Wireless networks in the lives of people at work, at home,
and in public places, plays a decisive role. Given the widespread
demand for wireless networks, providers deploy wireless local area
networks (WLAN) to provide access to broadband Internet Within the
range of a public wireless LAN hotspot such as in airports or hotels,
users can access their e-mails and browse the Internet either for free
or, most often, against a fee. However, as the number of users rises, so
does the risk that users may misbehave. Misbehaving users can to a
large extent increase their share of bandwidth at the expense of other
paid users by slightly modifying the driver of the network adapter. As
the use of such networks grows, users will demand secure yet
efficient, low-latency communications. Intruders’ detection is one of
the key techniques that can be used to protect a network against
outsiders. Many Intrusion Detection Systems (IDSs) have been
designed for wired networks. Unfortunately, most of these IDSs do
not give the expected results when used with wireless networks and
are especially poor at addressing the Media Access Control (MAC)
layer problem. In this sheet, we present the design and implementation
of an IDS tool that is chosen for WLANs and addresses misbehavior
at the MAC layer properly.
