2.1 Real World Applications

In the automotive sector, the increasing reliance on Ethernet for communication creates many vulnerabilities which can be exploited:

  • Electronic Control Units (ECUs)
    Communication between various ECUs that control essential vehicle functions such as braking, steering, and engine management.
  • Advanced Driver-Assistance Systems (ADAS)
    Real-time data exchange for features like collision avoidance, lane-keeping assistance, and adaptive cruise control.
  • Body Control
    Monitoring and controlling various electronic accessories in a vehicle's body. Locking the doors, seat belt warning systems, or dimming the interior lighting.
