As this is a masters-level course, arguably readying people for management, I would add a course or two on compliance. Too many security pros know how to secure a system but know nothing about security standards. If you cannot explain how what you have done complies with various standards, all your effort will be torn down.

A course on documentation would also be prudent. Knowing the difference between policies, standards, and procedures will help you in any interview for positions above entry level. Knowing qualitative from quantitative, and being able to talk about abstract security theory, would be good too.

And some law. Some basic course so you can talk about negligence and liability without sounding like a wikipedia page.
