  Frequently Asked Questions

  What are the main security standards for Wireless LAN?

  The primary standards discussed are WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and WPA2.

  Why is WEP considered highly insecure?

  WEP has severe vulnerabilities that allow it to be compromised with a 100% success rate using modern statistical attacks.

  What is "wardriving"?

  Wardriving is a methodology used to discover wireless networks and survey their security status while moving through a specific area.

  How can a WPA-secured network be protected from dictionary attacks?

  Protection is achieved by using a combination of a strong encryption protocol and a complex, non-obvious security key.

  What are common types of Wireless LAN attacks?

  Attacks are classified into passive (eavesdropping, brute force) and active (Denial of Service, Man in the Middle).
