Security in advanced metering networks (AMI): Threats, mitigation and strategies in the context of Smart Grids

Abstract

Smart grids have revolutionized the electric sector with innovative solutions in generation, transmission, and distribution; however, the security of the final consumer-connected chain has historically been neglected. This article analyzes security threats in Advanced Metering Infrastructure (AMI) networks and proposes mitigation strategies to ensure their integrity and reliability. The objectives are to identify and analyze security threats in AMI networks, evaluate their potential impact, and discuss current strategies to mitigate associated risks, providing recommendations to enhance the security of these networks within the context of smart metering. The methodology included a comprehensive review of existing literature on AMI network security, identification of threats such as cyber-attacks, physical intrusions, and communication vulnerabilities, assessment of the potential impact of these threats, and development of improvement proposals based on best practices and emerging technologies. The analysis revealed significant threats such as tampering, unauthorized access, denial of service (DoS) attacks, command injection, and sniffing. Identified mitigation strategies include advanced encryption, strong authentication mechanisms, continuous network monitoring, and physical security measures. Security in AMI networks is crucial for the safe and reliable operation of smart grids, highlighting the need for multidisciplinary approaches. Current technologies and strategies are effective, but it is essential to continue developing innovative and adaptive solutions to address emerging threats. Implementing robust security practices will not only protect the electrical infrastructure but also foster consumer trust and improve the resilience of smart grids against potential attacks.
