Aloof with strangers means they will pretty much ignore strangers. Like a lab is very affectionate towards strangers and immediately accepts them into the home, a corso won't be as interested in making friends with them. Ignore isn't really accurate though, as they might keep an eye on the stranger and they certainly won't ignore the stranger if he/she becomes aggressive or poses a threat of some kind. That's why you need the word aloof, I suppose. Basically they'll act like they couldn't care less about the stranger. Won't be friendly or nasty to them. Untill they get a reason to be either friendly or nasty. I have a question, what work was the cane corso designed for? I mean originally? I know people employ them for varying tasks now but why did the italians create this mastiff? Was it a boar dog? cattle dog? guard dog? All of the above?
