frontier of network security. The days when having a secure office network meant your servers were behind locked doors is long gone. Everyday companies must deflect outside attacks from people down the street and across the globe. One of the biggest threats is man in the middle attacks, where an outside party can intercept vital information being sent from one device to another before it reaches it’s destination. The solution to this problem lies in creating a Virtual Private Network, or VPN, to protect
Abstract: A virtual private network (VPN) technology creates an encrypted connection over a network. VPN is useful to exchange information between offices securely. VPN has advantages over traditional private networks and dedicated links. Tunneling techniques are used to implement VPN. This paper describes the various tunneling technologies like, IPSec, PPTP, GRE and L2TP used in virtual private network. It concludes by comparing these technologies and their use for given selection criteria. I.
Introduction VPN stands for Virtual Private Network. It provides a private network across the public network (Internet). This allows the user to transmit and receive data to the private network across Internet, like it is being directly connected to it. VPN has the characteristics of point-to-point and private link. To resemble a point-to-point link, the data is sent along with the routing information necessary to reach the destination through the public network. Data is encrypted and only the users
