Essay about Wireless Network Security - 3575 Words

Introduction Wireless networks have grown in popularity. This is largely due to the increase in the value of a network as more users are attached to it. The value added to a network by nature of connecting more devices to it, is summarized in Metcalfs law. Metcalfs law states that if you connect any number, n, of machines - whether computers, phones or even cars - and you get n squared potential value.[1] The incredible growth of the Internet seems to validate Metcalfs law. It then seems reasonable that eliminating physical constraints to connecting to a network would provide value by allowing more devices to be connected to a network regardless of physical location. Wireless networks provide that ability. Wireless†¦show more content†¦It has been omitted from them PAN topography. I believe this is an oversight, and I will provide rational for this in a later section. Each wireless technology has unique security risks and concerns. Many of the risks and concerns are shared across technologies. In order to provide even a brief overview of each technology, topography, and the risks inherent to each would require a document far larger than is specified for this project. Therefore, this document will focus on the 802.11 standard as used in the PAN and LAN topographies. Figure 1 ? Types of Wireless Networks [4] The Wireless Market ?Over the past ten years or so an alternative to wired LAN structures has evolved in the form of the Wireless LAN. The first generation Wireless LAN products, operating in unlicensed 900-928 MHz Industrial Scientific and Medical (ISM) band, with low range and throughput offering (500 Kbps), subjected to interference came to market with few successes in some applications. But they enjoyed reputation of being inexpensive due to break through development in semiconductor technologies, on the other hand the band become crowded with other products with in short period of time leaving no room for further development. The second generation in 2.40-2.483 GHz ISM band WLAN products boosted by the development of semiconductor technology was developed by a huge number of manufactures.
