Definition (Class Summary)
WEP (Wired Equivalent Privacy) is a security protocol for wireless networks, it is the most common protocol in ordinary networks. Security protocols like WEP, WPA or WPAII, DES, VPN are in charge of encrypting the information that its transmitted from the network. Without this encription anyone could easily access the network and even watch what you are doing.

Nevertheless WEP its not difficult to crack, you can easily crack it with a brute force attack with KisMAC trunk. WEP has three options which allow different kind of security encriptions. Off (no security) 64-bit (weak security) 128-bit (fair security). info gotten from http://kb.netgear.com/app/answers/detail/a_id/1141/~/what-is-wep-encryption-for-wireless-networks%3F
