The term wireless network is a combination of broadband ( internet provider ) devices and wireless (access points and nodes) connections. The marriage creates the Wireless Local Area Network (WLAN) on the customer’s premise. The communication medium of the WLAN is radio waves. Security on the WLAN comes in two variations and each has its specific method of authentication: “Wired Equivalent Privacy (WEP, now insecure), Wi-Fi Protected Access (WPA, WPA2), to secure wireless computer networks. Many access points will also offer Wi-Fi Protected Setup, a quick (but now insecure) method of joining a new device to an encrypted network.” To crack a wireless network, an individual would need to find a vulnerability and exploit the vulnerability to gain access, which is called web cracking. There are two types of cracking methods: passive and active. The latter is easier to crack than the former. WEP and Wi-Fi Protected Access have different cracking tools. Several known WEP cracking tools are Aircrack, Kismet, WEPCrack and WebDecrypt. WPA cracking tools are Cain & Abel and CowPatty.
