This paper describes the most frequently exploited vulnerabilities of wireless networks that use the IEEE 802.11 standard is enumerated. Intrusion detection and prevention systems are proposed as an important line of defence in a multifaceted wireless network protection system. However, some concepts from the classical IDS theory must be redefined and there are many changes that these systems must be exposed to in order to operate correctly and efficiently in a wireless network environment. The importance of anomaly detection systems is especially stressed because of very specific attacks that are difficult to detect and respond to by misuse (signature based) detection systems.
