RE: Sniffing RFID ID's ( Physical Security )

["Ng, Kenneth \(US\)" <kenng () kpmg com>]

As with a thousand other technologies, no one ever takes security
seriously until someone gets whacked over the head with a million dollar
loss or a bad news story on the front page of the New York Times.   Time
and time again we see the same kind of mistakes repeated in different
technologies.  We see people picking the cheaper technology (all the
security is the same isn't it?)  and hiring cheap programmers (all
programmers have security backgrounds, don't they?) and deploying with
insane deadlines (they wouldn't take security shortcuts to make the
deadline, right?).

Well.. Yeah.  That *would* make sense.

Unfortunately, some beancounter would likely realize they can shave
$0.02 per card by doing it the easy way, or that they can save $40K by
hiring a bonehead designer rather than a clued crypto geek.

If all software was actually designed and implemented to the "Surely it
would"
standard, most of the people on this list, both black and white hats,
would be unemployed.  Fortunately for our collective ability to cover
our rent checks, almost all software has "Surely they *didn't*" flaws in
it....
