Smart Grid AMI Cybersecurity: NERC CIP, NIST IR 7628, and the Meter Data Architecture

189

Security requirements across 3 NIST IR 7628 logical interface categories for smart grid systems

Advanced Metering Infrastructure connects millions of endpoints to utility back-end systems through a head-end server that, under NERC CIP-005, must be treated as part of the Electronic Security Perimeter. The Meter Data Management System that processes AMI data touches billing, outage management, and demand response simultaneously â€” each with different security classifications. Most utilities design the AMI network for operational efficiency and retrofit security, which is backwards. The architecture that satisfies NERC CIP-005, NIST IR 7628, and FERC Order 2222 simultaneously requires deliberate design from the meter outward.
