I've been working on answering "WHY it's so easy to hack targets" It's way outside the lane of Small Wars but here is some link bait http://selil.com/archives/2880 of what I'm working on. Don't worry about all the other stuff the only thing that really matters is there are a whole lot of vulnerabilities with associated exploits (that will be zero days) that aren't even disclosed on any one day and that window moves through time. Only silly people say that Stuxnet had an unprecedented 4 zero days. On average 12 zero days are created every day.
