  As the amount of data that needs to be processed in real-time due to recent
application developments increase, the need for a new computing paradigm is
required. Edge computing resolves this issue by offloading computing resources
required by intelligent transportation systems such as the Internet of Vehicles
from the cloud closer to the end devices to improve performance however, it is
susceptible to security issues that make the transportation systems vulnerable
to attackers. In addition to this, there are security issues in transportation
technologies that impact the edge computing paradigm as well. This paper
presents some of the main security issues and challenges that are present in
edge computing, which are Distributed Denial of Service attacks, side channel
attacks, malware injection attacks and authentication and authorization
attacks, how these impact intelligent transportation systems and research being
done to help realize and mitigate these issues.
