Overall this is a decent---very basic---primer on cybersecurity and I would give it 5 stars were it not for one critical thing: there is absolutely no support from NYU. Here is what I mean. Everything was going great until week 4. The final quiz asks the student to choose the risk level as low, medium or high for various types of threats. The problem was that we were told that this type of threat assessment based on the CIA model and the different types of assets depends on the entity/company, but all the information we are given is that it is a software company. Now, forget for a second that this is highly counter-intuitive to the student based on the learning material so far, because guess what? If a student is confused about the material they have a way to communicate with professor/teaching staff and clear the doubts right? Well, in Coursera you have a forum for each course, which is supposed to be how they deal with this---you can't well expects 1-on-1 communication for the nominal fee we are paying and the fact that there are potentially thousands of students enrolled at any point in time. But here is where I had a problem. When I went to the forum several people had the exact same doubt, and had posted a question about it a month ago. No reply from NYU in a month! I mean, it's not like the forum is inundated with questions that the instructors are having to struggle to answer. There are only a few questions and they all seem to have gone unanswered! So for a MOOC with thousands of students, which should have some high aggregate value NYU can spare, what? An hour a month? Two hours a month tops to answer questions? Not even a graduate TA to answer on Amoroso's behalf if he is too busy? This can't be anything other than neglect and apathy. They are dropping the ball and losing the chance to tackle some low-hanging fruit issues in their course. In my opinion, and others too, the final should not be multiple choice but have short answers with justifications for the choices. But if that's not going to happen at least answer our questions.
