For students asking me what courses to enroll I have one general advise; there are courses that are required for the MST degree and then electives. For sure you need to register for the first ones. For the latter, it is up to you what you like to study, what courses are of your interest and what you want to do with your degree. If you are interested in security, enroll to security classes, if you are interested in policy, enroll to policy classes and so on. The MST plan of study is very flexible and also very structured so you can decide what classes to take. Hence, please come for advise only for other topics such as independent studies etc.
