Virtual Private Network (VPN)
A virtual private network, also known as a VPN, is a private network that extends across a public network or internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
VPNs can provide functionality, security and/or network management benefits to the user. But they can also lead to new issues, and some VPN services, especially “free” ones, can actually violate their users privacy by logging their usage and making it available without their consent, or make money by selling the user’s bandwidth to other users.
Some VPNs allow employees to securely access a corporate intranet while located outside the office. Some can securely connect geographically separated offices of an organization, creating one cohesive network. Individual Internet users can use some VPNs to secure their wireless transactions.
A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryption. A VPN available from the public Internet can provide some of the benefits of a wide area network (WAN). From a user perspective, the resources available within the private network can be accessed remotely.
