An approach to Virtual Private Networks and security
Himanshu Monga · International Journal of Advanced Research in Computer Science · 2017
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 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.
