In the past, what happened in your car typically stayed in your car. That is no longer the case. The influx of digital innovations, from infotainment connectivity to over-the-air (OTA) software updates, is turning cars into information clearinghouses. While delivering significant customer value, these changes also expose vehicles to the seamier side of the digital revolution. Hackers and other black-hat intruders are attempting to gain access to critical in-vehicle electronic units and data, potentially compromising critical safety functions and customer privacy.
Cybersecurity becomes a core product and value-chain issue
Cybersecurity has risen in importance as the automotive industry undergoes a transformation driven by new personal-mobility concepts, autonomous driving, vehicle electrification, and car connectivity. In fact, it has become a core consideration, given the digitization of in-car systems, the propagation of software, and the creation of new, fully digital mobility services. These services include arrays of car apps, online offerings, vehicle features that customers can buy and unlock online, and charging stations for e-vehicles that “talk” to on-board electronics.
Today’s cars have up to 150 electronic control units; by 2030, many observers expect them to have roughly 300 million lines of software code. By way of comparison, today’s cars have about 100 million lines of code. To put that into perspective, a passenger aircraft has an estimated 15 million lines of code, a modern fighter jet about 25 million, and a mass-market PC operating system close to 40 million. This overabundance of complex software code results from both the legacy of designing electronics systems in specific ways for the past 35 years and the growing requirements and increasing complexity of systems in connected and autonomous cars. It generates ample opportunity for cyberattacks—not only in the car but also along the entire value chain.
