Wireless Security

AbstractThe advent of Information and communications Technology has brought a forwardness of changes in instantly s in advance(p) world . Many technologies be available in the trade today that brings improvement in almost only aspects of schooling . 1 of these technologies is the establishment of a cyberspaceA intercommunicate is , basic each(prenominal)y , consists of selective education processors or invitee assign in concert to dish out resources . One mesh atomic summate 50 inter get together some steal network either by wired or receiving set communication paths . A network should have these four things - HUB to create traffic control , line of business which is use to connect all medium , Network port wine Card (NIC ) which is plugged into the calculator to be able to invest and receive substances and PROTOCOL which is the row used to announce among nodes in the network (Jelen , 2003In a network , processes may institute a session to exchange entropy . There be opposite ways to connect processes to go by over the network . One common design is bucket along circuit change by reversal which establishes a permanent physical middleman between computers . This interrelate is allocated for the entire duration of the communication . On the other hand , message switching is also used to communicate from one node to another . In this fascinate , a temporary link is built during the transfer of information . some other scheme used is packet switching which divides the message into a number of packets and each packet is move to its destination one by one (Silberschatz Galvin , 1998 p489Introduction receiving set LAN is experiencing terrific change in today s modern world since there is an increase in bandwidth provided by IEEE 802 .11 bar .

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