Wireless Intruder Detection System (WIDS) in Detecting De-Authentication and Disassociation Attacks in IEEE 802.11

Wireless network seen to be targeted from various kind of attacks. Various type of security mechanism was applied, such as WEP, WPA and WPA2. These security mechanisms were only protected the network from intruder in accessing internal network. However, those security mechanisms did not protect communication for wireless clients. This phenomenon leads to vulnerability that contributed to the frames using 802.11a/b/g/n standard. The management frames on 802.11a/b/g/n were sent unencrypted plain text, thus it can be spoofed and forged by intruder. The 802.11w was introduced to protect frames but still have legacy in wireless devices been used that is not supported with 802.11w. This research proposed a tool that can be used as a personal WIDS (Wireless Intruder Detection System). Furthermore, this research also introduced the mechanism to detect de-authentication and disassociation attacks on 802.11a/b/g/n enviroment.
