I think you are kidding yourself if you think linux is invulnerable to any kind of attack.
Linux has its place, but i think a true IT professional would understand that technology is about meeting the requirements of the user.
In fact you kind of contradict yourself in that you say you need it.
Of course it might be easier to just go along the lines of apple (sorry you cant do that because i say you cant) or denial (nope cant be done, or "you must be doing it wrong").
