What is a VPN
Introduction
In this post ” What is a VPN “, I am going to explain all the information about VPN depending on my expertise in the field of information technology and computer systems.
So, let the story begin. Have you ever connected to the public internet at bus stops, Metro stations, or any other place and wondered that anyone around the world might be able to monitor all your online activities?
This is quite logical, given the good presentation of forces that violate your privacy. In public places, while using open Wi-Fi, you can protect your important data, details, and many other important online activities by simply using the virtual private network.
Mechanism of functioning of virtual networks
When users turn on the VPN, it creates a special tunnel between the user and the remote server that amuses the user with VPN services. Now you will notice in the background that all your internet traffic goes through the private tunnel. So, with this implementation, you are safe over the public internet. Now your location or IP address will be hidden with the IP address and VPN server location. In the end, you are safe and secure.
Understanding the importance of a virtual private network helps to think about some special situations in which a VPN can be used. Consider an open wireless internet connection, perhaps in a cafe or Air Station.
Will you be able to try and make sure to provide Wi-Fi legal, or may be employed by criminals looking to filter out some important information and of your own? Consider the passwords, bank information, MasterCard numbers, and explicit private data you send each time you connect to the internet via this public network.
But if you use a VPN to communicate with a public or open Wi-Fi network, you will be safe from hackers watching all your online traffic and activities even though you are very safe from the administrator as well.
The last point here is really very important and everyone should take into account that it is really difficult to tell the public or open wireless network what it gives an impression.
VPN Applications and their Advantage
With the Virtual Private Network ( VPN) application, you can easily connect to the server located elsewhere in the world and “hide” your identity and location. And if you are outside your region or country, for instance, the United States. You can also access all internet resources in your country or region with the help of a VPN.
In addition, you can do this and vice versa. From the luxurious seats in your home, you can easily go to a remote VPN server, to access entertainment video streaming sites in the United States or elsewhere in the world.
With the help of a VPN, you can also unblock sites that have been blocked by ISP. Some governments have concluded that one of their most important advantages is to restrict access to specific locations for all individuals in their country.
Using VPN, you can bypass these restrictions governmental 100% and enjoy unlimited access to these sites.
Is a VPN required for all internet devices?
In fact, you need to apply a VPN client to all your internet devices. In general, the client application is quite similar for both MACOS and WINDOWS. But in most cases, this is not always theoretically. There is a noticeable difference in the performance of the operating systems.
Concerning mobile phones, the overall situation is slightly different. Many companies offer a client application VPN for iOS and Android. Overall, it’s great because most of the time, we stay connected to the public internet via our smartphones.
On the other hand, the operating system you use does not matter because hackers spy on network traffic. And, for this reason, they do not bother to know which operating system you are using. But there are still specific applications for Windows, Linux, and Android, iOS, and Mac OS you can use to hide your identity online.
Using a Virtual Private Network ( VPN )
Undoubtedly, there are several ways that hackers can track your actions online and can easily follow you. In fact, using a VPN, things like cookies allow organizations to track your web usage even though you don’t use their websites. Fortunately, I have a handy guide suitable for you that you can use to delete site cookies from your web browser.
Only Virtual Private Networks (VPNs) accomplish the anonymity of your actions over the internet. But my friend, if you want to access internet sites in aggregate secretly, and access the dark web for sure, you will need to use Tor.
Tor
Tor is not like a VPN. Total web traffic will bounce back through various server nodes, making it very difficult to track your online footprints. It will be hard to follow you online. The Tor system is developed and managed by an organization and distributed free of charge. Many VPNs have a feature to connect you to a Tor using a VPN to add a layer of security.
Read The Privacy Policy of Any VPN Service
While using any VPN service, you should read the privacy policy of the services because they all work under law enforcement bodies. So, my friend, before choosing any VPN service, you should read the Privacy Policy and Terms of payment to the company.
We have seen that things become very difficult while choosing a VPN. Because companies’ privacy policy consists of specific conditions related to the implementation of the law and the purpose. It is necessary to review the privacy policy of the VPN company before completing any identification.
Can you be safe from Hackers using VPN?
Undoubtedly, it is very easy to wish for a perfect tool that can easily hide your website, IP, protect your online activities, and save you from all possible cyber threats. But to be honest, if someone is chasing you, I must say that he will get what he wants.
Hackers defeat the Virtual Private Network (VPN) with the help of malware or simply analyze the direction of your online activities through Cookies and other resources. But with a VPN, you can also use certain security tools that make you a difficult target.
Complications of Privacy
Virtual private networks practically have many vulnerabilities. You see many website traffic of VPN servers as suspicious and do not allow users to connect to their sites. This is a real problem, especially when the user tries to communicate with his bank while staying outside his native region. Banking websites do not allow traffic from VPN servers.
Chromecast and many other streaming apps and devices can easily send network data locally, but the problem is when the user starts using a VPN server. These devices and application platforms expect web traffic from nearby systems but not from remote servers. Allow several applications to users using the network traffic, but this solution is not possible for cable television and some other devices.
Who doesn’t like Netflix? Netflix vs VPN
If you are a Netflix user, you may be aware of the fact that Netflix does not allow streaming videos when the user uses a VPN. The problem lies in Netflix’s global regional license, which is very strict in its implementation. You can only browse your favorite shows in one country, which doesn’t mean you can browse them in other countries.
On the other hand, VPN companies work day and night to unblock geo-blocking of streaming TV shows and other movies.
Conclusion
At the beginning of the internet era, there were not many things to consider about the privacy and security of the internet. The first days were just a computer network capable of using shared resources and files. There was limited computational power, there was no encryption mechanism, but now everything is running.
Nowadays, many of us have many smart devices that have internet connections that work around the clock 7 days a week. These devices are very powerful and very fast compared to previous ones. Undoubtedly, the internet has made many improvements, but there is still much to consider.
So, my friend, it’s entirely up to you to protect yourself from cyber threats. In this regard, you can use VPNs and many other security programs such as firewalls and antivirus.
