4. Wireless Local Area Networks
IEEE defined the standards for wireless networking
intended to provide the functionality of Ethernet, wirelessly using radio waves

5. Issues Default Hardware Settings WEP Encryption Weaknesses
Mad-in-the-middle

6. Solutions WEP WPA/WPA2 MAC Filtering Disabled SSID Broadcasting
End-to-end Encryption

7. Wireless Personal Area Networks
Bluetooth was designed to be the basis of the Personal Area Network
(PAN) a way for devices within relatively close proximity to communicate wirelessly with one another

8. Issues Default Settings Passkeys Faulty Encryption Scheme - E0 Privacy
“Bluejacking”
“Bluesnarfing”

9. Solutions
