ABSTRACT

Wireless technologies have become increasingly prevalent in our lives. A PDA allows you to access calendar, e-mails, addresses, phone numbers, and the Internet. Some services offer GPS capabilities that can pinpoint the location of a device anywhere in the world. Wireless technologies promise to offer features and functions that are even more advanced in the next few years. The flexibility and cost savings have influenced organizations to deploy this technology without realizing that security risks in wireless networks are equal to the sum of operating a wired network plus the new risks introduced as a result of the portability of wireless devices. Issues such as transmission security and authentication are the most likely topics of discussion by security experts. At this point, encryption and authentication protocols are available to bring wireless network security to the same high level as that enjoyed by wired networks. Methods are available to prevent every known type of attack on wireless networks including WLAN detection, eavesdropping, MAC spoofing, rogue APs, theft of service, and potential legal issues. The only type of attack that can still threaten protected WLANs is one that also remains unresolved for wired networks: DoS, which is an attack that prevents legitimate users from accessing a network by flooding it with traffic. This chapter discusses security issues and threats that have not been covered in previous chapters.
