Abstract- In this paper, we investigate some of the key security issues and challenges associated with next generation transportation systems. We analyze the flow of information associated with embedded systems-based transportation framework and smart vehicles. We have identified some of the key challenges that manufactures should deal with as it relates to cyber security threats (e.g., malwares, CAN bus communication, and GPS spoofing) for vehicular systems. Finally, we have explored the measures that the industry can adapt to mitigate those key concerns.

I. INTRODUCTION
Over the past several years, the automotive industry has evolved with technology in order to offer its customers many options such as remote starting devices, on board computers, GPS navigational systems, wireless phone connectivity and wireless sensor features. In doing so the automobile industry has opened the door to a realm of cyber related attacks against our vehicles [1]. The modern-day vehicle is loaded with many onboard embedded systems. These are networked with each other and data flows between them are enabled. These can lead to many of these systems being vulnerable to attacks [2]. The vehicular system vulnerabilities have become a topic of increased interest in transportation industry with the advent of autonomous vehicles and drones [3]-[5].
Vehicular Ad hoc Networks (VANETs) have been a topic of research that has gained traction in the automobile industry over the last several years. Modern VANETs facilitate Vehicle -Vehicle (V2V) and Vehicle -to-Infrastructure (V2I) communication. Vehicles can make use of these increased connectivity among vehicles for safety applications, mobile internet access, traffic information, etc.[6]. Many of the devices that are standard in motor vehicles being made today are vulnerable to attacks due to the nature of their wireless communication. Most of the consumers are unaware of the increased security risks which come with additional technology which can lead to information loss or even accidents [7]. Many of the exposed vulnerabilities to these systems have been detailed in several studies [1], [8]. VANETs rely on wireless communication in a peer to peer manner. There are two types of nodes associated with these systems one being Road Side Units (RSUs) and the other being On-Board Units (OBU). Attacks on these systems can...
