legislative restrictions.

For example, you are in Russia and want. With regret, you will find out that this service is not available from the Russian Federation. You can use it, only leaving the Internet via the VPN server of the country in which Spotify works.

In some countries there is an Internet censor that restricts access to one or another sites. You want to go to some resource, but in Russia it is blocked. You can open the site, only leaving the Internet via the VPN server of the country in which it is not blocked, that is, almost from any other than the Russian Federation.

VPN is a useful and necessary technology that copes well with a certain spectrum of tasks. But the safety of personal data still depends on the blessings of the supplier VPN service, your common sense, attentiveness and Internet literacy.

Today, questions about VPN are popular - what it is what its features and how best to configure VPN. The thing is that not everyone knows the essence of the technology itself when it may be needed.

Even from the side of finance and profit, the configuration of VPN is a profitable case for which you can get easy money.
It would be nice to explain to the user, which represents the VPN, and how best to customize it on Win 7 and 10.

1. Basic

VPN (Virtual Private Network) - This is a private virtual network. Even easier - creating technology local networkBut without physical devices in the form of routers and other things, and with real resources from the Internet. VPN is an additional network created on top of another.

On the Microsoft website, such a cognitive picture was found, which will help to understand that the expression "is additional network created over the other".

On the image shown, the device is displayed as a computer. The cloud is a common or public network, more often - standard Internet. Each of the servers is combined with each other with the help of the VPN itself.

So the devices are connected to each physically. But practice has shown that it is not necessary.

Especially in order not to use wires, cables and other interfering devices, and configures VPN.

Local devices are connected to each other by means of cables, but via Wi-Fi, GPS, Bluetooth and other devices.
Virtual networks, most often - this is a standard Internet connection. Of course, access to devices simply will not work, because everywhere there are levels of identification aimed at avoiding hacking and ill-wishers in the VPN network.

2. A few words about the structure of VPN

The structure of VPN is divided into two parts: external and internal.
Each PC connects to two parts simultaneously. This is done using the server.

The server, in our case, is the so-called guards at the entrance. It will determine and reguse the virtual network.

A computer or device connected to VPN must have all the data for authorization and, so-called authentication, that is, a special, usually one-time, password, or other means, which could help pass the procedure.

This process is not particularly important to us. Professionals are created by increasingly powerful and serious ways of authorization on servers.

To be in such a network, then at the entrance you should know the following:
1. Name, PC name, for example, or other login used to pass on the network;
2. Password, if so installed to complete authorization.
Also, the computer wants to connect to the next VPN network, "carries" all data for authorization. The server will make this data into its database. After registering your PC in the database, you will no longer need to be the aforementioned data.

3. VPN and their classification

The classification of VPN networks is shown below.

Let's try to figure it out more.
- DEGREE OF PROTECTION. Selected on this criteria of the network:
1. Protected fully - these are initially protected networks;
2. Protected "confidentially" - less protected networks are used in cases where the initial or "parent" network is reliable.
- Sales. Methods of implementation. Selected on this criteria of the network:
1. Combined and software methods;
2. Hardware method - Using real devices.
- Purpose. VPN selected on this criterion:
1. Intranet (Intranet) - is used most often in companies where several branches must be combined;
2. Extranet (Extranet) - is used specifically for the organization of networks in which there are various participants, as well as customers of the company;
3. Aksess (Remote Access) is an organization of VPN networks, where there are so-called deleted branches.
- According to the protocol. The implementation of VPN networks is possible using AppleTalk and IPX protocols, but in fact I use most often more often than TCP / IP. The reason is the popularity of this protocol in the main networks.
- Level of work. Here preference gives OSI, but the VPN network can only work on channel, network and transport levels.
Of course, in practice one network, you can include several signs at the same time. Let us turn to direct configuration points. VPN networkWith your PC or laptop.

4. How to configure a VPN network (virtual network)

The first method is designed specifically under Windows 7.
On Windows 7, the setting takes place with sufficiently simple actions and following the following instructions:
1. Go to " Network Management Center and common access " Click on the panel quick access On the connection icon and in the window, choose the item you need.

2. The program does not always have such a species as in the figure above, it may be still like this:

3. In the new window we find the section " Configuring a new connection or network" In the figure, this section is highlighted.

4. In the next point we find " Connect to workplace"And go through" Further».

5. In the event that any VPN connection already exists on the PC, a special window should appear, as in the figure below. Select "No, create a new connection" and again go " Further».

6. In the new window we find " Use my Internet connection (VPN)»

7. Now enter the address, the name of the VPN network. You can find out all the details at the network administrator, which will also tell you the special window.

If the connection happened to the already functioning network, it is best to know the data from the administrator of this network. Usually this procedure does not take much time. Enter data to the intended fields.
8. In the same window, we put a tick to " Do not connect now ...", And after moving" Further».

9. Enter your data (login and password) from the network. In the following figure, these fields are highlighted.

If the connection is the first to with the network, the data will have to create new, after checking with their server you will be passed to the network, and use it.

If the connection is not primary, the server will not check your data and will directly let you in the desired network.

