I would discourage you from teaching your dog protective behavior. Dogs are "transparent" meaning they don't distinguish between their external actions and their internal motivations. If you reward your dog for a mean growl, he can't tell the difference between your reinforcement of his action, and what he was thinking at the time.
Breeders of dogs who participate in protection sports understand this thoroughly - these dogs have to be dogs that have excellent balance between aggressive behaviors, and the personality traits that allow them to be controlled.
Just yesterday I was talking to a kid in the grocery store who found out I was a dog trainer. He wanted me to train his pit bull to be "mean." I informed him that I was sorry, that pits were absolutely the worst possible dog to try to teach human aggressive behavior, even if I wanted to, or could. If I could break through the pit bull's "bombproof" breeding, then he'd be a liability. The first person the dog bites, guess whose house gets taken away, dog killed, and guess who insurance companies won't touch for the rest of his life?
The guy said, "Oh, I have a Beware of Dog sign." Nope, that just tells the law you knew ahead of time your dog was aggressive and you'll be even more liable.
Securty systems are good at home. Fences are good too. While walking the neighborhoods, I hear mace and those noisemaker things are good.
