Threat Modeling of Wireless Attacks on Advanced Metering Infrastructure

Abstract

Cyber physical systems are playing an essential role to increase the efficiency of integrated computational and physical elements. Especially, Advanced Metering Infrastructure proves to be useful for customers and consumer companies for efficient usage of energy and its cost calculations. However, such systems are more prone to cyber-attacks because of frequent real time communication between the providers and customers. The wireless and wired networks are used as the source of communication between the various components of AMI. In this study, we have done threat modelling to identify possible wireless attacks to compromise the AMI assets. We have used STRIDE and DREAD models for threat modelling. One of the major contributions of this study is classification and risk ratings of wireless attacks using STRIDE and DREAD models.
