  2. Introduction 現在無線WIFI主要使用WEP,WPA,WPA2加密模式。WEP無線加密模式有著最好的兼容性，無線AP無線網卡都支持此種加密，可是因此也留下了最容易破解的先天不足 02

  3. BackTarack It's evolved from the merge of the two wide spread distributions - Whax and Auditor Security Collection. By joining forces and replacing these distributions, BackTrack has gained massive popularity and was voted in 2006 as the #1 Security Live Distribution by insecure.org. 03

  4. Wireless Card 無線網卡 由于各種網卡采用的芯片不同，可能某些功能未能實現。推薦 Prisam 2 或 Atheros 芯片。IBM比電內置的無線網卡通常有兩種：Intel 或 IBM。IBM 用的就是 Atheros 芯片。不建議使用 Intel 芯片，因為其設計上的原因，抓封包有問題，而且不能順利發攻擊包。如果買 PCMCIA 網卡，推薦 Netgear WAG511，在這邊我們使用了D-link DWL-G122來作為實驗的網卡。 04
