Breaking into the Vault: Teaching security concepts with help from a BeagleBone Black

I was invited to put on an hour-long workshop on cyber as part of a STEM weekend program for high school students. Unfortunately, I didn’t have access to a lot of resources to make this completely hands-on for them, but I had an interesting idea that I wanted to try out.  I presented them with the following scenario:

Our friends at Navy have given us a challenge.  They have vault, represented by the box I made, that contains something really valuable.  We currently have no way to get access, but our intel team has provided us with one piece of info:  there is some kind of industrial control system (ICS) that’s in charge of giant vault door.

I have the students walk me through how they’d go about finding more information about the structure.  Some tell me that they’d try to break the door down, but I inform them that the vault door is made of unobtanium and is resistant to any physical attack.

I used a Beaglebone Black as my ICS machine and connected it to a small servo to control the opening of the door.  The vault is made of fiberboard.  Lots of credit goes to Ed Skoudis for the inspiration from his CyberCity project.
