IoT Security on Smart Grid: Threats and Mitigation Frameworks

Abstract

The number of smart grid IoTs is expected to grow exponentially in the near future, as predicted by the analyst. The improvement of a smart grid IoT security system increases due to communication technologies used in traditional power systems. Smart grid IoTs include critical devices due to its complex architectures. Smart grid IoTs that are connected and controlled remotely through the internet are becoming more universal. As a result, homes and businesses have ever increasing attack surfaces on their networks. It can lead to security arrears, and large-scale economic damage when the confidentiality and integrity of the communication is broken down. These huge systems may be endangered to threats. Consequently, there is a lot of research effort to enhance smart grid security in government, industry, and academia. We present a broad survey supported by a thorough review of earlier work. Moreover, recent advances and corrective measures are presented on smart grid IoT security. In this paper, the threats and mitigation framework of the smart grid IoT are analyzed. This paper reviews the existing literature on the smart grid IoTs in energy systems. We focus on threat types and provide an in-depth discussion of the threat state of the smart grid. Explicitly, we focus on the discussion and scrutiny of network vulnerabilities, attack countermeasures, and security requirements. We focus to supply a deep understanding of threat vulnerabilities and mitigation framework and give a path on future research directions for threat in smart grid IoTs.
