A VPN is short for a Virtual Private Network. This would be an infrastructure that moves a private network across a public space, such as the space of the Internet, without allowing the public to access the contents of the private network.
How Can a VPN increase Security?
One of the key points that readers need to understand about a VPN goes back to part of the VPNs definition, moves a private network across a public space, this can also be translated as securely moving data outside of your network. That; however, is not all that a VPN does. It literally extends your network. When you use a VPN, your data does not end up on the Internet because it goes through the Internet. The security part is that using a VPN moves your data without the public having access to it.
So each time you visit the Internet your computer shares information with each website that you visit. If you are trying to upload data or download data, the Internet keeps a record of that. Nothing that you do on the Internet is private, except when you utilize a VPN. So whatever information that you send along the VPN is kept private. This is because the VPN interacts with websites for you without sharing your IP Address, or personal data.
A Trojan Horse, which is malware that can damage your computer or steal your data, needs only 20 minutes to find a host once it is unleashed. This is primarily because it can follow IP Address back to the computer. If your computer’s IP Address is known, then your computer is at risk. So another way that a VPN helps to protect you is by keeping your IP Address unknown.
How Does A VPN Work?
A VPN works in several ways. Below we will explore some of the ways that a VPN works.
Another way to describe what a VPN is, is to say that it is a connection to a connection. What this means is that the VPN acts as your connection to the Internet. So your Internet connection connects to the VPN which then connects you to the Internet. In doing so, the VPN accepts all of the necessary data that your computer’s IP Address contains and then issues you a false IP Address that your computer then uses at it travels about the Internet.
Another way that a VPN works is by created tunnels that allows your computer to connect securely to a specific location on the Internet. The only thing inside the tunnel is the data that you download or upload. There are no prying eyes, hackers, no virus or malware.
Some countries block access to websites that originate in that country. A VNP can circumnavigate those security measures by allowing your computer to log onto a VPN server within that country. Once you log onto the server that is in that country, the Internet thinks you are from that country, and you are no longer denied access to public websites within that country. A quality VPN has many servers in many countries. The more servers a VPN has the better the network works.
