If you work for a company with an online presence long enough, you'll deal with it eventually. Someone, out of malice, boredom, pathology, or some combination of all three, will target your company's online presence and resources for attack. If you are lucky, it will be a run of the mill Denial of Service (DoS) attack from a single or limited range of IP addresses that can be easily blocked at your outermost point, and the responsible parties will lack the necessary expertise to overcome this relatively simple countermeasure. Your usual script kiddie attack against a site with competent network and server administration is fairly short. If you are unlucky, you'll experience something worse: A small percentage of attacks is from a higher caliber of black hat, and while more difficult to deal with, the individual generally bores easily and moves on.
