IA : Cyber warfare protection.
Really hot now, I have a friend who just got a MS in it.
I'd rather people get an MS in computer science with a specialty or minor in IA.
It's bad enough that students no longer get a universal education when they go to college. Most people treat universities as white-collar trade schools and focus most of their efforts just learning a trade.
To continue that at higher levels can only lead to narrowly trained people who are good at few things and can never quite see the big picture.
That large corporations are gullible enough to hire people with degrees in something so specialized is not a good sign either.
