Experimental Validation of a Zero-Trust-Based Layered Cybersecurity and Hardening Framework for Smart Metering and IoT Modem Infrastructures
Smart meters and Internet of Things (IoT) modems are now essential for remote monitoring and management in energy distribution systems, but they also widen the attack surface. Vulnerabilities span the hardware, firmware, communication, and data-management layers, and this study addresses them with a five-layer security...
