Wireless Security

AbstractThe advent of Information and communications Technology has brought a get along of changes in straight off s in advance(p) world . Many technologies be available in the commercialize today that brings improvement in almost only aspects of learning . angiotensin converting enzyme of these technologies is the establishment of a cyberspaceA cyberspace is , basic resumelyy , consists of data processors or pommel depute in concert to trade resources . One entanglement pile inter merge some reveal network either through wired or tuner communication paths . A network should have these four things - HUB to realize traffic control , melody which is apply to connect all medium , Network embrasure Card (NIC ) which is plugged into the calculator to be able to pose and receive passs and PROTOCOL which is the spoken communication used to announce among nodes in the network (Jelen , 2003In a network , processes may institute a session to exchange education . There ar contrasting ways to connect processes to infract over the network . One common end is speed circuit exchange which establishes a permanent physical merge between computers . This subsume is allocated for the completed duration of the communication . On the other hand , message switching is also used to communicate from one node to another . In this final cause , a temporary link is built during the transfer of breeding . some other scheme used is packet switching which divides the message into a proceeds of packets and each packet is move to its destination one by one (Silberschatz Galvin , 1998 p489Introduction receiving set LAN is experiencing nasty change in today s modern world since at that place is an increase in bandwidth provided by IEEE 802 .11 bar .

This involves the use of wireless router which must possess a working network adaptor A broadband modem which is attached to the wireless router enables the sharing of a high-speed internet affiliation . This wireless router allows many computers to connect over WiFi link up (z .about .com /1 /7 /g /3 /wireless-diagram-1 .jpgSecurity Threats and IssuesThe figure downstairs shows the taxonomy of security attacks in WLANFigure 2 : Taxonomy of Wireless Attacks (Karygiannis Owens , 2002 , p24Network Security attacks are divided into two attacks - peaceable and active .
