Kismet is an 802.11 layer2 wireless network detector, sniffer, and intrusion detection system. Kismet will work with any wireless card which supports raw monitoring (rfmon) mode, and can sniff 802.11b, 802.11a, and 802.11g traffic.
Anyone interested in gaining a deeper knowledge of wireless security and exploiting vulnerabilities will need a good set of base tools with which to work. Fortunately, there are an abundance of free tools available on the Internet. This list is not meant
