this is probably a very basic question and perhaps an old one. i searched but could not find... i have an internet accnt with a major provider. i use wifi in the house of course. maybe i'm just paranoid but i'm sure many people have also had this question. how secure is my work/web behavior on my macbook pro? how easy is it for someone to tap in to my connection? i have stealth mode enabled and allow only essential traffic. who can spy on me? how close do they need to be? etc etc... any help at all. thanks.
