Securing Electronic Control Units (ECUs) in Autonomous Vehicles
Industry: Automotive
Electronic Control Units (ECUs) are critical components of autonomous vehicles (AVs) that control crucial systems, like braking, acceleration, and steering. These embedded systems communicate via Controller Area Network (CAN) bus or Ethernet and operate independently of an OS. Internal Combustion Engine (ICE) vehicles typically average about 70 ECUs, whereas AVs rely on hundreds of ECUs to process data from various sensors necessary to navigate and react to current road conditions.
Challenge
ECUs are most commonly programmed in languages like C and C++, leaving these systems susceptible to memory safety vulnerabilities. One of the most prevalent memory safety issues in ECUs is buffer overflow vulnerabilities. These occur when data is written beyond the bounds of allocated memory, which can lead to unauthorized access and control. An attacker that exploits a memory-safety vulnerability in the ECU firmware could take runtime control and cause erratic vehicle behavior.
“From our perspective, adding RunSafe means we have more opportunity to shrink the attack surface and reduce overall risks for our customers since security is now already built into our product.”
