A Survey of Intelligent Transportation Systems Security: Challenges and Solutions

Incorporation of intelligence is becoming an increasingly important part of the transportation system. Attacks on the transportation infrastructure have been limited, but as more vehicles become connected, the threat for cyberattacks increases and hence the need to secure Intelligent Transportation Systems (ITS) for individual vehicles and public transportation. Security of these systems is crucial for the safe and efficient transportation. Solutions can be introduced to address the vulnerabilities of systems, overcome the external threats to the systems, and to reduce the risks of attacks that can be faced by ITS. The purpose of this research is to provide a survey of the ITS security challenges and solutions that can be implemented to prevent and/or overcome security breaches to ITS. We also provide recommendations for implementation of improved security techniques and programs to protect ITS.
