With recent DDoS incidents related to wikileaks, I can't help but feel that pretty much all sites online are very vulnerable to such attacks. Visa, MasterCard (to name a few) have shut down because of this.
So my questions are:
- Is DDoS such a powerful form of attack?
- What can a company do to deal with this situation?
EDIT: I think I might have phrased my question too "n00bishly". I know what a DDoS is (from wikipedia and other sites).
My real question is: Why are those Big companies NOT applying anti-DDOS techniques? Don't tell me that Paypal and MasterCard are not afraid of service down or attacks. I have looked over the cost of some of these solutions, but they don't seem that expensive at all compared to how much Paypal or VISA makes a year. The real question is why are they so unprepared? ( Or is the scale of the DDoS that much bigger than what has been expected?)
