It's like giving someone only the key they need to enter one specific room, rather than the master key to the whole building. This means people or computer programs get just enough power to do their jobs and nothing more. This simple rule helps avoid a lot of trouble by making sure that if someone tries to do something they shouldn't, they can't go far.
