Just because you CAN screw around with someone else's property doesn't mean you SHOULD. Although it can be exciting (especially at that age) to do something forbidden, he can suffer the consequences if caught. He might inadvertently harm the system and could wind up in serious legal trouble. It's like walking up to someone's front door, twisting the knob and discovering that they forgot to lock it when they left. That doesn't give him the right to enter the house, even if all he wanted to do was "look around". Turn the situation around: would he want someone hacking into his home computer because he didn't have it properly secured? Would they have the right to do it to him?
