CSO — Hacking is no longer just a game for tech-savvy teens looking for bragging rights. It is a for-profit business -- a very big business. Yes, it is employed for corporate and political espionage, activism ("hacktivism") or even acts of cyberwar, but the majority of those in it, are in it for the money."
So, security experts say, one good way for enterprises to lower their risk is to lower the return on investment (ROI) of hackers by making themselves more expensive and time-consuming to hack, and therefore a less tempting target. It's a bit like the joke about the two guys fleeing from a hungry lion. "I don't have to outrun him," one says to the other. "I just have to outrun you."
Of course, this only applies to broad-based attacks seeking targets of opportunity -- not an attack focused on a specific enterprise. But, in those cases, being a bit more secure than others is generally enough.
