Introduction: The proliferation of Internet of Things (IoT) devices in smart cities has introduced numerous benefits, including enhanced efficiency and improved quality of life. However, this increased connectivity also brings about significant security challenges. Securing IoT devices in smart cities is crucial to safeguarding sensitive data, infrastructure, and citizen privacy. This paper explores various security frameworks tailored to address the unique challenges posed by IoT devices in the context of smart cities. Problem Statement: IoT devices in smart cities are vulnerable to various security threats, including data breaches, unauthorized access, and malicious attacks. Traditional security measures are often insufficient to protect these devices due to their diverse nature, limited resources, and large-scale deployment. Without adequate security frameworks, the integrity, confidentiality, and availability of data transmitted and processed by IoT devices are at risk, threatening the reliability and safety of smart city services. Objective: The primary objective of this research is to evaluate existing security frameworks designed specifically for IoT devices in smart cities. By analyzing these frameworks, this study aims to identify their strengths, weaknesses, and applicability to real-world scenarios. Additionally, the research seeks to provide insights into effective strategies for enhancing the security posture of IoT deployments in smart city environments. Methodology: This research employs a systematic literature review methodology to identify and analyze relevant security frameworks for IoT devices in smart cities. A comprehensive search of academic databases, conference proceedings, and industry reports is conducted to gather pertinent literature. The selected frameworks are then evaluated based on criteria such as scalability, interoperability, resource efficiency, and resilience to emerging threats. Results: The analysis reveals a diverse array of security frameworks tailored to address the specific challenges of IoT devices in smart cities. These frameworks encompass various security measures, including authentication, encryption, access control, and anomaly detection. While some frameworks focus on specific IoT components or communication protocols, others offer comprehensive solutions for securing entire smart city ecosystems.The findings highlight the importance of adopting a multi-layered approach to IoT security, integrating both technical and organizational measures. Conclusion: Security frameworks play a vital role in mitigating the inherent risks associated with IoT devices in smart cities. By implementing robust security measures, stakeholders can enhance the resilience of smart city infrastructures and protect against cyber threats. However, achieving effective IoT security requires collaboration among government entities, industry stakeholders, and cybersecurity experts. Future research should focus on developing standardized frameworks, fostering information sharing, and addressing the evolving threat landscape.
