The kill switch is a bad idea

by billso on Thursday, 3 July 2008

Bruce Schneier pub­lished an arti­cle in Wired called I’ve Seen the Future, and It Has a Kill Switch. I agree with his basic premise — it’s a dan­ger­ous idea to include a kill switch in a net­worked device. It’s dif­fi­cult to keep a deter­mined cracker out of a well-defended net­work. It’s ludi­crous to design a device that can dis­abled by remote control.

OnStar call rep­re­sen­ta­tives can bring a stolen vehi­cle to a slow and gen­tle halt by remotely dis­abling the car’s fuel sys­tem. Infor­ma­tion Week arti­cle called Stop Thief!.

So how long will it take before some­one tries to shut down an OnStar vehi­cle, just to show they can do it?
