The wide use of Wireless Local Area Network (WLAN) has required the increase of Wireless Intrusion Detection System (WIDS) technology to focus on protecting the wired and wireless infrastructures from internal and external attacks. This book explores the different alternatives to design and implement an Embedded Intrusion Detection System (IDS) in order to protect a multi services wireless network. The targeted IDS must have a small size in order to be integrated in different wireless devices, low cost in order to be placed in many places of network, and has good performance to cover the data...
