High school teacher asks class to plan terror attack - CNN.com
I'm not sure high school is the proper place for this type of assignment, but it highlights a big part of implementing good security... You have to anticipate how the terrorists are going to attack you, and be able to prevent it. It is done in computer security all the time. The problem comes when you come up with an attack and have no good way to prevent it or anticipate it.
Do you think that this was a good assignment to get the students to think about security in their everyday lives? Do you think that they would come up or expose weaknesses that security personal can't easily defend against? Maybe they are trying to find out how evil the kids are? Or do you think that the teacher was trying to come up with ideas to implement... that would be a good movie idea.
*I wouldn't write down your own ideas if you have any, you don't want to get investigated.
