I was thinking the other night of the opening sequence of the 1990 movie The Grifters where John Cusack makes a living cheating bartenders by convincing them that he proffered them a $20 bill for a drink when they only gave him change for a 10. Even when I saw the movie in 1990 I didn’t see how Cusack could steal enough to make it worth his while, especially measured against the risks of arrest or bar room vigilante justice. Each con must have taken at least an hour to set up, execute and then move on to another bar, limiting Cusack’s take to about $8.50 an hour ($10 in change, minus the estimated 1990 cost of a beer.)
Jim Thompson wrote the novel that became The Grifters movie in the 1950s, when $9 or $10 an hour was a decent take, especially considering that the income was tax free. But even in 1990, much less 2008, Cusack’s con was obsolete. I doubt than anyone has pulled it for years, except as a stunt on a spot basis to defray the high cost of drinking.
The point of this story is that when it comes to security, maybe our focus should not be on trying to track down and arrest all of the con artists, but make their efforts obsolete. To be fair, it was 40 years of bad monetary policy that inflated Cusack out of a job. But I wonder how it would be possible to get beyond reactive cops and robbers IT security and instead develop preemptive processes and techniques that make today’s viruses, intrusions, worms, phishes, and cons beside the point.
