Border Collies are very protective of the family, and it sounds like she didn't get enough socialising when she was little. I would talk to a dog trainer. I also wouldn't tap her on the nose though. This likely won't help. What she needs is to learn that all humanes aren't bad. How I might handle it is ask people to give her treat when you see them, but before you start any training plans, I would talk to a trainer first. If she barks at the door bell you could train her to only give one warning bark!
