Question 80

Wired Equivalent Privacy (WEP) is a security protocol for wireless local area networks (WLANs). It has two components, authentication and encryption. It provides security equivalent to wired networks for wireless networks. WEP encrypts data on a wireless network by using a fixed secret key. Which of the following statements are true about WEP? Each correct answer represents a complete solution. Choose all that apply.

  1. WEP uses the RC4 encryption algorithm.
  2. Automated tools such as AirSnort are available for discovering WEP keys.
  3. It provides better security than the Wi-Fi Protected Access protocol.
  4. The Initialization Vector (IV) field of WEP is only 24 bits long.
