Re: I had to laugh
Small business networks will be the most vulnerable, not least because the boss will just buy and connect this crap without talking to their (external) IT people.
You say most, but I work in an understaffed enterprise environment (the default setting for enterprise environments). I am in the midst of implementing a set of network inventory tools and am uncovering so much stuff that no-one at the home office was aware much less managed, tracked or configured. Despite having implemented a variety of security restrictions on our wired and wireless networks, our local admins put all sorts of stuff on our networks because someone at their site went out and bought it. Same deal for software. The best thing about the situation is that I just have to turn the data over to someone else to take action. I do not believe my situation is in any way unique.
