Paper Title
Virtual Private Networks-A Review
Abstract
The tremendous increase in the number of users over the public network (internet) makes it very difficult to transmit the information between two parties in a confidential way. However the demand of getting connected to the internal networks by the employees, organizations, business partners or staff from some external or remote locations so that they can access the internal private network through the public network for transmitting the information in a protected way increases day by day. To achieve the secure transmission of information from source to destination, concept of VPN(virtual private network) was introduced which ensures that the attacker cannot read the data but only the intended recipient can read it.VPN provides a means of transmitting information in a secure way over a publicly accessible network(internet) by creating a temporary virtual tunnel through an insecure public network.VPN serves the functions of a private network with the difference that VPN works over a public network and occupies its own address space. These networks provide all the parameters that are required for security purposes like data confidentiality, data integrity and authenticity. Virtual private networks are used by millions of people everywhere throughout the globe for accessing the websites of their interest that are restricted in their regions, browse the internet namelessly without disclosing their actual identity and true location to sites, offices, government agencies and also from hackers. This paper gives an overview of virtual private networks.
