"Connected Vehicles and Cybersecurity--A New Frontier of Risk"

Connected and Automated Vehicles (CAVs) could change how people view transportation and mobility. CAVs may provide numerous advantages, including enhanced service accessibility, reduced travel burdens, and safer transportation systems. Many of these benefits are currently feasible with partial vehicle automation, and they may increase as advanced automation continues to develop. However, CAVs also present new chances for cyberattacks to compromise vehicle security. If these risks are not addressed as new CAVs and technologies emerge, they could undermine many of the potential benefits of CAV adoption. Some methods of vehicle compromise may be more difficult to detect, particularly if the attack results in small alterations to the vehicle's driving behavior. Such attacks could be delivered via malicious software updates to automated or partially automated vehicles and remain undiscovered for long periods of time. Even minor shifts in driving behavior could cause major disturbances to the transportation network. Subtle changes can cause traffic congestion, excessive fuel use, and more. For example, if such an attack were deployed on all vehicles of a certain make and model, even slightly more aggressive driving may create a network-wide rise in delays, fuel consumption, and emissions without a visible source of the problem. Different types of cyberattacks could compromise CAVs. They can be classified as infrastructure-based, communication-based, or sensor-based. This article continues to discuss the risk of cyberattacks faced by CAVs.
