Analysis of the security and privacy risks and challenges in smart cities’ traffic light system

Currently, the IoT network is the fastest growing network in the world that brings the smart cities revolution. The increase in the smart cities development poses several security and privacy risks. With the acceleration of times, we can now hastily observe the lack of privacy in our life. The major security and privacy issues occur because of either non-consideration of its security and privacy aspects or having inappropriate controls in place. Many of these issues could be resolved by applying advanced IoT-enabled solutions. This paper presents security and privacy risks and challenges against issues within traffic lights system, which is a complex and critical smart cities system. The paper also addresses a proposed secure and privacy-aware system for future traffic light system.
