Just a quick note for anyone using or doing this specific activity, there are errors that I have reported that you should be aware of. For two of the scenarios I was given for the section 2.1.7 Activity: "Threat Model Analysis", the answers that I initially selected and should have been correct, were instead marked as incorrect. I had to select other options until I was able to get what it incorrectly thought was right before I could move to the next question. It clearly stated in the feedback for each that my initial answer was actually true, so there is a mismatch happening somewhere in the program. As it can take a bit of time for these things to get addressed, just consider that before blindly accepting the outputs are true.
