Automotive security is all about making sure that cars are protected from bad people and hackers who might want to steal them or drive them without permission. It uses things like special passwords, secret codes, and more to make sure that only the people who are supposed to have access to the car get to use it. It also uses sensors, cameras, and other technologies so that the car can detect if someone who shouldn't be in it is trying to get in. That way the car can alert the owners and the police so they can try to stop them before anything bad happens.
