Final answer:
A rolljam attack is a connected vehicle risk that involves over-the-air access interception and enables remote access to the targeted vehicle system.
Step-by-step explanation:
A rolljam attack is a connected vehicle risk that targets keyless entry systems in cars. It is an over-the-air access risk where the attacker intercepts signals between the car and key fob, preventing the car from receiving the lock signal. This allows the attacker to later gain remote access to the car.
