Schneier on Security: Why Data Mining Won't Stop Terror
A good reference URL to cut-and-paste when "scanning internet traffic for terrorist plots" rears its head:
This unrealistically accurate system will generate 1 billion false alarms for every real terrorist plot it uncovers. Every day of every year, the police will have to investigate 27 million potential plots in order to find the one real terrorist plot per month. Raise that false-positive accuracy to an absurd 99.9999 percent and you're still chasing 2,750 false alarms per day -- but that will inevitably raise your false negatives, and you're going to miss some of those 10 real plots.


Also, Ben Goldacre saying the same thing: http://www.badscience.net/2009/02/datamining-would-be-lovely-if-it-worked/

on average across the AV industry, 40% block rates just after 0-hour of a new malware sample, rising to 60% after 5 days. sounds like the AV industry is losing, if this chart is valid. (via Terry Zink)
