NERC-CIP’s most recent release, version 5, focuses primarily on BES substations and their critical Cyber Assets (CA), by establishing an Electronic Security Perimeter (ESP) around the substation’s control system. RAD’s Megaplex, a major building block in RAD’s Service Assured Networking (SAN) solutions for power utilities, is strategically located to manage all electronic access to the substation and the cyber assets within it from external and internal attacks.
This paper reviews Megaplex’ 3-tier ESP protection and outlines how it helps power utilities boost their compliance with NERC CIP 005 and 007 requirements.
