Part A –  Draw a diagram that reflects your own personal WiFi network.  Include any devices that that are on your WiFi network (things like modems, routers, any special equipment provided by your provider, firewalls, etc).  Be sure to include all peripherals that are also connected to your network including mobile devices, printers, smart TVs, or other IoT devices that you might use.  If you have Bluetooth devices connected to any of those – include them as well – showing the path of the connection.  If there are multiple people in your household – show their devices as well.  It is important that you note the proper placement of any countermeasures in your network (i.e. firewalls). Examples of a good network diagram are uploaded.

Part B-  After you have your diagram drawn – do an analysis of how secure your network is.  Going into settings on your computer, you can get a lot of information on the wireless protocol used, what networks you have connected to (and may have defaults to connect to automatically), etc).  What kind of wireless router do you have?  Are you happy with the router settings / configuration? If you could, would you change the architecture of your network or upgrade any of the equipment and or software on those devices to increase the level of security for your network?  Were you surprised by any of the settings that you found?
