Threats against sensors
As we saw in Chapter 1, sensors play a critical role in the ability of the vehicle to determine its current state and to apply the correct control, given a specific driving situation. Attackers who want to influence the vehicle’s ability in performing its functions will find that sensors form a rich attack surface. Vehicle sensors are often connected to the vehicle’s network, which can make them vulnerable to cyberattacks potentially leading to accidents or other safety issues. In addition, sensors in vehicles often collect and transmit data, which could be vulnerable to tampering or manipulation. Attackers could potentially alter sensor data to mislead the vehicle’s control systems or gain access to sensitive information.
We differentiate between two types of sensors, based on the level of exposure to external attacks [18]:
- Environment sensors: For example, Light Detection and Ranging (LiDAR), ultrasonic, camera, Radio Detection...
