As seen above, after creating the virtual cable, it becomes essentially a virtual tunnel that encrypts data as it passes through it. Now that you know, how it began, let’s try to understand how it works. This is simply how VPNs traditionally came into being to give secure connections to employees of big corporations and business helping them access important files from different locations without posing a risk to security. It is practically impossible to run a cable to connect these two locations instead, the company will create its virtual private network which is like a virtual cable. This is called private network.īut what if the same company has another office say in South Africa employees in SA might want to access the private network in New Delhi. The cables and computers in this office are secure and make it hard for hackers to attack because they are in one physical location and they will have to go there to access them. For instance, you know one company that has an office, say in New Delhi, India. It may not be very easy to understand this, so it’s better if you created a scenario that explains in simplicity.
Many people may not be aware that virtual private networks were created originally for large organizations so that employees could be able to connect to one computer in one office location while they are out in the field maybe working from the field.
Traditionally, VPNs are characterized by point-to-point topology which in most cases does not support to broadcast domains.īefore understanding how they work, it is important to know why they were created in the first place. A VPN can provide many benefits when using extensive area network since the resources in a private network can be accessed remotely. How does VPN work?Ī virtual private network is created through the establishment of a virtual point-to-point connection by employing the uses of dedicated connections, virtual tunneling protocols, and most importantly traffic encryption. This is the same for cooperates and companies that store sensitive information on the internet. VPN servers come in to help users hide their identities and locations so that you are safe as well as anonymous as you enjoy internet use. Unfortunately, it is the same place where most cybercriminals hunt for their victims. Social media, for example, is the biggest platform for internet use where you can find information about any person in the world. It seems as though the modern world is entirely dependent on this technology, whether at home, at school, at the workplace or on the road, you will find a huge number of people using the internet.
