Using a VPN
Today, we need to access resources in many ways—from homes, businesses, in airports, or while on vacation. Because of the many threats to our data in a complex world, many businesses and individuals use a VPN to securely transmit data.
Important note
The term VPN stems from the idea that the technology secures data that originates in a private protected network that must travel across an insecure public network.
The concept of a VPN started over three decades ago in the 1990s, when a Microsoft engineer developed the Point-to-Point Tunneling Protocol (PPTP), which was a precursor to today's VPNs. This functionality was included in Windows operating systems, and businesses soon began using the technology. After setting up a secure tunnel, clients were able to access network resources in the same way they would if they were sitting in the private network, but remotely using cryptographic tunneling protocols.
Time has passed, and today's VPN technology...
