Analysis of the PPTP and IPSec protocols in Virtual Private Networks

Sammanfattning: Today increasing numbers of individuals are working away from the ordinary workplace while still requiring access to the server located at the workplace. New technology is meeting this demand allowing for safe and secure transmission of the data over the Internet. The aim of this project is to analyse two protocols that are used within the Virtual Private Network (VPN) structure today, with the focus on installation, transmission speed on both Local Area Networks (LAN) and via telephone line and security aspects of the protocols. The results show that it is quite complicated to setup a VPN network and to get operational. The results also show that there are security compromises within the VPN structure that indicate that if proper precaution is not taken it may give a false sense of security, where the user believes that it is a secure communication when in reality it is not.
