Information Security Concepts

VPN technology is based on tunneling. It requires establishing and maintaining a logical network connection. Packets created in a particular VPN protocol format are encapsulated inside another base or carrier protocol. They are transmitted between the VPN client and server and are ultimately de-encapsulated at the receiving end. Which statement best describes the function of voluntary tunneling?

  • A Managing of connection setup is carried out by the VPN client
  • B Authenticates clients and relates them with certain VPN servers using logic built into the broker's device
  • C Details of the VPN server's connectivity from the VPN clients are concealed
  • D VPN connection is managed between the client and a VPN server
Explanation

Voluntary tunneling is created at the user’s request, typically by VPN client software. The VPN client therefore initiates and manages connection setup, unlike compulsory tunneling, in which a network access device establishes the tunnel without client choice.
