What is a VPN and why is everyone talking about it? Recently, the concept appears in every conversation about the Internet. There is a reason. At one time, the VPN network was just a technical innovation. Currently, it is a tool that everyone needs. The basic task of a VPN is to protect the privacy of the online user so that he does not fall victim to an attack, is not tracked or discriminated by his location.
This guide contains all the necessary information about VPN. When you finish reading it, you'll be an expert in this field.
What is a VPN?
A VPN (Virtual Private Network) is a secure, encrypted connection between two networks or between a user and a network. Thanks to the VPN, you can browse the internet anonymously.
You can depict the VPN network as a digital highway, on which you ride on your stylish "cyber motorbike". You visit your favorite websites, shop in stores, check your data, read news from your favorite sources, play games and do many other things.
If someone cares about it, they can easily follow your footsteps on Internet roads and off-road. To view your online activity, see who you are and where you like to go - all you have to do is look. Even worse, a trail can lead to your home. It's easy to track you down.
VPN works like an invisibility cap - ensures anonymity. It allows you to replace a striking light motorcycle with a rental car with tinted windows. Data encryption and a fake IP address provide you with security and privacy.
A VPN encrypts everything you do online - everything you send and get. If you use the Internet only through a VPN gateway, the connection source shown is one of many VPN routers, not your router.
VPN provides the greatest opportunity for online anonymity without using a TOR network. The TOR network constantly transfers your connection in a widely distributed network of voluntary forwarding addresses. In this way, your online activities are constantly moving and cannot be tracked. VPNs do not use this protocol, but provide sufficient - and necessary - protection when navigating digital highways that are full of hackers and there are no clear regulations.
Why do you need a VPN?
You already know the definition of VPN. Now you will find out why you need it. It is needed more than ever before.
Net neutrality is a requirement for internet service providers to treat all data on the internet equally - without discriminating or favoring. In December 2017, the US Federal Communications Commission lifted net neutrality, which means that your online activities today may be subject to a variety of conditions and prejudices.
The Federal Communications Commission made the first step towards repealing this requirement in April 2017. It abolished the requirement that internet service providers obtain the client's consent to share or sell specific data about him. Currently, Internet Service Providers are free to trade your personal data, geographical location, medical information, browsing history and any other data they collect. The VPN network provides privacy even to your Internet service provider, preventing you from being tracked or having access to your data.
VPNs are currently particularly needed - in every modern cafe the number of laptops matches the number of lattes ordered. Public Wi-Fi hotspot is a real paradise for hackers. If you like to browse the Internet while sipping coffee, use a VPN. It will protect you from tracking attempts by hackers using the same Wi-Fi hotspot.
The recent change in regulations has resulted in an increase in cybercrime, which is why the Internet is starting to resemble the Wild West. A VPN gives you protection in this chaos.
How does VPN work?
Do you want to travel by rented car with tinted windows? If so, always enable VPN before connecting to the Internet. In this way, you will ensure an instant connection to the router of the VPN service provider and you can head to the information highway. No one will see your real IP address because the IP address of the VPN service provider identifies you.
In addition, the connection itself is encrypted, so you can't see what data you transfer, download and send. What is encryption? Encryption is the conversion of readable text into illegible code. There are three main types of encryption: hashing, symmetric cryptography and asymmetric cryptography. Individual types have their strengths and weaknesses, but each type of encryption ensures effective distortion of your data, so that no one can use them.
Most VPNs also offer an additional layer of security in the form of their own name recognition system (DNS). The DNS (Domain Name System) is an online phone book in which text URLs are associated with their respective IP addresses. Thanks to DNS, all you have to do is enter a site name (e.g. "sunless.cloud") instead of a long string of numbers. Cyber criminals can monitor DNS requests to track your online activity. However, the DNS name resolution system within the VPN network blocks these actions by using additional encryption.
