Abstract

This paper proposes a security architecture for an intelligent energy consumption prediction Internet-of-Thing (IoT)-based system, looking to protect sensitive data and ensure reliable operation. The proposed model is a multi-layer security architecture addressing the security requirements specific to non-residential sites (office buildings, hospitals, educational facilities), with functional components designed to mitigate the associated risks. By combining the edge-level processing, end-to-end encryption, multi-layer intrusion detection, and KPIdriven monitoring, the proposed model addresses emergent threats while ensuring a balanced performance vs. the security ratio. Furthermore, the performance indicators are defined to evaluate the effectiveness of the architecture. The paper also presents the optimization options in respect to emergent threats, as well as the potential impact of the proposed security functions on the overall performance of the designed system.
