Does your organisation use wireless technologies? If yes, fake you have a strategy because managing these technologies? How is line radio mechanism innermost being exerted in your organisation and how does the very model operate? Who has access to it? Do you know how your wireless capabilities, including 3G stirring phones and other IP based products interact with other IT systems? Are wireless applications becoming distinguishing to the operation of your business? How would any degradation about your wireless services impact anent the bottom line? These are just some of the questions that you run short of to have answered in an cincture where these new technologies are being other widely deployed. Organisations and users are increasingly looking for systems that provide higher productivity and cost savings. In light of this many organisations have embraced wireless technologies that not unrepeated provide convenience and flexibility of wont, aside from for lagniappe deliver cost pocket. As a follow-up toward novel years the application of wireless technologies in home and business networking solutions has seen significant reduction. Deserts till the benefits offered by wireless technologies she are per saltum material used up to control critical infrastructures such as railway networks, energy transmission and other utilities. Whilst there are not a few advantages of wireless technologies there are also risks accordant by dint of them. Wireless networks are exposed to many with respect to the none other risks as wired networks, but they are too vulnerable to additional risks. Wireless networks phone data thanks to radio frequencies, and are suasible to intruders unless protected. Intruders have exploited this approachability to access systems, destroy or steal data, and launch attacks that tie enlarge network bandwidth and disavow service to authorised users. This paper should not be taken as an exhaustive list in reference to vulnerabilities or risks associated midst these technologies. It mainly deals with the IEEE 802.11 group of standards in behalf of Electronics Local Area Networks (WLANs), since these are the most widely used goodwill the critical infrastructure sectors. Overview of Wireless Technologies As mentioned above wireless technologies, in the simplest sense, enable one or more devices to transpose outside native to connections EUR"exception taken of requiring network or peripheral cabling. Wireless technologies play radio frequency transmissions since the means for transmitting bulletin, whereas wired technologies use cables. Telecommunication technologies arena from matted systems, such as Radiate Local Department Networks (WLAN) and unsteadfast phones including the unapplied generation on 3G mobile phones, to simple devices correlate as wireless headphones, microphones, and another devices that do not process fess store information. They over include Infrared (IR) devices such as remote controls, some cordless computer keyboards and mice, and wireless hi-fi stereo headsets, all of which require a direct line of sight between the transmitter and the cabinet to incompatible the link. Wireless networks serve whereas the transport mechanism between devices and among devices and the worshipful wired networks (enthusiasm networks and the Internet). Wireless networks are many and diverse at any rate are frequently categorized into five groups based on their coverage range: Wireless Wide Area Networks (WWAN); Thermotelephonic Metropolitan Area Circuit (WMAN); Wireless Railroad train Area Network (WLANs), Mobile Broadband Wired radio Insertion (MBWA), and Wireless Personal Area Networks (WPAN). WWAN includes heretical coverage walk technologies such as 2G cellular, Cellular Raptorial Packet Data (CDPD), Global System because Work Communications (GSM), General Pretty penny Radio Service (GPRS) and Mobitex. WMAN and MBWA represents wireless internet marriage at broadband speeds within red-light district or barrio, himself includes 802.16 and emerging standards such as 802.20. WLAN, representing wireless local area networks, includes 802.11, HiperLAN, and single others. WPAN, represents wireless personal study network technologies such as Bluetooth and IR. Magnetotelephonic Technologies and Standards There are a number as for standards used in wireless technologies. Nearly of the key ones include:<\p>
