IoT in Vehicles: The Trouble With Too Much Code

The threat and risk surface of internet of things devices deployed in automobiles is exponentially increasing, which poses risks for the coming wave of autonomous vehicles, says Campbell Murray of Blackberry.

To get a sense of how complicated today’s cars are, Campbell notes that while A380 airplane runs around four million lines of code, an average mid-size car has 100 million lines of code.

Statistically, that means there are likely many software defects. Using a metric of .015 bugs per line of code, that means cars with that much code could have as many as 150 million bugs, Campbell says in an interview with Information Security Media Group. Reducing those code bases is one way to reduce the risks, he says.
