Why would you need a VPN?
VPN refers to a discrete network or set of computers that are networked over a public connection. Many organizations and businesses use VPNs in order to remotely connect to datacenters. Individuals also use this to gain access to resources using devices that are not physically connected with the same local area network. However, the most common use of VPN is encrypting online communications that are done over an untrusted network.
The process behind a virtual private network
Whenever a user connects to a virtual private network, it launches a VPN client on the computer. This will prompt that user to log in using the credentials to prove that he or she is indeed authorized to access the network. Once the credentials have been entered, the computer submits a key to the server. The server will check if the key is valid and authentic. The server will also send a key for the other computer to verify. Once the authenticity of the keys has been checked, then the communication can commence. This ensures that the communication via the Internet is secured.
Who will benefit from using a VPN?
The power of VPN may be used in different ways. Its importance will vary depending on who will use it. Below are just a few kinds of users and how they benefit from using a virtual private network.
