Security of Mobile Devices and Wi-Fi Networks

Abstract

Along with the progress of times and the development of science and technology, mobile devices have become more and more popular. At the same time, an increasing number of Wi-Fi networks are being built for the demand of mobile devices. Therefore, the security between mobile devices and Wi-Fi networks became a main object in the IT area. The purpose of the thesis is to analyze security threats and give relative advises for all the mobile device and Wi-Fi network users. The thesis mainly talks about two types security issues. For individual mobile device users, the threats mainly come from the public Wi-Fi networks they are using to transmit important message or information. For enterprise Wi-Fi networks, the security focus on preventing organization from mobile devices attacks. In order to reach the security object for individual mobile device users and enterprise Wi-Fi networks, the purpose of security technologies are from three dimensions: confidentiality, integrity and authentication. As an example of a secure communication method for mobile device users to encrypted data transmission I implement a clientless SSL based VPN connection between a mobile device and a firewall. The thesis could be used as a security guide for mobile device users and Wi-Fi network organizations, helping them to prevent security from Internet attacks.