10. After entering the necessary data, click on " To plug».

11. The next window will propose to connect to the network now. It is better to close it.

Setup is safely completed and only to connect to the network remains. To make it need to go back to the first item " Center Network Management and Shared Access».
12. In a new window, choose " Connect to the network».

13. Here you choose our connection and connect it.

Configure VPN on Windows 7 Completed.

Let us turn to the VPN configuration on Windows 10, the algorithm and the action there are almost the same. Difference only in some interface elements and access to them.

So, for example, to get to the "Network and Common Access Center" need to do everything that both on Windows 7, besides there is a special item " Creating and configuring a new connection or ...».
Further, the setting is done in the same way as on Windows 7, only the interface will be a little different.

Some inconvenience of Windows 10 users may be related to the fact that they will look for a classic network type. Should go to " Network and Internet", And after selecting" Viewing the Status of Tasks and Networks "for further work with setting up NPN networks.

In essence, there is nothing difficult in the setup. By the way, such a VPN connection can be configured even on Android devices, it will be devoted to this section below.

5. Setting up VPN on Android

To perform such an operation, you will need to install and download the tool called SupervPN Free VPM Client from Android official stores.

The window of the program that will offer creating a VPN. Networks on android.

In general, everything is clear here, click on " Connect.", After which the search for available networks will begin and further connection with them. Configuring VPN on Android is made without additional programs.

VPN and proxy servers have one similarity: they are designed to protect confidential information And hide your IP address. On this similarity ends.

Proxy or VPN.	Proxy	VPN.
Access to any content

Protects you OT. malicious programs and phishing tactic
Constantly changes the virtual location (IP address)
High Speed \u200b\u200bSurfing and Streaming Content
Output As you can see, VPN is superior to a proxy server. Both services allow you to hide IP ADERS, but additional functions VPN - reliable encryption, comprehensive system protection, etc. - Make tax technology more secure and confidential than proxy server.

Hi friends! Many people use the Internet on the principle of "I have nothing to hide", but it's like saying "I don't care about my rights." This article is for those who do not care about their rights, as well as for those who think about security on the Internet. I'll tell you simple words About what VPN is, why it is needed, as well as how to use it.

What is VPN.

VPN is decrypted as Virtual Private Network. Translated into Russian - a virtual private network. VPN is a technology that provides an encrypted connection over your Internet connection.

Thanks to the VPN, you will be protected from interception of logins / passwords in unprotected or public Wi-Fi points, the history of your sites will not be available to anyone, but you will forget sites like a terrible sleep. This also applies to torrents, and to any other allegedly prohibited sites.

The project of the projects of the "blockers" also reached. Recently, the popular Bitcoins Exchange, a major investment forum and still unknown how many sites was blocked. Block can and access to the site any payment system, for example, to. The benefit that the ridiculous blocking of VPN users do not touch :)

What makes VPN

1. VPN replaces your real IP on a duct, for example, to Italian or Dutch, if you use VPN, then you are practically invisible in the network. You go to the site, but see that you, for example, not from Russia, but from Germany. Due to this, no blocking sites are not terrible.

2. Environment is encrypted - neither your provider nor a sysadmin knows where you came out.
- What does the sysadmin / provider sees at all when you do without VPN? The whole story of your surfing, all the sites, which you come to.
- What does he see when you work via VPN? What you connected via VPN and ... everything, nothing more is not known :)
As well as attackers when intercepting data, they will not be able to recognize them due to encryption.

3. In the amount of IP substitution and traffic encryption, you become completely anonymous.

Why do you need VPN.

• If you like to visit the cafe and sit there online via Wi-Fi or travel and connect and connect to open Wi-Fi Points - No arrogant hacker sitting at the next table, will not capture your plastic card data with CVV code or not password steals From the payment system along with your money. Moreover, it does not matter whether you work from a laptop or from a mobile device - without VNN, they are equally not protected.
• You value anonymity and you have a unpleasant fact that any sysadmin provider has access to visiting sites you visited or from which EPS you replenish / remove large sums. The provider will no longer know which sites you visit, and sites will not know who visited them.
• At work, love to sit on YouTube / Vkontakte / Skype, but do not want this to spoil the boss or sysadmin. I know that you are a successful investor and do not go to work for a long time, this is me, just in case :)
• Want to see the Internet as it should be - to visit sites without restrictions service, which just blocks sites. At the time of writing, more than 2 million sites are blocked (statistics are conducted). It is also not uncommon when you require blocking a specific page or partition, and the provider does not understand the entire site.
• Favorite service restricts access from your country or provides privileges / bonuses / discounts to specific countries? With the help of VPN, become a resident of any country and get all the advantages of the services.

How to use VPN (on the example of NORDVPN)

I myself sit on the Internet only through the VPN and I can recommend an excellent service called NordVPN. I will say right away, the service is paid, the cost of $ 12 per month, when paying for half a year, the cost per month is $ 9, when paying for a year - $ 7.

Yes, on the Internet is full of free VPN ServicesBut the content of the servers costs money, so if the service does not take payment from you, it earns on you somehow differently and this "otherwise" can do it much more expensive than paying a reliable VPN.
