Cracking of wireless networks

Cracking of wireless networks is the defeating of security devices in Wireless local-area networks. Wireless local-area networks(WLANs) – also called Wi-Fi networks are inherently vulnerable to security lapses that wired networks are exempt from.Cracking is a kind of information network attack that is akin to a direct intrusion. There are two basic types of vulnerabilities associated with WLANs: those caused by poor configuration and those caused by weak encryption.
