WISP: a wireless information security portal

Abstract

M.Sc.Wireless networking is a fairly new technology that is important in information technology (IT). Hotels, Airports, Coffee shops, and homes are all installing wireless networks at a record pace, making wireless networks the best choice for consumers. This popularity of wireless networks is because of the affordability of wireless networks devices, and the easy installation [11]. In spite of the popularity of the wireless networks, one factor that has prevented them from being even more widespread can be summed up in a single word: security. It comes as no surprise that these two – wireless and security – converge to create one of the most important topics in the IT industry today [11]. Wireless networks by nature bring about new challenges unique to its environment. One example of these new challenges is: “Signal overflow beyond physical walls”, and with these kinds of new challenges unique to wireless networks, we have new security risks. Hence wireless networks lend themselves to a host of attack possibilities and risks. That is because wireless networks provide a convenient network access point for an attacker, potentially beyond the physical security controls of the organization [7]. Therefore it is challenging for managers to introduce wireless networks and properly manage the security of wireless networks, Security problems of wireless networks are the main reason for wireless networks not being rolled out optimally [1]. In this dissertation, we aim to present to both specialist and non–specialists in the IT industry the information needed to protect a wireless network. We will first identify and discuss the different security requirements of wireless networks. After that we shall examine the technology that helps make wireless networks secure, and describe the type of attacks against wireless networks and defense techniques to secure wireless networks. The research will concentrate on wireless LANs (Local Area Networks), and leading wireless LAN protocols and standards. The result of the research will be used to create WISP (A Wireless Information Security Portal). WISP will be a tool to support the management of a secure wireless network, and help assure the confidentiality, integrity, and availability of the information systems in a wireless network environment
