Abstract: While efficiency and real-time monitoring have significantly improved with the integration of Internet of Things (IoT) devices into smart grids (SGs), new cybersecurity vulnerabilities have also been brought about by this process. This study examines the security risks associated with IoTenabled SGs, emphasizing the possibility of cyberattacks that could interfere with grid operations or compromise sensitive data, as well as the use of IoT in certain industries, IoT standards, and the significance of individual protocols. These days, SG cybersecurity is essential to ensuring the global security of our energy networks. Presenting a thorough overview of the security issues, risks, and potential solutions for Internet of Things-based SGs is the aim of this paper. Our research focuses on network vulnerabilities, security needs, and cyber-attacks in SG applications to assess their effects on the network and provide guidance for future paths in cyber-security development.
