Connected Car Cybersecurity

The modern automobile is a complex grid of network-connected hardware and software consisting of hundreds-of-millions of lines of code. And the evolution of automotive technology is only beginning. Connected cars will change life as we know it, and ignoring connected-car cybersecurity puts not only consumers’ private data at risk but also their lives.


Just one of many examples of connected-car exploits took place in 2015 when two security researchers hijacked an SUV by compromising its entertainment system. The researchers remotely manipulated the air conditioning, increased the stereo’s volume, activated and disabled the brakes, and even killed the vehicle’s accelerator as it drove down the freeway.


Multiple components make up a connected car -- hardware, software, mobile apps, Wi-Fi and Bluetooth connectivity, and the cloud. And each one presents a potential attack vector. Driver assistance, vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), vehicle-to-device (V2D), vehicle-to-grid (V2G), and autonomous vehicle technologies create a complex web of cybersecurity risk that automotive OEMs and tier one suppliers must manage as they design, develop and deploy connected-car features and services.


To keep drivers safe and protect private consumer information, carmakers and tier one suppliers need to take a risk-based approach to connected car cybersecurity. Various best practices published by industry associations call on the automotive industry to institute: governance to ensure compliance with regulations and internal policies, building security into the connected car lifecycle, security assessments that identify/remediate vulnerabilities, threat detection methods and processes, and incident response plans.
