What Is a VPN, and Why Would I Need One?
Virtual private networks (VPN) help users protect their privacy when browsing and accessing services and web pages when we use unreliable connections such as public Wi-Fi networks since it protects the information we exchange through encryption.
When we surf the Internet, our team connects to another, and information is exchanged between them. For example, if we join an unsecured Wi-Fi network and consult the mail service from the mobile, we connect to a server to which we send the username and password to validate ourselves and it will send the emails to the mobile. Although legally the Internet service provider has to register the connection of our device with the mail server, if someone connected to our wifi spies on us, it could compromise privacy since they would know that we have connected to a specific mail service, or to a server of our company.
That our Internet service provider records all connections, is done due to legal requirements set forth in Law 25/2007, of October 18, on the conservation of data related to electronic communications and public communications networks, there are times when Cybercriminals use it to collect information that they will use to attack us (social engineering).
In addition, in some cases the information we exchange, such as username and passwords, balances, credit card numbers, etc. It is not encrypted, if someone spies on it, it could “read” it without a problem, in case the server to which we connect does not have a digital certificate.
When we send and/or receive encrypted Internet information, the information is not understood, and even if someone spies on it, you will not be able to use it.
Although these issues are not usually of concern in principle, it is necessary to take into account the use of a VPN when we connect to the Internet from “unsecured” networks such as municipal, airport, passwordless, bar, etc. WiFi networks You also have to control others that do not seem as “insecure” as hotel or company networks. In these cases, it would be advisable to try to raise the level of privacy, and especially if we are going to send some important information that we cannot encrypt. One of the areas where it is most about protecting this type of information is in teleworking, where the use of the VPN is already very common.
what is a Virtual Private Network or Virtual Private Network VPN?
A Virtual Private Network is a service through which our team connects to another that acts as an intermediary (the VPN server) between us and the Internet services and web pages that we access (Gmail, Facebook, Dropbox, etc.).
The connection between our equipment and the VPN server is always encrypted so that if someone intercepted our communications, they would be unable to read the information.
Virtual Private Networks divide the connection into two parts or zones, the first goes from our computer to the VPN server and the second from the VPN server to the server or service to which we are going to connect.
Of the two areas, the first is where information could be spied on the easiest, because “sneaking” into our local network is easier because security measures are less because they depend on the user and a very high percentage do not know or they cannot secure it effectively. Many local networks connected to the Internet have a Wifi network, which makes it easy to access the network and spy on it. The routers that are used are of the low range, and cannot provide enough security since the user does not know how to configure them, the manufacturers do not update the firmware of those routers, the default credentials are not modified. So it is easier to spy on us in the first section, exactly from the device to the router
On the other hand, if we intercept communication on our local network, the information they intercept is ours, while the information that comes from the VPN server to the Internet can be from any client that uses that service. So the most important area to protect is the first, and the simplest way is to use a VPN. We always usethe best VPNs like internetetsecurite, diebestenvpn to protect our privacy.
What advantages and disadvantages could VPNs bring us?
What is achieved with a VPN is to create a secure connection, through an unsecured medium such as the Internet? In addition, currently, although there are many users who have access to the Internet through mobile phones (3G / 4G), there are still many users who, mainly to save data, use networks such as municipal Wi-Fi, in airports, bars/restaurants, trains, plane, hotel, etc. of which we do not know the level of security and reliability. VPNs give us advantages in several aspects:
Privacy and confidentiality
There are cases in which knowing where we connect could pose a personal, economic, or business risk. If we connect from an unsecured line to the home computer or to our company, someone could intercept the information and start from it, analyze it and, in the case of credentials, try to access these computers for various purposes, generally not very legitimate… If the connection they can see is with our VPN server, they cannot easily determine the destination of the connection.
On the other hand, if our connection is not encrypted and someone intercepts it, you could use it for various activities such as theft of personal data, theft of credentials, etc. As we explained previously, the VPN always encrypts the data between our device and the VPN server, so if they intercept the information, it will not do them any good.
When information is not encrypted, it could be intercepted and modified to mislead the recipient. If that information is encrypted it could not be modified.
VPNs also have a downside. Among them and the most common, especially on free servers, is that the VPN server provides us with an IP address from another country, so many websites will interpret that we are loading the page from that country and it is possible that the language.
The other major drawback is that communication is usually slower than if it were direct, and in case of free services, in addition to limiting speed, they limit the amount of data we can transfer. In payment services, there are usually no data transfer limitations, although the speed, when using a service that acts as an intermediary, will always decrease compared to a direct connection through fiber optics or ADSL.
Although it may not always be considered a drawback, it may also happen that if we access certain services, for example, our email, we may receive a warning that someone from another country is accessing our credentials from a site that “is unusual”. That someone will be us, but the mail program does not know it, it only warns.
There are many VPN services like privatnostonline & vpnveteran in the market, and some have free usage plans, but limiting the speed and amount of data that we can send and receive. Its operation is based on installing a program, after prior registration, that will connect to the VPN server that we will use. From that moment on, we can consider that our Internet connection from public networks is more secure. Examples of this type of service could be:
