A Quick Introduction To The Types Of Vpns.

Whether in personal life or in the workplace, virtual private networks or VPNs (canadian vpn) have become a common phenomenon for millions of users around the world. Essentially, they allow computers on separate local area networks (LANs) to be connected to each other via public Internet connections without anyone having to see or intercept the exchange of information between them.

They are ideal for connecting mobile workers, home or satellite offices, and individuals who need to connect to their home network while on the go. Users can connect to the local network from any device via a virtual private network (VPN), whether it is a desktop, laptop, tablet or even a mobile phone, or from any location anywhere, as long as they have an internet connection. Some people even use a VPN to connect to other places’ networks and then connect to the rest of the world in these physical locations.

VPN technology

In summary, a VPN connects two endpoints (computer, network, etc.) by creating a tunnel, and all information can be transmitted securely. These tunnels are virtual connections that can replace old physical systems, such as dedicated lines that companies should have invested in connecting to their local network.

A virtual tunnel actually involves sending and receiving packets of encrypted information encapsulated in external packets. The outer package is also encrypted and its source and destination are preprogrammed, and only the target points are configured to decrypt them. Packets are used with authentication measures at each end to ensure proper user and device access to the connection. If someone relays a packet that it intercepts on the public network, it can only determine the firewall server/gateway, which is directed, but without the data they contain or their final destination on the local network.

Type of VPN

There are three types of VPNs that provide users with the above functions, divided into two categories: network to network and network to network VPN.

A VPN from a computer to the network or a remote access VPN connects individual device users to a remote network over the Internet, just as their devices are actually on an existing network. Users simply install software on their computers to create a secure connection to a gateway or VPN server on the local network. They are solutions for employees who work at home or on the road and need to “remote access” and access the network, files and work systems.

Virtual private network (VPN) from one network to another or as it is usually understood, virtual private network (VPN) from one site to another, in short, by connecting the Internet to two separate LANs using each network The VPN server, rather than the software in a single machine, constitutes an almost unified network. They can be broken down into VPN Intranets and Extranets.

The intranet allows users/employees from the same organization to connect to multiple secure offices from multiple offices. In addition to being password protected to authenticate each user, these intranets are usually limited to accepting connections from a given network. Therefore, they are ideally distributed in different geographical locations so that employees can work on the same file, folder and system without having to copy each network, or they are on a less secure transmission of traffic on the Internet.

Extranets work in a similar way, but they provide users with a common cyberspace, not only in location but also in the organization. Therefore, networks connected to each other are controlled by these different organizations and their respective network administrators. The current example will be a secure network (canadian vpn) that the provider and its customers can access. The scope of the virtual network will be more limited so that the organization cannot access all of the other networks and intranets.
