What is a VPN?
A virtual network overlaid on top of the ubiquitous interconnection of the Internet
and a private network for confidential communications and exclusive usage.
VPNs
In a virtual private network (VPN), "virtual" implies that there is no physical network infrastructure dedicated to the private network.
Instead, a single physical network infrastructure is shared among various logical networks
In VPNs, various networking technologies are applied toward the goal of providing private communications within the public Internet infrastructure
Virtual Private Networking: the collection of technologies applied to a public network—the Internet—to provide solutions for private networking needs.
Ubiquitous Coverage - wider coverage compared with the private data network infrastructures offered by telecommunication providers
Cost Reduction - based on the system's economy of scale
Security – using cryptographic technology
E-Commerce - VPNs provide both interconnectivity and security.
