Wireless Network Security Essay -- Wireless Networks Technology Essays

Introduction radio communicates have grown in popularity. This is largely collectable to the increase in the value of a internet as more than holdrs are link to it. The value added to a net in travel along by personality of connecting more devices to it, is summarized in Metcalfs law. Metcalfs law states that if you connect any number, n, of machines - whether estimators, phones or even cars - and you posit n squared emf value.1 The incredible growth of the Internet seems to validate Metcalfs law. It and then seems reasonable that eliminating personal constraints to connecting to a network would raise value by totallyowing more devices to be connected to a network regardless of visible location. radio receiver networks provide that ability.Wireless networks operate over the full spectrum of network topographies. These topographies include Personal, Local, Controller, metropolitan, and grand sphere of influence networks. A Personal bowl meshwork (PAN) is the inter connection of data technology devices within the range of an individual person, typically within a range of 10 meters.?2 A Local Area engagement (LAN) is a group of computers and associated devices that share a common communication theory line or wireless link and typically share the resources of a single mainframe computer or server within a shrimpy geographic area (for congressman, within an office building).?2 A Campus Area Network (CAN) is a fiber-optic network that physically interconnects entire buildings into one demon network. While severally building may have several distinct LANs within it, all(prenominal) building represents a single node on the CAN. 3 A Metropolitan Area Network (MAN) is ?a network that interconnects users with computer resources in a geographic area or region big than that cover by even a large LAN but small than the area covered by a wide area network (WAN - explained next).?2 A huge Area Network (WAN) is ?a geographically scatter teleco mmunications network.?2 Wireless networks come in many configurations and use many technologies. attend 1 depicts an example of the wireless technologies and standards used for each of the networks types defined above. The simulacrum indicates two major(ip) categories of wireless technologies fixed and mobile. The figure also indicates 10 technologies in use Bluetooth, irDA, 802.11, IR LAN, IR Bridge, Ricochet, RF Bridge, Cellular, MCS and Satellite. Virtually all of these tec... ...e issues addressed in the 802.11i standard, third party software vendors are chop-chop creating and securities industrying wireless security services and third-party solutions. As the wireless commercialize matures, it will last increasingly difficult to ?crack? wireless network security.References1 http//www.seas.upenn.edu/gaj1/metgg.html - Metcalf?s fairness and Legacy2 http//www.whatis.com - Whatis?com3 http//www.lib.siu.edu/faq/network1.faq.html - LAN FAQ14 http//local.cips.ca/queencity/Event s/archivedEvents/2000-01/SpringSeminar01/kentonjanzen/sld003.htm - Canadian Information touch Society5 http//www.tml.hut.fi/Studies/T-110.557/2002/ document/zahed_iqbal.pdf - Wireless LAN Technology Current bring up and Future Trends6 http//www.athenasemi.com/market/index.html - Wireless Market Overview7 http//www.microsoft.com/technet/treeview/default.asp?url=/technet/columns/cableguy/cg0302.asp - Microsoft TechNet8 http//csrc.ncsl.nist.gov/publications/drafts/draft-sp800-48.pdf - Wireless Network surety9 http//www.whatis.com (war driving) ?
