Abstract

This work aims to show the features, utilities and facilities of VPN technology that has been increasingly used by companies around the world. The understanding of authentication methods, protocols, strengths and weaknesses of the system which includes its use is valuable information for its implementation in safe places that value for the security of information and not open-hand the flexibility of having access to them when required. The economy of those who use a VPN is one of the most significant advantage, because its implementation does not require a line used to link the desired points. Itself is a simulation of a Private Network in public what we know as the Internet. As Internet access is becoming cheaper and more commonplace, such as VPN solutions that can ensure privacy and security on a complex means of public access (with several branches, cable, fiber optics, wireless networks, routers, etc.) are increasingly most valued and important in the market agility and growth of traffic and access of information.
