"Why care about denial-of-service attacks when there are so many privilege elevation and information disclosure threats we should be worried about? For one reason, DoS costs you money: in *aaS environments, there's not only the indirect cost of disrupting your legitimate users' access to the service, but also the more immediate and measurable cost of the bandwidth, storage, and processing power that the attack consumes (and that the platform provider will happily bill you for). We should all care about DoS for another, darker, reason too: a foreign power may someday use a DoS attack as an act of cyberwarfare or cyberterrorism against US critical infrastructure systems."
