Securing the foundation: the critical role of network security in smart city implementations

Prasad, Sharanya Vasudev (2025) Securing the foundation: the critical role of network security in smart city implementations. Global Journal of Engineering and Technology Advances, 23 (1). 069-076. ISSN 2582-5003

This article examines the critical role of network security in successful smart city implementations, highlighting how secure networking practices create the essential foundation for urban innovation. As municipalities worldwide embrace smart city technologies to optimize urban services and enhance quality of life, they simultaneously introduce complex cybersecurity challenges through the integration of formerly isolated systems into interconnected networks. The article explores multiple dimensions of smart city security, including the expanding attack surface created by distributed IoT networks, the application of zero-trust architecture principles to protect critical infrastructure, and the importance of real-time monitoring and anomaly detection. Additional areas of focus include encryption and authentication mechanisms for securing communications, standardization approaches that enable consistent security frameworks across heterogeneous systems, and the transformative benefits that become possible when robust security measures are implemented from the design phase. Through case studies and expert analysis, the article provides a comprehensive framework for municipalities to develop smart city initiatives that deliver innovation while maintaining appropriate protection for critical urban systems and citizen data.
