Study of various intrusions and ids issues in wireless LAN

In any information system intrusions are the activities that damage the security and integrity of the system. The rapid enhancement in wireless network has changed the level of network security. So, past way of protecting the network with the firewalls are not sufficient to maintain network security in wireless local area network. There are many intrusion detection techniques and systems which are used for identifying the various types of intrusions in wired network but these techniques are inapplicable in this new environment of wireless network. So, there is need to search new architecture for protecting wireless network. In this paper we focus on wireless network, intrusions in wireless network, different Intrusion Detection Systems which are used to detect these attacks or intrusions and also the various IDS issues in WLAN.
