Cybersecurity Smart City: Securing IoT and Smart Infrastructure

The growth of smart cities has increased the use of IoT devices and smart infrastructure to improve urban living. However, this also creates serious cybersecurity challenges such as data breaches and cyber-attacks. Smart city systems depend on real-time data, making them vulnerable to security threats. Traditional centralized security methods are not sufficient for these complex systems. This paper proposes the use of blockchain technology to enhance cybersecurity in smart cities. Blockchain provides a decentralized and tamper-proof system to protect data integrity and privacy. The methodology includes IoT data collection, blockchain integration, and smart contracts for automation. It also ensures secure access control and transparency among stakeholders. The results show improved data security, system reliability, and faster threat detection. Overall, blockchain offers an effective and scalable solution for securing smart city infrastructure.
