It's not ideal, but OTOH if the students have physical access to the network (a room with a network jack in it), then they certainly could do far worse things, like booting the client from a usb stick with their own malicious tools or sneaking a laptop onto the network. If you are practicing defense in depth, then you assume that even internal users might behave maliciously and set your security accordingly.
