  2. Enterprise Access Points AP = Access Point There’s 1 in this room Similar to your wireless router The AP is wired to a switch in a switch closet or data center Modern day AP technology gets power over Ethernet

  3. Wireless Concerns What is a concern with wireless networks? What are some good practices when using public wireless? What is a concern with wireless networks?

  4. MiFi Devices One side is a wireless LAN The other side is connected to a cellular service What is a disadvantage of this technology?

  5. MiFi Devices 3G versus 4G (standards almost don’t matter) 4G LTE (Long Term Evolution) = peaks of 50 Mbps 3G = minimum 200 Kbps 4G = minimum 100 Mbps for phones/tablets and 1 Gbps for MiFi

  6. MiFi Devices What’s next? 5G Speeds of up to 10 gigs per second

  7. Bluetooth Devices What bluetooth connections do you make regularly? What is the security of a bluetooth device? (Cayla) https://www.youtube.com/watch?v=QQWbOeg2lpk https://www.youtube.com/watch?v=OkYVSag-uik

  8. Exercise Swap out your Raspberry Pi SD Card for the Kali SD Card Start your Raspberry Pi Username is root and password is toor Connect your Raspberry Pi to your new wireless network Open terminal and type nmap -sV 192.168.1.0/24
