摘要：The rapid proliferation of wireless networks and mobile computing applications has changed the landscape of network security, the wireless networks have changed the way business, organizations work and offered a new range of possibilities and flexibilities; It is clear that wireless solutions are transforming the way we work and live. Employees are able to keep in touch with their e-mail, calendar and employer from mobile devices, but on the other hand they have introduced a new security threat. While an attacker needs physical access to a wired network in order to gain access to the network and to accomplish his goals, a wireless network allows anyone within its range to passively monitor the traffic or even start an attack. One of the countermeasures that can be used in order to allow us to know both the threats affecting our wireless network and our system vulnerabilities is the Intrusion Detection System. WLANs have a number of security-related issues. They are as follows: 1] Data interception 2] Denial Of Service (DOS) 3] Rogue APs. 4] Other 802.11 related security threats. WLANs typically encompass a relatively large physical coverage area. In this situation, many WAPs can be deployed in order to provide adequate signal strength to the given area. An essential aspect of implementing a Wireless IDS is to deploy it wherever a WAP is located. By providing comprehensive coverage of the physical infrastructure at all WAP locations, the majority of attacks and misuse can be detected.
