802.11 wireless standard

• IEEE 802.11is a set of standards for WLAN

4
Different 802.11 Standards
5
Encryption Schemes

• WEP(Wired Equivalent Privacy)
• - First scheme for securing 802.11
• WAP AND WAP2(Wi-Fi Protected Access)
• - Standard schemes used today
• WAP-PSK (Pre-shared key)
• - Used in home and small office networks

6
Wardriving Tools

• Tools used in different platforms

7
NetStumbler

• Tool used in windows

8
Attacking 802.11 networks

• Note Hacking others network without the
  permission of network owner is illegal 2.
• Penetration Testing tools are used
• Powerful Tool is BackTrack2
• -Linux live distribution for pen testing
• -Voted as 1 tool for pen testing3
• -more than 300 security tools

9
Backtrack2
10
Defenses

• Minimize signal exposure
• SSID (Network name)
• - Broadcasting SSID
• - Not broadcasting SSID
• Unique SSID

11
Conclusion

• I suggest everyone to implement WPA-PSK
  encryption with strong passphrases and unique
  SSID for their networks.
• In future we can expect a strong encryption
  scheme than WPA that will come into existence
