QUES: Denial of service attacks are designed to make a machine or network resource unavailable to its intended users. Attackers can deny service to individual victims, such as by deliberately entering a wrong password enough consecutive times to cause the victim account to be locked, or they may overload the capabilities of a machine or network and block all users at once. While a network attack from a single IP address can be blocked by adding a new firewall rule, many forms of Distributed denial of service (DDoS) attacks are possible, where the attack comes from a large number of points and defending is much more difficult. Such attacks can originate from the zombie computers of a botnet, but a range of other techniques are possible including reflection and amplification attacks, where innocent systems are fooled into sending traffic to the victim.

QUES: The financial crisis was not widely predicted by mainstream economists except Raghuram Rajan, who instead spoke of the Great Moderation. A number of heterodox economists predicted the crisis, with varying arguments. Dirk Bezemer in his research credits (with supporting argument and estimates of timing) 12 economists with predicting the crisis: Dean Baker (US), Wynne Godley (UK), Fred Harrison (UK), Michael Hudson (US), Eric Janszen (US), Steve Keen (Australia), Jakob Brchner Madsen & Jens Kjaer Srensen (Denmark), Kurt Richebacher (US), Nouriel Roubini (US), Peter Schiff (US), and Robert Shiller (US). Examples of other experts who gave indications of a financial crisis have also been given. Not surprisingly, the Austrian economic school regarded the crisis as a vindication and classic example of a predictable credit-fueled bubble that could not forestall the disregarded but inevitable effect of an artificial, manufactured laxity in monetary supply, a perspective that even former Fed Chair Alan Greenspan in Congressional testimony confessed himself forced to return to.
