A Threat to Vehicular Cyber Security and the Urgency for Correction

In the past decade, technologies in vehicles have been rapidly advancing creating both a new type of "on the road" entertainment and safer environment while driving. Technologies such as anti-lock brake systems, steering assist, and in some cases autonomous driving, manufactures nearly eliminated the dangers of driving. To maintain the advances in safe technologies, it is vital to establish a strong security system for automotive networks and is crucial to advance the state of the art in automobile security. Motivated by this, one of the main goals of this research paper is to define a threat environment for CAR networks by discussing the existing security vulnerabilities and threats/attacks that an automobile network is currently facing. To address these security challenges, we also present a distributed firewall system to protect a CAR network from both internal and external networks.
