The security aspects of wireless local area network (WLAN)

MetadataShow full item record
Wireless Local Area Networks (WLAN) are increasing in number in both home and business uses due to the convenience, mobility and affordable prices for wireless devices. Wireless technology allows the mobile stations to freely move within the range of Access Points without being physically connected to the wired network. Ideally, the WLAN gives mobility and flexibility to users in homes and hot spot environments, such as airports and campuses. However, WLANs have serious security problems because the wireless signal of the WLAN is broadcast through the air in all directions simultaneously. An unauthorized user can easily capture this signal using freeware tools to exploit WLAN vulnerability. This thesis provides an introduction to WLAN technology, security vulnerabilities in the WLAN, and the recommended countermeasures for the Software Metrics Laboratory in Ingersoll 158, in the Naval Postgraduate School, with particular emphasis on security concerns for the implementation of the WLAN extension to the existing wired LAN.
