Use of a VPN for telework

As its name suggests, a private network is extended across a public network with an encrypted connection of a device to a network. It enables users of a network to utilize management facilities of vast networks and exploit economies of scale. Users are able to securely transmit and receive information across shared networks in a way that is similar to devices directly connected to a private network. Usually, applications from a client's device are loaded to a physical channel of the local network transmitted to a public network, in this case, the internet, and decoded to the server's system by yet another physical local network.

With a VPN, the process is shortened and made even more secure by the connection of a client’s device directly to the server by use of a private, virtual, and secure channel. Its primary purpose is to create remote access to corporate resources and applications. VPNs are primarily used to create a vast area network that covers broad geographic zones providing an end-to-end connection to the network offices and allows users to contact their Local Area Network companies. A VPN enables the segregation of different customers’ traffics on a network, and each is transmitted on its own. It also interconnects multiple analogous networks over a distinct network. Virtual private network systems can be classified by the protocol used in channeling traffic, connection's topology, security levels provided, number of concurrent connections, the location point of a tunnel's termination, and OSI layer presented to a connecting network. (Stallings, 2011).

VPN facilitation of data safety

A VPN is an assurance of the safety of data since its technology is ideal and bulletproof. A tunnel is created to transmit encrypted data between a source and the destination, and hackers cannot inflict damage on the data since the location and data are invisible and inaccessible. Change of an IP address in collaboration with a Virtual Private Network hides identity from any third party that is after your identity and conceals your data from mobile carriers and any snoops making the data safe. Authentication by the use of passwords and other security keys is also useful in the privacy and security of data in a VPN (Wright, 2000).
