There are many concepts in cybersecurity that can be aided by creative thinking skill. Take for example a PSK (pre shared key) exchange between wireless device and a router that allows you to connect to the internet and watch Netlifx or cute cats on the Internet.
To look at this process imagine you (station) are going to the secret Pub (access point) called Tribeca (ESSID) where they ask you for the password to get in. You knew in advance what kind of place it was - it had a huge banner advertising its services (beacon) and security measures (WPA2) were not a surprise for a guy willing to visit (probe request) that sort of place - you had a password (PSK) in advance after all. Bouncer (authentication server) on the door asks for the password (PSK) , and unless you have it, you cannot come in because what happens is "the station and the authentication server negotiate and authenticate until both sides are convinced that they are talking to whom they expect and that each side knows the proper secrets. At this point, the authentication server sends an EAP success message" opens the door and invites you to come in.
From this point on you are connected to the network! This happens within milliseconds when you enter a vicinity of a known "WiFi" in simple terms. What is interesting is that the device you carry in your pocket will send probe requests with saved connections all the time, authenticating automatically to the places you have used WiFi in. So, yeah if you have ever connected to Tribeca chances are this information can be easily captured with the use of wireless adapter in a monitor mode and create a profile of what kind of person you might be. Have you connected to Shopping Center-WiFi, ate at the restaurant-WiFi, went to the Library-WiFi on your lunch break to came back to work-WiFi within 2 miles from Home-WiFi? All conveniently mapped with the use of www.wigle.net.
If I had asked you years ago if you would agree to have your location information exposed for others to see would you say yes? I am not trying to make anyone anxious but point out that with the use of technology we need to consider being comfortable with giving up on certain amount of our privacy to make our lives easier in 2018.
