How to explain Kerberos to your kids

Ever had to explain how Kerberos works to someone? With the help of this 4 part play from MIT, you can even act it out! Only wish I had come across this sooner when I was in the thick of it twice in my career: once when implementing Kerberos support on EMC's Celerra NAS server and the second time when implementing it for NFSv4.1 client in VMware's vSphere 6.0 ESXi. Another great tutorial on Kerberos that makes it easier to understand this otherwise complex security interaction is: Kerberos explained in pictures.

The interesting thing to note is that as a computer user, one may be using Kerberos a number of times a day, like when logging onto a computer or accessing a file or another resource on the network.
