PETER HOEY Security Watch Superscaled Security Advances in high-performance

computing have found their counterpart in new security threats. Yet there is an interesting twist in that computational expansion tends to be relatively predictable, whereas security challenges are typically introduced and mitigated (when possible) in a more chaotic fashion. Few would have surmised, for example, that spam would have exceeded 60 % of all email transmissions by the end of 2003, nor that detection software would require sophistication approaching Turing Test intelligence levels. It is useful, therefore, to consider some of the impacts of scaled-up computing on our overall security environment. Certain rules continue to apply to computational evolution. Moore’s Law (which anticipates processing power doubling approximately every 18 months while the equivalent price halve
