 In today’s connected automotive ecosystem, the Electronic Control Unit (ECU) has become the brain of the modern vehicle. It governs almost every function — from engine performance and braking systems to infotainment, navigation, and even communication between autonomous systems. While ECUs have revolutionized vehicle performance and comfort, they have also introduced a new and serious challenge: cybersecurity . What Is an ECU? An ECU is an embedded computer system that manages one or more of a vehicle’s electronic functions. A modern car can contain more than 100 ECUs , all connected through internal networks such as CAN (Controller Area Network) , LIN (Local Interconnect Network) , and FlexRay . These ECUs continuously exchange data to ensure smooth operation and optimal performance. The Growing Attack Surface As vehicles have evolved into smart, connected systems , ECUs have become attractive targets for cybercriminals. Attackers no longer need physical access to the car —...
