Green Lights Forever: Analyzing the Security of Traffic Infrastructure

The safety critical nature of traffic infrastructure requires that it be secure against computer-based attacks, but this is not always the case. The authors investigate a networked traffic signal system currently deployed in the United States and discover a number of security flaws that exist due to systemic failures by the designers. They leverage these flaws to create attacks which gain control of the system, and then successfully demonstrate them on the deployment in coordination with authorities. These attacks show that an adversary can control traffic infrastructure to cause disruption, degrade safety, or gain an unfair advantage. The authors conclude by making recommendations on how to improve existing systems and discuss the lessons learned for embedded systems security in general.
