How does a VPN work?
A firewall protects data on your computer, and a VPN protects your data online. Technically, a VPN is a wide Area network that offers the same level of security and functionality as a private network. There are two types of VPN connections: remote access (the computer connects to the network) and network-to-network.
While working on a network without a VPN, you connect to the server of your Internet provider, which, in turn, connects you to the desired site. This means that all your Internet traffic passes through the provider's servers, and the provider can monitor your traffic accordingly.
When you connect via a VPN server, your traffic goes there through an encrypted "tunnel". This means that only you and the VPN server have access to your traffic. However, it is worth noting that there is a certain difference between privacy and anonymity. Using a VPN service does not make you anonymous, since your VPN service knows perfectly well who you are and can view data about your online activity. But the VPN service provides you with privacy when working on the network — in other words, your provider, teachers, Director, or even your government will no longer be able to monitor you. To make sure that a VPN service can really protect you, it is extremely important to choose a service that does not maintain user logs. And this is logical, because if the VPN service logs user actions, the authorities can always demand to transfer this data to them, and in this case your data will no longer be just yours.
Most manufacturers' firewalls support tunneling and data encryption. All such products are based on the fact that traffic passing through the firewall is encrypted. An encryption module is added to the software of the firewall itself. The disadvantage of this method is the dependence of performance on the hardware on which the firewall is running. When using PC-based firewalls, you need to remember that such a solution can only be used for small networks with a small amount of transmitted information. The next approach to building a VPN are purely software solutions. When implementing such a solution, specialized software is used that runs on a dedicated computer and in most cases acts as a proxy server. A computer with such software may be located behind the firewall. Networks vpn推薦 are built using data tunneling protocols through the public Internet communications network, and tunneling protocols provide data encryption and transfer them through users.
VPN allows you to mask your IP address and connect to servers in any other country, which allows access to channels that are allowed only in these countries. You may already have used it, but do you know how it works? Initially, VPN technology was used by employees of enterprises working remotely to ensure the safety of connecting to the local network of their employer, but these days everyone uses VPNs.
