Executive Summary

The use of wireless networks is growing constantly, not only for public internet access in urban areas, but also to connect computer equipment where wired networks would be impractical. But wireless networks are vulnerable to numerous forms of attack, from breach of confidentiality to denial of service. Since more and more devices can take advantage of wireless networks, and a large number of businesses are relying on wireless network in their day-to-day operations, the potential consequences of these vulnerabilities are getting increasingly serious. While proprietary solutions do exist to address these challenges, they are often expensive and complex to use. This whitepaper describes a simple wireless intrusion detection system, or WIDS, that can be built and operated easily using cheap off-the-shelf hardware and open-source software.
